- // resources/SUEP/SUEP_03.js
- // 上海电力大学 本科教务系统(eams / 上海树维)拾光课程表适配脚本 —— 接口探测版
- //
- // 本脚本改自本仓库中天津农学院 (TJAU) 的适配脚本(作者:星河欲转)。
- // 两者是同一套「树维 eams」系统,因此沿用它的整体思路:
- // - 用接口探测 ids / tagId,不依赖用户先打开「我的课表」页面;
- // - 用「按周建矩阵、再切连续节次块」的算法合并课程,能正确处理
- // 「同一门课不同周次占用不同节次」这种不规则情况。
- // 只把 URL、解析规则和节次时间换成了上海电力大学的实际情况。
- //
- // 导入页(adapters.yaml 的 import_url):https://jw.shiep.edu.cn/eams/index.action
- //
- // 前置条件:**只需登录**,不需要打开课表页。
- //
- // 与 SUEP_01.js / SUEP_02.js 的差别:
- // SUEP_01 读当前页面内联脚本;SUEP_02 已登录后调接口、但参数取自当前页面;
- // 本脚本连参数都由接口探测,因此对页面状态没有要求。
- const EAMS_BASE = "https://jw.shiep.edu.cn/eams";
- /**
- * 同一接口在短时间内被连续请求时,服务端会返回一个约 4 KB 的「精简版」页面
- * (不含工具栏,也不含 ids / tagId 等标记),间隔约 1 秒再请求就恢复正常。
- * 实测:14 次连发只有第 1 次完整;间隔 2 秒的 4 次请求则全部完整。
- * 这不是登录失效,所以收到这种响应应当退避重试,而不是直接报错。
