python 登录校园网

2021/11/25 python 校园网 脚本 共 2027 字，约 6 分钟

准备工具

  • 连接校园网 KMUST-WEB
  • Fiddle 抓包工具
  • python3
    • python使用到的第三方包requests
      pip install -i http://mirrors.aliyun.com/pypi/simple/ requests  --trusted-host mirrors.aliyun.com

总体流程

1、连接校园网, 比如KMUST-WEB, 跳出登录框, 此时会短暂跳出http://www.msftconnecttest.com/redirect, 可以在fiddle中看到这个url的请求和返回值.这个url中的response中包含wlanacname、ssid等登陆时需要用到的表单数据.

2、用账号密码登录 用账号密码登录后, fiddle中出现http:/<ip:port>/zportal/login/do的post请求, fiddle中的webForm中有提交的表单信息, raw中有请求头信息, 只需要将 username 和 password修改为自己的用户名密码, 即可模拟表单提交登录.

待处理问题

wlanacname、ssid 等字段可能会出现动态刷新的情况, 可以通过http://www.msftconnecttest.com/redirect中的返回值获取

还未实现登出logout功能

实现代码

    login(args.username,args.password)
