Here is my code ( In my code I will uploading the file and after that when I click on a button then Its give me a download link with some expire time.

Code : (uploading )

public function upload_file(Request $request){
        $rules = array(
            'title' => 'required',
            'tags' => 'required',
            'cover' => 'required',
            'category' => 'required',
            'file_to_be_upload' => 'required',
            'datepicker' => 'required'
        );
        $messages = [
            'doc_file.required' => 'The Upload File field is required',
            'datepicker.required' => 'The Select Date field is required'
        ];
        $validator = Validator::make($request->all(),$rules, $messages);
        if ($validator->fails()) {
            return redirect()->back()->withErrors($validator)->withInput();
        }else {

            $title = $request->input('title');
            $tags = $request->input('tags');
            $file_to_be_upload = $request->file('file_to_be_upload');

            $type = $request->input('type');
            $fileName = $file_to_be_upload->getClientOriginalName();
            $extension = $file_to_be_upload->getClientOriginalExtension();
//            // Date String
            $expl = explode('-', $request->input('datepicker'));
            $current_date = $expl[0];
            $current_month = $expl[1];
            $current_year = $expl[2];

            $product_id = strtoupper($current_month) . 'DF' . $current_year . 'DF' . time();
            $cover_url = $this->add_cover($request->file('cover'), $product_id);
            // Storing Process
            $student   = app('firebase.firestore')->database()->collection($type)->document($fileName);
            $firebase_storage_path = $type . '/' . $current_year . '/' . $current_month . '/' . $current_date . '/';

            $name = $student->id();
            $localfolder = public_path('firebase-temp-uploads') .'/';
            $file = $name. '.' . $extension;
            if ($file_to_be_upload->move($localfolder, $file)) {
                $uploadedfile = fopen($localfolder.$file, 'r');
                app('firebase.storage')->getBucket()->upload($uploadedfile, ['name' => $firebase_storage_path . $name]);
                // will remove from local laravel folder
                unlink($localfolder . $file);
                // Storing All Details into Database


                $result = Product::create([
                    'product_id' => $product_id,
                    'title' => $request->input('title'),
                    'slug' => $request->input('title'),
                    'description' => $request->input('description'),
                    'tags' => $request->input('tags'),
                    'type' => $request->input('type'),
                    'category' => $request->input('category'),
                    'doc_file' => $fileName,
                    'cover_image' => $cover_url,
                    'file_location' => $firebase_storage_path,
                    'status' => '0',
                    'added_by' => Cookie::get('admin_id'),
                    'uploaded_at' => $request->input('datepicker'),
                ])->categories()->sync($request->input('category'));

                if($result){
                    return redirect()->back()->with( [ 'status' => "Document Uploaded Successfully" ] );
                }else{
                    return redirect()->back()->with( [ 'status' => "Something went wrong" ] );
                }
            } else {
                return 'error';
            }
        }
    }

Code : (Getting Downlaod link)

$document = Product::where("product_id", $product_id)->first();
        $file_location = $document->file_location;
        $fileName = $document->doc_file;
        $type = $document->type;
        $expiresAt = new \DateTime('3600');
        $imageReference = app('firebase.storage')->getBucket()->object($file_location . $fileName);
        if($imageReference->exists()){
            $image = $imageReference->signedUrl($expiresAt);
            return redirect()->back()->with( [ 'link' => $image , 'product_id' => $product_id] );
        }else{
            return redirect()->back()->with( [ 'status' => "Something went wrong" ] );
        }

I just wanted to do the same thing but In 1 time.

in above method I am requesting 2-3 times to get a single file.

Is there any way to upload the file and get the download URL (without expire at) and then I will save that url into database
