+# yaLanTingLibs 国密SSL（NTLS）支持
+
+## 概述
+
+yaLanTingLibs 现已全面支持国密SSL（NTLS，National TLS），这是中国国家密码管理局制定的密码算法标准。通过集成 Tongsuo（铜锁）密码库，yaLanTingLibs 的 `coro_rpc` 和 `coro_http` 组件现在可以支持两种国密通信协议：
+
+- **GB/T 38636-2020 TLCP**：双证书国密通信协议（Transport Layer Cryptography Protocol）
+- **RFC 8998**：TLS 1.3 + 国密单证书模式
+
+这使得 yaLanTingLibs 成为首批支持国密SSL的现代C++20协程网络库之一，为需要符合国密标准的应用提供了高性能、易用的解决方案。
+
+## 背景
+
+### 什么是国密SSL？
+
+国密SSL（NTLS）是基于中国国家密码算法标准（SM2/SM3/SM4）的传输层安全协议。与传统的TLS协议使用RSA、AES等国际算法不同，国密SSL使用：
+
+- **SM2**：椭圆曲线公钥密码算法（用于数字签名和密钥交换）
+- **SM3**：密码杂凑算法（用于消息摘要）
+- **SM4**：分组密码算法（用于数据加密）
+
+### 为什么需要国密SSL？
+
+1. **合规要求**：在中国，涉及国家秘密、商业秘密和个人隐私的信息系统，需要采用国密算法
+2. **自主可控**：国密算法由中国自主研发，符合国家信息安全战略
+3. **标准化**：GB/T 38636-2020 和 RFC 8998 提供了标准化的国密通信协议规范
+
+### 应用场景
+
+- 政府信息系统
+- 金融行业（银行、证券、保险）
+- 关键基础设施
+- 需要符合国密标准的商业应用
+
+## 支持的协议模式
+
+### 1. GB/T 38636-2020 TLCP（双证书模式）
+
+TLCP（Transport Layer Cryptography Protocol）是中国的国家标准，采用双证书机制：
+
+- **签名证书**：用于身份认证和数字签名
+- **加密证书**：用于密钥交换和数据加密
+
+**特点：**
+- 符合GB/T 38636-2020标准
+- 支持单向认证和双向认证
+- 使用SM2/SM3/SM4国密算法套件
+- 默认密码套件：`ECC-SM2-SM4-GCM-SM3` 和 `ECC-SM2-SM4-CBC-SM3`，支持设置ECDHE_SM4_CBC_SM3和ECDHE_SM4_GCM_SM3
+
+### 2. RFC 8998 TLS 1.3 + 国密（单证书模式）
+
+RFC 8998 是IETF标准，将国密算法集成到TLS 1.3协议中：
+
+- 使用单一证书（简化证书管理）
+- 基于TLS 1.3协议
+- 支持国密算法套件：`TLS_SM4_GCM_SM3` 和 `TLS_SM4_CCM_SM3`
+
+**特点：**
+- 符合国际标准（RFC 8998）
+- 证书管理更简单
+- 性能优化（TLS 1.3的1-RTT握手）
+- 向后兼容TLS 1.3生态
+
+## 技术实现
+
+### 依赖库
+
+yaLanTingLibs 的NTLS功能基于 **Tongsuo（铜锁）** 密码库实现。Tongsuo（铜锁） 是由开放原子开源基金会（OpenAtom Foundation）孵化及运营的开源项目，基于OpenSSL 3.0.3分支，增加了对国密算法的完整支持。
+铜锁获得了国家密码管理局商用密码检测中心颁发的商用密码产品认证证书，助力用户在国密改造、密评、等保等过程中，更加严谨地满足我国商用密码技术合规的要求。
+
+**Tongsuo项目地址：** https://github.com/Tongsuo-Project/Tongsuo
+
+### 架构设计
+
+NTLS功能完全集成到 yaLanTingLibs 的现有架构中：
+
+- **条件编译**：通过 `YLT_ENABLE_NTLS` 宏控制，默认关闭，不影响现有代码
+- **统一API**：与标准SSL API保持一致的使用方式
+- **协程友好**：完全支持C++20协程，异步非阻塞
+- **零拷贝**：充分利用协程特性，实现高性能网络通信
+
+## 编译配置
+
+### 前置要求
+
+1. **安装Tongsuo库**
+   ```bash
+   # 从源码编译安装Tongsuo
+   git clone https://github.com/Tongsuo-Project/Tongsuo.git
+   cd Tongsuo
+   ./config --prefix=/usr/local/tongsuo \
+            -Wl,-rpath,/usr/local/tongsuo/lib64 \
+            enable-ntls
+   make -j$(nproc)
+   sudo make install
+   sudo ldconfig
+   ```
+
+2. **配置环境变量**
+   ```bash
+   export PATH=/usr/local/tongsuo/bin:$PATH
+   export LD_LIBRARY_PATH=/usr/local/tongsuo/lib64:$LD_LIBRARY_PATH
+   export PKG_CONFIG_PATH=/usr/local/tongsuo/lib64/pkgconfig:$PKG_CONFIG_PATH
+   ```
+
+### CMake配置
+
+在编译 yaLanTingLibs 时，需要启用SSL和NTLS支持：
+
+```bash
+cmake -B build -G Ninja \
+    -DCMAKE_BUILD_TYPE=Release \
+    -DYLT_ENABLE_SSL=ON \
+    -DYLT_ENABLE_NTLS=ON \
+    -DCMAKE_PREFIX_PATH=/usr/local/tongsuo \
+    -DOPENSSL_ROOT_DIR=/usr/local/tongsuo \
+    -DOPENSSL_INCLUDE_DIR=/usr/local/tongsuo/include
+
+cmake --build build
+```
+
+**关键配置选项：**

+);
+```
+
+## 证书管理
+
+### 使用Tongsuo测试证书（推荐用于开发测试）
+
+最简单的方式是直接使用Tongsuo源码中自带的测试证书：
+
+```bash
+# Tongsuo源码目录中的测试证书位置
+TONGSUO_SRC/test/certs/sm2/
+
+# 将测试证书复制到安装目录（CI中会自动完成）
+cp -r /path/to/Tongsuo/test/certs/sm2 /usr/local/tongsuo/ssl/certs/
+```
+
+这些证书已经包含了：
+- CA证书（`chain-ca.crt`）
+- 服务器签名证书和私钥（`server_sign.crt`, `server_sign.key`）
+- 服务器加密证书和私钥（`server_enc.crt`, `server_enc.key`）
+- 客户端签名证书和私钥（`client_sign.crt`, `client_sign.key`）
+- 客户端加密证书和私钥（`client_enc.crt`, `client_enc.key`）
+
+### 生成SM2证书
+
+如果需要生成自己的SM2证书，可以参考 [Tongsuo官方文档：使用 Tongsuo 签发 SM2 双证书](https://www.yuque.com/tsdoc/ts/sulazb)。
+
+以下是基本的生成步骤：
+
+#### 1. 生成CA私钥和证书
+
+```bash
+# 生成CA私钥
+tongsuo genpkey -algorithm SM2 -out ca.key
+
+# 生成CA证书
+tongsuo req -new -x509 -key ca.key -out ca.crt -days 365 \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=Test CA"
+```
+
+#### 2. 生成服务器签名证书（TLCP模式需要）
+
+```bash
+# 生成服务器签名私钥
+tongsuo genpkey -algorithm SM2 -out server_sign.key
+
+# 生成服务器签名证书请求
+tongsuo req -new -key server_sign.key -out server_sign.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=localhost"
+
+# 使用CA签名服务器签名证书
+tongsuo x509 -req -in server_sign.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out server_sign.crt -days 365
+```
+
+#### 3. 生成服务器加密证书（TLCP模式需要）
+
+```bash
+# 生成服务器加密私钥
+tongsuo genpkey -algorithm SM2 -out server_enc.key
+
+# 生成服务器加密证书请求
+tongsuo req -new -key server_enc.key -out server_enc.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=localhost"
+
+# 使用CA签名服务器加密证书
+tongsuo x509 -req -in server_enc.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out server_enc.crt -days 365
+```
+
+#### 4. 生成客户端证书（双向认证需要）
+
+```bash
+# 生成客户端签名私钥
+tongsuo genpkey -algorithm SM2 -out client_sign.key
+
+# 生成客户端签名证书请求
+tongsuo req -new -key client_sign.key -out client_sign.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=client"
+
+# 使用CA签名客户端签名证书
+tongsuo x509 -req -in client_sign.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out client_sign.crt -days 365
+
+# 生成客户端加密私钥和证书（类似步骤）
+tongsuo genpkey -algorithm SM2 -out client_enc.key
+tongsuo req -new -key client_enc.key -out client_enc.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=client"
+tongsuo x509 -req -in client_enc.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out client_enc.crt -days 365
+```
+
+#### 5. 清理临时文件
+
+```bash
+rm *.csr *.srl
+```
+
+**注意：** 生产环境请使用正式的CA机构签发的证书，并妥善保管私钥文件。
+
+### 证书文件组织
+
+建议的证书目录结构：
+
+```
+/usr/local/tongsuo/ssl/certs/sm2/
+├── ca.crt              # CA根证书
+├── server_sign.crt     # 服务器签名证书（TLCP）
+├── server_sign.key     # 服务器签名私钥（TLCP）
+├── server_enc.crt      # 服务器加密证书（TLCP）
+├── server_enc.key      # 服务器加密私钥（TLCP）
+├── client_sign.crt     # 客户端签名证书（双向认证）
+├── client_sign.key     # 客户端签名私钥（双向认证）
+└── chain-ca.crt        # CA证书链
+```
+
+## 认证模式
+
+### 单向认证
+
+服务器提供证书，客户端验证服务器身份：
+
+- **适用场景**：大多数Web应用、API服务
+- **配置**：`enable_client_verify = false`
+- **客户端**：只需要CA证书验证服务器
+
+### 双向认证（Mutual Authentication）
+
+服务器和客户端都需要提供证书：
+
+- **适用场景**：高安全要求的系统、内网服务
+- **配置**：`enable_client_verify = true`
+- **客户端**：需要提供客户端证书和私钥
+
+
+## 示例代码
+
+完整的示例代码位于：
+
+- **RPC示例**：`src/coro_rpc/examples/base_examples/ntls_server.cpp` 和 `ntls_client.cpp`
+- **HTTP示例**：`src/coro_http/examples/ntls_http_server.cpp` 和 `ntls_http_client.cpp`
+
+运行示例：
+
+```bash
+# 编译示例
+cmake --build build --target ntls_server ntls_client
+
+# 运行服务器（后台）
+./build/output/examples/coro_rpc/ntls_server &
+
+# 运行客户端
+./build/output/examples/coro_rpc/ntls_client
+```
+
+## 兼容性说明
+
+### 默认行为
+
+- **NTLS功能默认关闭**：不影响现有代码，需要显式启用
+- **条件编译**：通过 `OPENSSL_NO_NTLS` 宏控制，未启用NTLS时相关代码不会编译
+
+### 与标准SSL共存
+
+yaLanTingLibs 支持同时使用标准SSL和NTLS：
+
+- 标准SSL：使用OpenSSL，支持RSA/AES等国际算法
+- NTLS：使用Tongsuo，支持SM2/SM3/SM4国密算法
+
+两者可以共存，通过不同的配置选择使用。
+
+## 测试
+
+yaLanTingLibs 提供了完整的NTLS测试：
+
+- **CI测试**：`.github/workflows/ntls_test.yml` 自动测试NTLS功能
+- **端到端测试**：`scripts/run_ntls_e2e_tests.sh` 验证完整的通信流程
+- **协议验证**：可以使用Tongsuo自带的命名行与ylt的rpc或者http进行测试，具体参考：https://www.yuque.com/tsdoc/ts/hedgqf 使用方法
+ 
+## 相关资源
+
+- **Tongsuo项目**：https://github.com/Tongsuo-Project/Tongsuo
+- **GB/T 38636-2020标准**：国家密码管理局
+- **RFC 8998**：https://www.rfc-editor.org/rfc/rfc8998.html

+## 总结
+
+yaLanTingLibs 的NTLS支持为需要符合国密标准的应用提供了：
+
+✅ **完整的国密协议支持**：GB/T 38636-2020 TLCP 和 RFC 8998  
+✅ **简单易用的API**：与标准SSL API保持一致  
+✅ **生产就绪**：完整的测试、文档和示例  
+

+## 国密SSL（NTLS）支持
+
+yaLanTingLibs 现已全面支持国密SSL（NTLS），通过集成 Tongsuo（铜锁）密码库，`coro_http` 和 `coro_rpc` 组件现在可以支持两种国密通信协议：
+
+- **GB/T 38636-2020 TLCP**：双证书国密通信协议
+- **RFC 8998**：TLS 1.3 + 国密单证书模式
+
+详细使用说明请参考：[国密SSL（NTLS）支持文档](ntls_support.md)
+
 ## http 先连接再请求
 前面介绍的get/post 接口传入uri，在函数内部会自动去连接服务器并发请求，一次性完成了连接和请求，如果希望将连接和请求分开程两个阶段，那么就可以先调用connect 接口再调用async_get 接口。

 coro_rpc supports using OpenSSL to encrypt connections. After installing OpenSSL and importing yalantinglibs into your project with CMake's `find_package` or `fetch_content`, you can enable SSL support by setting the CMake option YLT_ENABLE_SSL=ON. Alternatively, you might manually add the YLT_ENABLE_SSL macro and manually link to OpenSSL.
 
-Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It’s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
+Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It��s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
+
+For one -way SSL authentication(server authentication only),you can use the `init_ssl` function before establishing a connection:The first parameter is the base path where the SSL certificates are located, and the second parameter is the CA certificate filename for verifying the server.
+
+Server-side configuration:
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "";  // Empty for one-way authentication
+ssl_conf.enable_client_verify = false;  // Disable client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+Mutual SSL Authentication For mutual SSL authentication(both client and server authentication),the client needs to provide its own certificate :
+
+```cpp
+    // Client-side mutual authentication
+    client.init_ssl("./",  // Base path
+                    "ca.crt",  // CA certificate for server verification
+                    "client.crt",  // Client certificate
+                    "client.key",  // Client private key
+                    "127.0.0.1"  // Server hostname for SNI
+    );
+```
+
+Server-side configuration for mutual authentication:
 
 ```cpp
-client.init_ssl("./","server.crt");
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "ca.crt";  // CA certificate for verifying clients
+ssl_conf.enable_client_verify = true;  // Enable mandatory client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
 ```
 
-The first string represents the base path where the SSL certificate is located, the second string represents the relative path of the SSL certificate relative to the base path.
+**Important Notes**:
+- The `enable_client_verify` flag enables mandatory client certificate verification
+- When mutual authentication is enabled, clients must provide a valid certificate signed by the CA specified in `ca_cert_file`
+- The hostname parameter must match the Common Name (CN) in the server certificate
 
 We also support NTLS if you enable it by CMAKE OPTION `YLT_ENABLE_NTLS`.

Subject: [PATCH 26/38] fix: SSL mutual authentication tests and certificate
 configuration

- Set is_ssl_schema_ = true in init_ssl() to ensure HTTPS protocol is used
- Update test URLs from http:// to https:// for SSL tests
- Add certificate copy to test working directory in CMakeLists.txt
- Fix CA certificate path from server.crt to ca.crt in RPC tests
- Add missing ca.crt, client.crt, client.key for mutual auth tests
- Update server certificates signed by CA

From 44146e8f06194ddbcab995b5f7487e7e718cf643 Mon Sep 17 00:00:00 2001
From: shenxuebing <shenxuebing@vip.qq.com>
Date: Thu, 9 Apr 2026 12:28:11 +0800
Subject: [PATCH 27/38] fix: SSL mutual authentication compatibility with
 OpenSSL 3.0 and TLS 1.3

Changes:
- Set SSL security level to 0 for test certificates (OpenSSL 3.0 compatibility)
- Change SSL context from sslv23 to tls for modern TLS
- Skip hostname verification for IP addresses (127.0.0.1, localhost)
- Update SSL client test to use ca.crt for server verification
- Handle TLS 1.3 post-handshake auth behavior in mutual auth tests
- Regenerate certificates with proper SAN extension for 127.0.0.1
- Add fake.crt/fake.key for testing invalid client certificates
- Remove unused fake_server.crt/fake_server.key

