CheckOrigin doesn't work , how to set cors

[cagev]

//here is my options
opts := sockjs.DefaultOptions
opts.ResponseLimit = 4096
opts.RawWebsocket = true
opts.CheckOrigin = func(r *http.Request) bool {
fmt.Printf("check origin request %v\n", r.URL)

	return true
}
opts.Origin = "*"
opts.WebsocketUpgrader = &websocket.Upgrader{}
opts.WebsocketUpgrader.CheckOrigin = func(r *http.Request) bool { return true }

wsHandler := &WSockHandler{prefix, sockjs.NewHandler(prefix, opts, handler)}

@cagev hello, is this still actual? Setting CORS with sockjs-go works for me, but looking on the example you provided it's not obvious why it's not working to you. Can you provide a full example with steps to reproduce an issue locally?
