首先找到我们需要蹂躏的网站
"http://www.wbdy.tv/play/29398_1_1.html"
在源代码中找到想要的播放内容
打开这个在源代码里面的网站
http://www.wbdy.tv/js/player/?url=https://video.buycar5.cn/20200810/3UbmZCEa/index.m3u8&id=29398&num=1&count=48&vt=1
查看发送的请求，看到有两个index,这个网站很有意思，从第一个连接给你一个m3u8，然后再从第一个m3u8里面给你第二个m3u8，这个后面说
我们先请求第一个index的url，获得m3u8响应文件，并下载下来，再读取第二个m3u8的文件，这样子全部的m3u8文件都获取到了，然后下载
获取到第一个m3u8的内容如下：/20200810/3UbmZCEa/2000kb/hls/index.m3u8
然后我们再看第二个m3u8的header：Request URL: https://video.buycar5.cn/20200810/3UbmZCEa/2000kb/hls/index.m3u8
怎么样 是不是很像，我们直接域名拼接过去，访问，看看resp是什么
resp是一长串ts文件内容，我们请求这个网站，并下载这些文件
写入文件之后，我们请求文件里面的ts连接地址，下载到本地为ts文件
下载完成之后，我们发现这些ts文件是打不开的，是加密过得，我们需要解密
我们可以看见第二个index 和 key.key 都指向key.key，ok 我们直接怼着key去
发送个请求，得到key的值是3c6ed8fbae9cdcbb
然后我们进行AES（#EXT-X-KEY:METHOD=AES-128,URI="https://ts1.yuyuangewh.com:9999/20200810/3UbmZCEa/2000kb/hls/key.key"）AES解密(链接里面有提示）
然后解密，解密之后再合并ts，即可。下面看代码
想运行代码的话自己在目录下先建好文件夹“video”
