What did you do?

go.mod

module github.com/cuiweixie/websocket_test

go 1.21

require github.com/gorilla/websocket v1.5.3 // indirect

wss.go

package main

import (
    "log"
    "net/http"

    "github.com/gorilla/websocket"
)

func main() {
    webURL := "wss://wspap.okx.com:8443/ws/v5/public"

    header := http.Header{}
    var dialer websocket.Dialer
    _, _, err := dialer.Dial(webURL, header)
    if err != nil {
        log.Fatalf("dial failed: %v", err)
    }
    log.Println("connection ok")
}

go run wss.go

What did you see happen?

2024/07/19 19:01:13 dial failed: websocket: bad handshake
exit status 1

What did you expect to see?

if change go mod to:

module github.com/cuiweixie/websocket_test

go 1.22

require github.com/gorilla/websocket v1.5.3 // indirect

will result in:

2024/07/19 19:01:39 connection ok

It's strange that using go1.21 doesn't work, but go1.22 or later does.

I think this is controlled by the GODEBUG setting tlsrsakex where the default changed from enabled in go1.21 to disabled in go1.22. I don't think there's anything to do here as the new behavior is more correct and we aren't going to change the default GODEBUG for a previous version.

main » GODEBUG=tlsrsakex=1 go1.22.5 run .
2024/07/19 12:18:46 dial failed: websocket: bad handshake
exit status 1

main » GODEBUG=tlsrsakex=0 go1.22.5 run . 
2024/07/19 12:18:56 connection ok
