I'm trying to figure out the best way to handle requests to /
and only /
in Go and handle different methods in different ways. Here's the best I've come up with:
package main
import (
"fmt"
"html"
"log"
"net/http"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if r.URL.Path != "/" {
http.NotFound(w, r)
return
}
if r.Method == "GET" {
fmt.Fprintf(w, "GET, %q", html.EscapeString(r.URL.Path))
} else if r.Method == "POST" {
fmt.Fprintf(w, "POST, %q", html.EscapeString(r.URL.Path))
} else {
http.Error(w, "Invalid request method.", 405)
}
})
log.Fatal(http.ListenAndServe(":8080", nil))
}
Is this idiomatic Go? Is this the best I can do with the standard http lib? I'd much rather do something like http.HandleGet("/", handler)
as in express or Sinatra. Is there a good framework for writing simple REST services? web.go looks attractive but appears stagnant.
Thank you for your advice.
