实现 laravel 的artisan

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

use 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

use 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

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;

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

$output->writeln("hello {$name}");

$output->writeln("hello {$name}");

$output->writeln("hello {$name}");

$output->writeln("hello {$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

use 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

namespace 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);

        }

        $output->writeln("hello {$name}");

        $output->writeln("hello {$name}");

        $output->writeln("hello {$name}");

        $output->writeln("hello {$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
