Regarding the improvement of headless mode #1279
Description
Regarding the improvement of headless mode, currently when extracting xhr, the monitored url will be put into json data. Only when json output is turned on can the data be seen in the xhr_requests field, and there is only request data for the url but no response data for the url. This obviously does not meet the usage requirements. I think the xhr interface request should not be hidden in the json data but should be sent to the result separately. In addition, there are a large number of duplicate requests in go pageRouter.Start, which should be deduplicated here.
