One aiohttp Request Through an HTTP Proxy

For one asynchronous request through an unauthenticated HTTP proxy, keep the route on session.get(). Add aiohttp to the project if needed:

uv add aiohttp

Replace the documentation address below with your HTTP listener or a candidate from the HTTP proxy list. It must permit CONNECT to the HTTPS destination; a SOCKS-only endpoint needs a suitable connector instead of this proxy argument.

import asyncio
import aiohttp

async def main():
    timeout = aiohttp.ClientTimeout(total=15, connect=5)
    async with aiohttp.ClientSession(
        timeout=timeout,
        trust_env=False,
    ) as session:
        async with session.get(
            "https://example.com/",
            proxy="http://203.0.113.10:8080",
        ) as response:
            print(response.status)
            print((await response.text())[:200])

asyncio.run(main())

The request prints its HTTP status and the first 200 characters of the response text. A 403 or 429 remains an inspectable response here; call response.raise_for_status() if your application should turn unsuccessful statuses into exceptions. The async context managers close the session and response when their blocks finish, including on an exception.

The 15-second total budget covers the request operation. The 5-second connect budget includes waiting for an available pooled connection, so a busy pool can consume it before a new socket opens. This distinction matters when adapting the single call into concurrent checks.

trust_env=False keeps the shown route explicit. aiohttp does not discover proxy environment variables by default; exporting one in another terminal will not configure this call. Choose trust_env=True only when the process's inherited environment is the intended routing policy.
