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.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
