Laravel上传生成的PDF到存储

Question

I have a Laravel JSON API project where I upload a PDF file to storage. I get the form data from the front end.

Storage::cloud()->put($randompath . $request->file('given_pdf')
        ->getClientOriginalName(), file_get_contents($request->file('given_pdf')));

However, now I am using barryvdh/laravel-dompdf package and I have to do something like that:

$pdf = PDF::loadView('documents.client_road_order_doc', ['data' => $data]);
$file = $pdf->download('client_order_doc.pdf')->getOriginalContent();
Storage::cloud()->put($randompath . "filename", $file);

I have to write different functions for this one, because $file isn't same type as $request->file('given_pdf'); I don't want to write a different function. My question is can I get from $pdf->download('client_order_doc.pdf') the same type of object like $request->file('given_pdf')?
