get server ip from response of httpx get

Question

As the title says, if I do resp=httpx.get(url) how do I get the IP from which the url was resolved?

There’s This question about how to do it with requests but the same methods don’t appear to exist in the httpx objects.

Answer 1

Empirically, you can do it with an exquisitely ugly incantation like as follows.

Do note that this involves digging into no less than 6 underscore-private attribute of the response stream, so it could stop working at any time when you upgrade httpx. (This worked for me with httpx 0.23.0.)

import httpx

with httpx.Client() as hc:
    r = hc.get("https://httpbin.org/get")
    peername = r.stream._stream._httpcore_stream._stream._connection._network_stream._sock.getpeername()
    print(r.json())
    print(peername)

This prints out

{'args': {}, 'headers': {'Accept': '*/*', 'Accept-Encoding': 'gzip, deflate', 'Host': 'httpbin.org', 'User-Agent': 'python-httpx/0.23.0', 'X-Amzn-Trace-Id': 'Root=...'}, 'origin': '....', 'url': 'https://httpbin.org/get'}

I was looking to solve the same problem. I was concerned about forward the compatibility of the "exquisitely ugly incantation" provided in the answer here. I’m using httpx with Trio, and realized I can use the Trio socket implementation to use an async version of sockets to answer this question.
see: https://trio.readthedocs.io/en/stable/reference-io.html#trio.socket.getaddrinfo

I posted this question to the httpx Q&A and got this answer: https://github.com/encode/httpx/discussions/2633#discussioncomment-5439764
In short, access to this information is provided through httpcore. There is an open issue to update the documentation.

import httpx

with httpx.Client() as client:
    with client.stream("GET", "https://httpbin.org/get") as response:
        network_stream = response.extensions["network_stream"]
        server_addr = network_stream.get_extra_info("server_addr")
        print(response.json())
        print(server_addr)
