I am trying to create websockets using golang with gorilla on aws (without docker) with load balancer, I have a certificate connected to the load balancer.
I managed to make the code work with http, but when I try to use the code over https it does not work.
What am I doing wrong? When moving from http to https I changed the client request to wss instead of ws, and added the certificate to the load balancer. Here is my code. This is my main.go
http.HandleFunc("/wss", serveWs)
fmt.Printf("Listening on port %s
", port)
if err := http.ListenAndServe(":"+port, nil); err != nil {
fmt.Printf(err.Error())
}
This is the serveWs:
func serveWs(w http.ResponseWriter, r *http.Request) {
upgrader.CheckOrigin = func(r *http.Request) bool {
// allow all connections by default
return true
}
ws, err := upgrader.Upgrade(w, r, nil)
if err != nil {
fmt.Println(err)
if _, ok := err.(websocket.HandshakeError); !ok {
log.Println(err)
}
return
}
var lastMod time.Time
if n, err := strconv.ParseInt(r.FormValue("lastMod"), 16, 64); err != nil {
lastMod = time.Unix(0, n)
}
go writer(ws, lastMod, w, r)
reader(ws)
}
This is the request:
var conn = new WebSocket("wss://https://www.weldpad.com/wss?"
When I send a request from the client i get the folloing error:
failed: Error during WebSocket handshake: Unexpected response code: 400
Looking at the server log, I see.
"could not find upgrade header with token 'websocket"
This is my load balancer configuration:
