安阳工学院宽带更新自动更新脚本[可能已失效]

教程

七月五号的时候ayit更新了dr.com的认证方式，更换了Portal认证的方式，原来的脚本没有办法使用了。又抓了下包分析了一波，还好是网页认证比较好搞。以前的时候是直接发post包就可以了，现在需要1.1.1.1重定向给你分配wlanuserip地址然后向这个指定地址进行发送数据,发送的参数也进行了改变。新版的需要携带cookie信息进行校验

其实跟原来的差不多只不过多了一次重定向

python脚本

[task] 填写xuehao，passwd，IP [/task]

Liunx环境shell脚本

如果你想要在linux环境下进行使用可以使用以下脚本

自动化脚本自动执行

思路： 如果已经登陆则http://172.168.254.4的响应title为注销页 其余情况则为 上网登录页 可以定时进行判断进行申请

[task]我是用了NID进行判断 服务器编码为GBK格式转换复杂 [/task]
