由于我无法对帖子发表评论,我仍然想通过这个答案对Mick的回答发表评论.

从Symfony 2.6开始,不推荐使用SecurityContext类,在这种情况下,应该使用TokenStorage类.

因此,services.yml将如下:

services:
    acme_user.activity_listener:
        class: %acme_user.activity_listener.class%
        arguments: ['@security.token_storage', '@doctrine.orm.entity_manager']
        tags:
            - { name: kernel.event_listener, event: kernel.controller, method: onCoreController }

并且,而不是

use Symfony\Component\Security\Core\SecurityContext;

一个应该

use Symfony\Component\Security\Core\Authentication\Token\Storage\TokenStorage;

(还用TokenStorage类替换类中的SecurityContext)

然后,在第38行,将使用检查令牌可用性

$this->tokenStorage->getToken()

并且,在第39行,将使用获得用户实例

$this->tokenStorage->getToken()->getUser()

这里有一个很棒的帖子:列出在线用户.

您可以创建侦听kernel.controller事件的侦听器,并在每次用户处于活动状态时更新用户字段lastActivity.您可以检查lastActivity < now()- 2 minutes并更新lastActivity时间戳.

另外:在symfony 2中实现用户活动

这是怎么做的

注意:如果您未使用FOSUserBundle,请参阅下面的编辑.

1 将此添加到您的用户实体

/**
 * Date/Time of the last activity
 *
 * @var \Datetime
 * @ORM\Column(name="last_activity_at", type="datetime")
 */
protected $lastActivityAt;

/**
 * @param \Datetime $lastActivityAt
 */
public function setLastActivityAt($lastActivityAt)
{
    $this->lastActivityAt = $lastActivityAt;
}

/**
 * @return \Datetime
 */
public function getLastActivityAt()
{
    return $this->lastActivityAt;
}

/**
 * @return Bool Whether the user is active or not
 */
public function isActiveNow()
{
    // Delay during wich the user will be considered as still active
    $delay = new \DateTime('2 minutes ago');

    return ( $this->getLastActivityAt() > $delay );
}

2 创建事件监听器

<?php
namespace Acme\UserBundle\EventListener;

use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\HttpKernel\HttpKernel;
use FOS\UserBundle\Model\UserManagerInterface;
use FOS\UserBundle\Model\UserInterface;

/**
 * Listener that updates the last activity of the authenticated user
 */
class ActivityListener
{
    protected $securityContext;
    protected $userManager;

    public function __construct(SecurityContext $securityContext, UserManagerInterface $userManager)
    {
        $this->securityContext = $securityContext;
        $this->userManager = $userManager;
    }

    /**
    * Update the user "lastActivity" on each request
    * @param FilterControllerEvent $event
    */
    public function onCoreController(FilterControllerEvent $event)
    {
        // Check that the current request is a "MASTER_REQUEST"
        // Ignore any sub-request
        if ($event->getRequestType() !== HttpKernel::MASTER_REQUEST) {
            return;
        }

        // Check token authentication availability
        if ($this->securityContext->getToken()) {
            $user = $this->securityContext->getToken()->getUser();

            if ( ($user instanceof UserInterface) && !($user->isActiveNow()) ) {
                $user->setLastActivityAt(new \DateTime());
                $this->userManager->updateUser($user);
            }
        }
    }
}

3 将事件侦听器声明为服务

parameters:
    acme_user.activity_listener.class: Acme\UserBundle\EventListener\ActivityListener

services:
    acme_user.activity_listener:
        class: %acme_user.activity_listener.class%
        arguments: [@security.context, @fos_user.user_manager]
        tags:
            - { name: kernel.event_listener, event: kernel.controller, method: onCoreController }

你很高兴去!

1 将此添加到您的用户实体

Same as Step 1 Above

2 创建事件监听器

<?php
namespace Acme\UserBundle\EventListener;

use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpKernel\Event\FilterControllerEvent;
use Symfony\Component\HttpKernel\HttpKernel;
use Doctrine\ORM\EntityManager;
use Acme\UserBundle\Entity\User;

/**
 * Listener that updates the last activity of the authenticated user
 */
class ActivityListener
{
    protected $securityContext;
    protected $entityManager;

    public function __construct(SecurityContext $securityContext, EntityManager $entityManager)
    {
        $this->securityContext = $securityContext;
        $this->entityManager = $entityManager;
    }

    /**
    * Update the user "lastActivity" on each request
    * @param FilterControllerEvent $event
    */
    public function onCoreController(FilterControllerEvent $event)
    {
        // Check that the current request is a "MASTER_REQUEST"
        // Ignore any sub-request
        if ($event->getRequestType() !== HttpKernel::MASTER_REQUEST) {
            return;
        }

        // Check token authentication availability
        if ($this->securityContext->getToken()) {
            $user = $this->securityContext->getToken()->getUser();

            if ( ($user instanceof User) && !($user->isActiveNow()) ) {
                $user->setLastActivityAt(new \DateTime());
                $this->entityManager->flush($user);
            }
        }
    }
}

3 将事件侦听器声明为服务

parameters:
    acme_user.activity_listener.class: Acme\UserBundle\EventListener\ActivityListener

services:
    acme_user.activity_listener:
        class: %acme_user.activity_listener.class%
        arguments: [@security.context, @doctrine.orm.entity_manager]
        tags:
            - { name: kernel.event_listener, event: kernel.controller, method: onCoreController }

你很高兴去!
