Symfony2-如何设置自定义CORS标头？ [英] Symfony2 - how can I set custom CORS Headers?

问题描述

我想在我的DefaultController中设置以下TWIG模板标题：

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, *');

任何建议如何做？

推荐答案

来自这篇文章：

CorsListener.php

<?php
namespace MyCorp\MyBundle\Listener;

use Symfony\Component\HttpKernel\Event\FilterResponseEvent;

class CorsListener
{
    public function onKernelResponse(FilterResponseEvent $event)
    {   
        $responseHeaders = $event->getResponse()->headers;

        $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 }
