是否有另一种方法可以在脚本标记中指示 FOSJsRoutingBundle 的路由？

Question

我正在使用 FOSJsRoutingBundle。我在 Twig 模板中链接文件如下：

<script type="text/javascript" src="{{asset('bundles/fosjsrouting/js/router.js') }}"></script>
<script type="text/javascript" src="{{ path('fos_js_routing_js', {"callback": "fos.Router.setData"}) }}"></script>

但是在使用 bundle KnpSnappyBundle 生成 pdf 文件时，我需要绝对指出前面的路线。通过使用 Symfony 2.3，我在使用资产的路径中进行了如下更改：

<script type="text/javascript" src="{{app.request.scheme ~ '://' ~ app.request.httpHost ~ asset('bundles/fosjsrouting/js/router.js') }}"></script>

我的问题是另一条路线给我这个捆绑包的错误。有没有其他的说法？我尝试将与上述相同的方法不起作用，并且使用url 而不是path 不起作用。

这是我遇到的错误：

这是控制器：

public function GenerarPdfFestivosAction()
{

    $this->render(sprintf('BackendBundle:Festivos:calendario.pdf.twig'));
    $em = $this->getDoctrine()->getManager();

    $inicio =$em->getRepository('BackendBundle:Centro')->findInicioCurso();
    $fin =$em->getRepository('BackendBundle:Centro')->findFinCurso();


    $html = $this->renderView('BackendBundle:Festivos:calendario.html.twig', array(
        'inicio' => $inicio,
        'fin' => $fin,
    ));

    return new Response(
        $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
        200,
        array(
            'Content-Type'        => 'application/pdf',
            'Content-Disposition' => 'attachment; filename="Calendario.pdf"'
        )
    );
}

感谢您的帮助。

您的 pdf 已生成，您可以像这样使用它 (answer from here)： 在您的控制器中：

use Symfony\Component\HttpFoundation\BinaryFileResponse;

    function generatePdfAction($param){
       $generator =  $this->get('knp_snappy.pdf');
       $pdf = null;
       $fileName = '/myDir/Calendario.pdf'; // change this
       $inicio =$em->getRepository('BackendBundle:Centro')->findInicioCurso();
       $fin =$em->getRepository('BackendBundle:Centro')->findFinCurso();
       $html = $this->renderView('BackendBundle:Festivos:calendario.html.twig', array(
                'inicio' => $inicio,
                'fin' => $fin,
               ));
       try {
            $pdf = $generator->getOutputFromHtml($html);
        } catch (\RuntimeException $e) {
            $matches = [];
            if (preg_match('/([^\']+)\'.$/', $e->getMessage(), $matches)) {
                $pdf = file_get_contents($matches[1]);
                unlink($matches[1]);
            } else  {
                throw $e;
            }
        }
       if ($pdf){
          file_put_contents($fileName, $pdf);
          return new BinaryFileResponse($fileName);
       }
       else{
       // error message or smthing
       }
    }
