Php 自动注册后用户身份验证

Symfony 4.0个

这个过程没有从Symfony 3更改为4，但下面是一个使用新推荐的AbstractController的示例.security.token_storage和session服务都在父getSubscribedServices方法中注册，因此您不必在控制器中添加这些服务.

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

从symfony 2.6开始，security.context已弃用，取而代之的是security.token_storage.控制器现在可以简单地执行以下操作:

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));
    }

}

虽然这是不推荐的，但您仍然可以使用security.context，因为它已被设置为向后兼容.准备好为Symfony 3更新它.

您可以在此处阅读有关2.6版安全更改的更多信息:https://github.com/symfony/symfony/blob/2.6/UPGRADE-2.6.md

Symfony 2.3.x个

要在symfony 2.3中实现这一点，您不能再仅仅在安全上下文中设置令牌.您还需要将令牌保存到会话.

假设安全文件带有防火墙，如:

// app/config/security.yml
security:
    firewalls:
        main:
            //firewall settings here

控制器动作类似于:

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
    }

}

对于令牌创建，您需要创建一个UsernamePasswordToken.这接受4个参数:用户实体、用户凭据、防火墙名称、用户角色.您不需要提供令牌有效的用户凭据.

如果你只是想马上重定向，我不能security.context%确定是否有必要将令牌设置为security.context.但它似乎不疼，所以我把它留下了.

然后是重要的部分，设置会话变量.变量命名约定是_security_后跟防火墙名称，在本例中是main加_security_main.
