Question

我是symfony的新手，我想在用户登录时返回一个json，但我不知道如何。我正在使用一个带login_check的简单表单来验证我的数据库中的用户，我只想返回这个：

$response = new JsonResponse('borala', 200,  array(
            'Access-Control-Allow-Origin'  => '*',
            'Access-Control-Allow-Headers' => 'Origin, X-Requested-With, Content-Type, Accept',
            'Content-Type' => 'application/json'));

因为login_check是一个幻像＆＃39;实际上并不对应于控制器的路由，您需要使用自定义身份验证处理程序。以下是我完成的工作（简化）：

处理程序

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\RedirectResponse;
use Symfony\Component\HttpFoundation\Session\Session;
use Symfony\Component\Routing\RouterInterface;
use Symfony\Component\Security\Core\Security;
use Symfony\Component\Security\Core\Authentication\Token\TokenInterface;
use Symfony\Component\Security\Core\Exception\AuthenticationException;
use Symfony\Component\Security\Http\Authentication\AuthenticationFailureHandlerInterface;
use Symfony\Component\Security\Http\Authentication\AuthenticationSuccessHandlerInterface;

class AuthenticationHandler implements AuthenticationSuccessHandlerInterface, AuthenticationFailureHandlerInterface
{
    protected $router;
    protected $session;

    public function __construct( RouterInterface $router, Session $session )
    {
        $this->router  = $router;
        $this->session = $session;
    }

    public function onAuthenticationFailure( Request $request, AuthenticationException $exception )
    {
        if( $request->isXmlHttpRequest() )
        {
            $response = new Response( json_encode( array( 'success' => false, 'message' => $exception->getMessage() ) ) );
            $response->headers->set( 'Content-Type', 'application/json' );

            return $response;
        }

        $request->getSession()->set( Security::AUTHENTICATION_ERROR, $exception );

        return new RedirectResponse( $this->router->generate('site_login') );
    }

    public function onAuthenticationSuccess( Request $request, TokenInterface $token )
    {
        if( $request->isXmlHttpRequest() )
        {
            $response = new Response( json_encode( array( 'success' => true ) ) );
            $response->headers->set( 'Content-Type', 'application/json' );

            return $response;
        }

        $url = ( $this->session->get('_security.main.target_path') ) ? $this->session->get('_security.main.target_path') : $this->router->generate('home') ;

        return new RedirectResponse( $url );
    }

将处理程序设置为服务：

security.auth_handler:
    class:      MyNamespace\Service\Security\Listeners\AuthenticationHandler
    public:     false
    arguments:  ['@router','@session']

针对防火墙设置处理程序：

    site:
        ...
        form_login:
            login_path:             /login
            check_path:             /check_login
            success_handler:        security.auth_handler
            failure_handler:        security.auth_handler
        logout:
            path:                   /logout
            target:                 /

在login_check中返回Json
