func main() {
    go func() {
        err := http.ListenAndServe(":9998", websocket.Server{websocket.Config{},   
        nil, ChatroomServer})
        if err != nil {
            panic("ListenAndServe: " + err.Error())
        }
    }()
    err := http.ListenAndServe(":9999", nil)
    if err != nil {
        panic("ListenAndServe: " + err.Error())
    }
}

    
func ChatroomServer(ws *websocket.Conn) {
    defer func(){
        ws.Close()
    }()
    var msgReceive string
    var msgToSend string
    for{
        if err := websocket.Message.Receive(ws,&msgReceive);err!=nil{
            fmt.Println("Can't receive")
        }
        if err := websocket.Message.Send(ws,&msgToSend);err!=nil{
            fmt.Println("Can't send")
        }
    }               
}

直接使用http.handler("/", websocket.Handler(ChatroomServer))这种方式会报错.
目前猜测应该是websocket不能和其它的玩意共享一个端口,必须是独立使用一个端口..仅为个人猜测