-# Introduction to coro_rpc Client
-
-## Base Usage
-
-class `coro_rpc::coro_rpc_client` is the client side of coro_rpc, allowing users to send RPC requests to the server. 
-
-Below, we will demonstrate the basic usage of rpc_client.
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-int add(int a,int b);
-Lazy<void> example() {
-  coro_rpc_client client;
-  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
-  if (ec) { /*check if connection error*/
-    std::cout<<ec.message()<<std::endl;
-    co_return;
-  }
-  rpc_result result = co_await client.call<add>(1,2);
-  /*rpc_result is type of expected<T,rpc_error>, which T is rpc return type*/
-  if (!result.has_value()) {
-    /*call result.error() to get rpc error message*/
-    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
-    co_return;
-  }
-  assert(result.value()==3); /*call result.value() to  get rpc return type*/
-}
-```
-
-You can use the `set_req_attachment` function to set the attachment for the current request. This is a piece of binary data that will be sent directly to the client without serialization. Similarly, you can also use `get_resp_attachment()` and `release_resp_attachment()` to retrieve the attachment returned by the RPC request.
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-void attachment_echo() {
-  auto ctx=coro_rpc::get_context();
-  ctx->set_resp_attachment(ctx->get_req_attachment());
-}
-Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
-  client.set_req_attachment(attachment);
-  rpc_result result = co_await client.call<attachment_echo>();
-  if (result.has_value()) {
-    assert(result.get_resp_attachment()==attachment);
-    co_return std::move(result.release_resp_attachment());
-  }
-  co_return "";
-}
-```
-
-By default, the RPC client will wait for 5 seconds after sending a request/establishing a connection. If no response is received after 5 seconds, it will return a timeout error. Users can also customize the wait duration by calling the `call_for` function.
-
-```cpp
-client.connect("127.0.0.1:9001", std::chrono::seconds{10});
-auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
-assert(result.value() == 3);
-```
-
-The duration can be any `std::chrono::duration` type, common examples include `std::chrono::seconds` and `std::chrono::milliseconds`. Notably, if the duration is set to zero, it indicates that the function call will never time out.
-
-## SSL support
-
-coro_rpc supports using OpenSSL to encrypt connections. After installing OpenSSL and importing yalantinglibs into your project with CMake's `find_package` or `fetch_content`, you can enable SSL support by setting the CMake option YLT_ENABLE_SSL=ON. Alternatively, you might manually add the YLT_ENABLE_SSL macro and manually link to OpenSSL.
-
-Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It��s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
-
-For one -way SSL authentication(server authentication only),you can use the `init_ssl` function before establishing a connection:The first parameter is the base path where the SSL certificates are located, and the second parameter is the CA certificate filename for verifying the server.
-
-Server-side configuration:
-
-```cpp
-coro_rpc_server server(2, 9000);
-ssl_configure ssl_conf;
-ssl_conf.base_path = "./certs";
-ssl_conf.cert_file = "server.crt";
-ssl_conf.key_file = "server.key";
-ssl_conf.ca_cert_file = "";  // Empty for one-way authentication
-ssl_conf.enable_client_verify = false;  // Disable client certificate verification
-
-server.init_ssl(ssl_conf);
-server.register_handler<your_function>();
-server.start();
-```
-
-Mutual SSL Authentication For mutual SSL authentication(both client and server authentication),the client needs to provide its own certificate :
-
-```cpp
-    // Client-side mutual authentication
-    client.init_ssl("./",  // Base path
-                    "ca.crt",  // CA certificate for server verification
-                    "client.crt",  // Client certificate
-                    "client.key",  // Client private key
-                    "127.0.0.1"  // Server hostname for SNI
-    );
-```
-
-Server-side configuration for mutual authentication:
-
-```cpp
-coro_rpc_server server(2, 9000);
-ssl_configure ssl_conf;
-ssl_conf.base_path = "./certs";
-ssl_conf.cert_file = "server.crt";
-ssl_conf.key_file = "server.key";
-ssl_conf.ca_cert_file = "ca.crt";  // CA certificate for verifying clients
-ssl_conf.enable_client_verify = true;  // Enable mandatory client certificate verification
-
-server.init_ssl(ssl_conf);
-server.register_handler<your_function>();
-server.start();
-```
-
-**Important Notes**:
-- The `enable_client_verify` flag enables mandatory client certificate verification
-- When mutual authentication is enabled, clients must provide a valid certificate signed by the CA specified in `ca_cert_file`
-- The hostname parameter must match the Common Name (CN) in the server certificate
-
-We also support NTLS if you enable it by CMAKE OPTION `YLT_ENABLE_NTLS`.
-
-## Conversion and compile-time checking of RPC parameters
-
-coro_rpc will perform compile-time checks on the validity of arguments during invocation. For example, for the following rpc function:
-
-```cpp
-inline std::string echo(std::string str) { return str; }
-```
-
-Next, when the current client invokes the rpc function:
-
-```cpp
-client.call<echo>(42); // Parameter does not match, compilation error
-client.call<echo>(); // Missing parameter, compilation error
-client.call<echo>("", 0); // Extra parameters, compilation error
-client.call<echo>("hello, coro_rpc"); // The string literal can be converted to std::string, compilation succeeds
-```
-
-## Connection Options
-
-The `coro_rpc_client` provides an `init_config` function to configure connection options. The code below lists all configurable options, which are optional with default values.
-
-```cpp
-using namespace coro_rpc;
-using namespace std::chrono;
-void set_config(coro_rpc_client& client) {
-  uint64_t client_id;
-  std::chrono::milliseconds connect_timeout_duration;
-  std::chrono::milliseconds request_timeout_duration;
-  std::string host;
-  std::string port;
-  std::string local_ip;
-  client.init_config(config{
-    .connect_timeout_duration = 5s, // Connection timeout duration
-    .request_timeout_duration = 5s, // Request timeout duration
-    .host = "localhost", // Server hostname
-    .port = "9001", // Server port
-    .local_ip = "", // Local IP address used to specify the local communication interface
-    .socket_config=std::variant<tcp_config,
-                 tcp_with_ssl_config,
-                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // Specify transport protocol and its configuration. Supported protocols: TCP, SSL over TCP, RDMA
-  });
-}
-```
-
-### RDMA Socket Configuration
-
-The configuration for IBVerbs socket protocol is shown below:
-
-```cpp
-struct ib_socket_t::config_t {
-  uint32_t cq_size = 128; // Maximum length of event notification queue
-  uint32_t recv_buffer_cnt = 8;                 // Number of buffers pre-submitted to receive queue. Each buffer defaults to 256KB, so a RDMA connection occupies 8MB memory immediately after establishment. More pending receive data will result in more buffers in the queue, up to max_recv_wr*buffer_size (where buffer_size is configured in buffer_pool). If upper layer doesn't consume data, sender will receive RNR (Receiver Not Ready) errors and retry continuously.
-  uint32_t send_buffer_cnt = 4;                 // default send buffer queue max size,
-  ibv_qp_type qp_type = IBV_QPT_RC;             // Default QP type
-  ibv_qp_cap cap = {.max_send_wr = 32,           // Maximum send queue length
-                    .max_recv_wr = 32,          // Maximum receive queue length
-                    .max_send_sge = 3,          // Maximum send scatter/gather elements. Only 1 needed without inline data. Use 3 segments when using inline data (default supports 3 scattered addresses)
-                    .max_recv_sge = 1,          // Maximum receive scatter/gather elements. 1 suffices with current buffer configuration
-                    .max_inline_data = 256};    // If packet size < inline data threshold and NIC supports it, small packets bypass buffer copy and go directly to NIC
-  std::shared_ptr<coro_io::ib_device_t> device; // Underlying IB device for RPC. Defaults to first device in list
-};
-```
-
-Simple RDMA activation examples:
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv(); // Use default configuration
-  cli.init_ibv({.recv_buffer_cnt=8}); // Use custom configuration
-```
-
-RDMA activation through config:
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
-```
-
-#### RDMA Device Configuration
-
-The `ib_device_t` manages the connection context and buffers required during the ibverbs transmission process. By default, it uses the global device `coro_io::get_global_ib_device()`, but users can also specify their own device.
-
-By modifying the configuration of `ib_device_t`, users can assign different network interfaces to RPC connections and use separate buffers.
-
-1. Modify the default device configuration
-```cpp
-  // The configuration only takes effect on the first invocation
-  coro_io::get_global_ib_device({ 
-    .buffer_pool_config = {
-      .buffer_size = 256 * 1024,  // Buffer size
-      .max_memory_usage = 4 * 1024 * 1024, // Max memory usage (allocation fails beyond this limit)
-      .memory_usage_recorder = nullptr; // nullopt means that memory usage across different devices will be counted together. If you want the memory pool to have independent memory usage tracking, you should assign a non-null std::shared_ptr<std::atomic<std::size_t>> as the recorder.
-      .idle_timeout = 5s // Buffers unused for this duration will be reclaimed
-  }
-  });
-  // ...
-```
-
-      2. Specify the RDMA NIC to use when initializing the connection
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
-  });
-```
-
-      3. Create and use your own `ib_device_t`
-```cpp
-  auto dev = coro_io::ib_device_t::create({
-      .dev_name = "",  // If dev_name is empty, the first device in the device list will be used.
-      .port = 1,       // Manually specify the NIC port number.
-           .use_best_gid_index = true,  // Automatically find the best GID index for this device.
-      .gid_index = 0,   // Manually specify the GID index; takes effect when automatic lookup is disabled or fails.
-           .buffer_pool_config = {
-               // ...
-      }
-  });
-```
-
-      4. Query all currently successfully registered RDMA global devices
-```cpp
-      // Get all devices
-      auto devices = coro_io::g_ib_device_manager();
-  for (auto &dev: devices.get_dev_list()) {
-    std::cout << "name:" << dev.first;
-    // dev.second is a global std::shared_ptr<ib_device_t>
-  }
-```
-
-## Calling Model
-
-Each `coro_rpc_client` is bound to a specific IO thread. By default, it selects a connection via round-robin from the global IO thread pool. Users can also manually bind it to a specific IO thread.
-
-```cpp
-auto executor=coro_io::get_global_executor();
-coro_rpc_client client(executor),client2(executor);
-  // Both clients are bound to the same IO thread.
-```
-
-Each time a coroutine-based IO task is initiated (such as `connect`, `call`, `send_request`), the client internally submits the IO event to the operating system. When the IO event is completed, the coroutine is then resumed on the bound IO thread to continue execution. For example, in the following code, the task switches to the IO thread for execution after calling connect.
-
-```cpp
-/*run in thread 1*/
-coro_rpc_client cli;
-co_await cli.connect("localhost:9001");
-/*run in thread 2*/
-do_something();
-```
-
-## Connection Pool and Load Balancing
-
-`coro_io` offers a connection pool `client_pool` and a load balancer `channel`. Users can manage `coro_rpc`/`coro_http` connections through the `client_pool`, and can use `channel` to achieve load balancing among multiple hosts. For more details, please refer to the documentation of `coro_io`.
-
-## Connection Reuse
-
-The `coro_rpc_client` can achieve connection reuse through the `send_request` function. This function is thread-safe, allowing multiple threads to call the `send_request` method on the same client concurrently. The return value of the function is `Lazy<Lazy<async_rpc_result<T>>>`. The first `co_await` waits for the request to be sent, and the second `co_await` waits for the rpc result to return.
-
-
-Connection reuse allows us to reduce the number of connections under high concurrency, eliminating the need to create new connections. It also improves the throughput of each connection.
-
-Here's a simple example code snippet:
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string_view echo(std::string_view);
-Lazy<void> example(coro_rpc_client& client) {
-  // send request to the server
-  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
-  // then wait server response
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  if (result) {
-    assert(result->result() == "Hello");
-  }
-  else {
-    // error handle
-    std::cout<<result.error().msg()<<std::endl;
-  }
-}
-```
-
-We can call send_request multiple times to implement connection reuse:
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string echo(std::string);
-Lazy<void> example(coro_rpc_client& client) {
-  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
-  // First, send 10 requests consecutively
-  for (int i=0;i<10;++i) {
-    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
-  }
-  // Next, wait for all the requests to return
-  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
-  for (int i=0;i<10;++i) {
-    assert(results[i]->result() == std::to_string(i));
-  }
-  co_return;
-}
-```
-
-When sending data using the connection pool, we can also reuse a connection. To do this, you need to add the `coro_io::client_reuse_hint` parameter to instruct the connection pool to enable connection reuse. For more details, see the connection pool documentation. (TODO)
-
-```cpp
-auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
-    conf.url, pool_conf);
-auto ret = co_await pool->send_request(
-    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
-             return client.send_request<echo>("hello");
-           });
-if (ret.has_value()) {
-  auto result = co_await std::move(ret.value());
-  if (result.has_value()) {
-        assert(result.value()=="hello"); 
-  }
-}
-```
-
-### Attachment
-
-When using the `send_request` method, since multiple requests might be sent simultaneously, we should not call the `set_req_attachment` method to send an attachment to the server, nor should we call the `get_resp_attachment` and `release_resp_attachment` methods to get the attachment returned by the server.
-
-Instead, we can set the attachment when sending a request by calling the `send_request_with_attachment` function. Additionally, we can retrieve the attachment by calling the `->get_attachment()` and `->release_buffer()` methods of `async_rpc_result`.
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-int add(int a, int b);
-Lazy<std::string> example(coro_rpc_client& client) {
-  auto handler = co_await client.send_request_with_attachment<add>("Hello", 1, 2);
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  assert(result->result() == 3);
-  assert(result->get_attachment() == "Hello");
-  co_return std::move(result->release_buffer().resp_attachment_buf_);
-}
-```
-
-
-### Execution order
-
-When the called rpc function is a coroutine rpc function or a callback rpc function, the rpc requests may not necessarily be executed in order. The server might execute multiple rpc requests simultaneously.
-For example, suppose there is the following code:
-
-```cpp
-using namespace async_simple::coro;
-Lazy<void> sleep(int seconds) {
-  co_await coro_io::sleep(1s * seconds);  // Yield the coroutine here
-  co_return;
-}
-```
-
-Server registration and startup:
-```cpp
-using namespace coro_rpc;
-void start() {
-  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
-  server.register_handler<sleep>();
-  server.start();
-}
-```
-
-The client consecutively calls the sleep function twice on the same connection, sleeping for 2 seconds the first time and 1 second the second time.
-```cpp
-using namespace async_simple::coro;
-using namespace coro_rpc;
-Lazy<void> call() {
-  coro_rpc_client cli,cli2;
-  co_await cli.connect("localhost:8801");
-  co_await cli2.connect("localhost:8801");
-  auto handler1 = co_await cli.send_request<sleep>(2);
-  auto handler2 = co_await cli.send_request<sleep>(1);
-  auto handler3 = co_await cli2.send_request<sleep>(0);
-  handler2.start([](auto&&){
-    std::cout<<"handler2 return"<<std::endl;
-  });
-  handler3.start([](auto&&){
-   d::cout<<"handler3 return"<<std::endl;
-  });
-  co_await handler1;
-  std::cout<<"handler1 return"<<std::endl;
-}
-```
-Under normal circumstances, handler3 will return first, followed by handler2, and finally handler1. Although the server only has one IO thread for executing rpc functions, the coroutine function will yield the coroutine when calling `coro_io::sleep`, thus ensuring that other connections will not be blocked.
-
-### Socket Delayed Sending
-
-When using connection reuse, you can try setting the option `enable_tcp_no_delay` to `false`. This allows the underlying implementation to batch multiple small requests together for sending, thereby increasing throughput, but it may lead to increased latency.
-
-## Thread-safe
-
-For multiple coro_rpc_client instances, they do not interfere with each other and can be safely called in different threads respectively.
-
-When calling a single `coro_rpc_client` simultaneously in multiple threads, it is necessary to note that only some member functions are thread-safe, including `send_request()`, `close()`, `connect()`, `get_executor()`, `get_pipeline_size()`, `get_client_id()`, `get_config()`, etc. If the user has not called the `connect()` function again with an endpoint or hostname, then the `get_port()` and `get_host()` functions are also thread-safe.
-
-It is important to note that the `call`, `get_resp_attachment`, `set_req_attachment`, `release_resp_attachment`, and `init_config` functions are not thread-safe and must not be called by multiple threads simultaneously. In this case, only `send_request` can be used for multiple threads to make concurrent requests over a single connection.
-
-# coro_rpc Performance Testing
-First, compile the coro_rpc benchmark and then execute the `bench` command-line tool. The command-line options are as follows:
-```
-options:
-  -u, --url                   URL (string [=0.0.0.0:9000])
-  -s, --send_data_len         Send data length (unsigned long [=8388608])
-  -c, --client_concurrency    Total number of clients (unsigned int [=0])
-  -m, --max_request_count     Max request count (unsigned long [=100000000])
-  -p, --port                  Server port (unsigned short [=9000])
-  -r, --resp_len              Response data length (unsigned long [=13])
-  -b, --buffer_size           Buffer size (unsigned int [=262144])
-  -o, --log_level             Log level. Severity::INFO=1 (default), WARN is 4, etc. (int [=1])
-  -i, --enable_ib             Enable ibverbs (RDMA) (bool [=1])
-  -d, --duration              Duration in seconds (unsigned int [=100000])
-  -?, --help                  Print this message
-```
-
-Server-side command:
-`./bench -p 9004 -r 13 -o 5`
-
-Meaning: Start the server, set the response data length to 13, and set the log level to error (the log levels correspond to those in easylog).
-
-Client-side command:
-`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
-
-Meaning: Start 100 clients for stress testing, sending 8MB of data per request, with the log level set to error, and a duration of 30 seconds.
-
-If user install ibverbs environment, ibverbs is enabled default. To test only TCP, add the flag `-i 0`.
-
-After the performance test completes, it will output QPS, throughput, and latency data. The test results will look similar to this:
-```
-# Benchmark result
-avg qps 2757 and throughput:185.04 Gb/s in duration 30
-# HELP Latency(us) of rpc call help
-# TYPE Latency(us) of rpc call summary
-rpc call latency(us){quantile="0.500000"} 3616.000000
-rpc call latency(us){quantile="0.900000"} 3712.000000
-rpc call latency(us){quantile="0.950000"} 3776.000000
-rpc call latency(us){quantile="0.990000"} 3872.000000
-rpc call latency(us)_sum 298707968.000000
-rpc call latency(us)_count 82761
+# Introduction to coro_rpc Client
+
+## Base Usage
+
+class `coro_rpc::coro_rpc_client` is the client side of coro_rpc, allowing users to send RPC requests to the server. 
+
+Below, we will demonstrate the basic usage of rpc_client.
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+int add(int a,int b);
+Lazy<void> example() {
+  coro_rpc_client client;
+  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
+  if (ec) { /*check if connection error*/
+    std::cout<<ec.message()<<std::endl;
+    co_return;
+  }
+  rpc_result result = co_await client.call<add>(1,2);
+  /*rpc_result is type of expected<T,rpc_error>, which T is rpc return type*/
+  if (!result.has_value()) {
+    /*call result.error() to get rpc error message*/
+    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
+    co_return;
+  }
+  assert(result.value()==3); /*call result.value() to  get rpc return type*/
+}
+```
+
+You can use the `set_req_attachment` function to set the attachment for the current request. This is a piece of binary data that will be sent directly to the client without serialization. Similarly, you can also use `get_resp_attachment()` and `release_resp_attachment()` to retrieve the attachment returned by the RPC request.
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+void attachment_echo() {
+  auto ctx=coro_rpc::get_context();
+  ctx->set_resp_attachment(ctx->get_req_attachment());
+}
+Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
+  client.set_req_attachment(attachment);
+  rpc_result result = co_await client.call<attachment_echo>();
+  if (result.has_value()) {
+    assert(result.get_resp_attachment()==attachment);
+    co_return std::move(result.release_resp_attachment());
+  }
+  co_return "";
+}
+```
+
+By default, the RPC client will wait for 5 seconds after sending a request/establishing a connection. If no response is received after 5 seconds, it will return a timeout error. Users can also customize the wait duration by calling the `call_for` function.
+
+```cpp
+client.connect("127.0.0.1:9001", std::chrono::seconds{10});
+auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
+assert(result.value() == 3);
+```
+
+The duration can be any `std::chrono::duration` type, common examples include `std::chrono::seconds` and `std::chrono::milliseconds`. Notably, if the duration is set to zero, it indicates that the function call will never time out.
+
+## SSL support
+
+coro_rpc supports using OpenSSL to encrypt connections. After installing OpenSSL and importing yalantinglibs into your project with CMake's `find_package` or `fetch_content`, you can enable SSL support by setting the CMake option YLT_ENABLE_SSL=ON. Alternatively, you might manually add the YLT_ENABLE_SSL macro and manually link to OpenSSL.
+
+Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It’s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
+
+For one -way SSL authentication(server authentication only),you can use the `init_ssl` function before establishing a connection:The first parameter is the base path where the SSL certificates are located, and the second parameter is the CA certificate filename for verifying the server.
+
+Server-side configuration:
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "";  // Empty for one-way authentication
+ssl_conf.enable_client_verify = false;  // Disable client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+Mutual SSL Authentication For mutual SSL authentication(both client and server authentication),the client needs to provide its own certificate :
+
+```cpp
+    // Client-side mutual authentication
+    client.init_ssl("./",  // Base path
+                    "ca.crt",  // CA certificate for server verification
+                    "client.crt",  // Client certificate
+                    "client.key",  // Client private key
+                    "127.0.0.1"  // Server hostname for SNI
+    );
+```
+
+Server-side configuration for mutual authentication:
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "ca.crt";  // CA certificate for verifying clients
+ssl_conf.enable_client_verify = true;  // Enable mandatory client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+**Important Notes**:
+- The `enable_client_verify` flag enables mandatory client certificate verification
+- When mutual authentication is enabled, clients must provide a valid certificate signed by the CA specified in `ca_cert_file`
+- The hostname parameter must match the Common Name (CN) in the server certificate
+
+We also support NTLS if you enable it by CMAKE OPTION `YLT_ENABLE_NTLS`.
+
+## Conversion and compile-time checking of RPC parameters
+
+coro_rpc will perform compile-time checks on the validity of arguments during invocation. For example, for the following rpc function:
+
+```cpp
+inline std::string echo(std::string str) { return str; }
+```
+
+Next, when the current client invokes the rpc function:
+
+```cpp
+client.call<echo>(42); // Parameter does not match, compilation error
+client.call<echo>(); // Missing parameter, compilation error
+client.call<echo>("", 0); // Extra parameters, compilation error
+client.call<echo>("hello, coro_rpc"); // The string literal can be converted to std::string, compilation succeeds
+```
+
+## Connection Options
+
+The `coro_rpc_client` provides an `init_config` function to configure connection options. The code below lists all configurable options, which are optional with default values.
+
+```cpp
+using namespace coro_rpc;
+using namespace std::chrono;
+void set_config(coro_rpc_client& client) {
+  uint64_t client_id;
+  std::chrono::milliseconds connect_timeout_duration;
+  std::chrono::milliseconds request_timeout_duration;
+  std::string host;
+  std::string port;
+  std::string local_ip;
+  client.init_config(config{
+    .connect_timeout_duration = 5s, // Connection timeout duration
+    .request_timeout_duration = 5s, // Request timeout duration
+    .host = "localhost", // Server hostname
+    .port = "9001", // Server port
+    .local_ip = "", // Local IP address used to specify the local communication interface
+    .socket_config=std::variant<tcp_config,
+                 tcp_with_ssl_config,
+                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // Specify transport protocol and its configuration. Supported protocols: TCP, SSL over TCP, RDMA
+  });
+}
+```
+
+### RDMA Socket Configuration
+
+The configuration for IBVerbs socket protocol is shown below:
+
+```cpp
+struct ib_socket_t::config_t {
+  uint32_t cq_size = 128; // Maximum length of event notification queue
+  uint32_t recv_buffer_cnt = 8;                 // Number of buffers pre-submitted to receive queue. Each buffer defaults to 256KB, so a RDMA connection occupies 8MB memory immediately after establishment. More pending receive data will result in more buffers in the queue, up to max_recv_wr*buffer_size (where buffer_size is configured in buffer_pool). If upper layer doesn't consume data, sender will receive RNR (Receiver Not Ready) errors and retry continuously.
+  uint32_t send_buffer_cnt = 4;                 // default send buffer queue max size,
+  ibv_qp_type qp_type = IBV_QPT_RC;             // Default QP type
+  ibv_qp_cap cap = {.max_send_wr = 32,           // Maximum send queue length
+                    .max_recv_wr = 32,          // Maximum receive queue length
+                    .max_send_sge = 3,          // Maximum send scatter/gather elements. Only 1 needed without inline data. Use 3 segments when using inline data (default supports 3 scattered addresses)
+                    .max_recv_sge = 1,          // Maximum receive scatter/gather elements. 1 suffices with current buffer configuration
+                    .max_inline_data = 256};    // If packet size < inline data threshold and NIC supports it, small packets bypass buffer copy and go directly to NIC
+  std::shared_ptr<coro_io::ib_device_t> device; // Underlying IB device for RPC. Defaults to first device in list
+};
+```
+
+Simple RDMA activation examples:
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv(); // Use default configuration
+  cli.init_ibv({.recv_buffer_cnt=8}); // Use custom configuration
+```
+
+RDMA activation through config:
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
+```
+
+#### RDMA Device Configuration
+
+The `ib_device_t` manages the connection context and buffers required during the ibverbs transmission process. By default, it uses the global device `coro_io::get_global_ib_device()`, but users can also specify their own device.
+
+By modifying the configuration of `ib_device_t`, users can assign different network interfaces to RPC connections and use separate buffers.
+
+1. Modify the default device configuration
+```cpp
+  // The configuration only takes effect on the first invocation
+  coro_io::get_global_ib_device({ 
+    .buffer_pool_config = {
+      .buffer_size = 256 * 1024,  // Buffer size
+      .max_memory_usage = 4 * 1024 * 1024, // Max memory usage (allocation fails beyond this limit)
+      .memory_usage_recorder = nullptr; // nullopt means that memory usage across different devices will be counted together. If you want the memory pool to have independent memory usage tracking, you should assign a non-null std::shared_ptr<std::atomic<std::size_t>> as the recorder.
+      .idle_timeout = 5s // Buffers unused for this duration will be reclaimed
+  }
+  });
+  // ...
+```
+
+      2. Specify the RDMA NIC to use when initializing the connection
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
+  });
+```
+
+      3. Create and use your own `ib_device_t`
+```cpp
+  auto dev = coro_io::ib_device_t::create({
+      .dev_name = "",  // If dev_name is empty, the first device in the device list will be used.
+      .port = 1,       // Manually specify the NIC port number.
+           .use_best_gid_index = true,  // Automatically find the best GID index for this device.
+      .gid_index = 0,   // Manually specify the GID index; takes effect when automatic lookup is disabled or fails.
+           .buffer_pool_config = {
+               // ...
+      }
+  });
+```
+
+      4. Query all currently successfully registered RDMA global devices
+```cpp
+      // Get all devices
+      auto devices = coro_io::g_ib_device_manager();
+  for (auto &dev: devices.get_dev_list()) {
+    std::cout << "name:" << dev.first;
+    // dev.second is a global std::shared_ptr<ib_device_t>
+  }
+```
+
+## Calling Model
+
+Each `coro_rpc_client` is bound to a specific IO thread. By default, it selects a connection via round-robin from the global IO thread pool. Users can also manually bind it to a specific IO thread.
+
+```cpp
+auto executor=coro_io::get_global_executor();
+coro_rpc_client client(executor),client2(executor);
+  // Both clients are bound to the same IO thread.
+```
+
+Each time a coroutine-based IO task is initiated (such as `connect`, `call`, `send_request`), the client internally submits the IO event to the operating system. When the IO event is completed, the coroutine is then resumed on the bound IO thread to continue execution. For example, in the following code, the task switches to the IO thread for execution after calling connect.
+
+```cpp
+/*run in thread 1*/
+coro_rpc_client cli;
+co_await cli.connect("localhost:9001");
+/*run in thread 2*/
+do_something();
+```
+
+## Connection Pool and Load Balancing
+
+`coro_io` offers a connection pool `client_pool` and a load balancer `channel`. Users can manage `coro_rpc`/`coro_http` connections through the `client_pool`, and can use `channel` to achieve load balancing among multiple hosts. For more details, please refer to the documentation of `coro_io`.
+
+## Connection Reuse
+
+The `coro_rpc_client` can achieve connection reuse through the `send_request` function. This function is thread-safe, allowing multiple threads to call the `send_request` method on the same client concurrently. The return value of the function is `Lazy<Lazy<async_rpc_result<T>>>`. The first `co_await` waits for the request to be sent, and the second `co_await` waits for the rpc result to return.
+
+
+Connection reuse allows us to reduce the number of connections under high concurrency, eliminating the need to create new connections. It also improves the throughput of each connection.
+
+Here's a simple example code snippet:
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string_view echo(std::string_view);
+Lazy<void> example(coro_rpc_client& client) {
+  // send request to the server
+  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
+  // then wait server response
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  if (result) {
+    assert(result->result() == "Hello");
+  }
+  else {
