Symfony 3：FOSSUserBundle獲取JsonResponse而不是重定向

Question

在我的Symnfony3項目中，我注意到在註冊過程中會生成一些事件，我可以重寫響應。例如。而不是呈現默認的樹枝模板和重定向，只是返回一個帶有successMessage的JsonResponse。

所以我做了以下事件訂閱：

namespace AppBundle\EventSubscriber; 

use Symfony\Component\EventDispatcher\EventSubscriberInterface; 
use FOS\UserBundle\FOSUserEvents; 
use FOS\UserBundle\Event\FormEvent; 
use AppBundle\Constants\AjaxJsonResponseConstants; 
use Symfony\Component\HttpFoundation\JsonResponse; 
use FOS\UserBundle\Event\FilterUserResponseEvent; 

class UserRegistrationResponseChanger implements EventSubscriberInterface 
{ 
    public static function getSubscribedEvents() 
    { 
     $subscribedEvents=[ 
//    FOSUserEvents::REGISTRATION_INITIALIZE=>[], 
       FOSUserEvents::REGISTRATION_COMPLETED=>[], 
       FOSUserEvents::REGISTRATION_SUCCESS=>["setJsonResponseOnSuccess",-1], 
       FOSUserEvents::REGISTRATION_FAILURE=>["setJsonResponseOnFailure",-1], 
//    FOSUserEvents::REGISTRATION_CONFIRM=>[], 
//    FOSUserEvents::REGISTRATION_CONFIRMED=>[] 
     ]; 
    } 

    public function setJsonResponseOnSuccess(FormEvent $formEvent) 
    { 
     $response=['status'=>AjaxJsonResponseConstants::AJAX_ACTION_SUCCESS,'message'=>"User Sucessfully Registered please check your mail."]; 
     $response=new JsonResponse($response); 
     $formEvent->setResponse($response); 

     return $response; 
    } 

    public function setJsonResponseOnFailure(FormEvent $formEvent) 
    { 
     $response=['status'=>AjaxJsonResponseConstants::AJAX_ACTION_FAIL,'message'=>"You cannot register please try again later"]; 
     $response=new JsonResponse($response); 
     $formEvent->setResponse($response); 

     return $response; 
    } 
} 

而且我services.yml我已經把以下內容：

app.user_register.subscriber: 
    class: AppBundle\EventSubscriber\UserRegistrationResponseChanger 
    tags: 
    - { name: app.user_register.subscriber } 

和命令

爲了在覆蓋如何響應將得到返回，但不知何故，它不能這樣做，並重定向到默認頁面。我試圖通過Ajax調用來實現註冊，而不是呈現註冊頁面和重定向。

你應該這樣做步驟：

app.user_register.subscriber: 
    class: AppBundle\EventSubscriber\UserRegistrationResponseChanger 
    tags: 
    - { name: kernel.event_subscriber } 

到services.yml：所有的

首先在定義事件訂閱therfore你的用戶會像被定義，你應該使用的kernel.event_subscriber代替app.user_register.subscriber。另外getSubscribedEvents必須返回偵聽器數組。也有FOSUserEvents::REGISTRATION_COMPLETED必須有一個監聽器，即使它沒有實現，如果你不想讓一個監聽器只是評論一樣。

到底你的聽衆shuld實現這樣的：

namespace AppBundle\EventSubscriber; 

use Symfony\Component\EventDispatcher\EventSubscriberInterface; 
use FOS\UserBundle\FOSUserEvents; 
use FOS\UserBundle\Event\FormEvent; 
use AppBundle\Constants\AjaxJsonResponseConstants; 
use Symfony\Component\HttpFoundation\JsonResponse; 
use FOS\UserBundle\Event\FilterUserResponseEvent; 

class UserRegistrationResponseChanger implements EventSubscriberInterface 
{ 
    public static function getSubscribedEvents() 
    { 
     $subscribedEvents=[ 
//    FOSUserEvents::REGISTRATION_INITIALIZE=>[], 
//    FOSUserEvents::REGISTRATION_COMPLETED=>[], 
       FOSUserEvents::REGISTRATION_SUCCESS=>["setJsonResponseOnSuccess",-1], 
       FOSUserEvents::REGISTRATION_FAILURE=>["setJsonResponseOnFailure",-1], 
//    FOSUserEvents::REGISTRATION_CONFIRM=>[], 
//    FOSUserEvents::REGISTRATION_CONFIRMED=>[] 
     ]; 

     return $subscribedEvents; 
    } 

    public function setJsonResponseOnSuccess(FormEvent $formEvent) 
    { 
     $response=['status'=>AjaxJsonResponseConstants::AJAX_ACTION_SUCCESS,'message'=>"User Sucessfully Registered please check your mail."]; 
     $response=new JsonResponse($response); 
     $formEvent->setResponse($response); 

     return $response; 
    } 

    public function setJsonResponseOnFailure(FormEvent $formEvent) 
    { 
     $response=['status'=>AjaxJsonResponseConstants::AJAX_ACTION_FAIL,'message'=>"You cannot register please try again later"]; 
     $response=new JsonResponse($response); 
     $formEvent->setResponse($response); 

     return $response; 
    } 
}

，當你有登記確認（在FOSUserBundle默認行爲）你應該優先考慮REGISTRATION_SUCCESS事件，看到http://symfony.com/doc/master/bundles/FOSUserBundle/controller_events.html#registration-success-listener-with-enabled-confirmation-at-the-same-time

服務定義需求如下所示：

#app/config/services.yml 
app.security_registration_success: 
    class: Path\To\Your\EventListener\RegistrationSuccessListener 
    tags: 
     - { name: kernel.event_subscriber } 

註冊成功偵聽器的示例：

<?php 

declare(strict_types=1); 

namespace Path\To\Your\EventListener; 

use FOS\UserBundle\Event\FormEvent; 
use FOS\UserBundle\FOSUserEvents; 
use Symfony\Component\EventDispatcher\EventSubscriberInterface; 
use Symfony\Component\HttpFoundation\JsonResponse; 

class RegistrationSuccessListener implements EventSubscriberInterface 
{ 
    public static function getSubscribedEvents(): array 
    { 
     return [FOSUserEvents::REGISTRATION_SUCCESS => [['onRegistrationSuccess', -10]]]; 
    } 

    public function onRegistrationSuccess(FormEvent $event): void 
    { 
     $event->setResponse(new JsonResponse()); 
    } 
}
