Symfony从控制器的配置文件中获取参数

// 在控制器中
use Symfony\Component\DependencyInjection\ContainerInterface;

class MyController extends AbstractController
{
    private $container;

    public function __construct(ContainerInterface $container)
    {
        $this->container = $container;
    }

    public function myAction()
    {
        $paramValue = $this->container->getParameter('my_parameter');
        // 使用 $paramValue
    }
}

use Symfony\Component\HttpFoundation\Response;

class MyController extends AbstractController
{
    /**
     * @var string
     */
    private $paramValue;

    public function __construct($paramValue)
    {
        $this->paramValue = $paramValue;
    }

    public function myAction()
    {
        // 使用 $this->paramValue
        return new Response('Parameter value: ' . $this->paramValue);
    }
}

// 在 services.yaml 中配置
services:
    App\Controller\MyController:
        arguments:
            $paramValue: '%my_parameter%'

# config/services.yaml
parameters:
    my_parameter: 'some_value'

# config/services.yaml
services:
    App\Service\MyService:
        arguments:
            $myParameter: '%my_parameter%'
