You have requested a non-existent service "knp_snappy.pdf" - symfony

Question

I followed the tutorial on https://github.com/KnpLabs/KnpSnappyBundle and https://ourcodeworld.com/articles/read/250/how-to-create-a-pdf-from-html-using-knpsnappybundle-wkhtmltopdf-in-symfony-3.
app/config/config.yml
knp_snappy:`enter code here`
pdf:
enabled: true
binary: /usr/local/bin/wkhtmltopdf

app/AppKernel
new Knp\Bundle\SnappyBundle\KnpSnappyBundle(),
MyController
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'
);
}
I try and this:
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"'
)
);
The same problem:
You have requested a non-existent service "knp_snappy.pdf".

Answer 1

/**
* #Route("/{id}/pdf", name="sandbox_pdf", methods={"GET"})
*/
public function pdfAction(\Knp\Snappy\Pdf $snappy, Product $product): Response
{
$html = $this->renderView('pdf/index.html.twig', [
'product' => $product,
]);
$filename = 'product';
return new Response(
$snappy->getOutputFromHtml($html),
200,
array(
'Content-Type' => 'application/pdf',
'Content-Disposition' => 'inline; filename="'.$filename.'.pdf"'
)
);
}

Answer 2

use Knp\Snappy\Pdf;
use Knp\Bundle\SnappyBundle\Snappy\Response\PdfResponse;
/**
* #Route("/show/pdf/{token}", name="admin_invoice_show_pdf", methods={"GET"})
*/
public function showPdf(Command $command, Pdf $pdf)
{
$html = $this->renderView('admin/invoice/showPdf.html.twig',array('command' $command));
return new PdfResponse($pdf->getOutputFromHtml($html), 'invoice.pdf');
}
