如何在控制器中調用Command

// src/AppBundle/Controller/SpoolController.php
namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Console\Application;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Console\Input\ArrayInput;
use Symfony\Component\Console\Output\BufferedOutput;
use Symfony\Component\HttpFoundation\Response;

class SpoolController extends Controller
{
    public function sendSpoolAction($messages = 10)
    {
        $kernel = $this->get('kernel');
        $application = new Application($kernel);
        $application->setAutoExit(false);

        $input = new ArrayInput(array(
           'command' => 'swiftmailer:spool:send',
           '--message-limit' => $messages,
        ));
        // 若是你不想輸出使用NullOutput()
        $output = new BufferedOutput();
        $application->run($input, $output);

        // 獲取命令返回的內容
        $content = $output->fetch();

        // 若是你是使用NullOutput;使用new Response("");
        return new Response($content);
    }
}

展示帶色彩的輸出

1. 安裝組件 composer require sensiolabs/ansi-to-html
2. 使用

// src/AppBundle/Controller/SpoolController.php
namespace AppBundle\Controller;

use SensioLabs\AnsiConverter\AnsiToHtmlConverter;
use Symfony\Component\Console\Output\BufferedOutput;
use Symfony\Component\Console\Output\OutputInterface;
use Symfony\Component\HttpFoundation\Response;
// ...

class SpoolController extends Controller
{
    public function sendSpoolAction($messages = 10)
    {
        // ...
        $output = new BufferedOutput(
            OutputInterface::VERBOSITY_NORMAL,
            true // true for decorated
        );
        // ...

        // return the output
        $converter = new AnsiToHtmlConverter();
        $content = $output->fetch();

        return new Response($converter->convert($content));
    }
}
