Symfony2 -如何设置自定义标题?

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

我想在我的DefaultController中为TWIG模板设置以下标题:

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?

有什么建议吗?

Using the response class:

使用响应类:

use Symfony\Component\HttpFoundation\Response;
$response = new Response();
$response->headers->set('Content-Type', 'text/html');
$response->send();

from this article:

从这篇文章:

CorsListener.php

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

services.yml

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

If its inside controller then use this:

如果它的内部控制器使用这个:

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Response;

class DefaultController extends Controller
{
    public function indexAction()
    {
        ...    
        $response = new Response($xmlContent);
        $response->headers->set('Content-Type', 'xml');
        $response->headers->set('Another-Header', 'header-value');
        return $response;
    }
}

Just replace Content-Type with your header key and xml with value ... etc

用头键替换内容类型，用值替换xml……等

If you are using the render() method of the controller, then you can add the necessary headers like below because render() method returns a Response object:

如果您使用的是控制器的render()方法，那么您可以添加如下所需的头信息，因为render()方法返回一个响应对象:

$response = $this->render('AppBundle:Post:index.html.twig', array('someArgs' => $someArgs));
$response->headers->set('Content-Type', 'text/html');
return $response;
