Laravel, getting uploaded file's url

问题

I'm currently working on a Laravel 5.5 project, where I want to upload files, and then, I want to get their url back of the file (I have to use it client side).

now my code looks like this:

public function pdfUploader(Request $request)
{
  Log::debug('pdfUploader is called. ' . $request);
  if ($request->hasFile('file') && $request->file('file')->isValid()) {
    $extension = $request->file->extension();
    $fileName = 'tmp' . round(microtime(true) * 1000) . '.' . $extension;
    $path = $request->file->storeAs('temp', $fileName);
    return ['status' => 'OK', 'path' => URL::asset($path)];
  }
  return ['status' => 'NOT_SAVED'];
}

It works fine, I got back the OK status, and the path, but when I want to use the path, I got HTTP 404. I checked, the file is uploaded fine..

My thought is, I should register the new url in the routes. If I have to, how can I do it dynamically, and if its not necessary what is wrong with my function?

Thx the answers in advance.

By default laravel store all uploaded files into storage directory, for example if you call $request->file->storeAs('temp', 'file.txt'); laravel will create temp folder in storage/app/ and put your file there:

$request->file->storeAs('temp', 'file.txt'); => storage/app/temp/file.txt
$request->file->storeAs('public', 'file.txt'); => storage/app/public/file.txt

However, if you want to make your uploaded files accessible from the web, there are 2 ways to do that:

Move your uploaded file into the public directory

$request->file->move(public_path('temp'), $fileName); // => public/temp/file.txt
URL::asset('temp/'.$fileName); // http://example.com/temp/file.txt

NOTE: make sure that your web server has permissions to write to the public directory

Create a symbolic link from storage directory to public directory

php artisan storage:link

This command will create a symbolic link from public/storage to storage/app/public, in this case we can store our files into storage/app/public and make them accessible from the web via symlinks:

$request->file->storeAs('public', $fileName); // => storage/app/public/file.txt
URL::asset('storage/'.$fileName); // => http://example.com/stoage/file.txt
