Use golang http handler in AWS Lambda
usage
func helloHandler(w http.ResponseWriter, r *http.Request) {
w.Header().Add("x-powered-by", "delta")
fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))
}
func main() {
mux := http.NewServeMux()
mux.HandleFunc("/hello/", helloHandler)
// start lambda handling if it runs on lambda
// otherwise start http server on port 3000
delta.ServeOrStartLambda(":3000", mux)
}
