动手写自动挂机刷课脚本

失踪人口又回来了，🤣🤣

受疫情影响，所有的课程都是以网课形式存在，后又要自己选一个通识网课，这无疑让本就悲惨的认识雪上加霜，于是，我研究了一下智慧树的部分api接口，编写了一个较简单的挂机脚本。此篇文章以做记录。

附上shi'p视频播放界面的api请求列表

api request

其中

getLoginUserInfo 为get请求，
- 附带参数 dateFormate：时间戳，
返回的数据中包含登录者的姓名和一个 uuid , 这个uuid 比较重要后面的几个请求都需要以它作为参数传递
videolist 为post请求，
携带参数 recruitAndCourseId: 这个可以从地址栏中获取，目测是对课程号处理过后得到的值，uuid:上面提到过的uuid ，dateFormate:时间戳，
返回数据为播放列表的信息包含视频id 课程id 课程名称等等，本次用到的是其中的name lessonId id内容。处理过滤后存储在一个map中
loadVideoPointerInfo 为post请求
携带参数 lessonId: 当前播放内容的小节课程id 非总的课程id ，lessonVideoId: 播放的视频id （* 此字段非必带，仅播放的小节课程处于小课程时才需要用以区分例如当2.3作为单独一小节时不需要此字段，若2.3 有子课程时，2.3.1 2.3.2....均需要该字段）uuid: 第一个api中的，dateFormate*: 时间戳
返回数据返回此视频所有的答题时间点，即多少分多少秒会出现答题
lessonPopupExam 为post请求
- 携带参数 lessonId: 同上 lessonVideoId: 同上 time: 答题的时间点可由上一个api返回数据中获取 uuid: 同上 dateFormate:同上
- 返回数据该数据返回问题及答案选项列表中有个result字段该字段为1则说明该选项时答案之一。

基于以上四个api在对页面的标签进行选择，通过jquery对页面进行操作模拟出用户的点击操作，api请求我没有过多的进行分析和使用，因为这个数据是直接发送回服务端，请求太多容易出纰漏，被发现出端倪，所以脚本中的网络请求则能省就省。
于是有了如下的第一个版本
代码质量有点低，各位就当看个乐吧，望各位轻点喷。

关于如何使用的问题那可就简单了把你写好的代码编译成js 然后复制到网页开发者工具的控制台中，回车运行即可~~~
