下面由Laravel教程栏目给大家介绍实现 laravel 的artisan 的方法，希望对需要的朋友有所帮助！
laravel 的 artisan 命令行太好用了，换个框架没有这个功能，于是自己学习实现一些，直接上代码
新建目录
-artisan
–bin
–src
进入artisan composer init
composer require symfony/console
#!/usr/bin/env php<?phpuse Symfony\Component\Console\Application;use Symfony\Component\Console\Input\InputInterface;use Symfony\Component\Console\Output\OutputInterface;require_once __DIR__.'/../vendor/autoload.php';$app = new Application('artisan','1.1.1');$app->register('artisan')->setCode(function(InputInterface $input, OutputInterface $output){ $output->writeln('artisan start');});$app->run();exit();以上是简单的实现
#!/usr/bin/env php<?phpuse Symfony\Component\Console\Application;use Symfony\Component\Console\Input\InputInterface;use Symfony\Component\Console\Output\OutputInterface;use Symfony\Component\Console\Input\InputArgument;require_once __DIR__ . '/../vendor/autoload.php';$app = new Application('artisan', '1.1.1');$app->register('artisan') ->setDescription('myself artisan description') ->setCode( function (InputInterface $input, OutputInterface $output) { $name = $input->getArgument('name'); $output->writeln("hello {$name}"); } )->addArgument('name', InputArgument::REQUIRED, 'please input your name');$app->run();exit();这里演示了如何接收参数
#!/usr/bin/env php<?phpuse Symfony\Component\Console\Application;use Symfony\Component\Console\Input\InputInterface;use Symfony\Component\Console\Output\OutputInterface;use Symfony\Component\Console\Input\InputArgument;use Symfony\Component\Console\Input\InputOption;require_once __DIR__ . '/../vendor/autoload.php';$app = new Application('artisan', '1.1.1');$app->register('artisan') ->setDescription('myself artisan description') ->setCode( function (InputInterface $input, OutputInterface $output) { $string = $input->getOption('string'); $name = $input->getArgument('name'); if($string == 'lower'){ $name = strtolower($name); } if($string == 'upper'){ $name = strtoupper($name); } $output->writeln("hello {$name}"); } )->addArgument('name', InputArgument::REQUIRED, 'please input your name') ->addOption('string',null,InputOption::VALUE_OPTIONAL,'转换字符串大小','lower');$app->run();exit();这里演示了如何给命令行添加选项 ./bin/artisan.php artisan ffff --string='upper' echo FFFF
$output->writeln("<info>hello {$name}</info>");$output->writeln("<error>hello {$name}</error>");$output->writeln("<comment>hello {$name}</comment>");$output->writeln("hello {$name}");可以给它们加上颜色
接下来将命令行拆分为文件
bin/artisan.php
ArtisanCommand.php
#!/usr/bin/env php<?phpuse Symfony\Component\Console\Application;use Artisan\ArtisanCommand;require_once __DIR__ . '/../vendor/autoload.php';$app = new Application('artisan', '1.1.1');$app->add(new ArtisanCommand());$app->run();exit();ArtisanCommand.php
<?phpnamespace Artisan;use Symfony\Component\Console\Application;use Symfony\Component\Console\Input\InputInterface;use Symfony\Component\Console\Output\OutputInterface;use Symfony\Component\Console\Input\InputArgument;use Symfony\Component\Console\Input\InputOption;use Symfony\Component\Console\Command\Command;class ArtisanCommand extends Command{ public function configure() { $this->setName('artisan'); $this->setDescription('myself artisan description') ->addArgument('name', InputArgument::REQUIRED, 'please input your name') ->addOption('string',null,InputOption::VALUE_OPTIONAL,'转换字符串大小','lower'); } public function execute(InputInterface $input, OutputInterface $output) { $string = $input->getOption('string'); $name = $input->getArgument('name'); if($string == 'lower'){ $name = strtolower($name); } if($string == 'upper'){ $name = strtoupper($name); } $output->writeln("<info>hello {$name}</info>"); $output->writeln("<error>hello {$name}</error>"); $output->writeln("<comment>hello {$name}</comment>"); $output->writeln("hello {$name}"); }}
composer.json
{ "name": "baidu/artisan", "authors": [ { "name": "gaobingbing", "email": "v_gaobingbing01@baidu.com" } ], "require": { "symfony/console": "^4.3" }, "autoload": { "psr-4": { "Artisan\\": "src" } }}至此大功告成，还有其他功能可以去看Symfony文档
