+# 知识点： webpack打包
+
+凡是遇到webpack打包的js项目，直接全局导出解密模块去执行，通过在浏览器环境测试成功后在改写成node环境下的执行。
+
+## 登陆页面
+
+**参数：password2**
+
+请求登陆页面
+
+![请求](./img/1.png)
+
+发现`password2`参数加密
+
+![请求](./img/2.png)
+
+全局搜索`password2`，找到加密点，不难发现`password2`是通过函数`e = this.rsaPassword(this.passwordNode.value())`得到
+
+![请求](./img/3.png)
+
+进入函数调试，发现类似RSA加密
+
+![请求](./img/4.png)
+
+这公钥没有做base64，不能确定是否存在魔改的情况
+
+![请求](./img/5.png)
+
+先不管他，直接导出模块执行。把index.js全部复制到浏览器源代码中执行，头部加上`var getToken`;
+
+![请求](./img/6.png)
+
+尾部加上`getToken = __webpack_module_cache__`
+
+![请求](./img/7.png)
+
+在补全`window`全局变量参数
+
+    window.PAGE_START_LOAD_TIME = new Date().getTime();
+    window.LOGIN_UMID_LOAD = true;
+    window.viewConfig = {....},
+    window.viewData = {.....};
+    window._lang = {.....};
+
+控制台测试
+
+    new getToken[1641].exports.default((0)).rsaPassword('123456')
+   
+![请求](./img/8.png)
+
+能成功打印出加密后的值。
+
+**参数：password2**
+
+## 订单确认页面
+
+存在`sign`加密参数
+
+![请求](./img/9.png)
+
+断点定位加密参数位置
+
+![请求](./img/10.png)
+
+这里直接告诉你答案：就是原生md5加密
