租了一台服务器，今天终于派上了用场---刷智慧树的网课。
其实，这话有点夸大了，是刷视频。
一、环境：python3.* selenium chrome chromedriver windows10
二、程序功能：
输入课程号，（手动）登录智慧树， 然后程序播放课程下的视频，将进步发送给自己微信助手。
三、程序：
（1）智慧树刷课

四、存在的问题：
（1）无法自动登录：利用js 或者 send_key() 会出现滚动条， 而这个滚动条即使是手动也没有办法验证成功。
我怀疑它是绑定了keydown监听事件， 如果不出现keydown事件，那么就基本不拒绝了。因为上面两种方法都不会触发keydown事件。
（2）太多太多太多的try、except
