之前在考RHCE，视频很好看，但是有观看有效期，一直想下某机构的精品班视频，网上看到了ali m3u8的加密下载器，就想着自己操作下载下来，以后被窝里偷摸看。以下是下载器开源地址：

在这里分享某机构精品班视频的下载思路。
主要还是用webdriver，其他啥也没用，丝毫没有技术含量，但是能用。网站结构改变，你代码就要变

简单明了就一步就是拿playauth和void
我也不写我的心路历程了，就简单明了给你们抛出来。
我是各种抓包结果发现某1就直接给获取上头这两东西的地址就写在网页的script里头。直接进课程地址”center/course/lesson/index?id=7065_577896“

直接在console里输入document.querySelector('body > script:nth-child(13)')
```
<script>let timer = null;
let finish = false;
let count = 0;
let hasSign = 0;
//阿里云播放器
var aliplayparam = {
CENTER_URL : '*****/center/',
person_num: '***',
username: '"***"',
type: 'wejoboutcourse',
lesson_id: '7065_577896',
id: 'df338cfc9c4347459ad88e8195683be',
sign: 'c0e5CFAOXgVVAAQCAQACAFFdAFMAAVcAwUAUAZVCQJfBQAFAFANBgEADABcDF1dDQNVDQEHDldTAxgHBl4FWQ1XAQUEBgw',
userid:'******',
timestr: new Date().getTime(),
random: Math.random(),
playerid: 2,
reportSwitch: true,
autoplay: true,
playcallback: function () {
         if(timer) {
      clearInterval(timer);
   }
   if(count == 0 || !finish) {
      timer = setInterval(() => {
      $.ajax({
               url: '/center/user/sign/auto-sign',
               type: 'GET',
               success: function (res) {
                  res = JSON.parse(res);
                  count++;
                  if(res.status == '0') {
                     finish = true;
                     clearInterval(timer);
                     if(res.msg != '') {
                           $("#ctoplayerbox1").append(`<div class='record-study'>${res.msg}</div>`);
                     }
                     setTimeout(() => {
                           $('.record-study').remove();
                     }, 3000);
                  }
               }
         })
      }, 31000)
   }
      },
}
```

我们就要里头的lesson_id、id和sign,抓住来再给他合并一下就好了
/center/player/play/vod-play-auth?type=wejoboutcourse&lesson_id=$lesson_id&id=$id&sign=$sign&lesson_type=course&is_try=0

然后再访问一下合并完的地址就回返回一个json
```

```
我们要的authplay 和void就在里头，直接用上头分享的工具直接下载就完事了，其他就写个脚本，直接给整个课表爬下来然后慢慢下就完事了。成品分享就再说了，写的是稀烂，就提供思路就差不多了。有authplay和void上头工具会直接合并成MP3有声音有画面，终于可以晚上被窝偷摸看了

你试试浏览器下载个flash video downloader插件

没有屌用，还有一个直接下缓存的插件叫CoCoCut，这种做不到批量，一个个下很麻烦。写个爬虫视频地址全抓下来，在一起批量下载多舒服
