Laravel 7中未找到文件异常

问题描述

我正在开发一个laravel应用程序，我想通过单击一个按钮来下载文件.我已将文件存储在/storage/app/public/1.pdf 中，并创建了指向 public 文件夹的符号链接.现在，我尝试了多种下载文件的方法，但是每次，我都会收到错误路径上的文件未找到异常.

I am working on a laravel application where I want to download a file by clicking a button. I have stored the file in /storage/app/public/1.pdf and have created a symbolic link to the public folder. Now I tried many ways to download the file but every time, I receive error File Not Fount Exception at path.

我尝试了以下下载文件的方法:

I have tried the following ways for downloading the file:

1 -
$name = "file.pdf";
$file = storage_path(). "/app/public/1.pdf";
$headers = array(
'Content-Type: application/pdf');
return Storage::download($file, $name, $headers);

2 -
$name = "file.pdf";
    $file = public_path(). "/storage/1.pdf";
    $headers = array(
          'Content-Type: application/pdf',
        );

    return Storage::download($file, $name, $headers);


3 -
$name = "file.pdf";
    $file = Storage::url("1.pdf");
    $headers = array(
          'Content-Type: application/pdf',
        );

    return Storage::download($file, $name, $headers);

这是我收到的错误消息:

因此，如果文件存储在 storage/app/public/1.pdf 中，请不要将这样的绝对路径传递到Storage Facade:

So, if the file is stored in storage/app/public/1.pdf, do not pass to the Storage facade an absolute path like this one:

$file = storage_path(). "/app/public/1.pdf";
return Storage::download($file);

请使用相对于文件系统配置文件中定义的 root 目录的路径:

Instead use a path relative to the root directory defined in your filesystems configuration file:

$file = "public/1.pdf";
$name = "file.pdf";
return Storage::download($file, $name);
