1.python爬虫浏览器伪装

#导入urllib.request模块import urllib.request#设置请求头headers=("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.221 Safari/537.36 SE 2.X MetaSr 1.0")#创建一个openeropener=urllib.request.build_opener()#将headers添加到opener中opener.addheaders=[headers]#将opener安装为全局urllib.request.install_opener(opener)#用urlopen打开网页data=urllib.request.urlopen(url).read().decode('utf-8','ignore')

2.设置代理

#定义代理ipproxy_addr="122.241.72.191:808"#设置代理proxy=urllib.request.ProxyHandle({'http':proxy_addr})#创建一个openeropener=urllib.request.build_opener(proxy,urllib.request.HTTPHandle)#将opener安装为全局urllib.request.install_opener(opener)#用urlopen打开网页data=urllib.request.urlopen(url).read().decode('utf-8','ignore')

3.同时设置用代理和模拟浏览器访问

#定义代理ipproxy_addr="122.241.72.191:808"#创建一个请求req=urllib.request.Request(url)#添加headersreq.add_header("User-Agent","Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)#设置代理proxy=urllib.request.ProxyHandle("http":proxy_addr)#创建一个openeropener=urllib.request.build_opener(proxy,urllib.request.HTTPHandle)#将opener安装为全局urllib.request.install_opener(opener)#用urlopen打开网页data=urllib.request.urlopen(req).read().decode('utf-8','ignore')

4.在请求头中添加多个信息

import urllib.requestpage_headers={"User-Agent":"Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/49.0.2623.221 Safari/537.36 SE 2.X MetaSr 1.0", "Host":"', #注意前面有. 'name':'xxxx', 'value':'xxxx', 'path':'xxxx' }#向phantomjs中添加cookiebs.add_cookie(cookie)

8.利用web_driver工具

#1.下载web_driver工具（如chromdriver.exe）及对应的浏览器#2.将chromdriver.exe放到某个目录，如c:\chromdriver.exefrom selenium import webdriverdriver=webdriver.Chrome(executable_path="C:\chromdriver.exe")#打开urldriver.get(url)

以上这篇Python实现爬虫设置代理IP和伪装成浏览器的方法分享就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
