Python3之利用Cookie模拟登录

Python3之利用Cookie模拟登录

利用Cookie模拟登录步骤：

1.       在浏览器输入http://demo.bxcker.com，输入用户名和密码登录。

2.登录成功点“客户管理”模块。

3. 进入客户管理模块，显示客户列表。

4.通过抓包工具抓取客户列表，得到登录后的Cookie信息。

GET http://demo.bxcker.com/customer/index.shtml HTTP/1.1

Host: demo.bxcker.com

Connection: keep-alive

Pragma: no-cache

Cache-Control: no-cache

Accept: */*

X-Requested-With: XMLHttpRequest

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36

Referer: http://demo.bxcker.com/

Accept-Encoding: gzip, deflate

Accept-Language: zh-CN,zh;q=0.9

Cookie: IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ

5.利用sublime text工具处理抓到的http请求头信息替换成字典

选择内容替换的方式是用正则表达式

内容填写：^(.*):\s(.*)$  （需要把header文件内容处理成字典，中间有个空格，所以加个\s）

替换为填写："\1":"\2",

点全换，处理完成之后变成如下：

"Host":"demo.bxcker.com",

"Connection":"keep-alive",

"Pragma":"no-cache",

"Cache-Control":"no-cache",

"Accept":"*/*",

"X-Requested-With":"XMLHttpRequest",

"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36",

"Referer":"http://demo.bxcker.com/",

"Accept-Encoding":"gzip, deflate",

"Accept-Language":"zh-CN,zh;q=0.9",

"Cookie":"IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ",

6. 处理完成之后直接拷贝到Python定义的头信息变量headers={}里

7. 整理headers 信息（去掉一些没用的，保留一些重要的）

"Connection":"keep-alive",

"X-Requested-With":"XMLHttpRequest",

"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36",

"Referer":"http://demo.bxcker.com/",

"Cookie":"IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ",

8. 编写完整的程序。

 

from urllib import parse

import urllib.request

url ="http://demo.bxcker.com/customer/index.shtml"

headers={

"Host":"demo.bxcker.com",

"Connection":"keep-alive",

"Pragma":"no-cache",

"Cache-Control":"no-cache",

"Accept":"*/*",

"X-Requested-With":"XMLHttpRequest",

"User-Agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36",

"Referer":"http://demo.bxcker.com/",

"Accept-Encoding":"gzip, deflate",

"Accept-Language":"zh-CN,zh;q=0.9",

"Cookie":"IEX-JSESSIONID=WFPlPUVbbbkQ76XPCr9tXRB4voK0eESo; Hm_lvt_4320d635415dcfd7831a11fa64aec173=1526347940; Hm_lpvt_4320d635415dcfd7831a11fa64aec173=1526347940; SPRING_SECURITY_REMEMBER_ME_COOKIE=UE9kSDFGMnVsS291S2Z2V1k5c1daQT09OjZxWFVDUUhoVmR2UTdsWnRFRnlZZ0E9PQ",

}

# url 作为Request()方法的参数，构造并返回一个Request对象

request = urllib.request.Request(url)

# Request对象作为urlopen()方法的参数，发送给服务器并接收响应

response = urllib.request.urlopen(request)

html = response.read().decode('utf-8')

print(html)

运行结果：

可以看到客户列表里的相关信息，证明是通过Cookie登录成功，然后跳转到客户管理模块，获取的客户信息。
