Go kit: stringsvc1 with http method check

Go kit
stringsvc

When I tested the stringsvc example with different method like GET, it just returned 500. So here it is, the same example with method check.

go build -o server
./server

$ curl -v localhost:8080/uppercase
*   Trying ::1...
* Connected to localhost (::1) port 8080 (#0)
> GET /uppercase HTTP/1.1
> Host: localhost:8080
> User-Agent: curl/7.43.0
> Accept: */*
>
< HTTP/1.1 405 Method Not Allowed

* Connection #0 to host localhost left intact

func methodControl(method string, h http.Handler) http.Handler {
	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
		if r.Method == method {
			h.ServeHTTP(w, r)
		} else {
			http.Error(w, "Method not allowed", http.StatusMethodNotAllowed)
		}
	})
}

http.Handle("/uppercase", methodControl("POST", uppercaseHandler))
