Python--055论一只爬虫的自我修养3：隐藏

游戏小虾米

Tip：


一，理论



二，应用
1

import urllib.request
import random

url = 'http://www.whatismyip.com.tw'

ipList = ['116.19.96.131:9797','111.155.116.233:8123','111.155.116.200:8123']

proxy_support = urllib.request.ProxyHandler({'HTTP':random.choice(ipList)})

opener = urllib.request.build_opener(proxy_support)
opener.addheaders = [('User-Agent', 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36')]

urllib.request.install_opener(opener)

response = urllib.request.urlopen(url)
html = response.read().decode('utf-8')

print(html)

结果无法访问，可能原因是www.whatismyip.com.tw无法访问，直接网页访问也打不开，只能在百度快照里看一下
三，课后练习
