有关识别课程目录以及课程视频问题 #13
Description
今天测试中发现获取课程目录的时候，课程没有加载出来Chrome就直接闪退，不知道是自己网络问题还是网站更新后的问题,后来修改get课程代码得以解决 修改如下
await page.goto(url, {
waitUntil: 'networkidle0' // 网络空闲说明加载完毕
});
然后在获取课程学习内容进度的时候，在进行到某一科目的时候会报以下错误
Unhandled Rejection at: Promise Promise {
Error: Error: failed to find element matching selector ".activity-title > a.title"
at ElementHandle.$eval (D:\Ouchn\auto-study-master\node_modules\puppeteer-core\lib\cjs\puppeteer\common\JSHandle.js:880:19)

请问需要如何解决？ 万分感谢！
