// 郑州汽车工程职业学院 (zzvcae.edu.cn) 拾光课程表适配脚本
// 平台：树维 EAMS 教务（与郑州航空工业管理学院 jwglxt.zua.edu.cn 同平台）
// 参考：郑州航院 zua.js（树维 EAMS Fetch 解析流程），针对本校 CAS 单点登录与作息做适配
//
// 使用说明：
//   1. 在 App 内本适配的入口地址会打开 CAS 统一身份认证登录页
//   2. 登录 CAS 成功后，进入【服务大厅】→【学生课表查询】，等待课表页面加载完成
//   3. 回到 App 点击【执行导入】即可
//   注意：教务系统禁止从 jw.zzvcae.edu.cn 直接登录，必须经由 CAS 登录并在服务大厅访问过一次课表，
//         这样 jw.zzvcae.edu.cn 域下才会建立有效的教务会话，脚本的接口请求才能成功。
