Symfony 如何返回所有登录的活跃用户-php问题

Symfony how to return all logged in Active Users(Symfony 如何返回所有登录的活跃用户)

本文介绍了Symfony 如何返回所有登录的活跃用户的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我想返回我的应用程序的所有登录用户，并将其呈现在我的仪表板中.user_id 和 user_name 应该从会话中检索(我使用外部 LDAP 库进行身份验证)

I want to return all Logged in users of my application and render it in my Dashboard. The user_id and user_name should be retrieved from the session (I am using an external LDAP Library for authentication)

我在数据库中创建了一个名为 lastActivity 的字段，该字段将包含上次登录时间，然后我可以在数据库中查询 lastActivity 显示上次登录的用户2分钟.

I have created a field in the database called lastActivity which will contain the last login time and then I can query the database for lastActivity display users logged in in the last 2 minutes.

ActivityListener.php

     <?php

namespace BnppSecurityBundleEventListener;

use DoctrineORMEntityManager;
//use SymfonyComponentSecurityCoreUserUserInterface;
use SymfonyComponentSecurityCoreSecurityContext;
use SymfonyComponentHttpKernelEventFilterControllerEvent;
use SymfonyComponentHttpKernelHttpKernel;
use AcmeSecurityBundleEntityUser;
use DoctrineBundleDoctrineBundleRegistry;


/**
 * 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->setLastActivity(new DateTime('now'));
                $this->entityManager->flush($user);
            }
        }

    }

}

Services.yml

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

用户实体

<?php

namespace AcmeSecurityBundleEntity;

use DoctrineORMMapping as ORM;
use SymfonyComponentSecurityCoreUserUserInterface;

/**
 * User
 *
 * @ORMTable(name="users")
 * @ORMEntity(repositoryClass="AcmeSecurityBundleEntityUserRepository")
 */
class User implements UserInterface
{

/**
     * @var DateTime
     * @ORMColumn(name="LASTACTIVITY", type="datetime")
     */
    private $lastActivity;


    /**
     * @return bool whether the user is active or not
     */

    public function isActiveNow()
     {

    $delay = newDateTime('2 minutes ago');

    return($this->getlastActivity()>$delay);

       }

/**
     * Set lastActivity
     *
     * @paramDatetime $lastActivity
     * @return User
     */


    public function setlastActivity($lastActivity)
    {
        $this->lastActivity = $lastActivity;

        return $this;
    }


    /**
     * Get lastActivity
     *
     * @return DateTime
     */
    public function getlastActivity()
    {
        return $this->lastActivity;
    }




}

推荐答案

这里有一个很棒的帖子:列出在线用户.

There is a great post here: List online users.

您可以创建一个侦听器来侦听 kernel.controller 事件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 分钟 并更新 lastActivity 时间戳.

You can create a Listener that listens on the kernel.controller event and updates a user field lastActivity every time a user is active. You can check lastActivity < now()- 2 minutes and update lastActivity timestamp.

另外:在 symfony 2 中实现用户活动

注意:如果您没有使用 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
 * @ORMColumn(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 AcmeUserBundleEventListener;

use SymfonyComponentSecurityCoreSecurityContext;
use SymfonyComponentHttpKernelEventFilterControllerEvent;
use SymfonyComponentHttpKernelHttpKernel;
use FOSUserBundleModelUserManagerInterface;
use FOSUserBundleModelUserInterface;

/**
 * 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 将事件监听器声明为服务

parameters:
    acme_user.activity_listener.class: AcmeUserBundleEventListenerActivityListener

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 }

一切顺利！

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 AcmeUserBundleEventListener;

use SymfonyComponentSecurityCoreSecurityContext;
use SymfonyComponentHttpKernelEventFilterControllerEvent;
use SymfonyComponentHttpKernelHttpKernel;
use DoctrineORMEntityManager;
use AcmeUserBundleEntityUser;

/**
 * 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 将事件监听器声明为服务

parameters:
    acme_user.activity_listener.class: AcmeUserBundleEventListenerActivityListener

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 }

一切顺利！
