Connecting Unity3d with Node.js - node.js

Question

I am trying to use socket.io to connect my unity3d program with node.js server.
Using the UnitySocketIO, I succeeded the connection between the client and server.
However, On or Emit method does not work.
Can someone help me with this problem?
void Start () {
string socketUrl = "http://127.0.0.1:50122";
Debug.Log("socket url: " + socketUrl);
this.socket = new Client(socketUrl);
this.socket.Opened += this.SocketOpened;
this.socket.Message += this.SocketMessage;
this.socket.SocketConnectionClosed += this.SocketConnectionClosed;
this.socket.Error += this.SocketError;
this.socket.Connect();
}
private void SocketOpened (object sender, EventArgs e) {
Debug.Log("socket opened"); // i got this message
this.socket.On ("message", (data) => {
Debug.Log ("message : " + data);
});
this.socket.Emit("join", "abc");
Debug.Log("Emit done"); // i got this message
}
....
io.sockets.on('connection', function (socket) {
console.log('connect'); // i got this message
socket.emit('message', 'Hello World!');
socket.on('join', function (id) {
console.log('client joined with id ' + id);
socket.emit('message', 'Hello ' + id);
});
});

Your event probably attached in wrong order, try like this:
void Start() {
string socketUrl = "http://127.0.0.1:50122";
Debug.Log("socket url: " + socketUrl);
this.socket = new Client(socketUrl);
this.socket.Opened += this.SocketOpened;
this.socket.Message += this.SocketMessage;
this.socket.SocketConnectionClosed += this.SocketConnectionClosed;
this.socket.Error += this.SocketError;
this.socket.On("message", (data) => {
Debug.Log("message: " + data);
});
this.socket.Connect();
}
And for node:
io.sockets.on('connection', function(socket) {
console.log('client connected');
socket.emit('message', 'Hello World!');
});
As well do not allow client to decide own ID, as it is "hackable" in most cases. Only server should make important decisions and not client.
