您请求了一个不存在的服务“security.context". [英] You have requested a non-existent service "security.context"

问题描述

我创建了服务但它不起作用

服务:重定向监听器:类:FrontEcommerceBundleListenerRedirectionListener参数:["@service_container","@session"]标签:- { 名称:kernel.event_listener，事件:kernel.request，方法:onKernelRequest }

这是我的课

命名空间 FrontEcommerceBundleListener;使用 SymfonyComponentDependencyInjectionContainerBuilder;使用 SymfonyComponentHttpFoundationSessionSession;使用 SymfonyComponentHttpFoundationRedirectResponse;使用 SymfonyComponentHttpKernelEventGetResponseEvent;类重定向监听器{公共函数 __construct(ContainerBuilder $container, Session $session){$this->session = $session;$this->router = $container->get('router');$this->securityContext = $container->get('security.context');}公共函数 onKernelRequest(GetResponseEvent $event){$route = $event->getRequest()->attributes->get('_route');if ($route == 'livraison' || $route == 'validation') {如果 ($this->session->has('panier')) {if (count($this->session->get('panier')) == 0)$event->setResponse(new RedirectResponse($this->router->generate('panier')));}if (!is_object($this->securityContext->getToken()->getUser())) {$this->session->getFlashBag()->add('notification','Vous devez vous identifier');$event->setResponse(new RedirectResponse($this->router->generate('fos_user_security_login')));}}}}

Container.php 第 268 行中的 ServiceNotFoundException:您已请求一个不存在的服务security.context".

解决方案

security.context 服务在 2.6 中被弃用，并拆分为两个新服务:security.authorization_checker 和 security.token_storage.

与之前版本框架的一些不同用法:

//Symfony 2.5$user = $this->get('security.context')->getToken()->getUser();//Symfony 2.6$user = $this->get('security.token_storage')->getToken()->getUser();//Symfony 2.5if (false === $this->get('security.context')->isGranted('ROLE_ADMIN')) { ... }//Symfony 2.6if (false === $this->get('security.authorization_checker')->isGranted('ROLE_ADMIN')) { ... }

i create service but it doesn't work

services:
    redirectionListener:
          class: FrontEcommerceBundleListenerRedirectionListener
          arguments: ["@service_container","@session"]
          tags:
            - { name: kernel.event_listener, event: kernel.request, method: onKernelRequest }

and this my class

namespace FrontEcommerceBundleListener;

use SymfonyComponentDependencyInjectionContainerBuilder;
use SymfonyComponentHttpFoundationSessionSession;
use SymfonyComponentHttpFoundationRedirectResponse;
use SymfonyComponentHttpKernelEventGetResponseEvent;

class RedirectionListener
{
    public function __construct(ContainerBuilder $container, Session $session)
    {
        $this->session = $session;
        $this->router = $container->get('router');
        $this->securityContext = $container->get('security.context');
    }

    public function onKernelRequest(GetResponseEvent $event)
    {
        $route = $event->getRequest()->attributes->get('_route');

        if ($route == 'livraison' || $route == 'validation') {
            if ($this->session->has('panier')) {
                if (count($this->session->get('panier')) == 0)
                    $event->setResponse(new RedirectResponse($this->router->generate('panier')));
            }

            if (!is_object($this->securityContext->getToken()->getUser())) {
                $this->session->getFlashBag()->add('notification','Vous devez vous identifier');
                $event->setResponse(new RedirectResponse($this->router->generate('fos_user_security_login')));
            }
        }
    }
}

ServiceNotFoundException in Container.php line 268: You have requested a non-existent service "security.context".

解决方案

The security.context service was deprecated in the 2.6 and split into two new services: security.authorization_checker and security.token_storage.

Some different usage from the prior version of the framework:

// Symfony 2.5
$user = $this->get('security.context')->getToken()->getUser();
// Symfony 2.6
$user = $this->get('security.token_storage')->getToken()->getUser();

// Symfony 2.5
if (false === $this->get('security.context')->isGranted('ROLE_ADMIN')) { ... }
// Symfony 2.6
if (false === $this->get('security.authorization_checker')->isGranted('ROLE_ADMIN')) { ... }
