symfony - 无法在 Symfony2 websocket 连接上调用函数

Question

首先我使用 JDare/ClankBundle
我正在按照这些说明从客户端调用函数
https://github.com/JDare/ClankBundle/blob/master/Resources/docs/RPCSetup.md

我一直在控制台上收到此错误“RPC 错误 [对象对象] 未定义”

我注意到如果我拼错了 notify_func 函数也没关系，它仍然会抛出相同的错误。
我不知道我做错了什么，但我认为没有找到该函数的开头？

This is the client side (Twig)

websocket连接成功

  <script type="text/javascript">
        var myClank = Clank.connect('ws://localhost:9999');

        myClank.on("socket/connect", function(session){
            alertify.success("Connected to websocket server");

            //this will call the server side function "Sample::addFunc"
            session.call("notify/notify_func",[2,5])
                .then(  //using "then" promises.

                    function(result) //the function for a valid result
                    {
                        alertify.log("RPC Valid! "+result);
                    },
                    function(error, desc) // the function to handle an error
                    {
                        alertify.log("RPC Error"+" "+error+" "+desc);
                    }

                );
        });

        myClank.on("socket/disconnect", function(error){
            alertify.error("Disconnect for "+error.reason+" with code "+error.code);
        });
    </script>

这是服务器端

    <?php
namespace Gabriel\NotificationsBundle\RPC;
use Ratchet\ConnectionInterface as Conn;

class PostCommentNotificationService
{
    public function notifyFunc(Conn $conn,$params)
    {
        return array("result"=>array_sum($params));
    }
}

这是配置

#services.yml
services:
     notifications.newcommentpost:
       class: Gabriel\NotificationsBundle\RPC\PostCommentNotificationService
#config.yml
     # Clank Configuration
clank:
    web_socket_server:
        port: 9999       #The port the socket server will listen on
        host: localhost   #(optional) The host ip to bind to
    rpc:
       -
        name: "notify" #Important! this is the network namespace used to match calls to this service!
        service: "notifications.newcommentpost" #The service id.

我有一个非常相似的问题。

我发现停止并重新启动内置的 websocket 服务器解决了这个问题。对 websocket 代码所做的每一次修改都需要重新启动 websocket 服务器才能使这些更改发生...

php app/console clank:server
