php - 无法使用服务注入(inject) SecurityContext

Question

我看过很多关于这个的帖子，但我不明白我做错了什么。

服务.yml:

parameters:

services:
    bar.menu_builder:
        class: Foo\BarBundle\Menu\MenuBuilder
        arguments: [ @security.context ]

菜单生成器:

namespace Foo\BarBundle\Menu;

use Symfony\Component\Security\Core\SecurityContextInterface;
use Knp\Menu\FactoryInterface;

class MenuBuilder {

    protected $securityContext;
    protected $isLoggedIn;

    public function __construct(SecurityContextInterface $securityContext) {
        $this->securityContext = $securityContext;
        $this->isLoggedIn = $this->securityContext->isGranted('IS_AUTHENTICATED_FULLY');
    }

    // other methods
}

但是没有通过SecurityContext，因为我得到了这个异常:

ContextErrorException: Catchable Fatal Error: Argument 1 passed to Foo\BarBundle\Menu\MenuBuilder::__construct() must implement interface Symfony\Component\Security\Core\SecurityContextInterface, none given

任何的想法？

Answer 1

应引用服务参数。

parameters:

services:
    bar.menu_builder:
        class: Foo\BarBundle\Menu\MenuBuilder
        arguments: ["@security.context"]
