1.某道翻译js逆向sign值
首先找到这个请求接口
这个接口就是我们请求翻译的接口 发现有个sign值，这就是我们需要逆向的值
再看看这个接口的响应
可以发现这个响应是被加密的，我们还需要去逆向解密这个被加密的响应,这篇就单纯讲一下逆向这个sign值把
查看调用堆栈
下断点，一步步跟栈发现了sign的生成位置
进入这个k函数看看sign是由S函数生成的
S调用了_函数
发现 _ 这个函数内部调用了r 又发现r其实是个webpack打包打导出函数
我们进去r.createHash 函数看看
发现 如果传入的参数是md5 他会返回 一个new i 对象 那就简单了 我们看看i这个构造函数在哪就OK了
继续跟进看看i这个构造函数
发现这个构造函数就是88276这个打包模块里面的s函数
接下来就模仿webpack把函数copy下来就行了
我逆向sign完整代码如下
