抓包分析发现请求头有参数u-sign是加密的载荷没有进行加密直接跟栈分析。 进入第二个栈打上断点分析有没有加密位置。 可以看到参数已经进行加密了 往上跟栈找到异步位置打上断点发现参数没了这说明加密在异步的函数中 直接进入t的第一个函数一下子就找到了加密位置打上断点发现就是这里加密加密函数是o 进入o函数里面去看看打上断点发现最后的n就是加密位置。 复制下来写好函数n没有定义直接去找n 不要直接进入n函数去复制会有很多模块累死人也搞不定。也不要猜测是MD5我试过了不对的。 往上看看有新发现。原来是一个webpack。 打上断点进入加载器r先全部复制下来。 导出加载器补环境现在就去找函数模块了。 缺少什么模块就去找什么函数模块添加模块 最终结果 现在我们有了u-sign,可以带着请求头去访问数据了。
