Python程序中如何使用亿牛云爬虫代理

1.先在亿牛云客服处获取爬虫代理信息

2.添加代理信息

 #! -*- 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)s@%(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

3 注意：亿牛云的爬虫代理每秒请求次数是有限制，可以在程序中对请求速度进行设置
