网上书店电子商务网站建设上海网站推广策划
一、打开网站，使用账号密码登录
账号：aiyou@123.com
密码：123456
二、通过F12抓包，抓到如下数据，发现密码加密了
三、加密结果是32位，首先考虑是md5加密。
四、全局搜索pwd，点击右上角，点击搜索
五、挨个文件查看，然后局部搜索“pwd:”，快捷键ctrl+f
六、找到给pwd赋值的语句，双击左边，下断，
七、重新点击登录按钮，会自动断下来
八、选中“m(n.pwd.substr(0, 16))”，鼠标放上去，自动提示加密结果，可以分析除，是m函数进行了加密
九、把鼠标放到m函数上，自动弹出下面的对话框，可以查看m函数所在的位置，点击进入该函数
十、这是一个匿名函数
十一、将该函数的同作用域范围的函数都复制到调试软件，并将该匿名函数改为aiyou函数，点击加载代码，成功加载
十二、调用该函数，双击该函数，输入参数，点击运行获取结果
十三、Python代码实现
1、将该JS代码复制jiami.js文件
function getpwd(pwd) {return pwd;
