Examples of using authlib's httpx client asynchronously

Question

There are several examples here of using an httpx client instead of a requests based session with the popular oauth lib, authlib

However in those examples, they don't show how to properly open and close an async httpx session. See https://www.python-httpx.org/async/

When I try to use it as suggested, I get warnings either about the session not being closed:

UserWarning: Unclosed <authlib.integrations.httpx_client.oauth2_client.AsyncOAuth2Client object at 0x000001B6444BFEB0>. See https://www.python-httpx.org/async/#opening-and-closing-clients for details

And if I call twice, I get

RuntimeError: Event loop is closed

This makes complete sense to me, as the examples in authlibs docs aren't using a context manager for the async session

Answer 1

authlib's AsyncOAuth2Client inherits from httpx's AsyncClient, so you should be able to use the same methods given at https://www.python-httpx.org/async/#opening-and-closing-clients. So either something like:

async with authlib.integrations.httpx_client.oauth2_client.AsyncOAuth2Client() as client:
    ...

or:

client = authlib.integrations.httpx_client.oauth2_client.AsyncOAuth2Client()
...
await client.aclose()

Should allow you to open and close sessions as needed.
