一次差点放弃的抓包
2018-09-09 · via Hls on 轻风云

本人好友(骚木)给了一个网站发现视频资源不错,准备给扒下来

准备编辑器、fd、浏览器

1.启动fd,访问视频站,看一段视频,让它发送包,先放着不动

2.查看源码执行ctrl+f输入video查找,播放器src指向.m3u8文件

3.下载后用编辑器打开,咦,这是什么格式,查阅google资料,原来是hls视频

img

4.看一下抓的包,原来是把第3步最后一行作为参数,继续去浏览器下载,果然如此,把.ts文件全部下载本地就能整合成视频了

img

5.仔细看了一下发送的请求并返回的包,咦,这是什么,怎么有一行字符串,返回第4步看了一下差点漏了这一行:

EXT-X-KEY:METHOD=AES-128,URI=“key.key”

上帝请原谅我看不懂,大概意思是经过aes-128加密的,那一行字符串应该就是秘钥

抓包到此结束接下来用python获取文件并多线程下载,下载完成后用秘钥解密整合ts就成mp4啦
