本篇文章仅供学习讨论。
文章中涉及到的代码、实例，仅是个人日常学习研究的部分成果。

我博客里面也不止发布了一篇关于阿里系签名的文章了，但成体系、能应用的功能一直没有开发出来。
虽然一大部分原因是因为本人懒，有空的时候就研究下，没空了就直接搁置。
本质上还是去学习人家的算法和架构，最终学习到的东西可以应用到自己开发的产品上。
最近把闲鱼/淘宝/大麦的应用都放到一起研究了下，终于，在算法研究的长征路上，又向前走了一小步——在unidbg的基础上实现了相关算法。但知道的越多，发现未知的越多。在设备层面、基础参数层面，发现阿里不愧是大厂，领先这些小程序员们一整个大气层。
接下来又是传统节目——炫技环节：
