如何使用没有标准auth的laravel RegisterController（php artisan make：Auth）

Question

I thought that if($this->validator($request->all())) this would return true or false, but it returns a object every time returns true

use RegistersUsers;

protected $redirectTo = '/home';

    public function __construct()
    {
        $this->middleware('guest');
    }


    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'surname' => 'required|string|max:255',
            'age' => 'required|integer|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
        ]);
    }


    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'surname' => $data['surname'],
            'age' => $data['age'],
            'email' => $data['email'],
            'password' => bcrypt($data['password']),
        ]);
    }

    public function register(Request $request){

        if($this->validator($request->all())){
            //create user
            // function after registration
            var_dump('success');
        }else{
            //redirect to ...
            var_dump('fail');
        }
    }
