phprpc远程调用报错，不知道什么原因

Question

我在学习phprpc远程调用，按照网上的教程，发现报错：Incorrect response id (request id: 1, response id: ) n；好纠结啊，求教。贴出代码如下：
服务端，member.php
<?php
require_once 'jsonRPCServer.php';
/**

• User: Administrator
• Date: 2015/12/28

• Time: 11:06
  */
  class member
  {
  public function getName()
  {

          return 'hello word '; // 返回字符串
  }
  

}
// 服务端调用
$myExample = new member();
// 注入实例
jsonRPCServer::handle($myExample) or print 'no request';

客户端：client.php
<?php
/**

• User: Administrator
• Date: 2015/12/28
• Time: 11:07 */ require_once 'jsonRPCClient.php'; //$url = 'http://localhost/phprpc/server.php'; $url = 'http://localhost/phprpc/member.php'; $myExample = new jsonRPCClient($url); echo '
  '; print_r($myExample); // 客户端调用

try
{
$name = $myExample->getName();
echo $name;
} catch (Exception $e)
{
echo nl2br($e->getMessage()) . '
' . "n";
}
