Description

Hi! First off, thank you so much for building and maintaining requests_oauth2client. It's great!

I'm debugging an UnknownTokenEndpointError right now, and my first instinct was to turn on requests_oauth2client's logging so that I could see the full HTTP requests and responses...but there isn't any logging yet. Any chance you might consider adding some? It'd be a huge help for debugging like this.

Thanks in advance!

Found how to enable logging at the requests level, that takes some of the pressure off here: https://requests.readthedocs.io/en/latest/api/#:~:text=be%20handled%20by-,configuring%20logging

Thanks for the feedback! I might add logging at some point, but PRs are welcome :)

If you get a UnknownTokenEndpointError , that means the AS sends back an error code that does not have a dedicated exception class. You can see that error and error_description in corresponding attributes of the error. I added most of the standard ones from https://www.iana.org/assignments/oauth-parameters/oauth-parameters.xhtml a while back, but some new ones probably have popped since then. I'll check that. Or it might be a non-standard error code.

You also have access to the Request and Response instances as attributes of that exception, e.g. like this:

try:
    oauth2client.client_credentials() # or whatever other way you send the token request
except EndpointError as exc:
    print(f"{exc.error}: {exc.description}")
    print(exc.response.status_code, exc.response.reason)
    for header,  value in exc.response.headers.items():
        print(f"{header}: {value}")
    print(exc.response.text)

Let me know if that helps you identify your issue.

Did you find which error code your AS was returning ? And is your issue solved?

Hi! I did figure this one out and get past it, but I don't remember the root cause, sorry.
