在Lumen 7中验证时，如何返回自定义JSON数组名称和内部元素？

use Illuminate\Http\Response;

public function customResponse($data, $arrayName)
{
    $responseData = [
        $arrayName => $data,
    ];

    return response()->json($responseData);
}

public function getUsers()
{
    $users = User::all();

    return $this->customResponse($users, 'users');
}
