php - Symfony 2.8 : isScopeActive deprecation after update to 2. 8.0 来自 2.7.7

Question

我已经从 2.7.7 更新到 symfony 2.8，我得到了这个弃用:

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

我在 twig 扩展类中使用这个调用:

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
    }

首先我删除了 isScopeActive 检查，但是当我运行 symfony 缓存清除时我得到一个异常:

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

有什么方法可以替代 isScopeActive 检查吗？

谢谢...

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