Symfony 3 - VichUploader使用控制器提供文件

I use Symfony 3.4 with PHP 5.6.

I want to use the vichuploader Bundle to download files. I managed to make it work normally. But now I want to be able to use the files directly from the controller to be able to use them in my database. After reading the documentation, I tried to do something.

I have on my index.html.twig the line :

<td><a href="{{ path('paquet_file', { 'id': uneInfo.id}) }}"</a>{{ uneInfo.urlPaquet }} </td>

On my controller :

namespace Site\PagesBundle\Controller;

use Site\PagesBundle\Entity\Paquet;
use Site\PagesBundle\Entity\TypeUser;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Vich\UploaderBundle\Handler\DownloadHandler;

//........


     /** 
     * Serves an uploaded file.
     *
     * @Route("/{id}/file", name="paquet_file")
     */
    public function fileAction(Paquet $paquet)
    {   
        $downloadHandler = $this->get('vich_uploader.download_handler');

        return $downloadHandler->downloadObject($paquet, $fileField = 'paquetFile', Paquet::class, true);
    }

My entity :

<?php

namespace Site\PagesBundle\Entity;

use DateTimeImmutable;
use Doctrine\ORM\Mapping as ORM;
use Site\PagesBundle\Entity\Paquet;
use Site\PagesBundle\Entity\TypeUser;
use Symfony\Component\HttpFoundation\File\File;

}

But when I click on the URL file :

Screen - My page

I have this file :

Screen - Downloaded file

    I don't use this bundle yet (I plan to work with it soon though). But from what I see in the doc page : https://github.com/dustin10/VichUploaderBundle/blob/master/Resources/doc/downloads/serving_files_with_a_controller.md the 4th argument is the filename while you set true to it.

    So maybe it's just a filename issue ? You could try to set filename to null (I guess it will take the real filename by default) or set your own filename (with extension) as the 4th argument in the downloadObject() call.
