Custom log file

For example:

  1. func main() {
  2.     router := gin.New()
  3.     // LoggerWithFormatter middleware will write the logs to gin.DefaultWriter
  4.     // By default gin.DefaultWriter = os.Stdout
  5.     router.Use(gin.LoggerWithFormatter(func(param gin.LogFormatterParams) string {
  6.         // your custom format
  7.         return fmt.Sprintf("%s - [%s] \"%s %s %s %d %s \"%s\" %s\"\n",
  8.                 param.ClientIP,
  9.                 param.TimeStamp.Format(time.RFC1123),
  10.                 param.Method,
  11.                 param.Path,
  12.                 param.Request.Proto,
  13.                 param.StatusCode,
  14.                 param.Latency,
  15.                 param.Request.UserAgent(),
  16.                 param.ErrorMessage,
  17.         )
  18.     }))
  19.     router.Use(gin.Recovery())
  20.     router.GET("/ping", func(c *gin.Context) {
  21.         c.String(200, "pong")
  22.     })
  23.     router.Run(":8080")
  24. }
