Override ":authority" via headers

[kb]

I deeped into docs and searched old issues, and cannot found a effective way to set custom headers. By the way, I also try to read source code but I thought it won't be useful at once, and it turns out right.

I used code below. My test server return 400 and log that client have sent out of pseudo headers when I try set header.

with niquests.Session() as s:
    # failed.
    # s.headers = {":authority": "a.b.com"}
    s.headers = {"host": "a.b.com"}
    s.quic_cache_layer.add_domain("192.168.87.77", 7443)
    r = s.get("https://192.168.87.77:7443/cool", verify=False)
    # failed as well
    # r = s.get("https://192.168.87.77:7443/cool", verify=False, headers={"host": "a.b.com"})
    print(r)

My test server was nginx/1.26.0, its error log looked like

2024/05/25 09:04:56 [info] 754638#0: *125 client sent out of order pseudo-headers while reading client request, client: 192.168.87.13, server: a.b.com, request: "GET /cool HTTP/3.0", host: "a.b.com"

First, we do not support setting :authority manually, at least, we did not intend to support it.
But the Host entry should work as-is, and later be converted accordingly.

There's two way we could do this:

A) Using the Host header

import niquests

if __name__ == "__main__":

    with niquests.Session() as s:
        s.quic_cache_layer.add_domain("192.168.87.77", 7443)
        r = s.get("https://192.168.87.77:7443/cool", headers={"host": "a.b.com"}, verify=False)

        print(r)

B) Using a custom resolver

import niquests

if __name__ == "__main__":

   with niquests.Session(resolver="in-memory://default/?hosts=a.b.com:192.168.87.77") as s:
       s.quic_cache_layer.add_domain("a.b.com", 7443)
       r = s.get("https://a.b.com:7443/cool", verify=False)

       print(r)

Something doesn't look right on our end for A. Your intuition did not fail you.
We are providing an immediate fix for this. Run pip install urllib3.future -U.

The documentation update is welcomed, if you are willing to submit a PR for it.
If the issue is fixed, feel free to close the issue.

Yes, it works! And thanks for your awesome reaction of bugfix.
