Support HTTP/2 without TLS

See original GitHub issue

Would it be possible to force the httpx client to use HTTP/2 to communicate with the server without TLS?

I’m using it as

client = AsyncClient(http_versions=["HTTP/2"])

but it still (reasonably tho) uses HTTP/1.1.

Most of the clients are trying to negotiate the update to HTTP/2 over HTTP/1.1 before as well, which is desired behaviour, but it might be handy for easier development and/or debugging.

There’s hyper.HTTP20Connection that enforces h2, but it gets a bit out of sync from h2 itself.

Hi @indomirreg, I don’t we have plans in the near future to support this, certainly not pre 1.0. But I think we’re all in agreement this is something we could look into so I’m reopening this issue.

Ah, so the goal is to test the Uvicorn HTTP/2 implementation? 😄 Sounds exciting.

I think there’s not a pressing need otherwise to add support for unencrypted HTTP/2, and as you wrote it’s probably worth a different ticket spun up from this one.

If you all are OK with it I’ll close this, and open one about documenting usage of self-signed certificates. Thanks @gvbgduh!
