php获取apk包信息的类

栏目: PHP · 发布时间: 5年前

内容简介:最近由于公司的需求,需要为游戏的开放平台做一个上传apk的功能其中需要获取包的一些信息,于是在网上扒来了一个获取apk信息的操作类,觉得写的挺好的,所以写下来和大家分享,同时记录一下。由于js无法打开zip包,所以无法通过js来解析apk获取其中的信息,所以我们只能先将包上传到服务器,再用php来操作他(当然java于是可以滴),话补多说,先上代码:调用起来也是相当的简单的:

最近由于公司的需求,需要为游戏的开放平台做一个上传apk的功能其中需要获取包的一些信息,于是在网上扒来了一个获取apk信息的操作类,觉得写的挺好的,所以写下来和大家分享,同时记录一下。

由于js无法打开zip包,所以无法通过js来解析apk获取其中的信息,所以我们只能先将包上传到服务器,再用 php 来操作他(当然 java 于是可以滴),话补多说,先上代码:

//---------------------
//Apkparser类包结束

?>

调用起来也是相当的简单的:

<?php
/*解析安卓apk包中的压缩XML文件,还原和读取XML内容
依赖功能:需要PHP的ZIP包函数支持。*/
include('./Apkparser.php');
$appObj  = new Apkparser(); 
$targetFile = a.apk;//apk所在的路径地址
$res   = $appObj->open($targetFile);
$appObj->getAppName();     // 应用名称
$appObj->getPackage();    // 应用包名
$appObj->getVersionName();  // 版本名称
$appObj->getVersionCode();  // 版本代码
?>

还有其他功能需求的朋友可以看下代码,里面有比较详细的注释。
