前言
今天在观看视频的过程中，fiddler抓包看了一下请求，发现请求中无cookie相关的参数，心中窃喜，我是不是可以通过请求来访问这个视频呢？
于是复制请求地址，在浏览器打开，what？
1.不能使用浏览器直接打开（可以使用windows自带的播放软件打开）；2.打开没有头像；3.而且只有几s就结束了；4.可以另存为.ts格式的文件；5.视频文件格式：video/mp2t；
参考： ，百度如何播放，提到了HLS协议、VLC播放器；
HLS是Apple的动态码率自适应技术。包括一个m3u的索引文件，TS媒体分片文件和key加密串文件；
那就看一看响应结果，EXTM3U格式的文件
百度结果：m3u文件格式，本质上说不是音频文件，它是音频文件的列表文件，是纯文本文件；你下载下来打开它，播放软件并不是播放它，而是根据它的记录找到网络地址进行在线播放。
百度到VLC功能强大
VLC如何播放m3u格式的文件呢？ 就是如下图，VLC——>媒体中打开m3u格式的文件 （可随意命名文件）
可是我明明添加了文件，却不播放，fiddler对比查看请求发现，没有请求协议，域名之类的，尝试手动添加一个，发现可以播放了，大喜~
那如何播放多个文件呢，肯定是通过请求，好吧一个一个找；终于找到了所有章节的hls；然后通过拼接。。。可以播放了
