【【16期】加速乐（下）加密解剖--"某信息化平台"爬虫js逆向·实战教程】
```javascript
https://www.bilibili.com/video/BV1n54y1T7oY
```

- 项目地址
```javascript
https://github.com/yufeng8/decodeObfuscator
```

## 一.环境安装

在nodejs官网下载最新稳定版并安装:  
![](https://files.mdnice.com/user/44292/3504ffea-a341-4dcb-b223-4453f71a836d.png)
下载地址:

```javascript
https://nodejs.org/en/
```

安装成功后，在命令行模式输入 node，如果有版本号显示，则表示安装成功。

## 二.下载项目

项目地址:

```javascript
https://github.com/Tsaiboss/decodeObfuscator
```

目录结构如下:

![](https://files.mdnice.com/user/44292/f0f72686-c5a0-4cd7-96fa-19c3b3bda966.png)

- input文件夹，   存放ob混淆代码;

- output文件夹，存放还原后的代码;

- tools,存放打包的babel库以及部分还原的AST插件;

- main.js   运行主文件;

## 三.运行看结果

下载后解压，切换到 decodeObfuscator-main 目录，命令行模式下运行:

```nginx
node main.js
```

运行时，会打印一些日志，结果文件在output文件夹，打开后是这样的:

## 四.其它混淆代码

打开 obfuscator 官网：

```javascript
https://obfuscator.io/
```

如图选择 **Medium** 级别，再点击上面的 Obfuscate 按钮，生成混淆代码:
![](https://files.mdnice.com/user/44292/7c2f3418-c09c-441c-b6c4-4353c2696a9e.png)

我这里生成的混淆代码是这样的:

```

把上面的混淆代码保存为js文件$命名为Medium.js$，并编码为UTF-8模式。存放在 main.js 统一目录，运行命令:

```css
 node main.js Medium.js
```

运行后，同样可以在 output 文件夹看到还原后的结果。  
  
当然，你还可以指定生成的文件名，如下命令:

```css
node main.js Medium.js 666.js
```

可以发现，在main.js的同级目录新生成了一个 666.js文件，这就是还原后的文件。  
好了，脚本的使用就介绍到这里，希望各位大佬们不要吝惜你的star，帮忙点一个，感谢！
