Hello, I'm trying to use this package for different namespaces
Here's the working version using github.com/googollee/go-socket.io
func main() {
server := socketio.NewServer(&engineio.Options{
Transports: []transport.Transport{
&polling.Transport{
CheckOrigin: allowOriginFunc,
},
&websocket.Transport{
CheckOrigin: allowOriginFunc,
},
},
})
server.OnConnect("/", func(s socketio.Conn) error {
s.SetContext("")
log.Println("connected:", s.ID())
return nil
})
server.OnEvent("/", "notice", func(s socketio.Conn, msg string) {
log.Println("notice:", msg)
s.Emit("reply", "have "+msg)
})
server.OnEvent("/chat", "msg", func(s socketio.Conn, msg string) string {
log.Println("chat:", msg)
s.SetContext(msg)
return "recv " + msg
})
server.OnEvent("/", "bye", func(s socketio.Conn) string {
last := s.Context().(string)
s.Emit("bye", last)
s.Close()
return last
})
server.OnError("/", func(s socketio.Conn, e error) {
log.Println("meet error:", e)
})
server.OnDisconnect("/", func(s socketio.Conn, reason string) {
log.Println("closed", reason)
})
go func() {
if err := server.Serve(); err != nil {
log.Fatalf("socketio listen error: %s\n", err)
}
}()
defer server.Close()
http.Handle("/socket.io/", server)
http.Handle("/", http.FileServer(http.Dir("asset")))
log.Println("Serving at http://localhost:8001...")
log.Fatal(http.ListenAndServe(":8001", nil))
}When I try to use this package I'm getting error. Not sure what might be the issue
