 一、定义

        1.1 自定义

                用注释定义类为命令行类,再定义领命名字、注释、参数等。

                根据类Hyperf\Command\Command和其父类Symfony\Component\Console\Command\Command,Test1Command重写父类Hyperf\Command\Command::configure(),而symfony\Component\Console\Command\Command中只是定义了configure方法名。

#Hyperf\Command\Command
use Symfony\Component\Console\Command\Command as SymfonyCommand;
abstract class Command extends SymfonyCommand
{
……
    protected function configure()
    {
        parent::configure();
        if (! isset($this->signature)) {
            $this->specifyParameters();
        }
    }
……
    protected function execute(InputInterface $input, OutputInterface $output)
    {
        $this->enableDispatcher($input);
        $callback = function () {
            ……
                call([$this, 'handle']);
            ……
            return 0;
        };

        if ($this->coroutine && ! Coroutine::inCoroutine()) {
            run($callback, $this->hookFlags);
            return $this->exitCode;
        }

        return $callback();
    }
……
}
use Hyperf\Command\Annotation\Command;
use Hyperf\Command\Command as HyperfCommand;

/**
 * @Command
 */
#[Command]
class Test1Command extends HyperfCommand
{
    protected $name = "test:first";
    public function configure()
    {
        parent::configure();
        $this->setDescription('Hyperf Demo Command');
    }
    public function handle()
    {
        $str = "123";
        $this->line($str);
    }
}

        1.2 使用命令行

php bin/hyperf.php gen:command 命令名

       1.3 设置配置文件

        

#config/commands.php
return [
    "App\Command\Test2Command",
];

#App\Command\Test2Command 
namespace App\Command;
use Hyperf\Command\Command as HyperfCommand;

class Test2Command extends HyperfCommand
{
    protected $name = "test:test";

    public function configure()
    {
        parent::configure();
        $this->setDescription('Hyperf Demo Command');
    }

    public function handle()
    {
        $this->line('Hello Hyperf!', 'info');
    }
}


#命令行
php bin/hyperf.php
……
test
  test:first
  test:test           Hyperf Demo Command
    

        1.4 symfony/console 使用

namespace Hyperf\Framework;

use Hyperf\Command\Annotation\Command;
use Hyperf\Contract\ConfigInterface;
use Hyperf\Di\Annotation\AnnotationCollector;
use Hyperf\Framework\Event\BootApplication;
use Psr\Container\ContainerInterface;
use Psr\EventDispatcher\EventDispatcherInterface;
use Symfony\Component\Console\Application;

class ApplicationFactory
{
    public function __invoke(ContainerInterface $container)
    {
        if ($container->has(EventDispatcherInterface::class)) {
            $eventDispatcher = $container->get(EventDispatcherInterface::class);
            $eventDispatcher->dispatch(new BootApplication());
        }

        $config = $container->get(ConfigInterface::class);
        //从配置文件中获取
        $commands = $config->get('commands', []);
        // Append commands that defined by annotation.
        $annotationCommands = [];
        //从设置备注的类中获取
        if (class_exists(AnnotationCollector::class) && class_exists(Command::class)) {
            $annotationCommands = AnnotationCollector::getClassesByAnnotation(Command::class);
            $annotationCommands = array_keys($annotationCommands);
        }

        $commands = array_unique(array_merge($commands, $annotationCommands));
        $application = new Application();

        if (isset($eventDispatcher) && class_exists(SymfonyEventDispatcher::class)) {
            $application->setDispatcher(new SymfonyEventDispatcher($eventDispatcher));
        }

        foreach ($commands as $command) {
            $application->add($container->get($command));
        }
        return $application;
    }
}
