Symfony 2.8：从2.7.7更新到2.8.0后isScopeActive弃用

Question

I've updated to symfony 2.8 from 2.7.7 and i get this deprecation:

The Symfony\\Component\\DependencyInjection\\Container::isScopeActive method is deprecated since version 2.8 and will be removed in 3.0.

I use this call in a twig extension class:

class TemplateHelper extends \Twig_Extension {

    private $request;

    private $container;


    /**
     * constructor
     * @param ContainerInterface $container
     */
    public function __construct(ContainerInterface $container){
        $this->container = $container;

        if( $this->container->isScopeActive('request') ){
            $this->request = $this->container->get('request');
        }
    }
    //...functions
    }

Firstly i delete the isScopeActive check, but i get an exception when i run the symfony cache clear:

[Symfony\\Component\\DependencyInjection\\Exception\\InactiveScopeException] You cannot create a service ("request") of an inactive scope ("request").

Is there any way to replace the isScopeActive check?

Thanks...

只需注入request_stack而不是request并调用getCurrentRequest（） 。
