Symfony 注册后如何自动登录用户？

在 Symfony 中注册后自动进行用户身份验证

创建帐户后，最好自动登录用户，而不是要求他们提供自己的信息再次凭证。以下是如何在 Symfony 中实现此目的：

Symfony 4.0

use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use YourNamespace\UserBundle\Entity\User;

class LoginController extends AbstractController
{
    public function registerAction()
    {
        $user = //Handle getting or creating the user entity likely with a posted form
        $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());
        $this->container->get('security.token_storage')->setToken($token);
        $this->container->get('session')->set('_security_main', serialize($token));
        //The user is now logged in, you can redirect or do whatever.
    }
}

Symfony 2.6.x - Symfony 3.0.x

use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use YourNamespace\UserBundle\Entity\User;

class LoginController extends Controller
{
    public function registerAction()
    {
        $user = //Handle getting or creating the user entity likely with a posted form
        $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());
        $this->get('security.token_storage')->setToken($token);
        $this->get('session')->set('_security_main', serialize($token));
    }
}

Symfony 2.3.x

use Symfony\Component\Security\Core\Authentication\Token\UsernamePasswordToken;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use YourNamespace\UserBundle\Entity\User;

class LoginController extends Controller
{
    public function registerAction()
    {
        $user = //Handle getting or creating the user entity likely with a posted form
        $token = new UsernamePasswordToken($user, null, 'main', $user->getRoles());
        $this->get('security.context')->setToken($token);
        $this->get('session')->set('_security_main', serialize($token));
        //Now you can redirect where ever you need and the user will be logged in
    }
}

您需要根据项目的具体配置修改此代码。通过实施这些步骤，您可以确保用户在完成注册过程后自动进行身份验证。
