Core proxy (SOCKS4, SOCKS5, HTTP tunneling) functionality for Python

Project description

python-socks

The python-socks package provides a core proxy client functionality for Python. Supports SOCKS4(a), SOCKS5, HTTP (tunneling) proxy and provides sync and async (asyncio, trio) APIs.

Requirements

  • Python >= 3.6
  • async-timeout >= 3.0.1 (optional)
  • trio >= 0.16.0 (optional)

Installation

only sync proxy support:

pip install python-socks

to include optional asyncio support:

pip install python-socks[asyncio]

to include optional trio support:

pip install python-socks[trio]

Usage

We are making secure HTTP GET request via SOCKS5 proxy

Sync

import ssl
from python_socks.sync import Proxy

proxy = Proxy.from_url('socks5://user:password@127.0.0.1:1080')

# `connect` returns standard Python socket in blocking mode
sock = proxy.connect(dest_host='check-host.net', dest_port=443)

sock = ssl.create_default_context().wrap_socket(
    sock=sock,
    server_hostname='check-host.net'
)

request = (
    b'GET /ip HTTP/1.1\r\n'
    b'Host: check-host.net\r\n'
    b'Connection: close\r\n\r\n'
)
sock.sendall(request)
response = sock.recv(4096)
print(response)

Async (asyncio)

import ssl
import asyncio
from python_socks.sync import Proxy

proxy = Proxy.from_url('socks5://user:password@127.0.0.1:1080')

# `connect` returns standard Python socket in non-blocking mode 
# so we can pass it to asyncio.open_connection(...)
sock = await proxy.connect(dest_host='check-host.net', dest_port=443)

request = (
    b'GET /ip HTTP/1.1\r\n'
    b'Host: check-host.net\r\n'
    b'Connection: close\r\n\r\n'
)

reader, writer = await asyncio.open_connection(
    host=None,
    port=None,
    sock=sock,
    ssl=ssl.create_default_context(),
    server_hostname='check-host.net',
)

writer.write(request)
response = await reader.read(-1)
print(response)

Async (trio)

import ssl
import trio
from python_socks.async_.trio import Proxy

proxy = Proxy.from_url('socks5://user:password@127.0.0.1:1080')

# `connect` returns trio socket 
# so we can pass it to trio.SocketStream
sock = await proxy.connect(dest_host='check-host.net', dest_port=443)

request = (
    b'GET /ip HTTP/1.1\r\n'
    b'Host: check-host.net\r\n'
    b'Connection: close\r\n\r\n'
)

stream = trio.SocketStream(sock)

stream = trio.SSLStream(
    stream, ssl.create_default_context(),
    server_hostname='check-host.net'
)
await stream.do_handshake()

await stream.send_all(request)
response = await stream.receive_some(4096)
print(response)
