Python中的requests框架使用爬虫代理的方案

#! -- encoding:utf-8 --

    import requests
    import random

    # 要访问的目标页面
    targetUrl = "http://httpbin.org/ip"

    # 要访问的目标HTTPS页面
    # targetUrl = "https://httpbin.org/ip"

    # 代理服务器
    proxyHost = "t.16yun.cn"
    proxyPort = "31111"

    # 代理隧道验证信息
    proxyUser = "username"
    proxyPass = "password"

    proxyMeta = "http://%(user)s:%(pass)[email protected]%(host)s:%(port)s" % {
        "host" : proxyHost,
        "port" : proxyPort,
        "user" : proxyUser,
        "pass" : proxyPass,
    }

    # 设置 http和https访问都是用HTTP代理
    proxies = {
        "http"  : proxyMeta,
        "https" : proxyMeta,
    }


    #  设置IP切换头
    tunnel = random.randint(1,10000)
    headers = {"Proxy-Tunnel": str(tunnel)}



    resp = requests.get(targetUrl, proxies=proxies, headers=headers)

    print resp.status_code
    print resp.text
