Symfony2登录和安全

Question

Is there a way I can store when was the last time a user logged in?

I'm using symfony2, and everything's working alright with the security configuration.

I've seen this Security and login on a Symfony 2 based project , which is a similar question, but it just doesn't fit my needs.

Is there any other solution?

You can create an AuthenticationHandler that Symfony will call when user login successfully, you can save the login time into a User entity property (supposing that you have this scenario).

First, create the success authentication handler:

namespace Acme\TestBundle\Handler;

use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\DependencyInjection\ContainerAware;

class AuthenticationHandler extends ContainerAware implements AuthenticationSuccessHandlerInterface
{
    function onAuthenticationSuccess(Request $request, TokenInterface $token)
    {
        $token->getUser()->setLoginTime(new \DateTime());
        $this->container->get('doctrine')->getEntityManager()->flush();

        return new RedirectResponse($this->container->get('router')->generate('login_success'));
    }
}

Then you need to register the authentication handler as a service in a configuration file, for example, src/Acme/TestBundle/resources/Config/services.yml

services:
    authentication_handler:
        class: Acme\TestBundle\Handler\AuthenticationHandler
        calls:
            - [ setContainer, [ @service_container ] ] 

And configure the login form to use the created handler, check out your security.yml

form_login:
    success_handler: authentication_handler

Obviously, for this to work, you need to have a User entity with a loginTime property and the corresponding setter. And you need to configure the login to use the User entity repository as user provider and the DaoAuthenticationProvider , as explained here: http://symfony.com/doc/current/book/security.html#loading-users-from-the-database .

一个非常简单的解决方案是在您的应用程序中实现FOSUserBundle ，因为数据库中的每个用户条目都包含（其中包括）“last_login”字段。
