Laravel 5.4存储: downloading files.文件不存在，但显然它存在

Question

我一直在纠结这个问题。我上传的内容如下:

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 收到 FileNotFound 异常但是，如果我用这个代替:

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

我明白了

FileNotFoundException in File.php line 37: The file "use calib;

insert into notes(tool_id,user_id,note,created_at,updated_at) VALUES(1,1,'windows server 2008 sucks',now(),now());" does not exist

这是文件的实际内容...

显然可以找到该文件。但为什么不下载呢？

试试这个:

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