服务端调用出错Argument func must be callable.

[hinet]

在laravel中服务端调用出错提示：
Argument func must be callable.

`namespace App\Http\Controllers;
use Hprose\Http\Server;
use Illuminate\Http\Request;

class TestController extends Controller
{
public function index(){
$server = new Server();
$server->addFunction('hello',$this);
$server->start();
}
public function hello(){
return "Hello";
}
}`

因调用的是方法，所以应该使用addMethod来添加方法：

$server->addMethod('hello',$this);
