How to get tls version for the httpx Client request

[heysarthak]

i am following the below method

conn = httpx.Client(http2=True,http1=False,verify=ssl_contexts)
resp = conn.request("POST","https://{}:{}".format(serviceName,ip_port),data=data)

How can i get the tls version of the given request?

You might want to look at using the "trace" extension which will expose the SSLContext in the "connection.start_tls.started" event.

def log(event_name, info):
    print(event_name, info)

resp = conn.request("POST", "https://{}:{}".format(serviceName,ip_port), data=data, extensions={"trace": log})

Or you can inspect the network stream on the response instance...

resp.extensions["network_stream"].get_extra_info("ssl_object")

This solution may work if you use http11 because the network_stream extension is not currently supported by http2.

import httpx

conn = httpx.Client()
with conn.stream('GET', "https://www.google.com") as resp:
    stream = resp.extensions['network_stream']
    print(stream.get_extra_info('socket').cipher())

OUTPUT

('TLS_AES_256_GCM_SHA384', 'TLSv1.3', 256)
