如何在数据库中存储用户的最后访问权限 [英] How to store user last access in DB

问题描述

我正在使用Symfony2编写Web应用程序，并且需要注册每个登录到该应用程序的用户的最后访问权限。我的实体具有 last_access 属性，键入datetime。

I'm writing a Web App using Symfony2 and I need to register the last access of every user who log in to the app. My entity has a last_access property, type datetime.

代码很简单，我只需要获取当前用户的实体并设置值，但是我不知道该把代码放在哪里。

The code is easy, I just need to get the entity of the current user and set the value, but I don't know where I have to put that code.

我在想这样的事情：

$manager = $this->getDoctrine()->getManager();
$user= $this->get('security.context')->getToken()->getUser();
$user->setLastAccess(new \DateTime('now'));
$manager->persist($user);
$manager->flush();

UPDATE

我使用事件监听器。

UPDATE

I solved this using an event listener.

class LoginListener {
/**
 * @var Doctrine\Bundle\DoctrineBundle\Registry
 */
private $doctrine;

public function __construct(Doctrine $doctrine){
    $this->doctrine = $doctrine;
}

public function onInteractiveLogin(InteractiveLoginEvent $event){
    $user = $event->getAuthenticationToken()->getUser();

    if ($user) {
        $user->setLastAccess(new \DateTime('now'));
        $this->doctrine->getEntityManager()->persist($user);
        $this->doctrine->getEntityManager()->flush();
    }
}

}

我还创建了一个服务：

services:
my.service:
    class: SGRH\AdminBundle\Listener\LoginListener
    arguments: [@doctrine]
    tags:
      - { name: kernel.event_listener, event: security.interactive_login, method: onInteractiveLogin }

谢谢大家！

推荐答案

您可以对服务进行操作，在登录时调用 security.interactive_login事件。

You can do it with services, at logon the event "security.interactive_login" is invoked.

因此，如果您将YML用于服务：

So if you use YML for services:

your_user_bundle.security.interactive_login_listener:
    class: ACME\YourBundle\Listener\InteractiveLoginListener
    arguments: [ "@doctrine.orm.entity_manager", "@request" ]
    scope: request
    tags:
      - { name: kernel.event_listener, event: security.interactive_login, method: onSecurityInteractiveLogin } 

和类：

<?php

namespace ACME\YourBundle\Listener;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;

use Doctrine\ORM\EntityManager;
use ACME\YourBundle\Entity\User;

class InteractiveLoginListener {

    protected $em;
    protected $request;

    public function __construct(EntityManager $em, Request $request) {

        $this->em = $em;
        $this->request = $request;
    }

    public function onSecurityInteractiveLogin(InteractiveLoginEvent $event) {

        $user = $event->getAuthenticationToken()->getUser();

        if ($user instanceof User) {
            if($this->request->hasSession()) {
                $user->setLastAccess(new \DateTime('now'));
                $this->em->persist($user);
                $this->em->flush();
            }
        }
    }
}
