10分钟带你学会微信小程序的反编译 _反编译

以一个简单的例子(中银E路通小程序)介绍下小程序反编译操作流程实验环境

操作系统:macOS10.13.6
node:v10.8.0
微信开发者工具:Stable v1.02.1910120

前置准备

需要安装pc端模拟器工具可以选择网易MuMu,或者其它模拟器
模拟器设置中配置共享文件夹
下载反编译工具wxAppUnpacker

模拟器内软件安装
需要安装以下两个软件

安装APP

RE文件管理器(查看小程序压缩包)
微信(使用微信打开小程序以下载小程序包)

获取小程序包
1.使用自己手机上的微信打开"中银E路通"小程序,可以添加到"我的小程序"；
2.打开模拟器的微信并登录；
3.在模拟器微信的下拉小程序最近使用历史中打开"中银E路通",如果历史记录中没有就在我的小程序中找一找；
4.打开小程序等待加载之后就可以去找源码包了；
5.打开RE文件管理器,进入到以下路径查找源码包(可以根据下载时间区分出你想要的源码包)；
/data/data/com.tencent.mm/MicroMsg/4c8188dbf07eec893d0ac90974657aeb/appbrand/pkg6.拷贝小程序包至模拟器共享文件夹,为了方便解包重命名为zyel

小程序包
获取完毕。
开始解包
解包流程
1.进入克隆下来的反编译工具根目录
如果没有安装过npm包就先执行安装
npm install2.解包
node wuWxapkg.js <path/to/zyel.wxapkg>可以看到命令行输出如下提示