+    // error handle
+    std::cout<<result.error().msg()<<std::endl;
+  }
+}
+```
+
+We can call send_request multiple times to implement connection reuse:
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string echo(std::string);
+Lazy<void> example(coro_rpc_client& client) {
+  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
+  // First, send 10 requests consecutively
+  for (int i=0;i<10;++i) {
+    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
+  }
+  // Next, wait for all the requests to return
+  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
+  for (int i=0;i<10;++i) {
+    assert(results[i]->result() == std::to_string(i));
+  }
+  co_return;
+}
+```
+
+When sending data using the connection pool, we can also reuse a connection. To do this, you need to add the `coro_io::client_reuse_hint` parameter to instruct the connection pool to enable connection reuse. For more details, see the connection pool documentation. (TODO)
+
+```cpp
+auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
+    conf.url, pool_conf);
+auto ret = co_await pool->send_request(
+    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
+             return client.send_request<echo>("hello");
+           });
+if (ret.has_value()) {
+  auto result = co_await std::move(ret.value());
+  if (result.has_value()) {
+        assert(result.value()=="hello"); 
+  }
+}
+```
+
+### Attachment
+
+When using the `send_request` method, since multiple requests might be sent simultaneously, we should not call the `set_req_attachment` method to send an attachment to the server, nor should we call the `get_resp_attachment` and `release_resp_attachment` methods to get the attachment returned by the server.
+
+Instead, we can set the attachment when sending a request by calling the `send_request_with_attachment` function. Additionally, we can retrieve the attachment by calling the `->get_attachment()` and `->release_buffer()` methods of `async_rpc_result`.
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+int add(int a, int b);
+Lazy<std::string> example(coro_rpc_client& client) {
+  auto handler = co_await client.send_request_with_attachment<add>("Hello", 1, 2);
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  assert(result->result() == 3);
+  assert(result->get_attachment() == "Hello");
+  co_return std::move(result->release_buffer().resp_attachment_buf_);
+}
+```
+
+
+### Execution order
+
+When the called rpc function is a coroutine rpc function or a callback rpc function, the rpc requests may not necessarily be executed in order. The server might execute multiple rpc requests simultaneously.
+For example, suppose there is the following code:
+
+```cpp
+using namespace async_simple::coro;
+Lazy<void> sleep(int seconds) {
+  co_await coro_io::sleep(1s * seconds);  // Yield the coroutine here
+  co_return;
+}
+```
+
+Server registration and startup:
+```cpp
+using namespace coro_rpc;
+void start() {
+  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
+  server.register_handler<sleep>();
+  server.start();
+}
+```
+
+The client consecutively calls the sleep function twice on the same connection, sleeping for 2 seconds the first time and 1 second the second time.
+```cpp
+using namespace async_simple::coro;
+using namespace coro_rpc;
+Lazy<void> call() {
+  coro_rpc_client cli,cli2;
+  co_await cli.connect("localhost:8801");
+  co_await cli2.connect("localhost:8801");
+  auto handler1 = co_await cli.send_request<sleep>(2);
+  auto handler2 = co_await cli.send_request<sleep>(1);
+  auto handler3 = co_await cli2.send_request<sleep>(0);
+  handler2.start([](auto&&){
+    std::cout<<"handler2 return"<<std::endl;
+  });
+  handler3.start([](auto&&){
+   d::cout<<"handler3 return"<<std::endl;
+  });
+  co_await handler1;
+  std::cout<<"handler1 return"<<std::endl;
+}
+```
+Under normal circumstances, handler3 will return first, followed by handler2, and finally handler1. Although the server only has one IO thread for executing rpc functions, the coroutine function will yield the coroutine when calling `coro_io::sleep`, thus ensuring that other connections will not be blocked.
+
+### Socket Delayed Sending
+
+When using connection reuse, you can try setting the option `enable_tcp_no_delay` to `false`. This allows the underlying implementation to batch multiple small requests together for sending, thereby increasing throughput, but it may lead to increased latency.
+
+## Thread-safe
+
+For multiple coro_rpc_client instances, they do not interfere with each other and can be safely called in different threads respectively.
+
+When calling a single `coro_rpc_client` simultaneously in multiple threads, it is necessary to note that only some member functions are thread-safe, including `send_request()`, `close()`, `connect()`, `get_executor()`, `get_pipeline_size()`, `get_client_id()`, `get_config()`, etc. If the user has not called the `connect()` function again with an endpoint or hostname, then the `get_port()` and `get_host()` functions are also thread-safe.
+
+It is important to note that the `call`, `get_resp_attachment`, `set_req_attachment`, `release_resp_attachment`, and `init_config` functions are not thread-safe and must not be called by multiple threads simultaneously. In this case, only `send_request` can be used for multiple threads to make concurrent requests over a single connection.
+
+# coro_rpc Performance Testing
+First, compile the coro_rpc benchmark and then execute the `bench` command-line tool. The command-line options are as follows:
+```
+options:
+  -u, --url                   URL (string [=0.0.0.0:9000])
+  -s, --send_data_len         Send data length (unsigned long [=8388608])
+  -c, --client_concurrency    Total number of clients (unsigned int [=0])
+  -m, --max_request_count     Max request count (unsigned long [=100000000])
+  -p, --port                  Server port (unsigned short [=9000])
+  -r, --resp_len              Response data length (unsigned long [=13])
+  -b, --buffer_size           Buffer size (unsigned int [=262144])
+  -o, --log_level             Log level. Severity::INFO=1 (default), WARN is 4, etc. (int [=1])
+  -i, --enable_ib             Enable ibverbs (RDMA) (bool [=1])
+  -d, --duration              Duration in seconds (unsigned int [=100000])
+  -?, --help                  Print this message
+```
+
+Server-side command:
+`./bench -p 9004 -r 13 -o 5`
+
+Meaning: Start the server, set the response data length to 13, and set the log level to error (the log levels correspond to those in easylog).
+
+Client-side command:
+`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
+
+Meaning: Start 100 clients for stress testing, sending 8MB of data per request, with the log level set to error, and a duration of 30 seconds.
+
+If user install ibverbs environment, ibverbs is enabled default. To test only TCP, add the flag `-i 0`.
+
+After the performance test completes, it will output QPS, throughput, and latency data. The test results will look similar to this:
+```
+# Benchmark result
+avg qps 2757 and throughput:185.04 Gb/s in duration 30
+# HELP Latency(us) of rpc call help
+# TYPE Latency(us) of rpc call summary
+rpc call latency(us){quantile="0.500000"} 3616.000000
+rpc call latency(us){quantile="0.900000"} 3712.000000
+rpc call latency(us){quantile="0.950000"} 3776.000000
+rpc call latency(us){quantile="0.990000"} 3872.000000
+rpc call latency(us)_sum 298707968.000000
+rpc call latency(us)_count 82761
 ```

-# coro_rpc客户端介绍
-
-## 基本使用
-
-类`coro_rpc::coro_rpc_client`是coro_rpc的客户端，用户可以通过它向服务器发送rpc请求。
-
-下面我们展示rpc_client的基本使用方法。
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-int add(int a,int b);
-Lazy<void> example() {
-  coro_rpc_client client;
-  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
-  if (ec) { /*判断连接是否出错*/
-    std::cout<<ec.message()<<std::endl;
-    co_return;
-  }
-  rpc_result result = co_await client.call<add>(1,2);
-  /*rpc_result是一个expected<T,rpc_error>类型，其中T为rpc返回值*/
-  if (!result.has_value()) {
-    /*调用result.error()获取rpc错误信息*/
-    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
-    co_return;
-  }
-  assert(result.value()==3); /*调用result.value()获取rpc返回值*/
-}
-```
-
-我们可以通过`set_req_attachment`函数设置本次请求的attachment，这是一段不会经过序列化直接发送给客户端的二进制数据。同样的，我们也可以使用`get_resp_attachment()`和`release_resp_attachment()`来获取rpc请求返回的attachment。
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-void attachment_echo() {
-  auto ctx=coro_rpc::get_context();
-  ctx->set_resp_attachment(ctx->get_req_attachment());
-}
-Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
-  client.set_req_attachment(attachment);
-  rpc_result result = co_await client.call<attachment_echo>();
-  if (result.has_value()) {
-    assert(result.get_resp_attachment()==attachment);
-    co_return std::move(result.release_resp_attachment());
-  }
-  co_return "";
-}
-```
-
-默认情况下，rpc客户端发送请求/建立连接后会等待5秒，如果5秒后仍未收到响应，则会返回超时错误。
-用户也可以通过调用`call_for`函数自定义等待的时长。
-
-```cpp
-client.connect("127.0.0.1:9001", std::chrono::seconds{10});
-auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
-assert(result.value() == 3);
-```
-
-时长可以是任一的`std::chrono::duration`类型，常见的如`std::chrono::seconds`,`std::chrono::millseconds`。
-特别的，如果时长为0，代表该函数调用永远也不会超时。
-
-## SSL支持
-
-coro_rpc支持使用openssl对连接进行加密。在安装openssl并使用cmake find_package/fetch_content 将yalantinglibs导入到你的工程后，可以打开cmake选项`YLT_ENABLE_SSL=ON`启用ssl支持。或者，你也可以手动添加宏`YLT_ENABLE_SSL`并手动链接openssl。
-
-当启用ssl支持后，用户可以调用`init_ssl`函数，然后再连接到服务器。这会使得客户端与服务器之间建立加密的链接。需要注意的是，coro_rpc服务端在编译时也必须启用ssl支持，并且在启动服务器之前也需要调用`init_ssl`方法来启用SSL支持。
-
-```cpp
-client.init_ssl("./","server.crt");
-```
-
-第一个字符串代表SSL证书所在的基本路径，第二个字符串代表SSL证书相对于基本路径的相对路径。
-
-当建立连接时，客户端会使用该证书校验服务端发来的证书，以避免中间人攻击。因此，客户端必须持有服务端使用的证书或其根证书。
-
-我们同样支持国密NTLS。你需要开启CMAKE选项`YLT_ENABLE_NTLS`。
-
-## RPC参数的转换与编译期检查
-
-coro_rpc会在调用的时候对参数的合法性做编译期检查，比如，对于如下rpc函数：
-
-```cpp
-inline std::string echo(std::string str) { return str; }
-```
-
-接下来，当前client调用rpc函数时：
-
-```cpp
-client.call<echo>(42);// The argument does not match, a compilation error occurs.
-client.call<echo>();// Missing argument, compilation error occurs.
-client.call<echo>("", 0);// There are too many arguments, a compilation error occurs.
-client.call<echo>("hello, coro_rpc");// The string literal can be converted to std::string, compilation succeeds.
-```
-
-## 连接选项
-
-coro_rpc_client提供了`init_config`函数，用于配置连接选项。下面这份代码列出了可配置的选项。这些选项默认均可以不填写。
-
-```cpp
-using namespace coro_rpc;
-using namespace std::chrono;
-void set_config(coro_rpc_client& client) {
-  uint64_t client_id;
-  std::chrono::milliseconds connect_timeout_duration;
-  std::chrono::milliseconds request_timeout_duration;
-  std::string host;
-  std::string port;
-  std::string local_ip;
-  client.init_config(config{
-    .connect_timeout_duration = 5s, // 连接的超时时间
-    .request_timeout_duration = 5s, // 请求超时时间
-    .host = "localhost", // 服务器域名
-    .port = "9001", // 服务器端口
-    .local_ip = "", // 本地ip，用于指定本地通信的ip地址。
-    .socket_config=std::variant<tcp_config,
-                 tcp_with_ssl_config,
-                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // 指定底层的协议及其底层配置，目前支持tcp, ssl over tcp, rdma三种协议。
-  });
-}
-```
-
-
-### rdma配置
-
-ibverbs协议的配置如下：
-```cpp
-struct ib_socket_t::config_t {
-  uint32_t cq_size = 128; // 事件通知队列的最大长度
-  uint32_t recv_buffer_cnt = 8;                 // 默认提交到接受队列的缓冲数目，一个缓冲区默认256KB。积压的接收数据越多，队列中的缓冲区也会越多，最多可以缓冲max_recv_wr*buffer_size这么多的数据(buffer_size为buffer_pool配置的缓冲区大小），此后如果上层仍不消费数据，则发送端会收到rnr错误，不断重试并等待对端消费。
-  uint32_t send_buffer_cnt = 4;                 // 默认的发送缓冲区队列长度上限。代表最多积压的发送缓冲区数目。
-  ibv_qp_type qp_type = IBV_QPT_RC;             // 默认的qp类型。
-  ibv_qp_cap cap = {.max_send_wr = 32,           // 发送队列的最大长度。
-                    .max_recv_wr = 32,          // 接受队列的最大长度
-                    .max_send_sge = 3,          // 发送的最大地址分段数，在不启用inline data时只需要1个。使用inline data时数据可能不经过拷贝直接从原始分段地址发送，因此设置为3段（默认支持3段分散地址）。
-                    .max_recv_sge = 1,          // 接受的最大地址分段数，目前的缓冲区配置下只需要1个即可。
-                    .max_inline_data = 256};    // 如果发送的数据包小于inline data，且底层网卡支持该设置，则小数据包不会被拷贝到缓冲中，而是直接交给网卡发送。
-  std::shared_ptr<coro_io::ib_device_t> device; // rpc使用的底层ib网卡。默认选择设备列表第一个网卡。
-};
-```
-
-可以通过下面的代码简单的启用rdma：
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv(); //使用默认配置
-  cli.init_ibv(ib_socket_t::config_t{}); //使用用户指定的配置
-```
-
-也可以在配置中启用rdma：
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
-```
-
-
-#### ib_device_t
-
-`ib_device_t`管理了ibverbs传输过程中需要使用到的连接上下文和缓冲区。默认使用全局设备`coro_io::get_global_ib_device()`，用户也可以指定使用自己的设备。
-
-通过修改ib_device_t的配置，可以给rpc连接配置不同的网卡，使用独立的缓冲区。
-
-1. 修改默认的设备配置
-```cpp
-  // 配置只有在第一次调用时才会生效
-  coro_io::get_global_ib_device({ 
-    .buffer_pool_config = {
-      .buffer_size = 256 * 1024,  // 缓冲区大小
-      .max_memory_usage = 4 * 1024 * 1024, // 最大内存使用量（超过此限制将分配失败）
-      .memory_usage_recorder = nullptr; // nullopt 表示不同设备的内存占用会被一起统计，如果想要让内存池具有独立的内存占用记录，请分配一个非空的std::shared_ptr<std::atomic<std::size_t>>作为记录
-      .idle_timeout = 5s // 空闲时间超过这个时长的缓冲区将被回收
-    }
-  }); 
-  // ...
-```
-
-2. 初始化连接时，指定需要使用的 RDMA 网卡
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
-  });
-```
-
-3. 创建并使用自己的 `ib_device_t`
-```cpp
-  auto dev = coro_io::ib_device_t::create({
-    .dev_name = "",  // 如果 dev_name 为 空，则会使用设备列表中的第一个设备
-    .port = 1, // 手动指定网卡port
-    .use_best_gid_index = true, // 自动查找该设备最佳的gid_index
-    .gid_index = 0, // 手动指定gid_index，当关闭自动查找或自动查找失败时生效
-    .buffer_pool_config = {
-      // ...
-    },
-  });
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = dev
-  });
-```
-
-4. 查询当前所有成功注册的全局 RDMA 设备
-```cpp
-  // 获取所有设备
-  auto devices = coro_io::g_ib_device_manager();
-  for (auto &dev: devices.get_dev_list()) {
-    std::cout<<"name:"<<dev.first;
-    // dev.second 是一个全局的 std::shared_ptr<ib_device_t>
-  }
-```
-
-## 调用模型
-
-每一个`coro_rpc_client`都会绑定到某个IO线程上，默认通过轮转法从全局IO线程池中选择一个连接，用户也可以手动绑定到特定的IO线程上。
-
-```cpp
-auto executor=coro_io::get_global_executor();
-coro_rpc_client client(executor),client2(executor);
-// 两个客户端都被绑定到同一个io线程上
-```
-
-每次发起一个基于协程的IO任务（如`connect`,`call`,`send_request`），客户端内部会将IO事件提交给操作系统，当IO事件完成后，再将协程恢复到绑定的IO线程上继续执行。
-
-例如以下代码，调用connect之后任务将切换到IO线程执行。
-
-```cpp
-/*run in thread 1*/
-coro_rpc_client cli;
-co_await cli.connect("localhost:9001");
-/*run in thread 2*/
-do_something();
-```
-
-## 连接池与负载均衡
-
-`coro_io`提供了连接池`client_pool`与负载均衡器`channel`。用户可以通过连接池`client_pool`来管理`coro_rpc`/`coro_http`连接，可以使用`channel`实现多个host之间的负载均衡。具体请见`coro_io`的文档。
-
-## 连接复用
-
-`coro_rpc_client` 可以通过 `send_request`函数实现连接复用。该函数是线程安全的，允许多个线程同时调用同一个client的 `send_request`方法。该函数返回值为`Lazy<Lazy<async_rpc_result<T>>>`.
-
-
-连接复用允许我们在高并发下减少连接的个数，无需创建新的连接。同时也能提高每个连接的吞吐量。
-
-下面是一段简单的示例代码：
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string_view echo(std::string_view);
-Lazy<void> example(coro_rpc_client& client) {
-  //向服务器发送请求
-  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  if (result) {
-    assert(result->result() == "Hello");
-  }
-  else {
-    // error handle
-    std::cout<<result.error().msg()<<std::endl;
-  }
-}
-```
-
-我们可以多次调用send_request实现连接复用：
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string echo(std::string);
-Lazy<void> example(coro_rpc_client& client) {
-  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
-  // 准备发送10个请求
-  for (int i=0;i<10;++i) {
-    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
-  }
-  //接下来等待所有的请求返回
-  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
-  for (int i=0;i<10;++i) {
-    assert(results[i]->result() == std::to_string(i));
-  }
-  co_return;
-}
-```
-
-在使用连接池发送数据时，我们也可以复用连接，此时需要在添加`coro_io_client_reuse_hint`参数，提示连接池启用连接复用。详见连接池文档。（TODO）
-
-```cpp
-auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
-    conf.url, pool_conf);
-auto ret = co_await pool->send_request(
-    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
-        return client.send_request<echo>("hello");
-    });
-if (ret.has_value()) {
-    auto result = co_await std::move(ret.value());
-    if (result.has_value()) {
-        assert(result.value()=="hello"); 
-    }
-}
-```
-
-
-### Attachment
-
-使用`send_request`方法时，由于可能同时发送多个请求，因此我们不能调用`set_req_attachment`方法向服务器发送attachment，同样也不能调用`get_resp_attachment`和`release_resp_attachment`方法来获取服务器返回的attachment。
-
-我们可以通过调用`send_request_with_attachment`函数，在发送请求时设置attachment。我们也可以通过调用async_rpc_result的`->get_attachment()`方法和`->release_buffer()`方法来获取attachment。
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-int add(int a, int b);
-Lazy<std::string> example(coro_rpc_client& client) {
-  async_rpc_result<std::string_view> result = co_await co_await client.send_request_with_attachment<add>("Hello", 1, 2);
-  assert(result->result() == 3);
-  assert(result->get_attachment() == "Hello");
-  co_return std::move(result->release_buffer().resp_attachment_buf_);
-}
-```
-
-
-### 执行顺序
-
-当调用的rpc函数是协程rpc函数或回调rpc函数时，rpc请求不一定会按顺序执行，服务端可能会同时执行多个rpc请求。
-
-例如，假如有以下代码：
-
-```cpp
-using namespace async_simple::coro;
-Lazy<void> sleep(int seconds) {
-  co_await coro_io::sleep(1s * seconds);  // 在此处让出协程
-  co_return;
-}
-```
-
-服务器注册并启动：
-```cpp
-using namespace coro_rpc;
-void start() {
-  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
-  server.register_handler<sleep>();
-  server.start();
-}
-```
-
-客户端连续在同一个连接上调用两次sleep函数，第一次sleep2秒，第二次sleep1秒。
-```cpp
-using namespace async_simple::coro;
-using namespace coro_rpc;
-Lazy<void> call() {
-  coro_rpc_client cli,cli2;
-  co_await cli.connect("localhost:8801");
-  co_await cli2.connect("localhost:8801");
-  auto handler1 = co_await cli.send_request<sleep>(2);
-  auto handler2 = co_await cli.send_request<sleep>(1);
-  auto handler3 = co_await cli2.send_request<sleep>(0);
-  handler2.start([](auto&&){
-    std::cout<<"handler2 return"<<std::endl;
-  });
-  handler3.start([](auto&&){
-   d::cout<<"handler3 return"<<std::endl;
-  });
-  co_await handler1;
-  std::cout<<"handler1 return"<<std::endl;
-}
-```
-正常情况下handler3会先返回，随后是handler2，最后是handler1。尽管服务器只有一个IO线程用于执行rpc函数，但协程函数会在调用`coro_io::sleep`时让出该协程，从而保证其他连接不会被阻塞。
-
-### socket延迟发送
-
-当使用连接复用时，可以尝试将选项中的`enable_tcp_no_delay`设为`false`,这允许底层实现将多个小请求打包后一起发送，从而提高吞吐量，但是可能会导致延迟上升。
-
-## 线程安全
-
-对于多个coro_rpc_client实例，它们之间互不干扰，可以分别在不同的线程中安全的调用。
-
-单个coro_rpc_client在多个线程同时调用时需要注意，只有部分成员函数是线程安全的，包括`send_request()`,`close()`,`connect()`,`get_executor()`,`get_pipeline_size()`,`get_client_id()`,`get_config()`等。如果用户没有重新调用connect()函数并传入endpoint或hostname，那么`get_port()`,`get_host()`函数也是线程安全的。
-
-需要注意，`call`,`get_resp_attachment`,`set_req_attachment`,`release_resp_attachment`和`init_config`函数均不是线程安全的，禁止多个线程同时调用。此时只能使用`send_request`实现多个线程并发请求同一个连接。
-
-# coro_rpc 性能测试
-先编译coro_rpc 的bench再执行bench命令行，命令行详情：
-```
-options:
-  -u, --url                   url (string [=0.0.0.0:9000])
-  -s, --send_data_len         send data length (unsigned long [=8388608])
-  -c, --client_concurrency    total number of http clients (unsigned int [=0])
-  -m, --max_request_count     max request count (unsigned long [=100000000])
-  -p, --port                  server port (unsigned short [=9000])
-  -r, --resp_len              response data length (unsigned long [=13])
-  -b, --buffer_size           buffer size (unsigned int [=262144])
-  -o, --log_level             Severity::INFO 1 as default, WARN is 4 (int [=1])
-  -i, --enable_ib             enable ib (bool [=1])
-  -d, --duration              duration seconds (unsigned int [=100000])
-  -?, --help                  print this message
-```
-
-server侧命令行：
-`./bench -p 9004 -r 13 -o 5`
-
-含义：启动服务端，response的数据长度为13，日志级别为error(日志级别和easylog的日志级别对应)。
-
-client测命令行：
-`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
-
-含义：启动100个client去压测，每次请求发送8MB数据，日志级别为error，持续时间30秒。
-
-如果安装了ibverbs环境，则默认会启用ibverbs，如果希望只测试tcp则添加`-i 0`
-
-性能测试完成之后将输出qps，吞吐和latency数据，测试结果类似于：
-```
-# Benchmark result
-avg qps 2757 and throughput:185.04 Gb/s in duration 30
-# HELP Latency(us) of rpc call help
-# TYPE Latency(us) of rpc call summary
-rpc call latency(us){quantile="0.500000"} 3616.000000
-rpc call latency(us){quantile="0.900000"} 3712.000000
-rpc call latency(us){quantile="0.950000"} 3776.000000
-rpc call latency(us){quantile="0.990000"} 3872.000000
-rpc call latency(us)_sum 298707968.000000
-rpc call latency(us)_count 82761

+  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
+  if (ec) { /*判断连接是否出错*/
+    std::cout<<ec.message()<<std::endl;
+    co_return;
+  }
+  rpc_result result = co_await client.call<add>(1,2);
+  /*rpc_result是一个expected<T,rpc_error>类型，其中T为rpc返回值*/
+  if (!result.has_value()) {
+    /*调用result.error()获取rpc错误信息*/
+    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
+    co_return;
+  }
+  assert(result.value()==3); /*调用result.value()获取rpc返回值*/
+}
+```
+
+我们可以通过`set_req_attachment`函数设置本次请求的attachment，这是一段不会经过序列化直接发送给客户端的二进制数据。同样的，我们也可以使用`get_resp_attachment()`和`release_resp_attachment()`来获取rpc请求返回的attachment。
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+void attachment_echo() {
+  auto ctx=coro_rpc::get_context();
+  ctx->set_resp_attachment(ctx->get_req_attachment());
+}
+Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
+  client.set_req_attachment(attachment);
+  rpc_result result = co_await client.call<attachment_echo>();
+  if (result.has_value()) {
+    assert(result.get_resp_attachment()==attachment);
+    co_return std::move(result.release_resp_attachment());
+  }
+  co_return "";
+}
+```
+
+默认情况下，rpc客户端发送请求/建立连接后会等待5秒，如果5秒后仍未收到响应，则会返回超时错误。
+用户也可以通过调用`call_for`函数自定义等待的时长。
+
+```cpp
+client.connect("127.0.0.1:9001", std::chrono::seconds{10});
+auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
+assert(result.value() == 3);
+```
+
+时长可以是任一的`std::chrono::duration`类型，常见的如`std::chrono::seconds`,`std::chrono::millseconds`。
+特别的，如果时长为0，代表该函数调用永远也不会超时。
+
+## SSL支持
+
+coro_rpc支持使用openssl对连接进行加密。在安装openssl并使用cmake find_package/fetch_content 将yalantinglibs导入到你的工程后，可以打开cmake选项`YLT_ENABLE_SSL=ON`启用ssl支持。或者，你也可以手动添加宏`YLT_ENABLE_SSL`并手动链接openssl。
+
+当启用ssl支持后，用户可以调用`init_ssl`函数，然后再连接到服务器。这会使得客户端与服务器之间建立加密的链接。需要注意的是，coro_rpc服务端在编译时也必须启用ssl支持，并且在启动服务器之前也需要调用`init_ssl`方法来启用SSL支持。
+
+### 单向SSL认证
+
+单向SSL认证只验证服务器身份，客户端使用CA证书验证服务器：
+
+服务端配置：
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "";  // 单向认证为空
+ssl_conf.enable_client_verify = false;  // 不验证客户端证书
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+### 双向SSL认证（Mutual Authentication）
+
+双向SSL认证同时验证客户端和服务器身份，客户端需要提供自己的证书：
+
+客户端配置：
+
+```cpp
+    // 客户端双向认证
+    client.init_ssl("./",  // 证书路径
+                    "ca.crt",  // CA证书，用于验证服务器
+                    "client.crt",  // 客户端证书
+                    "client.key",  // 客户端私钥
+                    "127.0.0.1"  // 服务器主机名（SNI）
+    );
+```
+
+服务端配置：
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "ca.crt";  // CA证书，用于验证客户端
+ssl_conf.enable_client_verify = true;  // 启用客户端证书验证
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+**重要说明**：
+- `enable_client_verify` 标志启用强制客户端证书验证
+- 启用双向认证后，客户端必须提供由 `ca_cert_file` 指定的CA签发的有效证书
+- 主机名参数必须与服务器证书中的通用名称（CN）或主题备用名称（SAN）匹配
+
+我们同样支持国密NTLS。你需要开启CMAKE选项`YLT_ENABLE_NTLS`。
+
+## RPC参数的转换与编译期检查
+
+coro_rpc会在调用的时候对参数的合法性做编译期检查，比如，对于如下rpc函数：
+
+```cpp
+inline std::string echo(std::string str) { return str; }
+```
+
+接下来，当前client调用rpc函数时：
+
+```cpp
+client.call<echo>(42);// The argument does not match, a compilation error occurs.
+client.call<echo>();// Missing argument, compilation error occurs.
+client.call<echo>("", 0);// There are too many arguments, a compilation error occurs.
+client.call<echo>("hello, coro_rpc");// The string literal can be converted to std::string, compilation succeeds.
+```
+
+## 连接选项
+
+coro_rpc_client提供了`init_config`函数，用于配置连接选项。下面这份代码列出了可配置的选项。这些选项默认均可以不填写。
+
+```cpp
+using namespace coro_rpc;
+using namespace std::chrono;
+void set_config(coro_rpc_client& client) {
+  uint64_t client_id;
+  std::chrono::milliseconds connect_timeout_duration;
+  std::chrono::milliseconds request_timeout_duration;
+  std::string host;
+  std::string port;
+  std::string local_ip;
+  client.init_config(config{
+    .connect_timeout_duration = 5s, // 连接的超时时间
+    .request_timeout_duration = 5s, // 请求超时时间
+    .host = "localhost", // 服务器域名
+    .port = "9001", // 服务器端口
+    .local_ip = "", // 本地ip，用于指定本地通信的ip地址。
+    .socket_config=std::variant<tcp_config,
+                 tcp_with_ssl_config,
+                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // 指定底层的协议及其底层配置，目前支持tcp, ssl over tcp, rdma三种协议。
+  });
+}
+```
+
+
+### rdma配置
+
+ibverbs协议的配置如下：
+```cpp
+struct ib_socket_t::config_t {
+  uint32_t cq_size = 128; // 事件通知队列的最大长度
+  uint32_t recv_buffer_cnt = 8;                 // 默认提交到接受队列的缓冲数目，一个缓冲区默认256KB。积压的接收数据越多，队列中的缓冲区也会越多，最多可以缓冲max_recv_wr*buffer_size这么多的数据(buffer_size为buffer_pool配置的缓冲区大小），此后如果上层仍不消费数据，则发送端会收到rnr错误，不断重试并等待对端消费。
+  uint32_t send_buffer_cnt = 4;                 // 默认的发送缓冲区队列长度上限。代表最多积压的发送缓冲区数目。
+  ibv_qp_type qp_type = IBV_QPT_RC;             // 默认的qp类型。
+  ibv_qp_cap cap = {.max_send_wr = 32,           // 发送队列的最大长度。
+                    .max_recv_wr = 32,          // 接受队列的最大长度
+                    .max_send_sge = 3,          // 发送的最大地址分段数，在不启用inline data时只需要1个。使用inline data时数据可能不经过拷贝直接从原始分段地址发送，因此设置为3段（默认支持3段分散地址）。
+                    .max_recv_sge = 1,          // 接受的最大地址分段数，目前的缓冲区配置下只需要1个即可。
+                    .max_inline_data = 256};    // 如果发送的数据包小于inline data，且底层网卡支持该设置，则小数据包不会被拷贝到缓冲中，而是直接交给网卡发送。
+  std::shared_ptr<coro_io::ib_device_t> device; // rpc使用的底层ib网卡。默认选择设备列表第一个网卡。
+};
+```
+
+可以通过下面的代码简单的启用rdma：
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv(); //使用默认配置
+  cli.init_ibv(ib_socket_t::config_t{}); //使用用户指定的配置
+```
+
+也可以在配置中启用rdma：
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
+```
+
+
+#### ib_device_t
+
+`ib_device_t`管理了ibverbs传输过程中需要使用到的连接上下文和缓冲区。默认使用全局设备`coro_io::get_global_ib_device()`，用户也可以指定使用自己的设备。
+
+通过修改ib_device_t的配置，可以给rpc连接配置不同的网卡，使用独立的缓冲区。
+
+1. 修改默认的设备配置
+```cpp
+  // 配置只有在第一次调用时才会生效
+  coro_io::get_global_ib_device({ 
+    .buffer_pool_config = {
+      .buffer_size = 256 * 1024,  // 缓冲区大小
+      .max_memory_usage = 4 * 1024 * 1024, // 最大内存使用量（超过此限制将分配失败）
+      .memory_usage_recorder = nullptr; // nullopt 表示不同设备的内存占用会被一起统计，如果想要让内存池具有独立的内存占用记录，请分配一个非空的std::shared_ptr<std::atomic<std::size_t>>作为记录
+      .idle_timeout = 5s // 空闲时间超过这个时长的缓冲区将被回收
+    }
+  }); 
+  // ...
+```
+
+2. 初始化连接时，指定需要使用的 RDMA 网卡
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
+  });
+```
+
+3. 创建并使用自己的 `ib_device_t`
+```cpp
+  auto dev = coro_io::ib_device_t::create({
+    .dev_name = "",  // 如果 dev_name 为 空，则会使用设备列表中的第一个设备
+    .port = 1, // 手动指定网卡port
+    .use_best_gid_index = true, // 自动查找该设备最佳的gid_index
+    .gid_index = 0, // 手动指定gid_index，当关闭自动查找或自动查找失败时生效
+    .buffer_pool_config = {
+      // ...
+    },
+  });
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = dev
+  });
+```
+
+4. 查询当前所有成功注册的全局 RDMA 设备
+```cpp
+  // 获取所有设备
+  auto devices = coro_io::g_ib_device_manager();
+  for (auto &dev: devices.get_dev_list()) {
+    std::cout<<"name:"<<dev.first;
+    // dev.second 是一个全局的 std::shared_ptr<ib_device_t>
+  }
+```
+
+## 调用模型
+
+每一个`coro_rpc_client`都会绑定到某个IO线程上，默认通过轮转法从全局IO线程池中选择一个连接，用户也可以手动绑定到特定的IO线程上。
+
+```cpp
+auto executor=coro_io::get_global_executor();
+coro_rpc_client client(executor),client2(executor);
+// 两个客户端都被绑定到同一个io线程上
+```
+
+每次发起一个基于协程的IO任务（如`connect`,`call`,`send_request`），客户端内部会将IO事件提交给操作系统，当IO事件完成后，再将协程恢复到绑定的IO线程上继续执行。
+
+例如以下代码，调用connect之后任务将切换到IO线程执行。
+
+```cpp
+/*run in thread 1*/
+coro_rpc_client cli;
+co_await cli.connect("localhost:9001");
+/*run in thread 2*/
+do_something();
+```
+
+## 连接池与负载均衡
+
+`coro_io`提供了连接池`client_pool`与负载均衡器`channel`。用户可以通过连接池`client_pool`来管理`coro_rpc`/`coro_http`连接，可以使用`channel`实现多个host之间的负载均衡。具体请见`coro_io`的文档。
+
+## 连接复用
+
+`coro_rpc_client` 可以通过 `send_request`函数实现连接复用。该函数是线程安全的，允许多个线程同时调用同一个client的 `send_request`方法。该函数返回值为`Lazy<Lazy<async_rpc_result<T>>>`.
+
+
+连接复用允许我们在高并发下减少连接的个数，无需创建新的连接。同时也能提高每个连接的吞吐量。
+
+下面是一段简单的示例代码：
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string_view echo(std::string_view);
+Lazy<void> example(coro_rpc_client& client) {
+  //向服务器发送请求
+  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  if (result) {
+    assert(result->result() == "Hello");
+  }
+  else {
+    // error handle
+    std::cout<<result.error().msg()<<std::endl;
+  }
+}
+```
+
+我们可以多次调用send_request实现连接复用：
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string echo(std::string);
+Lazy<void> example(coro_rpc_client& client) {
+  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
+  // 准备发送10个请求
+  for (int i=0;i<10;++i) {
+    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
+  }
+  //接下来等待所有的请求返回
+  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
+  for (int i=0;i<10;++i) {
+    assert(results[i]->result() == std::to_string(i));
+  }
+  co_return;
+}
+```
+
+在使用连接池发送数据时，我们也可以复用连接，此时需要在添加`coro_io_client_reuse_hint`参数，提示连接池启用连接复用。详见连接池文档。（TODO）
+
+```cpp
+auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
+    conf.url, pool_conf);
+auto ret = co_await pool->send_request(
+    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
+        return client.send_request<echo>("hello");
+    });
+if (ret.has_value()) {
+    auto result = co_await std::move(ret.value());
+    if (result.has_value()) {
+        assert(result.value()=="hello"); 
+    }
+}
+```
+
+
+### Attachment
+
+使用`send_request`方法时，由于可能同时发送多个请求，因此我们不能调用`set_req_attachment`方法向服务器发送attachment，同样也不能调用`get_resp_attachment`和`release_resp_attachment`方法来获取服务器返回的attachment。
+
+我们可以通过调用`send_request_with_attachment`函数，在发送请求时设置attachment。我们也可以通过调用async_rpc_result的`->get_attachment()`方法和`->release_buffer()`方法来获取attachment。
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+int add(int a, int b);
+Lazy<std::string> example(coro_rpc_client& client) {
+  async_rpc_result<std::string_view> result = co_await co_await client.send_request_with_attachment<add>("Hello", 1, 2);
+  assert(result->result() == 3);
+  assert(result->get_attachment() == "Hello");
+  co_return std::move(result->release_buffer().resp_attachment_buf_);
+}
+```
+
+
+### 执行顺序
+
+当调用的rpc函数是协程rpc函数或回调rpc函数时，rpc请求不一定会按顺序执行，服务端可能会同时执行多个rpc请求。
+
+例如，假如有以下代码：
+
+```cpp
+using namespace async_simple::coro;
+Lazy<void> sleep(int seconds) {
+  co_await coro_io::sleep(1s * seconds);  // 在此处让出协程
+  co_return;
+}
+```
+
+服务器注册并启动：
+```cpp
+using namespace coro_rpc;
+void start() {
+  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
+  server.register_handler<sleep>();
+  server.start();
+}
+```
+
+客户端连续在同一个连接上调用两次sleep函数，第一次sleep2秒，第二次sleep1秒。
+```cpp
+using namespace async_simple::coro;
+using namespace coro_rpc;
+Lazy<void> call() {
+  coro_rpc_client cli,cli2;
+  co_await cli.connect("localhost:8801");
+  co_await cli2.connect("localhost:8801");
+  auto handler1 = co_await cli.send_request<sleep>(2);
+  auto handler2 = co_await cli.send_request<sleep>(1);
+  auto handler3 = co_await cli2.send_request<sleep>(0);
+  handler2.start([](auto&&){
+    std::cout<<"handler2 return"<<std::endl;
+  });
+  handler3.start([](auto&&){
+   d::cout<<"handler3 return"<<std::endl;
+  });
+  co_await handler1;
+  std::cout<<"handler1 return"<<std::endl;
+}
+```
+正常情况下handler3会先返回，随后是handler2，最后是handler1。尽管服务器只有一个IO线程用于执行rpc函数，但协程函数会在调用`coro_io::sleep`时让出该协程，从而保证其他连接不会被阻塞。
+
+### socket延迟发送
+
+当使用连接复用时，可以尝试将选项中的`enable_tcp_no_delay`设为`false`,这允许底层实现将多个小请求打包后一起发送，从而提高吞吐量，但是可能会导致延迟上升。
+
+## 线程安全
+
+对于多个coro_rpc_client实例，它们之间互不干扰，可以分别在不同的线程中安全的调用。
+
+单个coro_rpc_client在多个线程同时调用时需要注意，只有部分成员函数是线程安全的，包括`send_request()`,`close()`,`connect()`,`get_executor()`,`get_pipeline_size()`,`get_client_id()`,`get_config()`等。如果用户没有重新调用connect()函数并传入endpoint或hostname，那么`get_port()`,`get_host()`函数也是线程安全的。
+
+需要注意，`call`,`get_resp_attachment`,`set_req_attachment`,`release_resp_attachment`和`init_config`函数均不是线程安全的，禁止多个线程同时调用。此时只能使用`send_request`实现多个线程并发请求同一个连接。
+
+# coro_rpc 性能测试
+先编译coro_rpc 的bench再执行bench命令行，命令行详情：
+```
+options:
+  -u, --url                   url (string [=0.0.0.0:9000])
+  -s, --send_data_len         send data length (unsigned long [=8388608])
+  -c, --client_concurrency    total number of http clients (unsigned int [=0])
+  -m, --max_request_count     max request count (unsigned long [=100000000])
+  -p, --port                  server port (unsigned short [=9000])
+  -r, --resp_len              response data length (unsigned long [=13])
+  -b, --buffer_size           buffer size (unsigned int [=262144])
+  -o, --log_level             Severity::INFO 1 as default, WARN is 4 (int [=1])
+  -i, --enable_ib             enable ib (bool [=1])
+  -d, --duration              duration seconds (unsigned int [=100000])
+  -?, --help                  print this message
+```
+
+server侧命令行：
+`./bench -p 9004 -r 13 -o 5`
+
+含义：启动服务端，response的数据长度为13，日志级别为error(日志级别和easylog的日志级别对应)。
+
+client测命令行：
+`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
+
+含义：启动100个client去压测，每次请求发送8MB数据，日志级别为error，持续时间30秒。
+
+如果安装了ibverbs环境，则默认会启用ibverbs，如果希望只测试tcp则添加`-i 0`
+
+性能测试完成之后将输出qps，吞吐和latency数据，测试结果类似于：
+```
+# Benchmark result
+avg qps 2757 and throughput:185.04 Gb/s in duration 30
+# HELP Latency(us) of rpc call help
+# TYPE Latency(us) of rpc call summary
+rpc call latency(us){quantile="0.500000"} 3616.000000
+rpc call latency(us){quantile="0.900000"} 3712.000000
+rpc call latency(us){quantile="0.950000"} 3776.000000
+rpc call latency(us){quantile="0.990000"} 3872.000000
+rpc call latency(us)_sum 298707968.000000
+rpc call latency(us)_count 82761
 ```

