Difficultés avec knpSnappy

Version imprimable

Bonjour,

Je tente de générer un fichier pdf contenant une liste de candidats et pour cela j’utilise le bundle knpSnappy.
Je l'ai installé via composer :

composer require knplabs/knp-snappy-bundle

Voici le contenu de app/config/package/knp_snappy.yaml

        binary:     "\"C:\\wkhtmltopdf\\bin\\wkhtmltopdf.exe\""
        options:  
            ## set default settings   
            no-outline: true
            page-size: LETTER
            # recommend to set utf-8 as default encoding
            encoding: UTF-8
    image:
        enabled:    true
        binary:     "\"C:\\wkhtmltopdf\\bin\\wkhtmltoimage.exe\""
        options:    []

A l'exécution j'ai le message d'erreur suivant que je n'arrive pas à comprendre

Citation:

ServiceNotFoundException
HTTP 500 Internal Server Error
Service "knp_snappy.pdf" not found: even though it exists in the app's container, the container inside "App\Controller\VanController" is a smaller service locator that only knows about the "doctrine", "form.factory", "http_kernel", "parameter_bag", "request_stack", "router", "security.authorization_checker", "security.csrf.token_manager", "security.token_storage", "serializer", "session" and "twig" services. Try using dependency injection instead.

Je serais ravi d'avoir des idées pour sortir de ce pétrin. Merci

Bonjour, Il semble que cette ligne pose problème :

Code:

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

Essayez de passer l'objet dans la signature de la méthode :

        $repo = $this->getDoctrine()->getRepository(Candidat::class);      
        $candidat = $repo->findAll();
        //$snappy = $this->get("knp_snappy.pdf");
        //$snappy->setOption("encoding", "UTF-8");

        return new Response(
            $snappy->getOutputFromHtml($html),
            200,
            array(

Merci pour votre réaction. J'ai fait tel que vous avez suggéré mais l'erreur suivante :

Citation:

Cannot determine controller argument for "App\Controller\VanController::listCandidats()": the $snappy argument is type-hinted with the non-existent class or interface: "App\Controller\Knp\Snappy\Pdf". Did you forget to add a use statement?

Est ce que le

Code:

use Knp\Snappy\Pdf;

est toujours présent dans votre controller ?

        //$snappy = $this->get("knp_snappy.pdf");
        //$snappy->setOption("encoding", "UTF-8");
 
        $html = $this->renderView('van/list.html.twig', [
             'candidats'=> $candidat,

          ]);

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

En s'assurant que le use mentionné au début est bien là.

Sinon utilisez l'auto completion de votre IDE pour bien utiliser cette classe.

le

Code:

use Knp\Snappy\Pdf;

existe bien dans le controller.
Et quand je porte cette modif

Code:

public function listCandidats(Request $request, Pdf $snappy)

C'est le message d'erreur qui revient
