如何在Zend Expressive中获取Doctrine event subscriber中的用户对象

composer require doctrine/orm

<?php
use Doctrine\Common\EventSubscriber;
use Doctrine\ORM\Event\LifecycleEventArgs;
use YourNamespace\Entity\User;

class UserSubscriber implements EventSubscriber
{
    protected $user;

    public function getSubscribedEvents()
    {
        return ['postLoad'];
    }

    public function postLoad(LifecycleEventArgs $args)
    {
        $entity = $args->getEntity();

        if ($entity instanceof User) {
            $this->user = $entity;
        }
    }

    public function getUser()
    {
        return $this->user;
    }
}

$userSubscriber = $container->get(UserSubscriber::class);
$user = $userSubscriber->getUser();
