php读取apk包信息,提取应用图标
项目中需要在客户上传APK后自动分析出APK包名\名称等信息,并提取出应用的图标,并立即返回到服务端 .试了很多方法,都很难满足需求,其中最知名的应该是ApkParser,但它不能得到应用图标信息;另外还有推荐使用apktool进行反编译apk包,但速度太慢,解一个包大概要5秒以上,不适合做实时程序.我的最终方案是:1 用aapt读取包信息aapt dump badging ./xxx.apkaapt包含在android sdk中的build-tools文件夹,可以把这个文件拷到服务器上单独使用,大小仅1.2M;需要注意的一点是,该程序是32位环境的程序,64位系统运行可能需要安装大概三个扩展包(如果本身没有的话),我服务器CentOS可以直接运行,就不细说了该命令执行很快,瞬间. PHP实时返回数据没问题这里返回的信息中就已经包含了包名\APP名称 及应用图标在apk包中的位置(类似res/drawable-mdpi/icon.png).命令行返回的信息是纯文本,PHP不能直接用,我下面的PHP源码中会将其转为数组,以方便使用2 用unzip直接提取需要的图标文件#解压apk包中指定图片unzip ./xxx.apk res/drawable-mdpi/icon.png -d /tmp#将解压出来的图片移到我们需要的位置mv /tmp/res/drawable-mdpi/icon.png /tmp/temp.png因为apk本身就是zip文件重命名而已,所以无需改名,可以直接解压. 另unzip可以指定只解压压缩包中某文件,也省了很多资源.3 最后就是在PHP中用exec执行这些命令行了,参见下面源码/*** Android包处理程序* Class Service_Android** @author:wangshuai* @website:www.enjoyphp.com*/class Service_Android{ /** * 获取Apk包信息 * * 需要/usr/bin/aapt * * @param $apkFile * @return array */ public function getApkInfo($apkFile) { try { exec('/usr/bin/aapt dump badging ' . $apkFile, $out, $return); $apkInfo = array(); foreach ($out as $line) { $lineana = array(); $a = explode(":", $line); $key = trim($a[0]); $value = trim($a[1]); preg_match_all('/((?P<key>\S+)=)?\'(?P<value>.*?)\'/', $value, $matches, PREG_SET_ORDER); foreach ($matches as $match) { if ($match['key']) { $lineana[$match['key']] = $match['value']; } else { $lineana[] = $match['value']; } } $apkInfo[$key][] = $lineana; } //checkRet会把上面读出来的配置整理一下 $ret = $this->checkRet($apkInfo); } catch (Exception $e) { echo $e->getMessage(); $ret = array(); } return $ret; } /** * 从Apk包中提取指定文件,并移到$toFile * * @param $apkFile apk文件 * @param $sourceFile apk文件中相应文件路径 * @param $toFile 输出文件 * @return bool */ function getFileFromApk($apkFile, $sourceFile, $toFile) { exec('unzip ' . $apkFile . ' $sourceFile -d /tmp', $out, $return); if (rename("/tmp/" . $sourceFile, $toFile)) { return true; } else { return false; } } /** * 辅助函数,处理Apk信息数组 * * @param $info * @return mixed */ function checkRet($info) { foreach ($info as $key => $lineana) { if (is_array($lineana)) { $info[$key] = $this->checkRet($lineana); if (count($info[$key]) == 1) { $info[$key] = current($info[$key]); } } else { } } return $info; }} 一段使用示例:<?php$apk = "/tmp/wht.apk";$iconFile = '/tmp/a.png';/** @var Service_Android $android */$android = new Service_Android();$res = $android->getApkInfo($apk);var_dump($res);$packageName = $res['package']['name'];$appName = $res['application-label']; $android->getFileFromApk($apk,$res['application']['icon'],$iconFile);注意事项:1 运行该程序需要PHP有exec权限2 获取的apk包信息中,APP名称可能会有多国语言名称,ICON会有多种尺寸; 如果有需要,请自行根据需要修改,上面只介绍了使用默认信息.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
