How to use proxies with aiohttp

Which proxy works best with aiohttp?

For most scraping, Residential Lite is the cheapest way to get home IP addresses in the right country. Use Residential when you need a particular state or city, and Unlimited Datacenter for targets in the United States that do not block data centre addresses.

• Residentialfrom $3.52 per GB
• Residential Litefrom $0.96 per GB
• Unlimited Datacenterfrom $0.56 per hour

Proxy settings for aiohttp: host, port and login

A BooProxies plan gives you four things: a host, a port, a username and a password. These are the values for Residential; the username and password are on your plan page.

As one address:

http://USERNAME:PASSWORD@resi.proxies.boo:8080

The country and the session are chosen in the username, not in a separate setting. The generator on your plan page writes the username for you, and Targeting and sessions explains each part.

aiohttp proxy setup, step by step

1. Pass proxy= with each request.
2. To use many IP addresses at once, give each task its own session ID in the username.

aiohttp proxy example

Python

import asyncio
import aiohttp

async def main():
    async with aiohttp.ClientSession() as session:
        async with session.get("https://api.ipify.org", proxy="http://USERNAME:PASSWORD@resi.proxies.boo:8080") as r:
            print(await r.text())

asyncio.run(main())

Replace USERNAME and PASSWORD with the login from your plan page. The example asks an IP-check address, so the output is the address your request left from.

Rotating or sticky sessions for aiohttp?

For crawling many pages with aiohttp, leave the username without a session so every request leaves from a new IP address. For anything with steps that belong together, such as a login, a cart or a paginated search that sets cookies, add a session to the username so those requests share one address.

A sticky username looks like this:

USERNAME-country-us-time-600-session-a1b2c3d4

aiohttp proxy not working?

• aiohttp does not read SOCKS addresses itself. Install aiohttp-socks and use its ProxyConnector for port 1080.
• Hundreds of requests at once through one username is fine for rotating use. Add a limit with asyncio.Semaphore so the target site is not hammered.
• A 407 error means the username or password was not accepted. Copy both again from your plan page, and check that nothing added a space or cut the username short.
• If the IP address is in the wrong country, look at the username: the country code is part of it. More fixes.
