# -*- coding: UTF-8 -*-
from urllib import request

  #访问网址
  url = 'http://www.whatismyip.com.tw/'
  #这是代理IP
  ip = '27.155.101.233:3128'
  #设置代理ip访问方式，http和https
  proxy = {'http':ip,'https':ip}
  #创建ProxyHandler
  proxy_support = request.ProxyHandler(proxy)
  #创建Opener
  opener = request.build_opener(proxy_support)
  #添加User Angent

  #安装OPener
  request.install_opener(opener)
  #使用自己安装好的Opener
  response = request.urlopen(url)
  #读取相应信息并解码
  html = response.read().decode("utf-8")
  #打印信息
