Python httpx log all request headers

Question

How can I log all request headers of an httpx request? I use log level DEBUG nad response headers log fine but there are no request headers in the log. If it matters I'm using async api of httpx lib.

Answer 1

Use custom event hooks:

import httpx
import logging

logging.basicConfig(level=logging.DEBUG)
async def log_request(request):
    logging.debug(f"Request headers: {request.headers}")
async with httpx.AsyncClient(event_hooks={'request': [log_request]}) as client:
    response = await client.get('https://httpbin.org/get')