Subject: [PATCH 30/38] feat: add SSL mutual authentication support

- Add init_ssl with client certificate for mutual auth (RPC & HTTP)
- Set is_ssl_schema_ = true in init_ssl()
- Set SSL security level to 0 for test certificates (OpenSSL 3.0)
- Change SSL context from sslv23 to tls for modern TLS
- Skip hostname verification for IP addresses
- Add mutual auth test files and certificates
- Add SSL mutual auth documentation

+# NTLS CI 快速检查清单
+
+## ✅ 如何确认CI使用了你的配置
+
+### 步骤1：确认文件已提交
+```bash
+# 在你的fork仓库中检查
+git log --oneline --all -- .github/workflows/ntls_test.yml
+# 应该能看到你提交的记录
+```
+
+### 步骤2：在GitHub上检查
+
+#### 方法A：在PR页面查看（推荐）
+1. 打开你的PR页面
+2. 向下滚动到"Checks"部分
+3. **如果看到 "NTLS Test (Tongsuo)" 工作流** ✅
+   - 说明CI正在使用你的配置
+   - 点击可以查看详细运行情况
+
+#### 方法B：在Actions页面查看
+1. 进入**你的fork仓库**（不是主仓库）
+2. 点击顶部的 **"Actions"** 标签
+3. **如果左侧列表中有 "NTLS Test (Tongsuo)"** ✅
+   - 说明配置已生效
+4. 点击工作流名称，查看运行历史
+
+#### 方法C：查看CI日志确认
+1. 在PR的"Checks"部分，点击 "NTLS Test (Tongsuo)"
+2. 点击具体的job（如 "ntls_test_ubuntu"）
+3. 展开 "Configure CMake with NTLS" 步骤
+4. **在日志中查找 `YLT_ENABLE_NTLS: ON`** ✅
+   - 如果看到这个输出，说明使用了你的配置
+
+### 步骤3：验证关键特征
+
+你的CI配置应该包含以下特征，在日志中可以验证：
+
+- ✅ **编译Tongsuo库** - 日志中应该有 "Build and install Tongsuo" 步骤
+- ✅ **配置CMake启用NTLS** - 日志中应该有 `-DYLT_ENABLE_NTLS=ON`
+- ✅ **编译NTLS示例** - 日志中应该有 "Verify NTLS examples are built" 步骤
+- ✅ **使用Tongsuo路径** - 日志中应该有 `/usr/local/tongsuo` 相关路径
+
+## 🔍 如何区分fork的CI和主仓库的CI
+
+### 关键区别
+
+| 特征 | Fork的CI | 主仓库的CI |
+|------|---------|-----------|
+| 工作流名称 | "NTLS Test (Tongsuo)" | 不存在（除非他们也添加了） |
+| 显示位置 | 你的fork仓库的Actions页面 | 主仓库的Actions页面 |
+| PR中的显示 | 会显示在你的PR中 | 不会显示（除非主仓库有） |
+
+### 确认方法
+
+1. **查看工作流来源**
+   - 在PR的"Checks"部分，每个检查旁边会显示来源
+   - 如果显示你的用户名，说明是fork的CI
+   - 如果显示主仓库名，说明是主仓库的CI
+
+2. **检查工作流文件位置**
+   - Fork的CI：`.github/workflows/ntls_test.yml` 在你的fork中
+   - 主仓库的CI：`.github/workflows/ntls_test.yml` 在主仓库中
+
+## 🚨 常见问题

