Start decompilation

1. Obtain small program PKG package:

Log in to wechat in the simulator and randomly open A small program A

Open the file manager, find/data/data/com. Tencent. The mm/MicroMsg directory, and then find a long

User random code, continue to find /appbrand/ PKG/XXX, next will appear small program A wxapkg package (right-click and select Copy) Find the Android share pathThe paste button is always on top and copies the applet PKG package to the Android shared path so you can access the applet PKG package from your computer2 Install script dependency use CMD CD to the script directory you just downloaded, executenpm installInstall dependencies

3 Run the script command to copy the path of the PKG

node  wuWxapkg.js C:\Users\pc-03\Nox_share\ImageShare\xx.wxapkg

C:\Users\pc-03\Nox_share\ImageShare\xx.wxapkg is my applet path, you need to copy your own applet pathCopy the code

3 Successful Compilation

1, Module build failed: Error: Cannot find Module ‘escodeGen’ NPM I –save-dev escodegen 2, Error: Cannot find module ‘cheerio’ NPM install ugliffe -es –save NPM install esprima –save NPM install CSS-tree –save npm install cssbeautify –save npm install vm2 –save npm install uglify-es –save npm install js-beautify –save npm Install escodeGen –save NPM install cheerio –save 3 undetected packages. Wxapkg file: the decomcompiled package is not the project folder, go to the RE file manager to check whether there is another file. This. Wxapkg is the basic package of wechat, there is no need to restore!! A lot of blogs don’t explain this, so I thought it wasn’t decompiled!

4 SyntaxError: Unexpected end of input solve WXSS missing problem

function runVM(name,code){ let wxAppCode={},handle={cssFile:name}; let gg = new GwxCfg(); let tsandbox = {$gwx:GwxCfg.prototype["$gwx"],__mainPageFrameReady__:GwxCfg.prototype["$gwx"],__wxAppCode__:wxAppCode,setCssToHead:cssR ebuild.bind(handle)}; let vm = new VM({sandbox:tsandbox}); vm.run(code); for(let name in wxAppCode)if(name.endsWith(".wxss")){ handle.cssFile=path.resolve(frameName,".." ,name); wxAppCode[name](); } /* let wxAppCode={},handle={cssFile:name}; let vm=new VM({sandbox:Object.assign(new GwxCfg(),{__wxAppCode__:wxAppCode,setCssToHead:cssRebuild.bind(handle)})}); vm.run(code); for(let name in wxAppCode)if(name.endsWith(".wxss")){ handle.cssFile=path.resolve(frameName,".." ,name); wxAppCode[name](); * /}}Copy the code

Decompile the applet again,OK, WXSS comes out
