Python3之利用Cookie模擬登陸

Python3之利用Cookie模擬登陸

利用Cookie模擬登陸步驟：

1.       在瀏覽器輸入http://demo.bxcker.com，輸入用戶名和密碼登陸。

2.登陸成功點「客戶管理」模塊。

 

3. 進入客戶管理模塊，顯示客戶列表。

 

4.經過抓包工具抓取客戶列表，獲得登陸後的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工具處理抓到的http請求頭信息替換成字典

 

選擇內容替換的方式是用正則表達式

內容填寫：^(.*):\s(.*)$  （須要把header文件內容處理成字典，中間有個空格，因此加個\s）

替換爲填寫："\1":"\2",

點全換，處理完成以後變成以下：

"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. 處理完成以後直接拷貝到Python定義的頭信息變量headers={}裏

 

7. 整理headers 信息（去掉一些沒用的，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. 編寫完整的程序。

 

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 做爲Request()方法的參數，構造並返回一個Request對象

request = urllib.request.Request(url)

# Request對象做爲urlopen()方法的參數，發送給服務器並接收響應

response = urllib.request.urlopen(request)

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

print(html)

 

運行結果：

能夠看到客戶列表裏的相關信息，證實是經過Cookie登陸成功，而後跳轉到客戶管理模塊，獲取的客戶信息。