+# NTLS CI 测试说明
+
+本文档说明如何使用GitHub Actions CI来测试NTLS（国密SSL）功能。
+
+## 概述
+
+由于NTLS功能依赖于Tongsuo库（而不是标准的OpenSSL），原仓库的CI配置无法测试NTLS相关功能。因此，我们创建了专门的CI工作流来测试NTLS功能。
+
+## CI工作流
+
+### 文件位置
+
+CI配置文件位于：`.github/workflows/ntls_test.yml`
+
+### 触发条件
+
+该工作流会在以下情况触发：
+- 推送到 `main` 或 `develop` 分支
+- 创建或更新PR到 `main` 或 `develop` 分支
+- 手动触发（workflow_dispatch）
+- 当相关文件发生变化时（包括NTLS相关代码、CMake配置、证书文件等）
+
+### 测试内容
+
+CI工作流会执行以下步骤：
+
+1. **安装Tongsuo库**
+   - 从源码编译安装Tongsuo（支持NTLS的OpenSSL分支）
+   - 启用NTLS、SM2、SM3、SM4等国密算法支持
+
+2. **配置和编译**
+   - 使用CMake配置项目，启用SSL和NTLS支持
+   - 编译NTLS相关的示例程序（`ntls_server`, `ntls_client`等）
+
+3. **验证**
+   - 检查NTLS示例程序是否成功编译
+   - 验证Tongsuo库中的NTLS符号
+   - 运行基本测试
+
+### 支持的编译器
+
+- GCC
+- Clang 17
+
+### 构建模式
+
+- Debug模式
+
+## 使用方法
+
+### 在Fork的仓库中
+
+1. **将CI文件添加到你的fork**
+   ```bash
+   git add .github/workflows/ntls_test.yml
+   git commit -m "Add NTLS CI workflow"
+   git push
+   ```
+
+2. **创建或更新PR**
+   - 当你创建PR时，CI会自动运行
+   - 你可以在PR页面看到CI运行状态
+
+3. **查看CI结果**
+   - 在PR页面点击"Checks"标签
+   - 查看"NTLS Test (Tongsuo)"工作流的运行结果
+
+### 如何确认CI使用了你的配置
+
+#### 方法1：查看PR中的CI运行状态
+
+1. **在PR页面查看**
+   - 打开你的PR页面
+   - 向下滚动，你会看到"Checks"部分
+   - 如果看到"NTLS Test (Tongsuo)"工作流，说明CI正在运行
+   - 点击工作流名称可以查看详细信息
+
+2. **检查工作流名称**
+   - 如果看到 `NTLS Test (Tongsuo)` 这个工作流名称，说明使用了你的配置
+   - 主仓库的CI不会包含这个工作流（除非他们也添加了）
+
+#### 方法2：在Actions页面查看
+
+1. **在你的fork仓库中**
+   - 进入你的fork仓库（不是主仓库）
+   - 点击顶部的"Actions"标签
+   - 在左侧工作流列表中找到"NTLS Test (Tongsuo)"
+   - 如果能看到这个工作流，说明配置已生效
+
+2. **查看运行历史**
+   - 点击工作流名称
+   - 查看运行历史，确认是否有新的运行记录
+   - 每次推送代码或更新PR时，应该会触发新的运行
+
+#### 方法3：检查工作流文件是否存在
+
+在你的fork仓库中检查：
+```bash
+# 在你的fork仓库中运行
+ls -la .github/workflows/ntls_test.yml
+```
+
+如果文件存在，CI应该会使用它。
+
+#### 方法4：查看CI日志确认
+
+1. **打开CI运行详情**
+   - 在PR页面点击"Checks"标签
+   - 点击"NTLS Test (Tongsuo)"工作流
+   - 点击具体的job（如"ntls_test_ubuntu"）
+
+2. **检查关键步骤**
+   - 查看"Build and install Tongsuo"步骤
+   - 查看"Configure CMake with NTLS"步骤
+   - 如果这些步骤存在且成功，说明使用了你的CI配置
+
+3. **查看CMake配置输出**
+   - 在"Configure CMake with NTLS"步骤的日志中
+   - 应该能看到 `YLT_ENABLE_NTLS: ON` 的输出
+   - 这证明CMake使用了你的配置
+
+#### 方法5：通过GitHub API检查（高级）
+
+如果你想通过API检查，可以使用：
+```bash
+# 获取工作流列表
+curl -H "Authorization: token YOUR_TOKEN" \
+  https://api.github.com/repos/YOUR_USERNAME/yalantinglibs/actions/workflows
+```
+
+#### 常见问题排查
+
+**问题1：看不到CI运行**
+- 确认 `.github/workflows/ntls_test.yml` 文件已提交到你的fork
+- 检查文件路径是否正确（`.github/workflows/` 目录）
+- 确认文件格式正确（YAML语法）
+
+**问题2：CI运行但失败**
+- 查看CI日志中的错误信息
+- 检查Tongsuo编译是否成功
+- 确认CMake配置是否正确
+
+**问题3：CI没有自动触发**
+- 检查工作流的触发条件（`on:` 部分）
+- 确认你修改的文件在触发路径中
+- 可以手动触发（workflow_dispatch）
+
+**问题4：不确定是否使用了fork的CI还是主仓库的CI**
+- Fork的CI会在你的fork仓库的Actions页面显示
+- PR中的CI检查会显示来源仓库
+- 如果主仓库没有这个工作流，那么运行的肯定是你的配置
+
+### 手动触发
+
+如果需要手动触发CI：
+
+1. **在你的fork仓库中**
+   - 进入你的fork仓库（不是主仓库）
+   - 点击"Actions"标签
+   - 选择"NTLS Test (Tongsuo)"工作流
+   - 点击"Run workflow"按钮
+   - 选择分支（通常是你的PR分支）
+   - 点击绿色的"Run workflow"按钮
+
+2. **在PR中触发**
+   - 如果PR已经创建，可以重新推送代码来触发
+   - 或者关闭并重新打开PR
+
+## 本地测试
+
+如果你想在本地测试NTLS功能，可以按照以下步骤：
+
+### 1. 安装Tongsuo
+
+```bash
+# 克隆Tongsuo仓库
+git clone https://github.com/Tongsuo-Project/Tongsuo.git
+cd Tongsuo
+
+# 配置和编译
+./config --prefix=/usr/local/tongsuo \
+         --openssldir=/usr/local/tongsuo/ssl \
+         shared \
+         -fPIC \
+         enable-ntls \
+         enable-sm2 \
+         enable-sm3 \
+         enable-sm4 \
+         enable-tls1_3
+
+make -j$(nproc)
+sudo make install
+sudo ldconfig
+```
+
+### 2. 配置环境变量
+
+```bash
+export PATH=/usr/local/tongsuo/bin:$PATH
+export LD_LIBRARY_PATH=/usr/local/tongsuo/lib:$LD_LIBRARY_PATH
+export PKG_CONFIG_PATH=/usr/local/tongsuo/lib/pkgconfig:$PKG_CONFIG_PATH
+```
+
+### 3. 编译项目
+
+```bash
+mkdir build && cd build
+cmake .. \
+    -DYLT_ENABLE_SSL=ON \
+    -DYLT_ENABLE_NTLS=ON \
+    -DCMAKE_PREFIX_PATH=/usr/local/tongsuo \
+    -DOPENSSL_ROOT_DIR=/usr/local/tongsuo
+
+make -j$(nproc)
+```
+
+### 4. 运行示例
+
+```bash
+# 运行NTLS服务器示例
+./src/coro_rpc/examples/base_examples/ntls_server
+
+# 在另一个终端运行客户端
+./src/coro_rpc/examples/base_examples/ntls_client
+```
+
+## 关于Fork和PR的说明
+
+### 权限问题
+
+- **你不能直接修改主仓库的CI配置**
+- 但是，**你可以在自己的fork中创建CI配置**
+- 当你提交PR时，fork中的CI会运行，结果会显示在PR中
+
+### 最佳实践
+
+1. **在fork中创建CI配置**
+   - 将`.github/workflows/ntls_test.yml`添加到你的fork
+   - 这样每次推送代码时，CI会自动运行
+
+2. **在PR中说明**
+   - 在PR描述中说明你添加了NTLS CI测试
+   - 提供CI运行结果的链接
+
+3. **与维护者沟通**
+   - 如果主仓库维护者希望合并你的CI配置，他们可以接受你的PR
+   - 或者，他们可以参考你的CI配置，在主仓库中创建类似的配置
+
+## 故障排除
+
+### CI失败常见原因
+
+1. **Tongsuo编译失败**
+   - 检查Tongsuo版本是否可用
+   - 确认所有依赖都已安装
+
+2. **CMake找不到Tongsuo**
+   - 检查`CMAKE_PREFIX_PATH`和`OPENSSL_ROOT_DIR`设置
+   - 确认库文件路径正确
+
+3. **链接错误**
+   - 确认`LD_LIBRARY_PATH`包含Tongsuo库路径
+   - 检查库文件是否存在
+
+### 调试建议
+
+1. 查看CI日志中的详细错误信息
+2. 在本地复现相同的环境进行测试
+3. 检查Tongsuo版本兼容性

+
+## 关于测试环境的选择
+
+### 当前CI配置
+
+当前的NTLS CI配置测试了以下环境：
+- ✅ Ubuntu 22.04 + GCC
+- ✅ Ubuntu 22.04 + Clang 17
+
+### 是否需要测试所有环境？
+
+**简短回答：不需要。** 对于PR测试，测试主要环境就足够了。
+
+### 为什么不需要所有环境？
+
+1. **Tongsuo库的平台支持**
+   - Tongsuo主要在Linux平台上使用和测试
+   - Linux是NTLS功能的主要部署环境
+   - Mac和Windows上的Tongsuo支持可能有限或需要额外配置
+
+2. **PR测试的目的**
+   - PR中的CI主要用于验证代码能正常编译和基本功能
+   - 不需要覆盖所有可能的部署环境
+   - 主仓库的CI会处理其他环境的测试
+
+3. **资源效率**
+   - 测试所有环境会消耗大量CI资源
+   - 增加CI运行时间，影响开发效率
+   - 对于fork的PR，资源可能有限
+
+4. **编译器差异**
+   - 当前配置已经测试了GCC和Clang两个主要编译器
+   - 这已经覆盖了大部分编译问题
+   - MSVC的测试可以在主仓库合并后进行
+
+### 建议的测试策略
+
+#### 最小配置（推荐用于PR）
+- ✅ Ubuntu + GCC（主要编译器）
+- ✅ Ubuntu + Clang（验证C++标准兼容性）
+
+**理由：**
+- 覆盖了主要的Linux部署环境
+- 测试了两个主要编译器
+- 资源消耗合理
+- 足以验证NTLS功能的基本正确性
+
+#### 完整配置（如果资源充足）
+如果主仓库维护者希望，可以添加：
+- Ubuntu + GCC
+- Ubuntu + Clang
+- ~~Mac + Clang~~（Tongsuo在Mac上支持有限）
+- ~~Windows + MSVC~~（Tongsuo在Windows上支持有限）
+
+**注意：** Mac和Windows上的Tongsuo支持可能需要额外配置，不建议在PR阶段测试。
+
+### 什么时候需要添加更多环境？
+
+1. **主仓库要求**
+   - 如果维护者明确要求测试特定环境
+   - 如果项目有跨平台部署需求
+
+2. **功能需要**
+   - 如果你的NTLS功能有平台特定的代码
+   - 如果需要验证特定平台的兼容性
+
+3. **资源充足**
+   - 如果你的fork有充足的CI资源
+   - 如果测试时间不是问题
+
+### 当前配置是否足够？
+
+**是的，当前配置已经足够用于PR测试：**
+
+✅ **优点：**
+- 测试了主要部署平台（Linux）
+- 覆盖了两个主要编译器（GCC、Clang）
+- 资源消耗合理
+- 足以验证NTLS功能的基本正确性
+
+✅ **验证内容：**
+- NTLS代码能够编译
+- Tongsuo库能够正确链接
+- CMake配置正确
+- 基本功能正常
+
+### 与维护者沟通
+
+在PR中，你可以说明：
+- 当前CI测试了Linux上的GCC和Clang
+- 这是NTLS功能的主要部署环境
+- 如果需要，可以在主仓库合并后添加其他环境的测试
+- 或者，如果维护者需要，可以添加更多环境的测试
+
+### 总结
+
+**对于PR测试：**
+- ✅ 测试主要环境（Linux + GCC/Clang）就足够了
+- ❌ 不需要测试所有环境（Mac、Windows等）
+- ✅ 当前配置已经合理且足够
+
+**如果主仓库合并后：**
+- 维护者可以根据需要添加其他环境的测试
+- 或者你可以在后续PR中添加更多环境的支持
+
+## 更新日志
+
+- 2025-01-XX: 初始版本，支持Ubuntu 22.04上的GCC和Clang测试

+# SM2 Certificates for NTLS Examples
+
+This directory contains SM2 certificates for NTLS (国密SSL) examples using Tongsuo.
+
+## Certificate Files
+
+- `sm2_sign.crt` - SM2 signing certificate
+- `sm2_sign.key` - SM2 signing private key
+- `sm2_enc.crt` - SM2 encryption certificate  
+- `sm2_enc.key` - SM2 encryption private key
+- `ca.crt` - CA certificate (optional)
+
+## Generating SM2 Certificates with Tongsuo
+
+To generate your own SM2 certificates using Tongsuo, follow these steps:
+
+### 1. Generate CA private key and certificate
+```bash
+# Generate CA private key
+tongsuo genpkey -algorithm SM2 -out ca.key
+
+# Generate CA certificate
+tongsuo req -new -x509 -key ca.key -out ca.crt -days 365 \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=Test CA"
+```
+
+### 2. Generate server signing certificate
+```bash
+# Generate server signing private key
+tongsuo genpkey -algorithm SM2 -out sm2_sign.key
+
+# Generate server signing certificate request
+tongsuo req -new -key sm2_sign.key -out sm2_sign.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=localhost"
+
+# Sign the certificate request
+tongsuo x509 -req -in sm2_sign.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out sm2_sign.crt -days 365
+```
+
+### 3. Generate server encryption certificate
+```bash
+# Generate server encryption private key
+tongsuo genpkey -algorithm SM2 -out sm2_enc.key
+
+# Generate server encryption certificate request
+tongsuo req -new -key sm2_enc.key -out sm2_enc.csr \
+    -subj "/C=CN/ST=Beijing/L=Beijing/O=Test/OU=Test/CN=localhost"
+
+# Sign the certificate request
+tongsuo x509 -req -in sm2_enc.csr -CA ca.crt -CAkey ca.key \
+    -CAcreateserial -out sm2_enc.crt -days 365
+```
+
+### 4. Clean up temporary files
+```bash
+rm *.csr *.srl
+```
+
+## Usage
+
+These certificates are used by the NTLS examples:
+- `ntls_server.cpp` - NTLS RPC server example
+- `ntls_client.cpp` - NTLS RPC client example
+
+Make sure Tongsuo is properly installed and configured before running the examples.
+
+## Security Note
+
+The certificates in this directory are for testing purposes only. 
+Do not use them in production environments.

+#HTTP SSL Mutual Authentication
+
+##Overview
+
+                coro_http supports SSL /
+            TLS encrypted connections using OpenSSL.This document describes how
+                to configure both one -
+        way(server authentication) and
+    mutual(client and server authentication) SSL / TLS authentication.
+
+                                                   ##Enabling SSL Support
+
+                                                   After installing OpenSSL,
+    enable SSL support by setting the CMake option :
+
+```cmake option(YLT_ENABLE_SSL "Enable SSL support" ON)
+```
+
+    Or manually add the `YLT_ENABLE_SSL` macro and link to OpenSSL.
+
+    ##One
+        -
+        way SSL Authentication
+
+        One
+        -
+        way SSL authentication(server authentication only)
+            ensures that the client verifies the server
+        's certificate but doesn' t require the client to present a certificate.
+
+        ## #Client
+        -
+        side Configuration
+
+```cpp
+#include <ylt/coro_http/coro_http_client.hpp>

+
+## Mutual SSL Authentication
+
+Mutual SSL authentication (mTLS) requires both client and server to present valid certificates, providing strong security for sensitive applications.
+
+### Client-side Configuration
+
+```cpp
+#include <ylt/coro_http/coro_http_client.hpp>
+
+using namespace cinatra;
+
+coro_http_client client;
+bool init_ok =
+    client.init_ssl(asio::ssl::verify_peer,  // Verify server certificate

+}
+```
+
+    ## #Server -

+  resp.set_status_and_content(status_type::ok, "Hello Mutual Auth!");
+});
+
+server.sync_start();
+```
+
+    ##Certificate Management
+
+    ## #Generating Test Certificates
+
+        For testing purposes,
+    you can generate self -
+        signed certificates using OpenSSL :
+
+    ####Generate CA Certificate
+
+```bash
+#Generate CA private key
+        openssl genrsa -
+    out ca.key 2048
+
+#Generate CA certificate
+    openssl req -
+    new - x509 - days 3650 - key ca.key - out ca.crt -
+    subj "/C=CN/ST=Beijing/L=Beijing/O=MyOrg/CN=TestCA"
+```
+
+    ####Generate Server Certificate
+
+```bash
+#Generate server private key
+        openssl genrsa -
+    out server.key 2048
+
+#Generate server certificate signing request
+    openssl req -
+    new - key server.key - out server.csr -
+    subj "/C=CN/ST=Beijing/L=Beijing/O=MyOrg/CN=127.0.0.1"
+
+#Sign server certificate with CA
+    openssl x509 -
+    req - days 3650 - in server.csr - CA ca.crt - CAkey ca.key -
+    CAcreateserial -
+    out server.crt
+```
+
+    ####Generate Client Certificate
+
+```bash
+#Generate client private key
+        openssl genrsa -
+    out client.key 2048
+
+#Generate client certificate signing request
+    openssl req -
+    new - key client.key - out client.csr -
+    subj "/C=CN/ST=Beijing/L=Beijing/O=MyOrg/CN=TestClient"
+
+#Sign client certificate with CA
+    openssl x509 -
+    req - days 3650 - in client.csr - CA ca.crt - CAkey ca.key -
+    CAcreateserial -
+    out client.crt
+```
+
+    ## #Certificate Requirements
+
+    -
+    **Server Certificate *
+         * : Must contain the server's IP address or hostname in the Common Name (CN) or Subject Alternative Name (SAN) -
+                 **Client Certificate *
+                     * : Must be signed by the CA certificate specified in the
+                             server's `ca_cert_file` - **CA Certificate *
+                                 * : The root CA certificate that signed both
+                                         server and client certificates -
+    **Certificate Chain ** : For production use,
+    ensure proper certificate chains are configured
+
+    ##Verification Modes
+
+        The `init_ssl` function supports different verification modes :
+
+```cpp const int verify_none = asio::ssl::verify_none;  // No verification
+const int verify_peer = asio::ssl::verify_peer;  // Verify peer certificate
+const int verify_fail_if_no_peer_cert =
+    asio::ssl::verify_fail_if_no_peer_cert;  // Fail if no peer cert
+const int verify_client_once =
+    asio::ssl::verify_client_once;  // Verify client once
+```
+
+**Recommended Settings**:
+- **One-way auth**: `asio::ssl::verify_peer`
+- **Mutual auth**: `asio::ssl::verify_peer | asio::ssl::verify_fail_if_no_peer_cert` (automatically set when `enable_client_verify=true` on server)
+
+## Best Practices
+
+1. **Use Strong Certificates**: In production, use certificates signed by a trusted CA
+2. **Proper Hostname Matching**: Ensure the hostname parameter matches the certificate CN
+3. **Secure Private Keys**: Never commit private keys to version control
+4. **Certificate Rotation**: Implement procedures for rotating certificates before expiration
+5. **Error Handling**: Always check the return value of `init_ssl()` and handle errors appropriately
+6. **Testing**: Test both successful and failed authentication scenarios
+
+## Troubleshooting
+
+### Connection Failures
+
+If the client fails to connect:
+
+1. **Check Certificate Validity**: Ensure certificates are not expired
+2. **Verify Hostname**: Ensure the SNI hostname matches the certificate CN
+3. **Check CA Chain**: Ensure the CA certificate is correct and includes the full chain
+4. **Verify File Paths**: Ensure certificate file paths are correct and accessible
+
+### Certificate Verification Errors
+
+Common errors and solutions:
+
+- **"certificate verify failed"**: CA certificate doesn't match or is missing
+- **"hostname mismatch"**: SNI hostname doesn't match certificate CN
+- **"unable to get local issuer certificate"**: CA certificate not provided
+- **"no shared cipher"**: SSL/TLS version or cipher suite mismatch
+
+### Debug Mode
+
+Enable SSL debugging for troubleshooting:
+
+```cpp
+#ifdef YLT_ENABLE_SSL
+// Set SSL debug mode (environment variable)
+// On Linux/Mac:
+putenv("OPENSSL_DEBUG=1");
+
+// Or use detailed error messages
+SSL_load_error_strings();
+ERR_print_errors_fp(stderr);
+#endif
+```

