Simple tool for being a web server and and reporting what's happening. I use this for debugging client apps mostly.

weblog.go

package main

import (
	"flag"
	"log"
	"net/http"
	"time"
)

var addr = flag.String("addr", ":3232", "binding address")

func reporter(ch <-chan string) {
	t := time.Tick(5 * time.Second)
	m := map[string]int{}
	for {
		select {
		case s := <-ch:
			m[s] = m[s] + 1
		case <-t:
			if len(m) > 0 {
				log.Printf("Got some things")
			}
			for k, v := range m {
				log.Printf("   %v: %v", k, v)
			}
			m = map[string]int{}
		}
	}
}

func main() {
	ch := make(chan string)
	go reporter(ch)

	http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
		s := r.Method + ":" + r.URL.Path
		if r.URL.RawQuery != "" {
			s += "?" + r.URL.RawQuery
		}
		ch <- s
		w.WriteHeader(201)
	})
	log.Printf("Listening and serving on %v", *addr)
	log.Fatal(http.ListenAndServe(*addr, nil))
}
