Python的requests包中使用session管理cookie

 使用session管理cookie，本质是从requests.session()获取session，然后使用session发送验证码数据，然后cookie等数据就被存储到session中了。在次使用该cookie发送请求的时候就会自带cookie，前一次请求的cookie结果被存储。

1. # 读入request 包
   import requests

   1. 

2. # 编写参数
   # 登录请求URL
   login_req_url = "http://127.0.0.1/index.php?m=Home&c=User&a=do_login&t=0.26704270445050515";# 登录参数
   login_data_info = {"username": "13800138006","password": "123456","verify_code": "8888",
   }

   1. 

3. # 获取登录验证码请求get_verigy_code_url = "http://127.0.0.1/index.php?m=Home&c=User&a=verify&r=0.4507740559733051"

   1. 

4. # 发送获取验证码请求,获取session
   session_send_data = requests.session()result_response_data = session_send_data.get(url=get_verigy_code_url);
   print(result_response_data.content)

   1. 

5. # 获取session,使用session发送登录请求
   login_sussces = session_send_data.post(url=login_req_url, data=login_data_info,headers={"Content-Type": "application/x-www-form-urlencoded"});
   print("使用session登录:  ", login_sussces.content)

   1. 

6. # 使用cookie 登录
   result_response_data = requests.get(url=get_verigy_code_url);cookie_test = result_response_data.cookies
   print(cookie_test)
   cookie_login = requests.post(url=login_req_url, data=login_data_info,headers={"Content-Type": "application/x-www-form-urlencoded"},cookies=cookie_test)
   print("使用cookie登录: ", cookie_login.content)