-# Introduction to coro_rpc Client
-
-## Base Usage
-
-class `coro_rpc::coro_rpc_client` is the client side of coro_rpc, allowing users to send RPC requests to the server. 
-
-Below, we will demonstrate the basic usage of rpc_client.
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-int add(int a,int b);
-Lazy<void> example() {
-  coro_rpc_client client;
-  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
-  if (ec) { /*check if connection error*/
-    std::cout<<ec.message()<<std::endl;
-    co_return;
-  }
-  rpc_result result = co_await client.call<add>(1,2);
-  /*rpc_result is type of expected<T,rpc_error>, which T is rpc return type*/
-  if (!result.has_value()) {
-    /*call result.error() to get rpc error message*/
-    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
-    co_return;
-  }
-  assert(result.value()==3); /*call result.value() to  get rpc return type*/
-}
-```
-
-You can use the `set_req_attachment` function to set the attachment for the current request. This is a piece of binary data that will be sent directly to the client without serialization. Similarly, you can also use `get_resp_attachment()` and `release_resp_attachment()` to retrieve the attachment returned by the RPC request.
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-void attachment_echo() {
-  auto ctx=coro_rpc::get_context();
-  ctx->set_resp_attachment(ctx->get_req_attachment());
-}
-Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
-  client.set_req_attachment(attachment);
-  rpc_result result = co_await client.call<attachment_echo>();
-  if (result.has_value()) {
-    assert(result.get_resp_attachment()==attachment);
-    co_return std::move(result.release_resp_attachment());
-  }
-  co_return "";
-}
-```
-
-By default, the RPC client will wait for 5 seconds after sending a request/establishing a connection. If no response is received after 5 seconds, it will return a timeout error. Users can also customize the wait duration by calling the `call_for` function.
-
-```cpp
-client.connect("127.0.0.1:9001", std::chrono::seconds{10});
-auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
-assert(result.value() == 3);
-```
-
-The duration can be any `std::chrono::duration` type, common examples include `std::chrono::seconds` and `std::chrono::milliseconds`. Notably, if the duration is set to zero, it indicates that the function call will never time out.
-
-## SSL support
-
-coro_rpc supports using OpenSSL to encrypt connections. After installing OpenSSL and importing yalantinglibs into your project with CMake's `find_package` or `fetch_content`, you can enable SSL support by setting the CMake option YLT_ENABLE_SSL=ON. Alternatively, you might manually add the YLT_ENABLE_SSL macro and manually link to OpenSSL.
-
-Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It��s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
-
-For one -way SSL authentication(server authentication only),you can use the `init_ssl` function before establishing a connection:The first parameter is the base path where the SSL certificates are located, and the second parameter is the CA certificate filename for verifying the server.
-
-Server-side configuration:
-
-```cpp
-coro_rpc_server server(2, 9000);
-ssl_configure ssl_conf;
-ssl_conf.base_path = "./certs";
-ssl_conf.cert_file = "server.crt";
-ssl_conf.key_file = "server.key";
-ssl_conf.ca_cert_file = "";  // Empty for one-way authentication
-ssl_conf.enable_client_verify = false;  // Disable client certificate verification
-
-server.init_ssl(ssl_conf);
-server.register_handler<your_function>();
-server.start();
-```
-
-Mutual SSL Authentication For mutual SSL authentication(both client and server authentication),the client needs to provide its own certificate :
-
-```cpp
-    // Client-side mutual authentication
-    client.init_ssl("./",  // Base path
-                    "ca.crt",  // CA certificate for server verification
-                    "client.crt",  // Client certificate
-                    "client.key",  // Client private key
-                    "127.0.0.1"  // Server hostname for SNI
-    );
-```
-
-Server-side configuration for mutual authentication:
-
-```cpp
-coro_rpc_server server(2, 9000);
-ssl_configure ssl_conf;
-ssl_conf.base_path = "./certs";
-ssl_conf.cert_file = "server.crt";
-ssl_conf.key_file = "server.key";
-ssl_conf.ca_cert_file = "ca.crt";  // CA certificate for verifying clients
-ssl_conf.enable_client_verify = true;  // Enable mandatory client certificate verification
-
-server.init_ssl(ssl_conf);
-server.register_handler<your_function>();
-server.start();
-```
-
-**Important Notes**:
-- The `enable_client_verify` flag enables mandatory client certificate verification
-- When mutual authentication is enabled, clients must provide a valid certificate signed by the CA specified in `ca_cert_file`
-- The hostname parameter must match the Common Name (CN) in the server certificate
-
-We also support NTLS if you enable it by CMAKE OPTION `YLT_ENABLE_NTLS`.
-
-## Conversion and compile-time checking of RPC parameters
-
-coro_rpc will perform compile-time checks on the validity of arguments during invocation. For example, for the following rpc function:
-
-```cpp
-inline std::string echo(std::string str) { return str; }
-```
-
-Next, when the current client invokes the rpc function:
-
-```cpp
-client.call<echo>(42); // Parameter does not match, compilation error
-client.call<echo>(); // Missing parameter, compilation error
-client.call<echo>("", 0); // Extra parameters, compilation error
-client.call<echo>("hello, coro_rpc"); // The string literal can be converted to std::string, compilation succeeds
-```
-
-## Connection Options
-
-The `coro_rpc_client` provides an `init_config` function to configure connection options. The code below lists all configurable options, which are optional with default values.
-
-```cpp
-using namespace coro_rpc;
-using namespace std::chrono;
-void set_config(coro_rpc_client& client) {
-  uint64_t client_id;
-  std::chrono::milliseconds connect_timeout_duration;
-  std::chrono::milliseconds request_timeout_duration;
-  std::string host;
-  std::string port;
-  std::string local_ip;
-  client.init_config(config{
-    .connect_timeout_duration = 5s, // Connection timeout duration
-    .request_timeout_duration = 5s, // Request timeout duration
-    .host = "localhost", // Server hostname
-    .port = "9001", // Server port
-    .local_ip = "", // Local IP address used to specify the local communication interface
-    .socket_config=std::variant<tcp_config,
-                 tcp_with_ssl_config,
-                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // Specify transport protocol and its configuration. Supported protocols: TCP, SSL over TCP, RDMA
-  });
-}
-```
-
-### RDMA Socket Configuration
-
-The configuration for IBVerbs socket protocol is shown below:
-
-```cpp
-struct ib_socket_t::config_t {
-  uint32_t cq_size = 128; // Maximum length of event notification queue
-  uint32_t recv_buffer_cnt = 8;                 // Number of buffers pre-submitted to receive queue. Each buffer defaults to 256KB, so a RDMA connection occupies 8MB memory immediately after establishment. More pending receive data will result in more buffers in the queue, up to max_recv_wr*buffer_size (where buffer_size is configured in buffer_pool). If upper layer doesn't consume data, sender will receive RNR (Receiver Not Ready) errors and retry continuously.
-  uint32_t send_buffer_cnt = 4;                 // default send buffer queue max size,
-  ibv_qp_type qp_type = IBV_QPT_RC;             // Default QP type
-  ibv_qp_cap cap = {.max_send_wr = 32,           // Maximum send queue length
-                    .max_recv_wr = 32,          // Maximum receive queue length
-                    .max_send_sge = 3,          // Maximum send scatter/gather elements. Only 1 needed without inline data. Use 3 segments when using inline data (default supports 3 scattered addresses)
-                    .max_recv_sge = 1,          // Maximum receive scatter/gather elements. 1 suffices with current buffer configuration
-                    .max_inline_data = 256};    // If packet size < inline data threshold and NIC supports it, small packets bypass buffer copy and go directly to NIC
-  std::shared_ptr<coro_io::ib_device_t> device; // Underlying IB device for RPC. Defaults to first device in list
-};
-```
-
-Simple RDMA activation examples:
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv(); // Use default configuration
-  cli.init_ibv({.recv_buffer_cnt=8}); // Use custom configuration
-```
-
-RDMA activation through config:
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
-```
-
-#### RDMA Device Configuration
-
-The `ib_device_t` manages the connection context and buffers required during the ibverbs transmission process. By default, it uses the global device `coro_io::get_global_ib_device()`, but users can also specify their own device.
-
-By modifying the configuration of `ib_device_t`, users can assign different network interfaces to RPC connections and use separate buffers.
-
-1. Modify the default device configuration
-```cpp
-  // The configuration only takes effect on the first invocation
-  coro_io::get_global_ib_device({ 
-    .buffer_pool_config = {
-      .buffer_size = 256 * 1024,  // Buffer size
-      .max_memory_usage = 4 * 1024 * 1024, // Max memory usage (allocation fails beyond this limit)
-      .memory_usage_recorder = nullptr; // nullopt means that memory usage across different devices will be counted together. If you want the memory pool to have independent memory usage tracking, you should assign a non-null std::shared_ptr<std::atomic<std::size_t>> as the recorder.
-      .idle_timeout = 5s // Buffers unused for this duration will be reclaimed
-  }
-  });
-  // ...
-```
-
-      2. Specify the RDMA NIC to use when initializing the connection
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
-  });
-```
-
-      3. Create and use your own `ib_device_t`
-```cpp
-  auto dev = coro_io::ib_device_t::create({
-      .dev_name = "",  // If dev_name is empty, the first device in the device list will be used.
-      .port = 1,       // Manually specify the NIC port number.
-           .use_best_gid_index = true,  // Automatically find the best GID index for this device.
-      .gid_index = 0,   // Manually specify the GID index; takes effect when automatic lookup is disabled or fails.
-           .buffer_pool_config = {
-               // ...
-      }
-  });
-```
-
-      4. Query all currently successfully registered RDMA global devices
-```cpp
-      // Get all devices
-      auto devices = coro_io::g_ib_device_manager();
-  for (auto &dev: devices.get_dev_list()) {
-    std::cout << "name:" << dev.first;
-    // dev.second is a global std::shared_ptr<ib_device_t>
-  }
-```
-
-## Calling Model
-
-Each `coro_rpc_client` is bound to a specific IO thread. By default, it selects a connection via round-robin from the global IO thread pool. Users can also manually bind it to a specific IO thread.
-
-```cpp
-auto executor=coro_io::get_global_executor();
-coro_rpc_client client(executor),client2(executor);
-  // Both clients are bound to the same IO thread.
-```
-
-Each time a coroutine-based IO task is initiated (such as `connect`, `call`, `send_request`), the client internally submits the IO event to the operating system. When the IO event is completed, the coroutine is then resumed on the bound IO thread to continue execution. For example, in the following code, the task switches to the IO thread for execution after calling connect.
-
-```cpp
-/*run in thread 1*/
-coro_rpc_client cli;
-co_await cli.connect("localhost:9001");
-/*run in thread 2*/
-do_something();
-```
-
-## Connection Pool and Load Balancing
-
-`coro_io` offers a connection pool `client_pool` and a load balancer `channel`. Users can manage `coro_rpc`/`coro_http` connections through the `client_pool`, and can use `channel` to achieve load balancing among multiple hosts. For more details, please refer to the documentation of `coro_io`.
-
-## Connection Reuse
-
-The `coro_rpc_client` can achieve connection reuse through the `send_request` function. This function is thread-safe, allowing multiple threads to call the `send_request` method on the same client concurrently. The return value of the function is `Lazy<Lazy<async_rpc_result<T>>>`. The first `co_await` waits for the request to be sent, and the second `co_await` waits for the rpc result to return.
-
-
-Connection reuse allows us to reduce the number of connections under high concurrency, eliminating the need to create new connections. It also improves the throughput of each connection.
-
-Here's a simple example code snippet:
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string_view echo(std::string_view);
-Lazy<void> example(coro_rpc_client& client) {
-  // send request to the server
-  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
-  // then wait server response
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  if (result) {
-    assert(result->result() == "Hello");
-  }
-  else {
-    // error handle
-    std::cout<<result.error().msg()<<std::endl;
-  }
-}
-```
-
-We can call send_request multiple times to implement connection reuse:
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string echo(std::string);
-Lazy<void> example(coro_rpc_client& client) {
-  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
-  // First, send 10 requests consecutively
-  for (int i=0;i<10;++i) {
-    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
-  }
-  // Next, wait for all the requests to return
-  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
-  for (int i=0;i<10;++i) {
-    assert(results[i]->result() == std::to_string(i));
-  }
-  co_return;
-}
-```
-
-When sending data using the connection pool, we can also reuse a connection. To do this, you need to add the `coro_io::client_reuse_hint` parameter to instruct the connection pool to enable connection reuse. For more details, see the connection pool documentation. (TODO)
-
-```cpp
-auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
-    conf.url, pool_conf);
-auto ret = co_await pool->send_request(
-    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
-             return client.send_request<echo>("hello");
-           });
-if (ret.has_value()) {
-  auto result = co_await std::move(ret.value());
-  if (result.has_value()) {
-        assert(result.value()=="hello"); 
-  }
-}
-```
-
-### Attachment
-
-When using the `send_request` method, since multiple requests might be sent simultaneously, we should not call the `set_req_attachment` method to send an attachment to the server, nor should we call the `get_resp_attachment` and `release_resp_attachment` methods to get the attachment returned by the server.
-
-Instead, we can set the attachment when sending a request by calling the `send_request_with_attachment` function. Additionally, we can retrieve the attachment by calling the `->get_attachment()` and `->release_buffer()` methods of `async_rpc_result`.
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-int add(int a, int b);
-Lazy<std::string> example(coro_rpc_client& client) {
-  auto handler = co_await client.send_request_with_attachment<add>("Hello", 1, 2);
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  assert(result->result() == 3);
-  assert(result->get_attachment() == "Hello");
-  co_return std::move(result->release_buffer().resp_attachment_buf_);
-}
-```
-
-
-### Execution order
-
-When the called rpc function is a coroutine rpc function or a callback rpc function, the rpc requests may not necessarily be executed in order. The server might execute multiple rpc requests simultaneously.
-For example, suppose there is the following code:
-
-```cpp
-using namespace async_simple::coro;
-Lazy<void> sleep(int seconds) {
-  co_await coro_io::sleep(1s * seconds);  // Yield the coroutine here
-  co_return;
-}
-```
-
-Server registration and startup:
-```cpp
-using namespace coro_rpc;
-void start() {
-  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
-  server.register_handler<sleep>();
-  server.start();
-}
-```
-
-The client consecutively calls the sleep function twice on the same connection, sleeping for 2 seconds the first time and 1 second the second time.
-```cpp
-using namespace async_simple::coro;
-using namespace coro_rpc;
-Lazy<void> call() {
-  coro_rpc_client cli,cli2;
-  co_await cli.connect("localhost:8801");
-  co_await cli2.connect("localhost:8801");
-  auto handler1 = co_await cli.send_request<sleep>(2);
-  auto handler2 = co_await cli.send_request<sleep>(1);
-  auto handler3 = co_await cli2.send_request<sleep>(0);
-  handler2.start([](auto&&){
-    std::cout<<"handler2 return"<<std::endl;
-  });
-  handler3.start([](auto&&){
-   d::cout<<"handler3 return"<<std::endl;
-  });
-  co_await handler1;
-  std::cout<<"handler1 return"<<std::endl;
-}
-```
-Under normal circumstances, handler3 will return first, followed by handler2, and finally handler1. Although the server only has one IO thread for executing rpc functions, the coroutine function will yield the coroutine when calling `coro_io::sleep`, thus ensuring that other connections will not be blocked.
-
-### Socket Delayed Sending
-
-When using connection reuse, you can try setting the option `enable_tcp_no_delay` to `false`. This allows the underlying implementation to batch multiple small requests together for sending, thereby increasing throughput, but it may lead to increased latency.
-
-## Thread-safe
-
-For multiple coro_rpc_client instances, they do not interfere with each other and can be safely called in different threads respectively.
-
-When calling a single `coro_rpc_client` simultaneously in multiple threads, it is necessary to note that only some member functions are thread-safe, including `send_request()`, `close()`, `connect()`, `get_executor()`, `get_pipeline_size()`, `get_client_id()`, `get_config()`, etc. If the user has not called the `connect()` function again with an endpoint or hostname, then the `get_port()` and `get_host()` functions are also thread-safe.
-
-It is important to note that the `call`, `get_resp_attachment`, `set_req_attachment`, `release_resp_attachment`, and `init_config` functions are not thread-safe and must not be called by multiple threads simultaneously. In this case, only `send_request` can be used for multiple threads to make concurrent requests over a single connection.
-
-# coro_rpc Performance Testing
-First, compile the coro_rpc benchmark and then execute the `bench` command-line tool. The command-line options are as follows:
-```
-options:
-  -u, --url                   URL (string [=0.0.0.0:9000])
-  -s, --send_data_len         Send data length (unsigned long [=8388608])
-  -c, --client_concurrency    Total number of clients (unsigned int [=0])
-  -m, --max_request_count     Max request count (unsigned long [=100000000])
-  -p, --port                  Server port (unsigned short [=9000])
-  -r, --resp_len              Response data length (unsigned long [=13])
-  -b, --buffer_size           Buffer size (unsigned int [=262144])
-  -o, --log_level             Log level. Severity::INFO=1 (default), WARN is 4, etc. (int [=1])
-  -i, --enable_ib             Enable ibverbs (RDMA) (bool [=1])
-  -d, --duration              Duration in seconds (unsigned int [=100000])
-  -?, --help                  Print this message
-```
-
-Server-side command:
-`./bench -p 9004 -r 13 -o 5`
-
-Meaning: Start the server, set the response data length to 13, and set the log level to error (the log levels correspond to those in easylog).
-
-Client-side command:
-`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
-
-Meaning: Start 100 clients for stress testing, sending 8MB of data per request, with the log level set to error, and a duration of 30 seconds.
-
-If user install ibverbs environment, ibverbs is enabled default. To test only TCP, add the flag `-i 0`.
-
-After the performance test completes, it will output QPS, throughput, and latency data. The test results will look similar to this:
-```
-# Benchmark result
-avg qps 2757 and throughput:185.04 Gb/s in duration 30
-# HELP Latency(us) of rpc call help
-# TYPE Latency(us) of rpc call summary
-rpc call latency(us){quantile="0.500000"} 3616.000000
-rpc call latency(us){quantile="0.900000"} 3712.000000
-rpc call latency(us){quantile="0.950000"} 3776.000000
-rpc call latency(us){quantile="0.990000"} 3872.000000
-rpc call latency(us)_sum 298707968.000000
-rpc call latency(us)_count 82761
+# Introduction to coro_rpc Client
+
+## Base Usage
+
+class `coro_rpc::coro_rpc_client` is the client side of coro_rpc, allowing users to send RPC requests to the server. 
+
+Below, we will demonstrate the basic usage of rpc_client.
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+int add(int a,int b);
+Lazy<void> example() {
+  coro_rpc_client client;
+  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
+  if (ec) { /*check if connection error*/
+    std::cout<<ec.message()<<std::endl;
+    co_return;
+  }
+  rpc_result result = co_await client.call<add>(1,2);
+  /*rpc_result is type of expected<T,rpc_error>, which T is rpc return type*/
+  if (!result.has_value()) {
+    /*call result.error() to get rpc error message*/
+    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
+    co_return;
+  }
+  assert(result.value()==3); /*call result.value() to  get rpc return type*/
+}
+```
+
+You can use the `set_req_attachment` function to set the attachment for the current request. This is a piece of binary data that will be sent directly to the client without serialization. Similarly, you can also use `get_resp_attachment()` and `release_resp_attachment()` to retrieve the attachment returned by the RPC request.
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+void attachment_echo() {
+  auto ctx=coro_rpc::get_context();
+  ctx->set_resp_attachment(ctx->get_req_attachment());
+}
+Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
+  client.set_req_attachment(attachment);
+  rpc_result result = co_await client.call<attachment_echo>();
+  if (result.has_value()) {
+    assert(result.get_resp_attachment()==attachment);
+    co_return std::move(result.release_resp_attachment());
+  }
+  co_return "";
+}
+```
+
+By default, the RPC client will wait for 5 seconds after sending a request/establishing a connection. If no response is received after 5 seconds, it will return a timeout error. Users can also customize the wait duration by calling the `call_for` function.
