0x00 环境
系统环境:win10
编写工具:JetBrains PyCharm Community Edition 2017.1.2 x64
python 版本:python-3.6.2
抓包工具:Fiddler 4
0x01 头部数据伪装思路
通过http向服务器提交数据,以下是通过Fiddler 抓取python没有伪装的报文头信息
GET /u012870721 HTTP/1.1 Accept-Encoding: identity Host: blog.csdn.net User-Agent: <span style="color:#ff0000;">Python-urllib/3.6</span> Connection: close
Python-urllib/3.6
很明显啊，我们暴露了。现在要问了，该怎么！模拟浏览器，让自己伪装成浏览器，一下是浏览器访问发送的头部数据
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 Referer: http://write.blog.csdn.net/postlist Accept-Encoding: gzip, deflate Accept-Language: zh-CN,zh;q=0.8
0x02代码实现
from urllib import request
html_url = "http://blog.csdn.net/u012870721";
#伪装构造头
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;
# }
伪装后进行发送的信息头
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
