这个解包只能看个大概
1.找到小程序压缩包
1.1、手机root或安装模拟器(我用的是夜神)
1.2、在模拟器上安装微信(用android5系统的模拟器,低版本小程序容易打不开)
1.3、打开登陆微信后,打开小程序
1.4、打开模拟器自带的文件管理器来到目录:/data/data/com.tencent.mm/MicroMsg/{{一串32位的16进制字符串文件夹}}/appbrand/pkg/
1.5、里面有很多wxapkg文件,找到最新修改日期的文件比如 -357038350_91.wxapkg,前面打勾选中
1.6、文件管理器回到/mnt/shared/Other目录,粘贴即可,打开安卓模拟器上我的电脑 =〉打开电脑文件夹找到粘贴的文件-357038350_91.wxapkg 夜神教程链接:跳转查看
2.对压缩包解包
详细参考:https://codechina.csdn.net/mirrors/leo9960/wechat-app-unpack?utm_source=csdn_github_accelerator
我用的php类:
使用方法:cmd =>cd php文件目录 =〉php wx_unpak.php 357038350_91.wxapkg
我主要是想用其中的一些图片,很多图片都被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
<?php
$str = file_get_contents('_-357038350_97.wxapkg.unpacked/app-service.js');
$preg = '/(data:image.*?)\"/';
$len = strlen('data:image/png;base64,');
if(preg_match_all($preg, $str, $arr)){
foreach($arr[1] as $k => $img){
file_put_contents('./images/'.$k.'.png',base64_decode(substr($img,$len)));
//echo substr($img,$len);exit;
}
} else {
echo 'no';
}
$str = file_get_contents('_-357038350_97.wxapkg.unpacked/app-wxss.js');
$preg = '/\((data:image.*?)\)/';
$len = strlen('data:image/png;base64,');
if(preg_match_all($preg, $str, $arr)){
foreach($arr[1] as $k => $img){
file_put_contents('./images/a2_'.$k.'.png',base64_decode(substr($img,$len)));
//echo substr($img,$len);exit;
}
} else {
echo 'no';
}
wx_unpak.php