+
+```cpp
+client.connect("127.0.0.1:9001", std::chrono::seconds{10});
+auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
+assert(result.value() == 3);
+```
+
+The duration can be any `std::chrono::duration` type, common examples include `std::chrono::seconds` and `std::chrono::milliseconds`. Notably, if the duration is set to zero, it indicates that the function call will never time out.
+
+## SSL support
+
+coro_rpc supports using OpenSSL to encrypt connections. After installing OpenSSL and importing yalantinglibs into your project with CMake's `find_package` or `fetch_content`, you can enable SSL support by setting the CMake option YLT_ENABLE_SSL=ON. Alternatively, you might manually add the YLT_ENABLE_SSL macro and manually link to OpenSSL.
+
+Once SSL support has been enabled, users can invoke the `init_ssl` function before establishing a connection to the server. This will create an encrypted link between the client and the server. It’s important to note that the coro_rpc server must also be compiled with SSL support enabled, and the `init_ssl` method must be called to enable SSL support before starting the server.
+
+For one -way SSL authentication(server authentication only),you can use the `init_ssl` function before establishing a connection:The first parameter is the base path where the SSL certificates are located, and the second parameter is the CA certificate filename for verifying the server.
+
+Server-side configuration:
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "";  // Empty for one-way authentication
+ssl_conf.enable_client_verify = false;  // Disable client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+Mutual SSL Authentication For mutual SSL authentication(both client and server authentication),the client needs to provide its own certificate :
+
+```cpp
+    // Client-side mutual authentication
+    client.init_ssl("./",  // Base path
+                    "ca.crt",  // CA certificate for server verification
+                    "client.crt",  // Client certificate
+                    "client.key",  // Client private key
+                    "127.0.0.1"  // Server hostname for SNI
+    );
+```
+
+Server-side configuration for mutual authentication:
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "ca.crt";  // CA certificate for verifying clients
+ssl_conf.enable_client_verify = true;  // Enable mandatory client certificate verification
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+**Important Notes**:
+- The `enable_client_verify` flag enables mandatory client certificate verification
+- When mutual authentication is enabled, clients must provide a valid certificate signed by the CA specified in `ca_cert_file`
+- The hostname parameter must match the Common Name (CN) in the server certificate
+
+We also support NTLS if you enable it by CMAKE OPTION `YLT_ENABLE_NTLS`.
+
+## Conversion and compile-time checking of RPC parameters
+
+coro_rpc will perform compile-time checks on the validity of arguments during invocation. For example, for the following rpc function:
+
+```cpp
+inline std::string echo(std::string str) { return str; }
+```
+
+Next, when the current client invokes the rpc function:
+
+```cpp
+client.call<echo>(42); // Parameter does not match, compilation error
+client.call<echo>(); // Missing parameter, compilation error
+client.call<echo>("", 0); // Extra parameters, compilation error
+client.call<echo>("hello, coro_rpc"); // The string literal can be converted to std::string, compilation succeeds
+```
+
+## Connection Options
+
+The `coro_rpc_client` provides an `init_config` function to configure connection options. The code below lists all configurable options, which are optional with default values.
+
+```cpp
+using namespace coro_rpc;
+using namespace std::chrono;
+void set_config(coro_rpc_client& client) {
+  uint64_t client_id;
+  std::chrono::milliseconds connect_timeout_duration;
+  std::chrono::milliseconds request_timeout_duration;
+  std::string host;
+  std::string port;
+  std::string local_ip;
+  client.init_config(config{
+    .connect_timeout_duration = 5s, // Connection timeout duration
+    .request_timeout_duration = 5s, // Request timeout duration
+    .host = "localhost", // Server hostname
+    .port = "9001", // Server port
+    .local_ip = "", // Local IP address used to specify the local communication interface
+    .socket_config=std::variant<tcp_config,
+                 tcp_with_ssl_config,
+                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // Specify transport protocol and its configuration. Supported protocols: TCP, SSL over TCP, RDMA
+  });
+}
+```
+
+### RDMA Socket Configuration
+
+The configuration for IBVerbs socket protocol is shown below:
+
+```cpp
+struct ib_socket_t::config_t {
+  uint32_t cq_size = 128; // Maximum length of event notification queue
+  uint32_t recv_buffer_cnt = 8;                 // Number of buffers pre-submitted to receive queue. Each buffer defaults to 256KB, so a RDMA connection occupies 8MB memory immediately after establishment. More pending receive data will result in more buffers in the queue, up to max_recv_wr*buffer_size (where buffer_size is configured in buffer_pool). If upper layer doesn't consume data, sender will receive RNR (Receiver Not Ready) errors and retry continuously.
+  uint32_t send_buffer_cnt = 4;                 // default send buffer queue max size,
+  ibv_qp_type qp_type = IBV_QPT_RC;             // Default QP type
+  ibv_qp_cap cap = {.max_send_wr = 32,           // Maximum send queue length
+                    .max_recv_wr = 32,          // Maximum receive queue length
+                    .max_send_sge = 3,          // Maximum send scatter/gather elements. Only 1 needed without inline data. Use 3 segments when using inline data (default supports 3 scattered addresses)
+                    .max_recv_sge = 1,          // Maximum receive scatter/gather elements. 1 suffices with current buffer configuration
+                    .max_inline_data = 256};    // If packet size < inline data threshold and NIC supports it, small packets bypass buffer copy and go directly to NIC
+  std::shared_ptr<coro_io::ib_device_t> device; // Underlying IB device for RPC. Defaults to first device in list
+};
+```
+
+Simple RDMA activation examples:
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv(); // Use default configuration
+  cli.init_ibv({.recv_buffer_cnt=8}); // Use custom configuration
+```
+
+RDMA activation through config:
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
+```
+
+#### RDMA Device Configuration
+
+The `ib_device_t` manages the connection context and buffers required during the ibverbs transmission process. By default, it uses the global device `coro_io::get_global_ib_device()`, but users can also specify their own device.
+
+By modifying the configuration of `ib_device_t`, users can assign different network interfaces to RPC connections and use separate buffers.
+
+1. Modify the default device configuration
+```cpp
+  // The configuration only takes effect on the first invocation
+  coro_io::get_global_ib_device({ 
+    .buffer_pool_config = {
+      .buffer_size = 256 * 1024,  // Buffer size
+      .max_memory_usage = 4 * 1024 * 1024, // Max memory usage (allocation fails beyond this limit)
+      .memory_usage_recorder = nullptr; // nullopt means that memory usage across different devices will be counted together. If you want the memory pool to have independent memory usage tracking, you should assign a non-null std::shared_ptr<std::atomic<std::size_t>> as the recorder.
+      .idle_timeout = 5s // Buffers unused for this duration will be reclaimed
+  }
+  });
+  // ...
+```
+
+      2. Specify the RDMA NIC to use when initializing the connection
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
+  });
+```
+
+      3. Create and use your own `ib_device_t`
+```cpp
+  auto dev = coro_io::ib_device_t::create({
+      .dev_name = "",  // If dev_name is empty, the first device in the device list will be used.
+      .port = 1,       // Manually specify the NIC port number.
+           .use_best_gid_index = true,  // Automatically find the best GID index for this device.
+      .gid_index = 0,   // Manually specify the GID index; takes effect when automatic lookup is disabled or fails.
+           .buffer_pool_config = {
+               // ...
+      }
+  });
+```
+
+      4. Query all currently successfully registered RDMA global devices
+```cpp
+      // Get all devices
+      auto devices = coro_io::g_ib_device_manager();
+  for (auto &dev: devices.get_dev_list()) {
+    std::cout << "name:" << dev.first;
+    // dev.second is a global std::shared_ptr<ib_device_t>
+  }
+```
+
+## Calling Model
+
+Each `coro_rpc_client` is bound to a specific IO thread. By default, it selects a connection via round-robin from the global IO thread pool. Users can also manually bind it to a specific IO thread.
+
+```cpp
+auto executor=coro_io::get_global_executor();
+coro_rpc_client client(executor),client2(executor);
+  // Both clients are bound to the same IO thread.
+```
+
+Each time a coroutine-based IO task is initiated (such as `connect`, `call`, `send_request`), the client internally submits the IO event to the operating system. When the IO event is completed, the coroutine is then resumed on the bound IO thread to continue execution. For example, in the following code, the task switches to the IO thread for execution after calling connect.
+
+```cpp
+/*run in thread 1*/
+coro_rpc_client cli;
+co_await cli.connect("localhost:9001");
+/*run in thread 2*/
+do_something();
+```
+
+## Connection Pool and Load Balancing
+
+`coro_io` offers a connection pool `client_pool` and a load balancer `channel`. Users can manage `coro_rpc`/`coro_http` connections through the `client_pool`, and can use `channel` to achieve load balancing among multiple hosts. For more details, please refer to the documentation of `coro_io`.
+
+## Connection Reuse
+
+The `coro_rpc_client` can achieve connection reuse through the `send_request` function. This function is thread-safe, allowing multiple threads to call the `send_request` method on the same client concurrently. The return value of the function is `Lazy<Lazy<async_rpc_result<T>>>`. The first `co_await` waits for the request to be sent, and the second `co_await` waits for the rpc result to return.
+
+
+Connection reuse allows us to reduce the number of connections under high concurrency, eliminating the need to create new connections. It also improves the throughput of each connection.
+
+Here's a simple example code snippet:
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string_view echo(std::string_view);
+Lazy<void> example(coro_rpc_client& client) {
+  // send request to the server
+  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
+  // then wait server response
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  if (result) {
+    assert(result->result() == "Hello");
+  }
+  else {
+    // error handle
+    std::cout<<result.error().msg()<<std::endl;
+  }
+}
+```
+
+We can call send_request multiple times to implement connection reuse:
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string echo(std::string);
+Lazy<void> example(coro_rpc_client& client) {
+  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
+  // First, send 10 requests consecutively
+  for (int i=0;i<10;++i) {
+    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
+  }
+  // Next, wait for all the requests to return
+  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
+  for (int i=0;i<10;++i) {
+    assert(results[i]->result() == std::to_string(i));
+  }
+  co_return;
+}
+```
+
+When sending data using the connection pool, we can also reuse a connection. To do this, you need to add the `coro_io::client_reuse_hint` parameter to instruct the connection pool to enable connection reuse. For more details, see the connection pool documentation. (TODO)
+
+```cpp
+auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
+    conf.url, pool_conf);
+auto ret = co_await pool->send_request(
+    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
+             return client.send_request<echo>("hello");
+           });
+if (ret.has_value()) {
+  auto result = co_await std::move(ret.value());
+  if (result.has_value()) {
+        assert(result.value()=="hello"); 
+  }
+}
+```
+
+### Attachment
+
+When using the `send_request` method, since multiple requests might be sent simultaneously, we should not call the `set_req_attachment` method to send an attachment to the server, nor should we call the `get_resp_attachment` and `release_resp_attachment` methods to get the attachment returned by the server.
+
+Instead, we can set the attachment when sending a request by calling the `send_request_with_attachment` function. Additionally, we can retrieve the attachment by calling the `->get_attachment()` and `->release_buffer()` methods of `async_rpc_result`.
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+int add(int a, int b);
+Lazy<std::string> example(coro_rpc_client& client) {
+  auto handler = co_await client.send_request_with_attachment<add>("Hello", 1, 2);
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  assert(result->result() == 3);
+  assert(result->get_attachment() == "Hello");
+  co_return std::move(result->release_buffer().resp_attachment_buf_);
+}
+```
+
+
+### Execution order
+
+When the called rpc function is a coroutine rpc function or a callback rpc function, the rpc requests may not necessarily be executed in order. The server might execute multiple rpc requests simultaneously.
+For example, suppose there is the following code:
+
+```cpp
+using namespace async_simple::coro;
+Lazy<void> sleep(int seconds) {
+  co_await coro_io::sleep(1s * seconds);  // Yield the coroutine here
+  co_return;
+}
+```
+
+Server registration and startup:
+```cpp
+using namespace coro_rpc;
+void start() {
+  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
+  server.register_handler<sleep>();
+  server.start();
+}
+```
+
+The client consecutively calls the sleep function twice on the same connection, sleeping for 2 seconds the first time and 1 second the second time.
+```cpp
+using namespace async_simple::coro;
+using namespace coro_rpc;
+Lazy<void> call() {
+  coro_rpc_client cli,cli2;
+  co_await cli.connect("localhost:8801");
+  co_await cli2.connect("localhost:8801");
+  auto handler1 = co_await cli.send_request<sleep>(2);
+  auto handler2 = co_await cli.send_request<sleep>(1);
+  auto handler3 = co_await cli2.send_request<sleep>(0);
+  handler2.start([](auto&&){
+    std::cout<<"handler2 return"<<std::endl;
+  });
+  handler3.start([](auto&&){
+   d::cout<<"handler3 return"<<std::endl;
+  });
+  co_await handler1;
+  std::cout<<"handler1 return"<<std::endl;
+}
+```
+Under normal circumstances, handler3 will return first, followed by handler2, and finally handler1. Although the server only has one IO thread for executing rpc functions, the coroutine function will yield the coroutine when calling `coro_io::sleep`, thus ensuring that other connections will not be blocked.
+
+### Socket Delayed Sending
+
+When using connection reuse, you can try setting the option `enable_tcp_no_delay` to `false`. This allows the underlying implementation to batch multiple small requests together for sending, thereby increasing throughput, but it may lead to increased latency.
+
+## Thread-safe
+
+For multiple coro_rpc_client instances, they do not interfere with each other and can be safely called in different threads respectively.
+
+When calling a single `coro_rpc_client` simultaneously in multiple threads, it is necessary to note that only some member functions are thread-safe, including `send_request()`, `close()`, `connect()`, `get_executor()`, `get_pipeline_size()`, `get_client_id()`, `get_config()`, etc. If the user has not called the `connect()` function again with an endpoint or hostname, then the `get_port()` and `get_host()` functions are also thread-safe.
+
+It is important to note that the `call`, `get_resp_attachment`, `set_req_attachment`, `release_resp_attachment`, and `init_config` functions are not thread-safe and must not be called by multiple threads simultaneously. In this case, only `send_request` can be used for multiple threads to make concurrent requests over a single connection.
+
+# coro_rpc Performance Testing
+First, compile the coro_rpc benchmark and then execute the `bench` command-line tool. The command-line options are as follows:
+```
+options:
+  -u, --url                   URL (string [=0.0.0.0:9000])
+  -s, --send_data_len         Send data length (unsigned long [=8388608])
+  -c, --client_concurrency    Total number of clients (unsigned int [=0])
+  -m, --max_request_count     Max request count (unsigned long [=100000000])
+  -p, --port                  Server port (unsigned short [=9000])
+  -r, --resp_len              Response data length (unsigned long [=13])
+  -b, --buffer_size           Buffer size (unsigned int [=262144])
+  -o, --log_level             Log level. Severity::INFO=1 (default), WARN is 4, etc. (int [=1])
+  -i, --enable_ib             Enable ibverbs (RDMA) (bool [=1])
+  -d, --duration              Duration in seconds (unsigned int [=100000])
+  -?, --help                  Print this message
+```
+
+Server-side command:
+`./bench -p 9004 -r 13 -o 5`
+
+Meaning: Start the server, set the response data length to 13, and set the log level to error (the log levels correspond to those in easylog).
+
+Client-side command:
+`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
+
+Meaning: Start 100 clients for stress testing, sending 8MB of data per request, with the log level set to error, and a duration of 30 seconds.
+
+If user install ibverbs environment, ibverbs is enabled default. To test only TCP, add the flag `-i 0`.
+
+After the performance test completes, it will output QPS, throughput, and latency data. The test results will look similar to this:
+```
+# Benchmark result
+avg qps 2757 and throughput:185.04 Gb/s in duration 30
+# HELP Latency(us) of rpc call help
+# TYPE Latency(us) of rpc call summary
+rpc call latency(us){quantile="0.500000"} 3616.000000
+rpc call latency(us){quantile="0.900000"} 3712.000000
+rpc call latency(us){quantile="0.950000"} 3776.000000
+rpc call latency(us){quantile="0.990000"} 3872.000000
+rpc call latency(us)_sum 298707968.000000
+rpc call latency(us)_count 82761
 ```

-# coro_rpc客户端介绍
-
-## 基本使用
-
-类`coro_rpc::coro_rpc_client`是coro_rpc的客户端，用户可以通过它向服务器发送rpc请求。
-
-下面我们展示rpc_client的基本使用方法。
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-int add(int a,int b);
-Lazy<void> example() {
-  coro_rpc_client client;
-  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
-  if (ec) { /*判断连接是否出错*/
-    std::cout<<ec.message()<<std::endl;
-    co_return;
-  }
-  rpc_result result = co_await client.call<add>(1,2);
-  /*rpc_result是一个expected<T,rpc_error>类型，其中T为rpc返回值*/
-  if (!result.has_value()) {
-    /*调用result.error()获取rpc错误信息*/
-    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
-    co_return;
-  }
-  assert(result.value()==3); /*调用result.value()获取rpc返回值*/
-}
-```
-
-我们可以通过`set_req_attachment`函数设置本次请求的attachment，这是一段不会经过序列化直接发送给客户端的二进制数据。同样的，我们也可以使用`get_resp_attachment()`和`release_resp_attachment()`来获取rpc请求返回的attachment。
-
-```cpp
-using namespace async_simple;
-using namespace coro_rpc;
-void attachment_echo() {
-  auto ctx=coro_rpc::get_context();
-  ctx->set_resp_attachment(ctx->get_req_attachment());
-}
-Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
-  client.set_req_attachment(attachment);
-  rpc_result result = co_await client.call<attachment_echo>();
-  if (result.has_value()) {
-    assert(result.get_resp_attachment()==attachment);
-    co_return std::move(result.release_resp_attachment());
-  }
-  co_return "";
-}
-```
-
-默认情况下，rpc客户端发送请求/建立连接后会等待5秒，如果5秒后仍未收到响应，则会返回超时错误。
-用户也可以通过调用`call_for`函数自定义等待的时长。
-
-```cpp
-client.connect("127.0.0.1:9001", std::chrono::seconds{10});
-auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
-assert(result.value() == 3);
-```
-
-时长可以是任一的`std::chrono::duration`类型，常见的如`std::chrono::seconds`,`std::chrono::millseconds`。
-特别的，如果时长为0，代表该函数调用永远也不会超时。
-
-## SSL支持
-
-coro_rpc支持使用openssl对连接进行加密。在安装openssl并使用cmake find_package/fetch_content 将yalantinglibs导入到你的工程后，可以打开cmake选项`YLT_ENABLE_SSL=ON`启用ssl支持。或者，你也可以手动添加宏`YLT_ENABLE_SSL`并手动链接openssl。
-
-当启用ssl支持后，用户可以调用`init_ssl`函数，然后再连接到服务器。这会使得客户端与服务器之间建立加密的链接。需要注意的是，coro_rpc服务端在编译时也必须启用ssl支持，并且在启动服务器之前也需要调用`init_ssl`方法来启用SSL支持。
-
-```cpp
-client.init_ssl("./","server.crt");
-```
-
-第一个字符串代表SSL证书所在的基本路径，第二个字符串代表SSL证书相对于基本路径的相对路径。
-
-当建立连接时，客户端会使用该证书校验服务端发来的证书，以避免中间人攻击。因此，客户端必须持有服务端使用的证书或其根证书。
-
-我们同样支持国密NTLS。你需要开启CMAKE选项`YLT_ENABLE_NTLS`。
-
-## RPC参数的转换与编译期检查
-
-coro_rpc会在调用的时候对参数的合法性做编译期检查，比如，对于如下rpc函数：
-
-```cpp
-inline std::string echo(std::string str) { return str; }
-```
-
-接下来，当前client调用rpc函数时：
-
-```cpp
-client.call<echo>(42);// The argument does not match, a compilation error occurs.
-client.call<echo>();// Missing argument, compilation error occurs.
-client.call<echo>("", 0);// There are too many arguments, a compilation error occurs.
-client.call<echo>("hello, coro_rpc");// The string literal can be converted to std::string, compilation succeeds.
-```
-
-## 连接选项
-
-coro_rpc_client提供了`init_config`函数，用于配置连接选项。下面这份代码列出了可配置的选项。这些选项默认均可以不填写。
-
-```cpp
-using namespace coro_rpc;
-using namespace std::chrono;
-void set_config(coro_rpc_client& client) {
-  uint64_t client_id;
-  std::chrono::milliseconds connect_timeout_duration;
-  std::chrono::milliseconds request_timeout_duration;
-  std::string host;
-  std::string port;
-  std::string local_ip;
-  client.init_config(config{
-    .connect_timeout_duration = 5s, // 连接的超时时间
-    .request_timeout_duration = 5s, // 请求超时时间
-    .host = "localhost", // 服务器域名
-    .port = "9001", // 服务器端口
-    .local_ip = "", // 本地ip，用于指定本地通信的ip地址。
-    .socket_config=std::variant<tcp_config,
-                 tcp_with_ssl_config,
-                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // 指定底层的协议及其底层配置，目前支持tcp, ssl over tcp, rdma三种协议。
-  });
-}
-```
-
-
-### rdma配置
-
-ibverbs协议的配置如下：
-```cpp
-struct ib_socket_t::config_t {
-  uint32_t cq_size = 128; // 事件通知队列的最大长度
-  uint32_t recv_buffer_cnt = 8;                 // 默认提交到接受队列的缓冲数目，一个缓冲区默认256KB。积压的接收数据越多，队列中的缓冲区也会越多，最多可以缓冲max_recv_wr*buffer_size这么多的数据(buffer_size为buffer_pool配置的缓冲区大小），此后如果上层仍不消费数据，则发送端会收到rnr错误，不断重试并等待对端消费。
