docker-credential-secretservice assumes needing to query by hostname not URL

[yarikoptic]

Relates to

• If failed to get credential - inform on what input, and use stdout if no stderr #221

which provides some versioning etc info.

I have

❯ docker-credential-secretservice list
{"https://index.docker.io/v1/":"repronimservices","workshop.dev.flywheel.io":"yarikoptic@gmail.com"}

with

❯ grep -v '^#' /etc/containers/registries.conf
[registries.search]
registries = ['docker.io']
❯ cat ~/.docker/config.json
{
	"auths": {
		"https://index.docker.io/v1/": {}
	},
	"credsStore": "secretservice",
	"experimental": "enabled"
}

and everything seems to work ok in general - I can docker login to switch to another user etc. But attempt to run a simple oras-py code fails since docker-credential-secretservice is provided the hostname (docker.io) and not URL.

https://github.com/docker/docker-credential-helpers?tab=readme-ov-file#development says that

get: Retrieves credentials from the keychain. The payload in the standard input is the raw value for the ServerURL.

so sounds like it expects "ServerURL"... so URL not hostname? Could/should both URL and hostname tried but is there a correspondence between the two somewhere?

FWIW, if I do echo "https://index.docker.io/v1/" | docker-credential-secretservice get | sed -e 's,https://index.docker.io/v1/,docker.io,g' | docker-credential-secretservice store, so to make secret service return a record

❯ echo "docker.io" | docker-credential-secretservice get
{"ServerURL":"docker.io","Username":"repronimservices","Secret":"...."}

script no longer fails to retrieve credential ...
