python爬虫反爬取---设置IP代理自动变换requests.get()中proxy的IP

__author__ = 'Lee'
from headers import  requests_headers  # 上一篇文章中所写的自动转变headers文件
from bs4 import BeautifulSoup
import requests
header = requests_headers()  #调用requests_headers() 返回一个随机的headers文件
proxies = {'http': 'http://139.0.28.18:8080'}  #这个地方换一下ip和端口号
url = 'http://www.whatismyip.com.tw' #访问这个网站可以返回你的IP地址 以此验证是否变换成功
try:
    wb_data = requests.get(url,headers=header,proxies=proxies,timeout=5) #timeout 限定5秒相应后就退出执行
    soup = BeautifulSoup(wb_data.text,'lxml')
    print(soup)

    print('failed!')
