Question

我遵循了https://github.com/KnpLabs/KnpSnappyBundle和https://ourcodeworld.com/articles/read/250/how-to-create-a-pdf-from-html-using-knpsnappybundle-wkhtmltopdf-in-symfony-3上的教程。

应用程序/配置/ config.yml

knp_snappy:`enter code here`
pdf:
    enabled: true
    binary: /usr/local/bin/wkhtmltopdf
    options: []
image:
    enabled: true
    binary: /usr/local/bin/wkhtmltoimage
    options: []

应用程序/ AppKernel

new Knp\Bundle\SnappyBundle\KnpSnappyBundle(),

myController的

use Knp\Bundle\SnappyBundle\Snappy\Response\PdfResponse;

public function pdfAction(string $offerId)
{
    $html = $this->renderView('@App/Offer/offer_pdf.html.twig', array(
        'offerId'  => $offerId
    ));

    return new PdfResponse(
        $this->get('knp_snappy.pdf')->getOutputFromHtml($html),
        'file.pdf'
    );
}

我试着这个：

 public function offerToPDFAction(string $offerId)
{

    $snappy = $this->container->get('knp_snappy.pdf');

    $html = '<h1>Hello</h1>';

    $filename = 'myFirstSnappyPDF';

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