// 选中第一个Sheet, 这样第一行当做属性名
Excel::selectSheetsByIndex(0)->load($cretae_path, function ($reader) use (&$errorRow, &$successCount, &$rowsCount, &$user_id, &$item, &$file_url, &$history, $entry_way_id) {

安装使用
Require this package in your composer.json and update composer. This will download the package and PHPExcel of PHPOffice.
"maatwebsite/excel": "~2.1.0"
After updating composer, add the ServiceProvider to the providers array in config/app.php
Maatwebsite\Excel\ExcelServiceProvider::class,
You can use the facade for shorter code. Add this to your aliases:
'Excel' => Maatwebsite\Excel\Facades\Excel::class,
The class is bound to the ioC as excel
$excel = App::make('excel');
To publish the config settings in Laravel 5 use:
php artisan vendor:publish --provider="Maatwebsite\Excel\ExcelServiceProvider"
This will add an excel.php config file to your config folder.
