gin自定义日志格式

func main() {
	router := gin.New()

	// LoggerWithFormatter 中间件会将日志写入 gin.DefaultWriter
	// By default gin.DefaultWriter = os.Stdout
	router.Use(gin.LoggerWithFormatter(func(param gin.LogFormatterParams) string {

		// 你的自定义格式
		return fmt.Sprintf("%s - [%s] \"%s %s %s %d %s \"%s\" %s\"\n",
				param.ClientIP,
				param.TimeStamp.Format(time.RFC1123),
				param.Method,
				param.Path,
				param.Request.Proto,
				param.StatusCode,
				param.Latency,
				param.Request.UserAgent(),
				param.ErrorMessage,
		)
	}))
	router.Use(gin.Recovery())

	router.GET("/ping", func(c *gin.Context) {
		c.String(200, "pong")
	})

	router.Run(":8080")
}
