Class App \ MySSOServer不存在

Question

我是laravel的先发球员。我正在创造一个sinup形式。我只是从我的教练给出的链接中复制了一个程序。任何人请帮助我。我坚持自己的任务。

错误：Class App \ MySSOServer不存在

编码如下：

 <?php
    namespace App\Http\Controllers;
    use App\MySSOServer;
    class MyServerController extends Controller
    {
        public function index(MySSOServer $ssoServer){
           $command = isset($_REQUEST['command']) ? $_REQUEST['command'] : null;
           if (!$command || !method_exists($ssoServer, $command)) {
               header("HTTP/1.1 404 Not Found");
               header('Content-type: application/json; charset=UTF-8');
               echo json_encode(['error' => 'Unknown command']);
               exit();
           }
           $user = $ssoServer->$command();
           if($user)
              return response()->json($user);
          }
    }
?>
