Features

• SOCKS4, SOCKS4a and SOCKS5 version
• SocksConnector for aiohttp
• SOCKS "CONNECT" command

TODO

• UDP associate
• TCP port binding

Usage

direct usage

import asyncio
import aiosocks


async def connect():
  socks5_addr = aiosocks.Socks5Addr('127.0.0.1', 1080)
  socks4_addr = aiosocks.Socks4Addr('127.0.0.1', 1080)

  socks5_auth = aiosocks.Socks5Auth('login', 'pwd')
  socks4_auth = aiosocks.Socks4Auth('ident')

  dst = ('github.com', 80)

  # socks5 connect
  transport, protocol = await aiosocks.create_connection(
      lambda: Protocol, proxy=socks5_addr, proxy_auth=socks5_auth, dst=dst)

  # socks4 connect
  transport, protocol = await aiosocks.create_connection(
      lambda: Protocol, proxy=socks4_addr, proxy_auth=socks4_auth, dst=dst)

  # socks4 without auth and local domain name resolving
  transport, protocol = await aiosocks.create_connection(
      lambda: Protocol, proxy=socks4_addr, proxy_auth=None, dst=dst, remote_resolve=False)

  # use socks protocol
  transport, protocol = await aiosocks.create_connection(
      None, proxy=socks4_addr, proxy_auth=None, dst=dst)


if __name__ == '__main__':
  loop = asyncio.get_event_loop()
  loop.run_until_complete(connect())
  loop.close()

error handling

try:
  transport, protocol = await aiosocks.create_connection(
      lambda: Protocol, proxy=socks5_addr, proxy_auth=socks5_auth, dst=dst)
except aiosocks.SocksConnectionError:
  # connection error
except aiosocks.LoginAuthenticationFailed:
  # auth failed
except aiosocks.NoAcceptableAuthMethods:
  # All offered SOCKS5 authentication methods were rejected
except (aiosocks.InvalidServerVersion, aiosocks.InvalidServerReply):
  # something wrong
except aiosocks.SocksError:
  # something other

aiohttp usage

import asyncio
import aiohttp
import aiosocks
from aiosocks.connector import SocksConnector


async def load_github_main():
  addr = aiosocks.Socks5Addr('127.0.0.1', 1080)
  auth = aiosocks.Socks5Auth('proxyuser1', password='pwd')

  # remote resolve
  # conn = SocksConnector(proxy=addr, proxy_auth=auth, remote_resolve=True)

  # or locale resolve
  conn = SocksConnector(proxy=addr, proxy_auth=auth, remote_resolve=False)

  try:
    with aiohttp.ClientSession(connector=conn) as ses:
      async with session.get('http://github.com/') as resp:
        if resp.status == 200:
          print(await resp.text())
  except aiohttp.ProxyConnectionError:
    # connection problem
  except aiosocks.SocksError:
    # communication problem


if __name__ == '__main__':
  loop = asyncio.get_event_loop()
  loop.run_until_complete(load_github_main())
  loop.close()
