Laravel 5.4存储:下载文件.文件不存在,但显然它确实存在

Question

我一直在四处走动.我上传了以下工作:

public function store(Tool $tool)
{

     If(Input::hasFile('file')){
        $file = Input::file('file');
        $name = $file->getClientOriginalName();
        $path=Storage::put('public',$file);         //Storage::disk('local')->put($name,$file,'public');

        $file = new File;
        $file->tool_id = $tool->id;
        $file->file_name = $name;
        $file->path_to_file = $path;
        $file->name_on_disk = basename($path);
        $file->user_name = \Auth::user()->name;
        $file->save();

        return back();
    }

但是当我尝试下载时:

public function show($filename)
    {   

        $url = Storage::disk('public')->url($filename);

        ///$file = Storage::disk('public')->get($filename);
        return response()->download($url);
    }

我从laravel获取FileNotFound异常但是,如果我使用它:

$file = Storage::disk('public')->get($filename);
return response()->download($file);

我明白了

File.php第37行中的FileNotFoundException:文件"use calib;

插入笔记(tool_id,user_id,note,created_at,updated_at)VALUES(1,1, 'Windows Server 2008的吮吸',现在(),现在());"不存在

这是文件的实际内容......

它显然可以找到该文件.但为什么不下载？

Answer 1

试试这个:

return response()->download(storage_path("app/public/{$filename}"));

Answer 2

代替：

$file = Storage::disk('public')->get($filename);
return response()->download($file);

和：

return response()->download(storage_path('app/public/' . $filename));

response()->download()获取文件的路径，而不是文件内容。更多信息在这里：https : //laravel.com/docs/5.4/responses#file-downloads
