Cannot get namespaces working in go-socketio

Question

I am using https://github.com/googollee/go-socket.io to create a socket.io server. I am trying to create a namespace, but I cannot connect to the namespace on 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)
    })
}

Customer:

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

Did I miss something?

The namespace functionality in this package seems to be broken. Cm:

Answer 2

You want to prefix your namespaces with a slash. The code you gave as an example would look like this:

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

Give it a try.

:

package main

import (
    "log"
    "net/http"
    "github.com/googollee/go-socket.io"
)


func main() {


    server, err := socketio.NewServer(nil)
    if err != nil {
        log.Fatal(err)
    }
    // server.SetMaxConnection(9000000);

    server.On("connection", func(so socketio.Socket) {
        log.Println("on connection")
        log.Println(so.Id())



        so.On("CHAT", func(msg string) {
            log.Println("CHAT +++++++>"   , msg)
        })


        so.On("server", func(msg string) {
            log.Println("serverpublic  =====>  "   , msg)
        })



        so.On("disconnection", func() {
            log.Println("on disconnect")
        })

    })


    server.On("error", func(so socketio.Socket, err error) {
        log.Println("error:", err)
    })


    http.Handle("/socket.io/", server)
    log.Println("Serving at localhost:16900...")
    log.Fatal(http.ListenAndServe(":15900", nil))
}//main

socket.io (/)

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

.

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

custum.

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 question covers your question around namespaces in socket.io
