如何使用 symfony5 通过 url 发送上传的文档

Question

我正在尝试通过 symfony 发送上传到 maarch 签名的文档。 我已经用纯 php 编写了我的代码，我想在 symfony 上调整它们，但我不知道该怎么做。 下面是用php编写的代码。

表单.php

<?php
    $url = "http://ggrand:maarch@169.176.61.102:5600/rest/users";
    $response = file_get_contents($url);
?>

<!DOCTYPE html>
<html>
    <head>
        <meta charset="UTF-8" />
        <title>Envoi d'un document dans le parapheur</title>
    </head>

    <script type="text/javascript">
        var jsonObj =<?php echo $response;?>
    </script>

    <body>
        <form action="processJson_tableau.php" method="post" enctype="multipart/form-data">
            <table>
                <tr>
                    <td>Titre du document</td>
                    <td><input type="text" name="title" /></td>
                </tr>
                <tr>
                    <td>Référence du document</td>
                    <td><input type="text" name="reference" /></td>
                </tr>
                <tr>
                    <td>Description du document</td>

        $errors[] = "File exceeds maximum size (4MB)";
      }

      if (empty($errors)) {

这是我开始在 symfony 上写的控制器代码，但现在我卡住了，我不知道如何前进。

<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;
use App\Entity\Upload;
use App\Form\UploadType;
use Doctrine\Common\Persistence\ObjectManager;
use Doctrine\ORM\EntityManagerInterface;
use Symfony\Component\HttpFoundation\Request;

class FileController extends AbstractController
{
    /**
     * @Route("/home", name="accueil")
     */

   public function index(Request $request, EntityManagerInterface $manager)
    {
        $upload = new Upload();

        $form = $this->createForm(UploadType::class, $upload);

        $form->handleRequest($request);

        if($form->isSubmitted() && $form->isValid()) {
            $manager->persist($upload);
            $manager->flush();

            //$enc = $upload->getDocument();
            //$file = base64_encode($enc);
            $file = $upload->getDocument();
            $fileName = md5(uniqid()).'.'.$file->guessExtension();
            $file->move($this->getParameter('upload_directory'), $fileName);
            $enc = base64_encode($file);
            $upload->setDocument($fileName);

            return $this->redirectToRoute('accueil');

        }

        return $this->render('file/index.html.twig', array(
            'form' => $form->createView(),
        ));
    }
}

是否有必要使用 symfony 显示我显示表单的部分？

要上传和下载文件，您可以使用Vich 上传程序包，它允许您：

自动命名文件并将其保存到配置的目录

当文件从
数据存储作为 Symfony\\Component\\HttpFoundation\\File\\File 的一个实例

从数据存储中删除实体或文档后，从文件系统中删除文件

模板助手以生成文件的公共 URL

完整文档在这里： Vich 上传器文档。

因此，要将这个包添加到您自己的代码中，您应该添加一个实体来存储文件属性和文件本身的引用。 该包提供了一个对象，可帮助您将文件存储在您想要的位置。
