Symfony 2.3登录表单未进行身份验证

Question

I'm trying to implement a rather basic login form with Symfony2.3, but I'm running into an error where I'm sometimes redirected to the expected page after providing correct credentials, but sometimes not (instead I'm just redirected back to the login page). Here is my security.yml file:

security:
    encoders:
        Symfony\Component\Security\Core\User\User: plaintext
        Acme\MyBundle\Entity\User: sha512
    providers:
        main:
            id: acme.user.provider
    firewalls:
        dev:
            pattern: ^/(_(profiler|wdt)|css|images|js)/
            security: false
        login_firewall:
            pattern: ^/login$
            security: false
        secured_area:
            pattern: ^/
            form_login: ~
            logout:
                path:   /logout
                target: /
    access_control:
        - { path: ^/login$, roles: IS_AUTHENTICATED_ANONYMOUSLY, requires_channel: https }
        - { path: ^/, roles: ROLE_USER, requires_channel: https }

Here is my SecurityController:

<?php

namespace Acme\MyBundle\Controller;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Template;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Security\Core\SecurityContextInterface;

/**
 * Class SecurityController
 * @package Acme\MyBundle\Controller
 *
 * @Route("/")
 */
class SecurityController extends Controller
{
    /**
     * @param Request $request
     * @return \Symfony\Component\HttpFoundation\Response
     *
     * @Route("/login", requirements={"_scheme" = "https"}, path="login")
     */
    public function LoginAction(Request $request)
    {
        $session = $request->getSession();

        // get the login error if there is one
        if ($request->attributes->has(SecurityContextInterface::AUTHENTICATION_ERROR)) {
            $error = $request->attributes->get(
                SecurityContextInterface::AUTHENTICATION_ERROR
            );
        } elseif (null !== $session && $session->has(SecurityContextInterface::AUTHENTICATION_ERROR)) {
            $error = $session->get(SecurityContextInterface::AUTHENTICATION_ERROR);
            $session->remove(SecurityContextInterface::AUTHENTICATION_ERROR);
        } else {
            $error = '';
        }

        // last username entered by the user
        $lastUsername = (null === $session) ? '' : $session->get(SecurityContextInterface::LAST_USERNAME);

        return $this->render(
            'AcmeMyBundle:Security:login.html.twig',
            array(
                // last username entered by the user
                'last_username' => $lastUsername,
                'error'         => $error,
            )
        );
    }

    /**
     * @Route("/login_check", requirements={"_scheme" = "https"}, path="login_check")
     */
    public function LoginCheckAction()
    {

    }

    /**
     * @Route("/logout", requirements={"_scheme" = "https"}, path="logout")
     */
    public function LogoutAction()
    {

    }
}

And here is my bundle's routing.yml file:

_security:
    resource: "@AcmeMyBundle/Controller/SecurityController.php"
    type: annotation

When I provide the proper credentials, I'm correctly logged in / redirected to the given URL about 20% of the time. The other 80% of the time I'm just redirected back to the form login page with no error message. I also don't see any error message when I try to login with incorrect credentials.

UPDATE: It looks like the issue is that Symfony is creating more than one session in my database on each request. I am using the pdo handler.

Answer 1

Turns out the issue was actually with the Session entity / table in which I was storing my session. I was using the PDOSessionHandler to store sessions in the database, and had the following $id in my ORM Session entity:

<?php

namespace Acme\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Session
 *
 * @ORM\Table()
 * @ORM\Entity
 */
class Session
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

The $id should not have been of type integer, but (obviously (-_-) of type string. After changing the property to:

/**
 * @var integer
 *
 * @ORM\Column(type="string", length=255)
 * @ORM\Id
 */
private $id;

and running php app/console doctrine:schema:update --force, everything appears to be working correctly.
