logger

Gin middleware/handler to logger url path using rs/zerolog.

Example

package main

import (
	"fmt"
	"os"
	"regexp"
	"time"

	"github.com/printesoi/logger"
	"github.com/gin-gonic/gin"
	"github.com/rs/zerolog"
	"github.com/rs/zerolog/log"
)

var (
	rxURL = regexp.MustCompile(`^/regexp\d*`)
)

func main() {
	zerolog.SetGlobalLevel(zerolog.InfoLevel)
	if gin.IsDebugging() {
		zerolog.SetGlobalLevel(zerolog.DebugLevel)
	}

	log.Logger = log.Output(
		zerolog.ConsoleWriter{
			Out:     os.Stderr,
			NoColor: false,
		},
	)

	r := gin.New()

	// Add a logger middleware, which:
	//   - Logs all requests, like a combined access and error log.
	//   - Logs to stdout.
	r.Use(logger.SetLogger())

	// Custom logger
	subLog := zerolog.New(os.Stdout).With().
		Str("foo", "bar").
		Logger()

	r.Use(logger.SetLogger(logger.Config{
		Logger:         &subLog,
		UTC:            true,
		SkipPath:       []string{"/skip"},
		SkipPathRegexp: rxURL,
	}))

	// Example ping request.
	r.GET("/ping", func(c *gin.Context) {
		c.String(, "pong "+fmt.Sprint(time.Now().Unix()))
	})

	// Example skip path request.
	r.GET("/skip", func(c *gin.Context) {
		c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
	})

	// Example skip path request.
	r.GET("/regexp1", func(c *gin.Context) {
		c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
	})

	// Example skip path request.
	r.GET("/regexp2", func(c *gin.Context) {
		c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
	})

	// Listen and Server in 0.0.0.0:8080
	r.Run(":8080")
}
