python 使用链式代理

一般情况下加代理只加一个，让真正访问目标网站的IP是代理的IP，

代理链的用法可以使用第一个代理跳出墙，第一个代理连接第二个代理，绕过复杂的网络环境。

import socket
import pyChainedProxy as socks #import pyChainedProxy
import requests
# Enable debugging
def DEBUG(msg):
  print (msg)

socks.DEBUG = DEBUG


print("Check IP w/o proxyfying:  ",requests.get('http://ip-api.com/json').content)

# Configure a default chain
chain = [
  'socks5://localhost:7890/', 
  'http://testmidu-zone-adam:testmidu@43.153.102.235:6004'

]
socks.setdefaultproxy()

for hop in chain:
   socks.adddefaultproxy(*socks.parseproxy(hop))

# Configure alternate routes (No proxy for localhost)
socks.setproxy('localhost', socks.PROXY_TYPE_NONE)
socks.setproxy('127.0.0.1', socks.PROXY_TYPE_NONE)


# Monkey Patching whole socket class (everything will be proxified)
rawsocket = socket.socket
socket.socket = socks.socksocket
# Everything will be proxied!

print("Check IP After proxyfying:  ",requests.get('http://ip-api.com/json').content)
