以一個簡單的例子(中銀E路通小程序)介紹下小程序反編譯操作流程

實驗環境

操作系統:macOS10.13.6
node:v10.8.0
微信開發者工具:Stable v1.02.1910120

前置準備

需要安裝pc端模擬器工具可以選擇網易MuMu,或者其它模擬器
模擬器設置中配置共享文件夾
下載反編譯工具wxAppUnpacker

模擬器內軟件安裝

需要安裝以下兩個軟件

安裝APP

RE文件管理器(查看小程序壓縮包)
微信(使用微信打開小程序以下載小程序包)

獲取小程序包

1.使用自己手機上的微信打開"中銀E路通"小程序,可以添加到"我的小程序"；
2.打開模擬器的微信并登錄；
3.在模擬器微信的下拉小程序最近使用歷史中打開"中銀E路通",如果歷史記錄中沒有就在我的小程序中找一找；
4.打開小程序等待加載之后就可以去找源碼包了；
5.打開RE文件管理器,進入到以下路徑查找源碼包(可以根據下載時間區分出你想要的源碼包)；

/data/data/com.tencent.mm/MicroMsg/4c8188dbf07eec893d0ac90974657aeb/appbrand/pkg

6.拷貝小程序包至模擬器共享文件夾,為了方便解包重命名為zyel

小程序包

獲取完畢。

開始解包

解包流程

1.進入克隆下來的反編譯工具根目錄
如果沒有安裝過npm包就先執行安裝

npm install

2.解包

node wuWxapkg.js <path/to/zyel.wxapkg>

可以看到命令行輸出如下提示

3.如果想單獨執行config、js、wxml、wxss的反編譯可以在解包時加-o參數不做后續操作

工具用法

node wuConfig.js<files...> 將 app-config.json 中的內容拆分到各個文件對應的 .json 和 app.json , 并通過搜索 app-config.json 所在文件夾下的所有文件嘗試將 iconData 還原為 iconPath 。
node wuJs.js<files...> 將 app-service.js (或小游戲中的 game.js ) 拆分成一系列原先獨立的 JAVAscript 文件，并使用 Uglify-ES 美化，從而盡可能還原編譯前的情況。
node wuWxml.js[-m]<files...> 將編譯/混合到 page-frame.html ( 或 app-wxss.js ) 中的 wxml 和 wxs 文件還原為獨立的、未編譯的文件。如果加上 -m指令，就會阻止 block塊自動省略，可能幫助解決一些相關過程的 bug 。
node wuWxss.js<dirs...> 通過獲取文件夾下的 page-frame.html ( 或 app-wxss.js ) 和其他 html 文件的內容，還原出編譯前 wxss 文件的內容。
node wuWxapkg.js[-o][-d][-s=<MainDir>]<files...> 將 wxapkg 文件解包，并將包中上述命令中所提的被編譯/混合的文件自動地恢復原狀。如果加上 -o指令，表示僅解包，不做后續操作。如果加上 -d指令，就會保留編譯/混合后所生成的新文件，否則會自動刪去這些文件。同時，前面命令中的指令也可直接加在這一命令上。
