coap.ServeMux does not support root path ("/") handler #41
Description
Adding a handler with path "/" will result in a "http: invalid pattern " panic:
package main
import (
"log"
"net"
"github.com/dustin/go-coap"
)
func main() {
mux := coap.NewServeMux()
mux.Handle("/", coap.FuncHandler(handler))
log.Fatal(coap.ListenAndServe("udp", ":5683", mux))
}
func handler(l *net.UDPConn, a *net.UDPAddr, m *coap.Message) *coap.Message {
log.Printf("%s-%d: %b", a.String(), m.MessageID, m.Payload)
return nil
}
