因工作需要，需要对音的一些视频用户数据进行采集分析，发现近期的一些版本里面加了好几个算法，有as,cp(早期就这两个），mas,X-Gorgon，X-SS-STUB算法，很多关键key之间有相互关联，只要有一个环节算错了，就会请求不到数据。目前版本的音加了很多的验证，及代码混淆，难度偏大，一般逆向比较困难。逆向的时候要有足够的耐心，当然也有其他投机的方法就是了，看思路。

关于核心算法是不能公开（这类代码，都会被要求删除），我这里就分享下早期版本逆向as,cp算法之后的代码，可以采集视频，推荐视频，用户粉丝数、点赞、关注，作品信息等，这方面的采集不需要做任何的登录，算法生成也是不需要经过抖音服务器，无限生成。

代码如下，刚学python不久，代码写的烂就别喷我了

现在这个项目我自己已经没有在维护了，不知道抖音的api有没有更新新算法，需要的同学评论区留下邮箱，但不保证算法正常使用
