有时候在使用php上传安卓apk包的时候,我们需要获取安卓apk包内的信息,本文以实例形式讲述了php获取apk包信息的方法。具体实现方法如下:
<?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 $appobj->getversioncode(); // 版本代码 ?>
以下是apkparser类包,把以下代码复制出来保存为apkparser.php就可以执行以上代码
<?php //------------------------------- //apkparser类包开始 //------------------------------- class apkparser{ //---------------------- // 公共函数,供外部调用 //---------------------- public function open($apk_file, $xml_file='androidmanifest.xml'){ $zip = new \ziparchive; if ($zip->open($apk_file) === true) { $xml = $zip->getfromname($xml_file); $zip->close(); if ($xml){ try { return $this->parsestring($xml); }catch (exception $e){ } } } return false; } public function parsestring($xml){ $this->xml = $xml; $this->length = strlen($xml); $this->root = $this->parseblock(self::axml_file); return true; } public function getxml($node=null, $lv=-1){ if ($lv == -1) $node = $this->root; if (!$node) return ''; if ($node['type'] == self::end_tag) $lv--; $xml = @($node['line'] == 0 || $node['line'] == $this->line) ?
