python通過偽裝頭部資料抵抗反爬蟲

這篇文章主要介紹了關於python通過偽裝頭部資料抵抗反爬蟲，有著一定的參考價值，現在分享給大家，有需要的朋友可以參考一下

0x00 環境

系統內容:win10

編寫工具:JetBrains PyCharm Community Edition 2017.1.2 x64

python 版本:python-3.6.2

抓包工具:Fiddler 4

0x01 頭部資料偽裝思路

通過http向伺服器提交資料,以下是通過Fiddler 抓取python沒有偽裝的報文頭資訊

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，該怎麼！類比瀏覽器，讓自己偽裝成瀏覽器，一下是瀏覽器訪問發送的頭部資料

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;# }

偽裝後進行發送的資訊頭

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
