URL: ${window.location.href} 触发了捕获规则

确保当前浏览器地址栏URL与其一致，如不一致，可能是iframe嵌入导致，请前往该页面进行处理！

请通过点击页面左上角齿轮图片（看不见请刷新），将“已显示字段”按次序设置为：
课程名称、学分、是否在用、课程编号、教学大纲是否录入、开课单位
设置完成后滚动小齿轮的窗口到底部，点击确定。
顺序必须一致！！
采集完成后，点击导出CSV 以导出格式化数据，点击”打开转换页面“以转换为json。
注意：刷新页面会丢失已采集的数据

已采集课程数量：0

序号	课程名称	学分	是否在用	课程编号	教学大纲录入	开课单位	操作（课程大纲查看）
