Aiotor - a pool of proxies, shifting on each request

What?

using aiotor you can easily create a small pool of tor proxies so you can take advantage of having multiple circuits at your disposal and multiple ip addresses, while running just 1 process. It also brings a ClientSession, which is the ClientSession from aiohttp with a small modification: it shifts proxies at every request.

Does it work for requests package? and urllib? and plain sockets ?

yes! aitor.Pool() is a context manager which, while in context, patches the low level socket library, so it's usage is easy and compatible for almost all setups/libraries.

Cleaning up

Pool will automatically cleanup the temp folder after your program ends. the folder is needed for tor to store circuit and consensus data. if you specify a folder explicitly, like Pool(user_data_dir="c:\some\folder\tordata"), it is assumed you want a dedicated folder. in that case cleanup will not happen. using a dedicated folder will greatly improve loading time on next runs.

It is blocking!

only once! aiotor should ideally be started on your mainthread. it will block to bootstrap the tor connections, and this only happens once during the full lifecycle of your program. while subprocesses are supported by asyncio, it would render useless as proxies can't be used anyway, until initialization is finished. It also brings a lot of other unexpected behavior.

aiotor.Pool is a true singleton. Every Pool() you create will refer to the same instance. If you need more proxies, just use the amount parameter (defaults to 10, which is more than sufficient, and actually too much).

proxies in the pool are refreshed at least once 15 minutes, getting new circuits from different countries, and new ip's.

Why another library around Onion/Tor?

for most people, setting up tor is already quite a task, implementing them as proxies in their programs requires much more work. the purpose of aiotor is to make it as easy as it can possibly get.

Show me how easy it is!

import logging
import asyncio
import aiotor

async def main():
    async with aiotor.ClientSession() as session:
        for _ in range(10):
            async with session.get('http://httpbin.org/ip') as response:
                print ( await response.json() )


logging.basicConfig(level=10)
asyncio.run(main())

this will output

Showing different ways to get a pool and showing how to use the pool as context manager

import aiotor

pool = aiotor.start()   # this gives you a running pool

pool2 = aiotor.Pool()   # this gives you the same pool (because singleton) if already bootstrapped

pool2.start()           # will start and bootstrap the pool, if not already running
                        # start() has the pool itself as return value

pool3 = aiotor.Pool.get_instance()  # same story

pool4 = aiotor.start()   # same story


import requests

# context manager

with pool:       
    # in this block, all network will be handled by the proxies and it will return 
    # different ip's on subsequent calls
    print(requests.get('http://httpbin.org/ip').text)

# not in context
# you will see your own ip
print(requests.get('http://httpbin.org/ip').text)
