第六章 . requests 模块 - 【多接口请求】requests进行session 会话保持

#禅道登录

#1.MD5加密逻辑：md5(md5(password)+rand())
#2.password : quickon4You
import requests

s = requests.Session() #保持会话


#获取rand

• 核心机制​：Session 对象会自动存储服务器返回的 Cookie，并在后续请求中携带这些 Cookie，无需手动处理。例如，登录后访问需要认证的页面时，Session 会自动发送登录凭证

• ​应用场景​：适用于需要登录的网站（如禅道、电商平台），避免每次请求重复认证
