无法使名称空间在go-socketio中工作

Question

I'm using https://github.com/googollee/go-socket.io to create a socket.io server. I'm trying to create a namespace, but I'm not able to connect to the namespace from the client side.

Server:

func registerHandlers(server *socketio.Server) {
    server.Of("room1").On("connection", connectionHandler)
}

func connectionHandler(so socketio.Socket) {
    log.Println("on connection")
    so.Join("chat")
    so.On("chat message", func(msg string) {
        so.BroadcastTo("chat", "chat message", msg)
    })
}

Client:

var socket = io.connect("http://localhost:3000/room1");
socket.on('chat message', function(msg){
        $('#messages').append($('<li>').text(msg));
      });

Am I missing something?

On Server side

By default socket.io works in the default namespace (/)

var io = require('socket.io')(http);

You than create namespaces from the default.

var nmspc = io.of('/namespace');

Now you can emit and receive messages within your custum namespace.

nmspc.on('connection', function(socket){
     socket.on('', function(){ 
        ...
     });

}

On the client side you can connect to the namespace with the following

var socket = io('/namespace').connect('http://url:PORT');

I hope this covers your question around namespaces within socket.io
