0x01 頭部數據偽裝思路

通過http向服務器提交數據,以下是通過Fiddler 抓取python沒有偽裝的報文頭信息

GET /u012870721 HTTP/1.1Accept-Encoding: identityHost: blog.csdn.netUser-Agent: <span style="color:#ff0000;">Python-urllib/3.6</span>Connection: close

Python-urllib/3.6

很明顯啊，我們暴露了。現在要問了，該怎么！模擬瀏覽器，讓自己偽裝成瀏覽器，一下是瀏覽器訪問發送的頭部數據

Connection: keep-aliveUpgrade-Insecure-Requests: 1User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36Referer: http://write.blog.csdn.net/postlistAccept-Encoding: gzip, deflateAccept-Language: zh-CN,zh;q=0.8

0x02代碼實現

from urllib import requesthtml_url = "http://blog.csdn.net/u012870721";#偽裝構造頭header ={ "Connection": "keep-alive", "Upgrade-Insecure-Requests": "1", "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36", "Accept":" text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8", "Accept-Encoding": "gzip,deflate", "Accept-Language": "zh-CN,zh;q=0.8"};#int main()#{req = request.Request(url=html_url, headers=header);resp = request.urlopen(req);# return 0;# }

偽裝后進行發送的信息頭

GET /u012870721 HTTP/1.1 Host: blog.csdn.net Connection: close Upgrade-Insecure-Requests: 1 User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8 Accept-Encoding: gzip,deflate Accept-Language: zh-CN,zh;q=0.8 

以上這篇python通過偽裝頭部數據抵抗反爬蟲的實例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林站長站。
