x/net/websocket: No way to manage connection outside of handler #5959
Description
Currently there is no way to get a websocket.Conn object without leaving the handler, or
without having a handler at all. I need to wrap the websocket.Conn object for another
library, but not without maintaing a blocked go routine.
I suggest adding this method:
func (s Server) Upgrade(w http.ResponseWriter, req *http.Request) (conn *Conn, err
error) {
var rwc net.Conn
var buf *bufio.ReadWriter
if rwc, buf, err = w.(http.Hijacker).Hijack(); err != nil {
return nil, err
}
conn, err = newServerConn(rwc, buf, req, &s.Config, s.Handshake);
return
}
