Configure HTTPX_CLIENT_KWARGS in AsyncOAuth2Client while using Starlette OAuth

[Mark90]

Hi!

I'm using the Starlette OAuth client like this:

from authlib.integrations.starlette_client import OAuth

oauth_client = OAuth()

oauth_client.register(
    "my_app",
    server_metadata_url="http://example.com/.well-known/openid-configuration",
    client_id='my_client_id',
    client_secret='my_client_secret',
    request_token_params={"grant_type": "client_credentials"}
)

This client eventually uses the AsyncOAuth2Client from authlib/integrations/httpx_client/oauth2_client.py. There it initializes AsyncClient.__init__(self, **client_kwargs) which is from the httpx library.

Now I'm trying to configure one of the **client_kwargs, specifically the verify kwarg (which is present in HTTPX_CLIENT_KWARGS). I've spent a few hours trying, reading the source code, but I don't see a way to pass these kwargs through either OAuth() or OAuth().register().

For example I've tried these configurations:

oauth_client.register(
    "my_app",
    server_metadata_url="http://example.com/.well-known/openid-configuration",
    client_id='my_client_id',
    client_secret='my_client_secret',
    request_token_params={"grant_type": "client_credentials"}
    kwargs={ # <----
        "verify": verify,
        "client_kwargs": {"verify": verify, "client_kwargs": {"verify": verify}},
    },
)

To no avail - AsyncClient.__init__ call is done without verify.

Does anyone know if this is possible? As far as I can tell this is not documented, and there isn't a related usecase in the demo apps or unittests.

I'll start going through the code with a debugger, eventually I should find the answer and post it back here.

The answer turns out to be

oauth_client.register(
    "my_app",
    server_metadata_url="http://example.com/.well-known/openid-configuration",
    client_id='my_client_id',
    client_secret='my_client_secret',
    request_token_params={"grant_type": "client_credentials"},
    client_kwargs={"verify": verify}  # <---
)

I feel a bit stupid now :)
