我尝试设置服务以从我的数据库中检索实体.我的services.yml看起来像这样:

app.twig_global_extension:
    class: AppBundle\Twig\GlobalExtension
    arguments: [ "@doctrine.orm.entity_manager", "@security.token_storage" ]
    tags:
        - { name: twig.extension }

我的GlobalExtension是这样的:

<?php
namespace AppBundle\Twig;

class GlobalExtension extends \Twig_Extension
{
    protected $em;
    protected $token_storage;

    public function __construct(\Doctrine\ORM\EntityManager $em, \Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage $token_storage)
    {
        $this->em = $em;
        $this->token_storage = $token_storage;
    }


    public function getGlobals()
    {
        return [
            'userdata' => $this->em->getRepository('AppBundle:userdata')->findOneBy(['internalid' => $this->token_storage->getToken()->getUser()->getId()]),
        ];
    }

    public function getName()
    {
        return 'app_global_extension';
    }
}

它检索正确的实体,但我的Profiler在页面加载完成后抛出错误:

BadMethodCallException in GlobalExtension.php line 18:
Call to a member function getUser() on a non-object (null)

首先,在这种情况下问题是什么？ …
