Capturing Server TLS Certificates

[aaronst]

Is it possible to get the server TLS certificate for any given Response? aiohttp makes this possible with access to the asyncio.Transport, which has the .get_extra_info() method. It doesn't look like that's used in httpx though.

Great question yup. We need some docs around this.

Take a look at response.extensions['network_stream']. This exposes a get_extra_info(), which includes SSL info in some contexts.

The low-level httpcore package has some docs about this https://www.encode.io/httpcore/extensions/#network_stream which are also valid to httpx since the extensions are passed through.

Awesome yeah, I did end up finding this but forgot to come back here and answer. Thanks!
