// 四川机电职业技术学院(zhjw.scemi.com) 拾光课程表适配脚本
// 基于正方新一代教务系统接口适配
// 维护者：小漫君(xiaomanjun233)
// 出现问题请提issues或者提交pr更改,这更加快速
//
// 通过正方接口 xskbcx_cxXsgrkb 拉取个人课表 JSON（kbList），解析课程名、教师、教室、
// 星期、节次和周次（含单双周）。集中实践课（军训、毕业设计等）无星期节次，直接忽略不导入。
// 交互上自动读取教务系统的学年/学期下拉列表，用户只需依次点选即可，无需手动输入。
// 通过 xskbcx_cxXskbcxIndex 读取学年学期选项、xskbcxZccx_cxZcByXnxq 取所选学期开学日期，
// 并优先从 xskbcx_cxRjc 动态读取该校真实节次作息时间，读取失败时跳过作息导入。
//
// 使用方式：校内网络下从校内门户(192.168.73.155/personal-center)登录后进入教务，
// 在教务系统任意页面（如首页、移动端课表页）直接执行导入即可，无需进入课表查询页面。
// 脚本通过接口自动读取学年学期并获取课表与节次作息。
//
// 注意：该校教务仅在校园网内开放：校内门户为 192.168.73.155，教务服务为 192.168.73.166（/jwglxt），
// 公网域名 zhjw.scemi.com 的请求会被 webproxy.scemi.com 按来源网段拦截（403）。
// 脚本会先在当前页面所在主机上尝试正方接口，未命中时回退到校内教务主机，因此从门户或课表页执行都可以。
