这个解包只能看个或许
1.找到小措施压缩包1.1、手机root或安装模仿器(我用的是夜神)
1.2、在模仿器上安装微信(用android5系统的模仿器，低版本小措施容易打不开)
1.3、打开登岸微信后，打开小措施
1.4、打开模仿器自带的文件打点器来到目次：/data/data/com.tencent.mm/MicroMsg/{{一串32位的16进制字符串文件夹}}/appbrand/pkg/
1.5、内里有许多wxapkg文件，找到最新修他日期的文件好比 -357038350_91.wxapkg，前面打勾选中
1.6、文件打点器回到/mnt/shared/Other目次，粘贴即可，打开安卓模仿器上我的电脑 =〉打开电脑文件夹找到粘贴的文件-357038350_91.wxapkg 夜神教程链接：跳转查察
2.对压缩包解包具体参考：https://codechina.csdn.net/mirrors/leo9960/wechat-app-unpack?utm_source=csdn_github_accelerator
我用的php类：
利用要领：cmd =>cd php文件目次 =〉php wx_unpak.php 357038350_91.wxapkg
我主要是想用个中的一些图片，许多图片都被base64了放到js(app-service.js)和样式(app-wxss.js)文件中了；需要我们匹配组装一下
