<?php
namespace App\Http\Controllers\Module;

use App\Http\Controllers\Controller;
use App\Models\ModuleInterface;
use App\Services\Util\Msg;

class ImportController extends Controller
{
    /**
     * Excel批量导入数据到DB
     * @return \Illuminate\Http\JsonResponse
     */
    public function index() 
    {
        try {
            $file = 'demo.xls';
            Excel::load($file, function($reader) {
                $sourceData = collect($reader->get())->toArray();
                $insertData = [];
                $dateTime = date('Y-m-d H:i:s', time());
                foreach ($sourceData as $key => $item) {
                    $insertData[] = [
                        'Fname'         => $item['fname'],
                        'Fdescribe'     => $item['fdescribe'],
                        'Fservice_id'   => (int)$item['fservice_id'],
                        'Fbusi_person'  => 'tayloryu',
                        'Fdevops'       => 'tayloryu',
                        'Fcreated_at'   => $dateTime,
                        'Fcreator'      => 'tayloryu',
                    ];
                }
                ModuleInterface::insert($insertData);
            });
            
            return Msg::out('导入成功！');
        } catch (Exception $e) {
            return Msg::out($e->getMessage(), $e->getCode());
        }
    }
}