-  uint32_t send_buffer_cnt = 4;                 // 默认的发送缓冲区队列长度上限。代表最多积压的发送缓冲区数目。
-  ibv_qp_type qp_type = IBV_QPT_RC;             // 默认的qp类型。
-  ibv_qp_cap cap = {.max_send_wr = 32,           // 发送队列的最大长度。
-                    .max_recv_wr = 32,          // 接受队列的最大长度
-                    .max_send_sge = 3,          // 发送的最大地址分段数，在不启用inline data时只需要1个。使用inline data时数据可能不经过拷贝直接从原始分段地址发送，因此设置为3段（默认支持3段分散地址）。
-                    .max_recv_sge = 1,          // 接受的最大地址分段数，目前的缓冲区配置下只需要1个即可。
-                    .max_inline_data = 256};    // 如果发送的数据包小于inline data，且底层网卡支持该设置，则小数据包不会被拷贝到缓冲中，而是直接交给网卡发送。
-  std::shared_ptr<coro_io::ib_device_t> device; // rpc使用的底层ib网卡。默认选择设备列表第一个网卡。
-};
-```
-
-可以通过下面的代码简单的启用rdma：
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv(); //使用默认配置
-  cli.init_ibv(ib_socket_t::config_t{}); //使用用户指定的配置
-```
-
-也可以在配置中启用rdma：
-
-```cpp
-  coro_rpc_client cli;
-  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
-```
-
-
-#### ib_device_t
-
-`ib_device_t`管理了ibverbs传输过程中需要使用到的连接上下文和缓冲区。默认使用全局设备`coro_io::get_global_ib_device()`，用户也可以指定使用自己的设备。
-
-通过修改ib_device_t的配置，可以给rpc连接配置不同的网卡，使用独立的缓冲区。
-
-1. 修改默认的设备配置
-```cpp
-  // 配置只有在第一次调用时才会生效
-  coro_io::get_global_ib_device({ 
-    .buffer_pool_config = {
-      .buffer_size = 256 * 1024,  // 缓冲区大小
-      .max_memory_usage = 4 * 1024 * 1024, // 最大内存使用量（超过此限制将分配失败）
-      .memory_usage_recorder = nullptr; // nullopt 表示不同设备的内存占用会被一起统计，如果想要让内存池具有独立的内存占用记录，请分配一个非空的std::shared_ptr<std::atomic<std::size_t>>作为记录
-      .idle_timeout = 5s // 空闲时间超过这个时长的缓冲区将被回收
-    }
-  }); 
-  // ...
-```
-
-2. 初始化连接时，指定需要使用的 RDMA 网卡
-```cpp
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
-  });
-```
-
-3. 创建并使用自己的 `ib_device_t`
-```cpp
-  auto dev = coro_io::ib_device_t::create({
-    .dev_name = "",  // 如果 dev_name 为 空，则会使用设备列表中的第一个设备
-    .port = 1, // 手动指定网卡port
-    .use_best_gid_index = true, // 自动查找该设备最佳的gid_index
-    .gid_index = 0, // 手动指定gid_index，当关闭自动查找或自动查找失败时生效
-    .buffer_pool_config = {
-      // ...
-    },
-  });
-  coro_rpc_client cli;
-  cli.init_ibv({
-    .device = dev
-  });
-```
-
-4. 查询当前所有成功注册的全局 RDMA 设备
-```cpp
-  // 获取所有设备
-  auto devices = coro_io::g_ib_device_manager();
-  for (auto &dev: devices.get_dev_list()) {
-    std::cout<<"name:"<<dev.first;
-    // dev.second 是一个全局的 std::shared_ptr<ib_device_t>
-  }
-```
-
-## 调用模型
-
-每一个`coro_rpc_client`都会绑定到某个IO线程上，默认通过轮转法从全局IO线程池中选择一个连接，用户也可以手动绑定到特定的IO线程上。
-
-```cpp
-auto executor=coro_io::get_global_executor();
-coro_rpc_client client(executor),client2(executor);
-// 两个客户端都被绑定到同一个io线程上
-```
-
-每次发起一个基于协程的IO任务（如`connect`,`call`,`send_request`），客户端内部会将IO事件提交给操作系统，当IO事件完成后，再将协程恢复到绑定的IO线程上继续执行。
-
-例如以下代码，调用connect之后任务将切换到IO线程执行。
-
-```cpp
-/*run in thread 1*/
-coro_rpc_client cli;
-co_await cli.connect("localhost:9001");
-/*run in thread 2*/
-do_something();
-```
-
-## 连接池与负载均衡
-
-`coro_io`提供了连接池`client_pool`与负载均衡器`channel`。用户可以通过连接池`client_pool`来管理`coro_rpc`/`coro_http`连接，可以使用`channel`实现多个host之间的负载均衡。具体请见`coro_io`的文档。
-
-## 连接复用
-
-`coro_rpc_client` 可以通过 `send_request`函数实现连接复用。该函数是线程安全的，允许多个线程同时调用同一个client的 `send_request`方法。该函数返回值为`Lazy<Lazy<async_rpc_result<T>>>`.
-
-
-连接复用允许我们在高并发下减少连接的个数，无需创建新的连接。同时也能提高每个连接的吞吐量。
-
-下面是一段简单的示例代码：
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string_view echo(std::string_view);
-Lazy<void> example(coro_rpc_client& client) {
-  //向服务器发送请求
-  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
-  async_rpc_result<std::string_view> result = co_await std::move(handler);
-  if (result) {
-    assert(result->result() == "Hello");
-  }
-  else {
-    // error handle
-    std::cout<<result.error().msg()<<std::endl;
-  }
-}
-```
-
-我们可以多次调用send_request实现连接复用：
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-std::string echo(std::string);
-Lazy<void> example(coro_rpc_client& client) {
-  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
-  // 准备发送10个请求
-  for (int i=0;i<10;++i) {
-    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
-  }
-  //接下来等待所有的请求返回
-  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
-  for (int i=0;i<10;++i) {
-    assert(results[i]->result() == std::to_string(i));
-  }
-  co_return;
-}
-```
-
-在使用连接池发送数据时，我们也可以复用连接，此时需要在添加`coro_io_client_reuse_hint`参数，提示连接池启用连接复用。详见连接池文档。（TODO）
-
-```cpp
-auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
-    conf.url, pool_conf);
-auto ret = co_await pool->send_request(
-    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
-        return client.send_request<echo>("hello");
-    });
-if (ret.has_value()) {
-    auto result = co_await std::move(ret.value());
-    if (result.has_value()) {
-        assert(result.value()=="hello"); 
-    }
-}
-```
-
-
-### Attachment
-
-使用`send_request`方法时，由于可能同时发送多个请求，因此我们不能调用`set_req_attachment`方法向服务器发送attachment，同样也不能调用`get_resp_attachment`和`release_resp_attachment`方法来获取服务器返回的attachment。
-
-我们可以通过调用`send_request_with_attachment`函数，在发送请求时设置attachment。我们也可以通过调用async_rpc_result的`->get_attachment()`方法和`->release_buffer()`方法来获取attachment。
-
-```cpp
-using namespace coro_rpc;
-using namespace async_simple::coro;
-int add(int a, int b);
-Lazy<std::string> example(coro_rpc_client& client) {
-  async_rpc_result<std::string_view> result = co_await co_await client.send_request_with_attachment<add>("Hello", 1, 2);
-  assert(result->result() == 3);
-  assert(result->get_attachment() == "Hello");
-  co_return std::move(result->release_buffer().resp_attachment_buf_);
-}
-```
-
-
-### 执行顺序
-
-当调用的rpc函数是协程rpc函数或回调rpc函数时，rpc请求不一定会按顺序执行，服务端可能会同时执行多个rpc请求。
-
-例如，假如有以下代码：
-
-```cpp
-using namespace async_simple::coro;
-Lazy<void> sleep(int seconds) {
-  co_await coro_io::sleep(1s * seconds);  // 在此处让出协程
-  co_return;
-}
-```
-
-服务器注册并启动：
-```cpp
-using namespace coro_rpc;
-void start() {
-  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
-  server.register_handler<sleep>();
-  server.start();
-}
-```
-
-客户端连续在同一个连接上调用两次sleep函数，第一次sleep2秒，第二次sleep1秒。
-```cpp
-using namespace async_simple::coro;
-using namespace coro_rpc;
-Lazy<void> call() {
-  coro_rpc_client cli,cli2;
-  co_await cli.connect("localhost:8801");
-  co_await cli2.connect("localhost:8801");
-  auto handler1 = co_await cli.send_request<sleep>(2);
-  auto handler2 = co_await cli.send_request<sleep>(1);
-  auto handler3 = co_await cli2.send_request<sleep>(0);
-  handler2.start([](auto&&){
-    std::cout<<"handler2 return"<<std::endl;
-  });
-  handler3.start([](auto&&){
-   d::cout<<"handler3 return"<<std::endl;
-  });
-  co_await handler1;
-  std::cout<<"handler1 return"<<std::endl;
-}
-```
-正常情况下handler3会先返回，随后是handler2，最后是handler1。尽管服务器只有一个IO线程用于执行rpc函数，但协程函数会在调用`coro_io::sleep`时让出该协程，从而保证其他连接不会被阻塞。
-
-### socket延迟发送
-
-当使用连接复用时，可以尝试将选项中的`enable_tcp_no_delay`设为`false`,这允许底层实现将多个小请求打包后一起发送，从而提高吞吐量，但是可能会导致延迟上升。
-
-## 线程安全
-
-对于多个coro_rpc_client实例，它们之间互不干扰，可以分别在不同的线程中安全的调用。
-
-单个coro_rpc_client在多个线程同时调用时需要注意，只有部分成员函数是线程安全的，包括`send_request()`,`close()`,`connect()`,`get_executor()`,`get_pipeline_size()`,`get_client_id()`,`get_config()`等。如果用户没有重新调用connect()函数并传入endpoint或hostname，那么`get_port()`,`get_host()`函数也是线程安全的。
-
-需要注意，`call`,`get_resp_attachment`,`set_req_attachment`,`release_resp_attachment`和`init_config`函数均不是线程安全的，禁止多个线程同时调用。此时只能使用`send_request`实现多个线程并发请求同一个连接。
-
-# coro_rpc 性能测试
-先编译coro_rpc 的bench再执行bench命令行，命令行详情：
-```
-options:
-  -u, --url                   url (string [=0.0.0.0:9000])
-  -s, --send_data_len         send data length (unsigned long [=8388608])

-  -?, --help                  print this message

-
-如果安装了ibverbs环境，则默认会启用ibverbs，如果希望只测试tcp则添加`-i 0`
-
-性能测试完成之后将输出qps，吞吐和latency数据，测试结果类似于：

+# coro_rpc客户端介绍
+
+## 基本使用
+
+类`coro_rpc::coro_rpc_client`是coro_rpc的客户端，用户可以通过它向服务器发送rpc请求。
+
+下面我们展示rpc_client的基本使用方法。
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+int add(int a,int b);
+Lazy<void> example() {
+  coro_rpc_client client;
+  coro_rpc::err_code ec = co_await client.connect("localhost:9001");
+  if (ec) { /*判断连接是否出错*/
+    std::cout<<ec.message()<<std::endl;
+    co_return;
+  }
+  rpc_result result = co_await client.call<add>(1,2);
+  /*rpc_result是一个expected<T,rpc_error>类型，其中T为rpc返回值*/
+  if (!result.has_value()) {
+    /*调用result.error()获取rpc错误信息*/
+    std::cout<<"error code:"<<result.error().val()<< ", error message:"<<result.error().msg()<<std::endl;
+    co_return;
+  }
+  assert(result.value()==3); /*调用result.value()获取rpc返回值*/
+}
+```
+
+我们可以通过`set_req_attachment`函数设置本次请求的attachment，这是一段不会经过序列化直接发送给客户端的二进制数据。同样的，我们也可以使用`get_resp_attachment()`和`release_resp_attachment()`来获取rpc请求返回的attachment。
+
+```cpp
+using namespace async_simple;
+using namespace coro_rpc;
+void attachment_echo() {
+  auto ctx=coro_rpc::get_context();
+  ctx->set_resp_attachment(ctx->get_req_attachment());
+}
+Lazy<std::string> example(coro_rpc_client& client, std::string_view attachment) {
+  client.set_req_attachment(attachment);
+  rpc_result result = co_await client.call<attachment_echo>();
+  if (result.has_value()) {
+    assert(result.get_resp_attachment()==attachment);
+    co_return std::move(result.release_resp_attachment());
+  }
+  co_return "";
+}
+```
+
+默认情况下，rpc客户端发送请求/建立连接后会等待5秒，如果5秒后仍未收到响应，则会返回超时错误。
+用户也可以通过调用`call_for`函数自定义等待的时长。
+
+```cpp
+client.connect("127.0.0.1:9001", std::chrono::seconds{10});
+auto result = co_await client.call_for<add>(std::chrono::seconds{10},1,2);
+assert(result.value() == 3);
+```
+
+时长可以是任一的`std::chrono::duration`类型，常见的如`std::chrono::seconds`,`std::chrono::millseconds`。
+特别的，如果时长为0，代表该函数调用永远也不会超时。
+
+## SSL支持
+
+coro_rpc支持使用openssl对连接进行加密。在安装openssl并使用cmake find_package/fetch_content 将yalantinglibs导入到你的工程后，可以打开cmake选项`YLT_ENABLE_SSL=ON`启用ssl支持。或者，你也可以手动添加宏`YLT_ENABLE_SSL`并手动链接openssl。
+
+当启用ssl支持后，用户可以调用`init_ssl`函数，然后再连接到服务器。这会使得客户端与服务器之间建立加密的链接。需要注意的是，coro_rpc服务端在编译时也必须启用ssl支持，并且在启动服务器之前也需要调用`init_ssl`方法来启用SSL支持。
+
+### 单向SSL认证
+
+单向SSL认证只验证服务器身份，客户端使用CA证书验证服务器：
+
+服务端配置：
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "";  // 单向认证为空
+ssl_conf.enable_client_verify = false;  // 不验证客户端证书
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+### 双向SSL认证（Mutual Authentication）
+
+双向SSL认证同时验证客户端和服务器身份，客户端需要提供自己的证书：
+
+客户端配置：
+
+```cpp
+    // 客户端双向认证
+    client.init_ssl("./",  // 证书路径
+                    "ca.crt",  // CA证书，用于验证服务器
+                    "client.crt",  // 客户端证书
+                    "client.key",  // 客户端私钥
+                    "127.0.0.1"  // 服务器主机名（SNI）
+    );
+```
+
+服务端配置：
+
+```cpp
+coro_rpc_server server(2, 9000);
+ssl_configure ssl_conf;
+ssl_conf.base_path = "./certs";
+ssl_conf.cert_file = "server.crt";
+ssl_conf.key_file = "server.key";
+ssl_conf.ca_cert_file = "ca.crt";  // CA证书，用于验证客户端
+ssl_conf.enable_client_verify = true;  // 启用客户端证书验证
+
+server.init_ssl(ssl_conf);
+server.register_handler<your_function>();
+server.start();
+```
+
+**重要说明**：
+- `enable_client_verify` 标志启用强制客户端证书验证
+- 启用双向认证后，客户端必须提供由 `ca_cert_file` 指定的CA签发的有效证书
+- 主机名参数必须与服务器证书中的通用名称（CN）或主题备用名称（SAN）匹配
+
+我们同样支持国密NTLS。你需要开启CMAKE选项`YLT_ENABLE_NTLS`。
+
+## RPC参数的转换与编译期检查
+
+coro_rpc会在调用的时候对参数的合法性做编译期检查，比如，对于如下rpc函数：
+
+```cpp
+inline std::string echo(std::string str) { return str; }
+```
+
+接下来，当前client调用rpc函数时：
+
+```cpp
+client.call<echo>(42);// The argument does not match, a compilation error occurs.
+client.call<echo>();// Missing argument, compilation error occurs.
+client.call<echo>("", 0);// There are too many arguments, a compilation error occurs.
+client.call<echo>("hello, coro_rpc");// The string literal can be converted to std::string, compilation succeeds.
+```
+
+## 连接选项
+
+coro_rpc_client提供了`init_config`函数，用于配置连接选项。下面这份代码列出了可配置的选项。这些选项默认均可以不填写。
+
+```cpp
+using namespace coro_rpc;
+using namespace std::chrono;
+void set_config(coro_rpc_client& client) {
+  uint64_t client_id;
+  std::chrono::milliseconds connect_timeout_duration;
+  std::chrono::milliseconds request_timeout_duration;
+  std::string host;
+  std::string port;
+  std::string local_ip;
+  client.init_config(config{
+    .connect_timeout_duration = 5s, // 连接的超时时间
+    .request_timeout_duration = 5s, // 请求超时时间
+    .host = "localhost", // 服务器域名
+    .port = "9001", // 服务器端口
+    .local_ip = "", // 本地ip，用于指定本地通信的ip地址。
+    .socket_config=std::variant<tcp_config,
+                 tcp_with_ssl_config,
+                 coro_io::ib_socket_t::config_t>{tcp_config{}}; // 指定底层的协议及其底层配置，目前支持tcp, ssl over tcp, rdma三种协议。
+  });
+}
+```
+
+
+### rdma配置
+
+ibverbs协议的配置如下：
+```cpp
+struct ib_socket_t::config_t {
+  uint32_t cq_size = 128; // 事件通知队列的最大长度
+  uint32_t recv_buffer_cnt = 8;                 // 默认提交到接受队列的缓冲数目，一个缓冲区默认256KB。积压的接收数据越多，队列中的缓冲区也会越多，最多可以缓冲max_recv_wr*buffer_size这么多的数据(buffer_size为buffer_pool配置的缓冲区大小），此后如果上层仍不消费数据，则发送端会收到rnr错误，不断重试并等待对端消费。
+  uint32_t send_buffer_cnt = 4;                 // 默认的发送缓冲区队列长度上限。代表最多积压的发送缓冲区数目。
+  ibv_qp_type qp_type = IBV_QPT_RC;             // 默认的qp类型。
+  ibv_qp_cap cap = {.max_send_wr = 32,           // 发送队列的最大长度。
+                    .max_recv_wr = 32,          // 接受队列的最大长度
+                    .max_send_sge = 3,          // 发送的最大地址分段数，在不启用inline data时只需要1个。使用inline data时数据可能不经过拷贝直接从原始分段地址发送，因此设置为3段（默认支持3段分散地址）。
+                    .max_recv_sge = 1,          // 接受的最大地址分段数，目前的缓冲区配置下只需要1个即可。
+                    .max_inline_data = 256};    // 如果发送的数据包小于inline data，且底层网卡支持该设置，则小数据包不会被拷贝到缓冲中，而是直接交给网卡发送。
+  std::shared_ptr<coro_io::ib_device_t> device; // rpc使用的底层ib网卡。默认选择设备列表第一个网卡。
+};
+```
+
+可以通过下面的代码简单的启用rdma：
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv(); //使用默认配置
+  cli.init_ibv(ib_socket_t::config_t{}); //使用用户指定的配置
+```
+
+也可以在配置中启用rdma：
+
+```cpp
+  coro_rpc_client cli;
+  cli.init_config(config{.socket_config=ib_socket_t::config_t{}})
+```
+
+
+#### ib_device_t
+
+`ib_device_t`管理了ibverbs传输过程中需要使用到的连接上下文和缓冲区。默认使用全局设备`coro_io::get_global_ib_device()`，用户也可以指定使用自己的设备。
+
+通过修改ib_device_t的配置，可以给rpc连接配置不同的网卡，使用独立的缓冲区。
+
+1. 修改默认的设备配置
+```cpp
+  // 配置只有在第一次调用时才会生效
+  coro_io::get_global_ib_device({ 
+    .buffer_pool_config = {
+      .buffer_size = 256 * 1024,  // 缓冲区大小
+      .max_memory_usage = 4 * 1024 * 1024, // 最大内存使用量（超过此限制将分配失败）
+      .memory_usage_recorder = nullptr; // nullopt 表示不同设备的内存占用会被一起统计，如果想要让内存池具有独立的内存占用记录，请分配一个非空的std::shared_ptr<std::atomic<std::size_t>>作为记录
+      .idle_timeout = 5s // 空闲时间超过这个时长的缓冲区将被回收
+    }
+  }); 
+  // ...
+```
+
+2. 初始化连接时，指定需要使用的 RDMA 网卡
+```cpp
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = coro_io::get_global_ib_device({.dev_name = "my_rmda_network_device_name"});
+  });
+```
+
+3. 创建并使用自己的 `ib_device_t`
+```cpp
+  auto dev = coro_io::ib_device_t::create({
+    .dev_name = "",  // 如果 dev_name 为 空，则会使用设备列表中的第一个设备
+    .port = 1, // 手动指定网卡port
+    .use_best_gid_index = true, // 自动查找该设备最佳的gid_index
+    .gid_index = 0, // 手动指定gid_index，当关闭自动查找或自动查找失败时生效
+    .buffer_pool_config = {
+      // ...
+    },
+  });
+  coro_rpc_client cli;
+  cli.init_ibv({
+    .device = dev
+  });
+```
+
+4. 查询当前所有成功注册的全局 RDMA 设备
+```cpp
+  // 获取所有设备
+  auto devices = coro_io::g_ib_device_manager();
+  for (auto &dev: devices.get_dev_list()) {
+    std::cout<<"name:"<<dev.first;
+    // dev.second 是一个全局的 std::shared_ptr<ib_device_t>
+  }
+```
+
+## 调用模型
+
+每一个`coro_rpc_client`都会绑定到某个IO线程上，默认通过轮转法从全局IO线程池中选择一个连接，用户也可以手动绑定到特定的IO线程上。
+
+```cpp
+auto executor=coro_io::get_global_executor();
+coro_rpc_client client(executor),client2(executor);
+// 两个客户端都被绑定到同一个io线程上
+```
+
+每次发起一个基于协程的IO任务（如`connect`,`call`,`send_request`），客户端内部会将IO事件提交给操作系统，当IO事件完成后，再将协程恢复到绑定的IO线程上继续执行。
+
+例如以下代码，调用connect之后任务将切换到IO线程执行。
+
+```cpp
+/*run in thread 1*/
+coro_rpc_client cli;
+co_await cli.connect("localhost:9001");
+/*run in thread 2*/
+do_something();
+```
+
+## 连接池与负载均衡
+
+`coro_io`提供了连接池`client_pool`与负载均衡器`channel`。用户可以通过连接池`client_pool`来管理`coro_rpc`/`coro_http`连接，可以使用`channel`实现多个host之间的负载均衡。具体请见`coro_io`的文档。
+
+## 连接复用
+
+`coro_rpc_client` 可以通过 `send_request`函数实现连接复用。该函数是线程安全的，允许多个线程同时调用同一个client的 `send_request`方法。该函数返回值为`Lazy<Lazy<async_rpc_result<T>>>`.
+
+
+连接复用允许我们在高并发下减少连接的个数，无需创建新的连接。同时也能提高每个连接的吞吐量。
+
+下面是一段简单的示例代码：
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string_view echo(std::string_view);
+Lazy<void> example(coro_rpc_client& client) {
+  //向服务器发送请求
+  Lazy<async_rpc_result<std::string_view>> handler = co_await client.send_request<echo>("Hello");
+  async_rpc_result<std::string_view> result = co_await std::move(handler);
+  if (result) {
+    assert(result->result() == "Hello");
+  }
+  else {
+    // error handle
+    std::cout<<result.error().msg()<<std::endl;
+  }
+}
+```
+
+我们可以多次调用send_request实现连接复用：
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+std::string echo(std::string);
+Lazy<void> example(coro_rpc_client& client) {
+  std::vector<Lazy<async_rpc_result<std::string>>> handlers;
+  // 准备发送10个请求
+  for (int i=0;i<10;++i) {
+    handlers.push_back(co_await client.send_request<echo>(std::to_string(i)));
+  }
+  //接下来等待所有的请求返回
+  std::vector<async_rpc_result<std::string>> results = co_await collectAll(std::move(handlers));
+  for (int i=0;i<10;++i) {
+    assert(results[i]->result() == std::to_string(i));
+  }
+  co_return;
+}
+```
+
+在使用连接池发送数据时，我们也可以复用连接，此时需要在添加`coro_io_client_reuse_hint`参数，提示连接池启用连接复用。详见连接池文档。（TODO）
+
+```cpp
+auto pool = coro_io::client_pool<coro_rpc::coro_rpc_client>::create(
+    conf.url, pool_conf);
+auto ret = co_await pool->send_request(
+    [&](coro_io::client_reuse_hint, coro_rpc::coro_rpc_client& client) {
+        return client.send_request<echo>("hello");
+    });
+if (ret.has_value()) {
+    auto result = co_await std::move(ret.value());
+    if (result.has_value()) {
+        assert(result.value()=="hello"); 
+    }
+}
+```
+
+
+### Attachment
+
+使用`send_request`方法时，由于可能同时发送多个请求，因此我们不能调用`set_req_attachment`方法向服务器发送attachment，同样也不能调用`get_resp_attachment`和`release_resp_attachment`方法来获取服务器返回的attachment。
+
+我们可以通过调用`send_request_with_attachment`函数，在发送请求时设置attachment。我们也可以通过调用async_rpc_result的`->get_attachment()`方法和`->release_buffer()`方法来获取attachment。
+
+```cpp
+using namespace coro_rpc;
+using namespace async_simple::coro;
+int add(int a, int b);
+Lazy<std::string> example(coro_rpc_client& client) {
+  async_rpc_result<std::string_view> result = co_await co_await client.send_request_with_attachment<add>("Hello", 1, 2);
+  assert(result->result() == 3);
+  assert(result->get_attachment() == "Hello");
+  co_return std::move(result->release_buffer().resp_attachment_buf_);
+}
+```
+
+
+### 执行顺序
+
+当调用的rpc函数是协程rpc函数或回调rpc函数时，rpc请求不一定会按顺序执行，服务端可能会同时执行多个rpc请求。
+
+例如，假如有以下代码：
+
+```cpp
+using namespace async_simple::coro;
+Lazy<void> sleep(int seconds) {
+  co_await coro_io::sleep(1s * seconds);  // 在此处让出协程
+  co_return;
+}
+```
+
+服务器注册并启动：
+```cpp
+using namespace coro_rpc;
+void start() {
+  coro_rpc_server server(/* thread = */1,/* port = */ 8801);
+  server.register_handler<sleep>();
+  server.start();
+}
+```
+
+客户端连续在同一个连接上调用两次sleep函数，第一次sleep2秒，第二次sleep1秒。
+```cpp
+using namespace async_simple::coro;
+using namespace coro_rpc;
+Lazy<void> call() {
+  coro_rpc_client cli,cli2;
+  co_await cli.connect("localhost:8801");
+  co_await cli2.connect("localhost:8801");
+  auto handler1 = co_await cli.send_request<sleep>(2);
+  auto handler2 = co_await cli.send_request<sleep>(1);
+  auto handler3 = co_await cli2.send_request<sleep>(0);
+  handler2.start([](auto&&){
+    std::cout<<"handler2 return"<<std::endl;
+  });
+  handler3.start([](auto&&){
+   d::cout<<"handler3 return"<<std::endl;
+  });
+  co_await handler1;
+  std::cout<<"handler1 return"<<std::endl;
+}
+```
+正常情况下handler3会先返回，随后是handler2，最后是handler1。尽管服务器只有一个IO线程用于执行rpc函数，但协程函数会在调用`coro_io::sleep`时让出该协程，从而保证其他连接不会被阻塞。
+
+### socket延迟发送
+
+当使用连接复用时，可以尝试将选项中的`enable_tcp_no_delay`设为`false`,这允许底层实现将多个小请求打包后一起发送，从而提高吞吐量，但是可能会导致延迟上升。
+
+## 线程安全
+
+对于多个coro_rpc_client实例，它们之间互不干扰，可以分别在不同的线程中安全的调用。
+
+单个coro_rpc_client在多个线程同时调用时需要注意，只有部分成员函数是线程安全的，包括`send_request()`,`close()`,`connect()`,`get_executor()`,`get_pipeline_size()`,`get_client_id()`,`get_config()`等。如果用户没有重新调用connect()函数并传入endpoint或hostname，那么`get_port()`,`get_host()`函数也是线程安全的。
+
+需要注意，`call`,`get_resp_attachment`,`set_req_attachment`,`release_resp_attachment`和`init_config`函数均不是线程安全的，禁止多个线程同时调用。此时只能使用`send_request`实现多个线程并发请求同一个连接。
+
+# coro_rpc 性能测试
+先编译coro_rpc 的bench再执行bench命令行，命令行详情：
+```
+options:
+  -u, --url                   url (string [=0.0.0.0:9000])
+  -s, --send_data_len         send data length (unsigned long [=8388608])
+  -c, --client_concurrency    total number of http clients (unsigned int [=0])
+  -m, --max_request_count     max request count (unsigned long [=100000000])
+  -p, --port                  server port (unsigned short [=9000])
+  -r, --resp_len              response data length (unsigned long [=13])
+  -b, --buffer_size           buffer size (unsigned int [=262144])
+  -o, --log_level             Severity::INFO 1 as default, WARN is 4 (int [=1])
+  -i, --enable_ib             enable ib (bool [=1])
+  -d, --duration              duration seconds (unsigned int [=100000])
+  -?, --help                  print this message
+```
+
+server侧命令行：
+`./bench -p 9004 -r 13 -o 5`
+
+含义：启动服务端，response的数据长度为13，日志级别为error(日志级别和easylog的日志级别对应)。
+
+client测命令行：
+`./bench -u 0.0.0.0:9004 -c 100 -s 8388608 -o 5 -d 30`
+
+含义：启动100个client去压测，每次请求发送8MB数据，日志级别为error，持续时间30秒。
+
+如果安装了ibverbs环境，则默认会启用ibverbs，如果希望只测试tcp则添加`-i 0`
+
+性能测试完成之后将输出qps，吞吐和latency数据，测试结果类似于：
+```
+# Benchmark result
+avg qps 2757 and throughput:185.04 Gb/s in duration 30
+# HELP Latency(us) of rpc call help
+# TYPE Latency(us) of rpc call summary
+rpc call latency(us){quantile="0.500000"} 3616.000000
+rpc call latency(us){quantile="0.900000"} 3712.000000
+rpc call latency(us){quantile="0.950000"} 3776.000000
+rpc call latency(us){quantile="0.990000"} 3872.000000
+rpc call latency(us)_sum 298707968.000000
+rpc call latency(us)_count 82761

Subject: [PATCH 32/38] fix: use separate mutual_ prefixed certs for mutual
 auth tests

- Restore all original upstream cert/key files unchanged
- Add mutual_ prefixed certs for mutual auth tests only
- mutual_fake.crt is self-signed (not by mutual CA) for negative testing
- Update test files to reference new mutual_ cert names

Subject: [PATCH 33/38] fix: restore main branch SSL certs and use server.crt
 for one-way auth tests

- Restore server.crt/key from main branch (self-signed certificates)
- Fix test code to use server.crt directly instead of ca.crt for verification
- Update line endings for dh512.pem, dhparam.pem, generate.txt
- Add server.csr from main branch

SSL one-way authentication now uses self-signed server.crt directly,
while mutual authentication tests continue using mutual_* prefixed certs.
