ThinkPHP框架如何开发RPC接口

namespace Home\Controller;
use Think\Controller\RpcController;

class ServerController extends RpcController{
    protect $allowMethodList = array('test1','test2'); //表示只允许访问这两个方法
    public function test1(){
         return 'test1';
    }
    public function test2(){
         return 'test2';
    }
 
    private function test3(){
        return 'test3';
   }
 
   protected function test4(){
      return 'test3';
   }
}

namespace Home\Controller;
 
use Think\Controller;
 
class IndexController extends Controller {
 
    public function index(){
 
        Vendor('phpRPC.phprpc_client');
 
        $client = new \PHPRPC_Client('http://serverName/index.php/Home/Server');
 
        // 或者采用
       //$client = new \PHPRPC_Client();
 
       //$client->useService('http://serverName/index.php/Home/Server');
       //调用服务端方法
       $result = $client->test1();
 
    }
 
}
