解决方案

from this 文章：

CorsListener.php

 <？php 
命名空间MyCorp \ MyBundle \Listener; 
 
使用Symfony \Component\HttpKernel\Event \FilterResponseEvent; 
 $ b $ class CorsListener 
 {
 public function onKernelResponse（FilterResponseEvent $ event）
 {
 $ responseHeaders = $ event-> getResponse（） - >头; 
 
 $ responseHeaders-> set（'Access-Control-Allow-Headers'，'origin，content-type，accept'）; 
 $ responseHeaders-> set（'Access-Control-Allow-Origin'，'*'）; 
 $ responseHeaders-> set（'Access-Control-Allow-Methods'，'POST，GET，PUT，DELETE，PATCH，OPTIONS'）; 
} 
} 
  

services.yml

  app.cors_listener：
 class：MyCorp\MyBundle\Listener\CorsListener 
 tags：
  -  {name：kernel.event_listener，event：kernel.response，method：onKernelResponse} 
  

I want to set following Headers for TWIG Template from within my DefaultController:

header('Access-Control-Allow-Methods: GET, POST, OPTIONS');
header('Access-Control-Allow-Credentials: true');
header('Access-Control-Allow-Origin: http://www.mywebsite.com');
header('Access-Control-Allow-Headers: Content-Type, *');

Any suggestions how to do that?
