go get -u github.com/syhlion/httplog

Example

package main

import (
  "fmt"
  "net/http"

  "github.com/urfave/negroni"
)

func main() {
  mux := http.NewServeMux()
  mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
    fmt.Fprintf(w, "Welcome to the home page!")
  })

  n := negroni.New()
  n.Use(httplog.NewLogger())
  n.UseHandler(mux)

  http.ListenAndServe(":3004", n)
}

Will print a log similar to:

[http log] 127.0.0.1:46945 - [2015-12-30 09:05:27.502464588 +0800 CST] "POST /register" 200 37.96608ms  "username=syhlion&email=xxx@gmail.com"
