GoMiddleware : Logger
Middleware that logs a request.
Synopsis
package main
import (
"net/http"
"github.com/gomiddleware/logger"
)
func handler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte(r.URL.Path))
}
func main() {
// create the logger middleware
log := logger.New()
// make the http.Hander and wrap it with the log middleware
handle := http.HandlerFunc(handler)
http.Handle("/", log(handle))
http.ListenAndServe(":8080", nil)
}
When curling this server, you'll see the following in the logs:
2016/10/01 10:05:43.625813 --- GET /about/
2016/10/01 10:05:43.625844 200 GET /about/ 7 34.568µs
2016/10/01 10:05:44.835607 --- GET /
2016/10/01 10:05:44.835636 200 GET / 1 26.633µs
2016/10/01 10:05:50.301461 --- POST /sdf?this=that
2016/10/01 10:05:50.301517 200 POST /sdf?this=that 4 50.09µs
Note the incoming requests (which have --- in their lines) followed by the response (which, in this case all have
200). Then the method, URL, bytes written and time elapsed.

Overview ¶
Package logger provides a logger which can be used as Go Middleware. It logs a line on an incoming request and another line when that request has finished, along with the final status code and the time elapsed.
It also adds a RequestID to the logger which is pulled from the request context, which should be set with the gomiddleware/reqid middleware before this middleware runs.
Incoming fields logged are : method, uri, ip.
Outgoing fields logged are : status, size (bytes), duration.
