Symfony上传PDF文件后无法打开或删除的权限问题求助

在Symfony 6.4.3应用中上传PDF文件时，通过UploadedFile可成功将PDF存储到指定目录public/pdf/，但无管理员权限的用户无法打开或删除这些PDF文件。应用中其他上传.json或.txt文件的目录不存在此问题。

控制器代码（src/Controller/AwsExtractController.php） #

<?php

//src/Controller/AwsExtractController.php

namespace App\Controller;

use App\Entity\AwsPdfDocument;
use App\Form\AwsPdfDocumentFormType;

use App\Service\FileUploader;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
use Doctrine\ORM\EntityManagerInterface;

class AwsExtractController extends AbstractController
{
    public function __construct()
    {}

    /**
     * @Route("/documents/scan", name="scan_documents")

     */
    public function index(Request $request, EntityManagerInterface $entityManager, FileUploader $fileUploader)
    {
        $form = $this->createForm(AwsPdfDocumentFormType::class);
        $form->handleRequest($request);

        $analysedPdfs = $entityManager->getRepository(AwsPdfDocument::class)->findAll();

        if ($form->isSubmitted() && $form->isValid()) 
        {
            $files = $form->get('files')->getData();

            if ($files) 
            {
                foreach ($files as $file) 
                {
                    //PROBLEM
                    $fileName = $fileUploader->upload($file);
                    dd("end");
                }
            }
        }
        return $this->render(
            'aws/aws_scan_document/index.html.twig',
            [
                'form' => $form->createView(),
            ]
        );
    }
}

文件上传服务代码（src/Service/FileUploader.php） #

<?php

// src/Service/FileUploader.php

namespace App\Service;

use Symfony\Component\HttpFoundation\File\Exception\FileException;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\String\Slugger\SluggerInterface;

class FileUploader
{
    public function __construct(
        private string $targetDirectory,
        private SluggerInterface $slugger,
    ) {
    }

    public function upload(UploadedFile $file): string
    {
        $originalFilename = pathinfo($file->getClientOriginalName(), PATHINFO_FILENAME);
        $safeFilename = $this->slugger->slug($originalFilename);
        $fileName = $safeFilename . '-' . uniqid() . '.' . $file->guessExtension();
        try 
        {
            $file->move($this->getTargetDirectory(), $fileName);
        } catch (FileException $e) {
            // ... handle exception if something happens during file upload
        }

        return $fileName;
    }

    public function getTargetDirectory(): string
    {
        return $this->targetDirectory;
    }
}

问题现象描述 #

• 打开PDF时：提示无权限访问该文件
• 删除PDF时：提示需要管理员权限才能执行此操作
• 将PDF复制到“我的文档”后：可正常删除该文件

运行环境 #

• PHP 8.1.27
• Composer 2.6.4
• Symfony web server
• Windows 10 Professional

已尝试的解决方法 #

• 更改PDF保存目录，无效
• 手动修改目录和文件权限，无效
• 改用纯PHP代码上传，无效
• 在Windows 10虚拟机部署应用后可正常运行，原因不明
