kernel.view

• 需要在控制器直接返回值

• 事件监听的实现

    <?php
    namespace BaseBundle\EventListener;
  
    use Symfony\Component\HttpKernel\Event\GetResponseForControllerResultEvent;
  
    class PdfViewListener
    {
        private $templating;
        public function __construct($templating)
        {
            $this->templating = $templating;
        }
        public function preRender(GetResponseForControllerResultEvent $event)
        {
            //result returned by the controller
            $data = $event->getControllerResult();
  
            /* @var $request  \Symfony\Component\HttpFoundation\Request */
            $request =  $event->getRequest();
            $template = $request->get('_template');
            $route = $request->get('_route');
            $format = $request->get('format');
            dump($format);
            dump($request);
            if('pdf' == $format){
                $template = '@Base/Default/base.pdf.twig';
                $data['parameters']['base_view'] = $data['view'];
            }else{
                $template = $data['view'];
            }
            $response = $this->templating->renderResponse($template, $data['parameters']);
            $event->setResponse($response);
        }
    }
  

• 定义

    base.pdf_view_listener:
        class: BaseBundle\EventListener\PdfViewListener
        arguments: ["@templating"]
        tags:
            - { name: kernel.event_listener, event: kernel.view, method: preRender}
