前一段需要项目中需要通过 Excel 导入用户，之前用过 phpexcel，总感觉太过繁琐，印象中 phpexcel 也很久没更新，看到项目中有使用 MaatwebsiteExcel，便尝试使用一下。
安装
composer require maatwebsite/excel导入
生成导入类
php artisan make:import AdminsImport --model=Admin会看到 app 下面生成了 Imports 文件夹。
完善业务逻辑
<?php namespace AppImports; use AppModelsAdmin; use function EasyWeChatKernelSupportstr_random; use MaatwebsiteExcelConcernsToModel; class AdminsImport implements ToModel { /** * @param array $row * * @return IlluminateDatabaseEloquentModel|null */ public function model(array $row) { //过滤表头和空行，我这边表头的第一个单元格是id，具体自行调整 if (empty($row[0]) || $row[0] == 'id') { return null; } return new Admin([ 'username' => $row[2], 'password' => bcrypt($row[3]), 'api_token' => str_random(60), ]); } }导入任务
<?php namespace AppConsoleCommands; use AppImportsAdminsImport; use IlluminateConsoleCommand; use MaatwebsiteExcelFacadesExcel; class ImportAdmin extends Command { /** * The name and signature of the console command. * * @var string */ protected $signature = 'importAdmin'; /** * The console command description. * * @var string */ protected $description = '导入admin'; /** * Create a new command instance. * * @return void */ public function __construct() { parent::__construct(); } /** * Execute the console command. * * @return mixed */ public function handle() { Excel::import(new AdminsImport(), storage_path('files/export.xlsx')); $this->info($this->description.'完成'); } }其他逻辑
当然，可能业务必不仅仅是写入数据，可能有一些设计具体业务的操作，那么你可以这样操作。
<?php namespace AppImports; use AppModelsAdmin; use function EasyWeChatKernelSupportstr_random; use MaatwebsiteExcelConcernsToCollection; use IlluminateSupportCollection; class AdminsImport implements ToCollection { public function collection(Collection $rows) { //如果需要去除表头 unset($rows[0]); //$rows 是数组格式 return $this->createData($rows); } public function createData($rows) { $success = 0; foreach ($rows as $row) { $row[0] = (int) $row[0]; if (empty($row[0])) { continue; } (new Admin())->create( [ 'username' => $row[2], 'name' => $row[2], 'password' => bcrypt($row[3]), 'api_token' => str_random(60), ] ); // 其他业务代码 $success++; } return $success.'-'.count($rows); } }执行
php7.2 artisan importAdmin总的来说，使用起来还是简单明了的。

具体导入实现可以搜索 MaatwebsiteExcelExcel 查看，里面还有导出、以队列方式导入等，支持的格式也是多种多样，具体代码如下，功能还是很强大的，足够应付日常需求了。
