Symfony2 - how can I set custom CORS Headers?
提问by Edge
I want to set following Headers for TWIG Template from within my DefaultController:
我想从我的 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?
任何建议如何做到这一点？

从这篇文章：
CorsListener.php
监听器.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
服务.yml
app.cors_listener:
class: MyCorp\MyBundle\Listener\CorsListener
tags:
- { name: kernel.event_listener, event: kernel.response, method: onKernelResponse }

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();

If its inside controller then use this:
如果它的内部控制器然后使用这个：
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
只需将 Content-Type 替换为您的标题键，并将 xml 替换为值 ... 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:
如果您正在使用render()控制器的方法，那么您可以添加如下必要的标题，因为render()方法返回一个 Response 对象：
$response = $this->render('AppBundle:Post:index.html.twig', array('someArgs' => $someArgs));
$response->headers->set('Content-Type', 'text/html');
return $response;
