Status Code Tracker

---

Small utility for getting the status code of a finished http request.

### Usage

```go

package main

import (

	"fmt"

	"net/http"

	"github.com/gorilla/mux"

	status "github.com/rikonor/go-status-code-tracker"

)

func main() {

	r := mux.NewRouter()

	r.HandleFunc("/", mainHandler)

	http.Handle("/", middleware(r))

	http.ListenAndServe(":8080", nil)

}

func middleware(h http.Handler) http.Handler {

	return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {

		// wrap the ResponseWriter with a StatusCodeTracker

		t := status.Track(w)

		h.ServeHTTP(t, r)

		// Can now get the response status code

		fmt.Println(t.Status())

	})

}

func mainHandler(w http.ResponseWriter, r *http.Request) {

	http.Error(w, "error", 400)

}

```
