Symfony 通过 ajax 重定向

Question

页面登录使用 ajax，在控制器响应中查看 web 浏览器 {"response":true,"data":{"from":"apachecms_api_login_submit","to":"/dashboard"}} 并且不重定向。

成功时的ajax函数

    function beforeSuccess(data){
            if(data.data.from=='apachecms_api_login_recovery_submit'){
                loading.hide();
                $.toast({
                    heading: "{{ 'success' | trans }}",
                    text: "{{ 'forgot.password.sending' | trans }}",
                    position: 'top-right',
                    icon: 'success',
                    hideAfter: 5000, 
                    stack: 10
                });
                changeForm('login')
            }else if(data.data.from=='apachecms_api_login_submit'){
                location.href=data.data.to;
            }else if(data.data.from=='apachecms_api_login_create_submit'){
                location.href=data.data.to;
            }
        }

发生了什么事？

LoginController.php 扩展 BaseController

    public function loginAction(Request $request){
        $form=$this->createForm(LoginType::class, null,array('action'=>$this->generateUrl('apachecms_api_login_submit'),'method' => 'POST'));
        $form->handleRequest($request);
        if($errors=$this->ifErrors($form)) return $errors;
        try {
            $entity = $this->getDoctrine()->getRepository('ApachecmsBackendBundle:Customer')->findOneBy(array('email'=>$form->get('_username')->getData(),'isDelete'=>false));
            if(!$entity)
                throw new Exception(null,200);

            $encoder_service = $this->get('security.encoder_factory');
            $encoder = $encoder_service->getEncoder($entity);
            if(!$encoder->isPasswordValid($entity->getPassword(), $form->get('_password')->getData(), $entity->getSalt()))
                throw new Exception(null,200);

            $token = new UsernamePasswordToken($entity, $form->get('_password')->getData(), "main", $entity->getRoles());
            $this->get("security.token_storage")->setToken($token);
            $event = new InteractiveLoginEvent($request, $token);
            $this->get("event_dispatcher")->dispatch("security.interactive_login", $event);

            return $this->responseOk(array('from'=>'apachecms_api_login_submit','to'=>$this->generateUrl('apachecms_frontend_dashboard'))); // HERE RETURN RESPONSE
        }catch (Exception $excepcion) {
            return $this->responseFail(array(array('property'=>'_username','code'=>'invalid_credentials','message'=>$this->get('translator')->trans('invalid.credentials'),'data'=>null)),200);
        }

    }

BaseController.php

public function responseOk($data=array(),$code=200){
        try{

            return new Response($this->get('jms_serializer')->serialize(
                array('response'=>true,'data'=>$data),
            'json',$this->context),$code);
        }catch (Exception $excepcion) {
            return $this->responseFail(array(array(
                'property'=>null,
                'message'=>$excepcion->getMessage(),
                'code'=>'not_found',
                'data'=>null
            )),$excepcion->getCode());
        }
    }
