<?php

namespace app\controller;
use support\Request;

class FilesController extends AuthController
{
    public function download_file(Request $request)
    {
        $directory = public_path() . 'tmp_download/';
        $localFile = $directory . '5.jpg';
        return response()->download($localFile, '5.jpg');
    }
