1. 写日志文件
func main() { // 禁用控制台颜色 gin.DisableConsoleColor() // 创建记录日志的文件 // os包提供了操作系统函数的不依赖平台的接口 f, _ := os.Create("gin.log") // io包 读,写 gin.DefaultWriter = io.MultiWriter(f) // 如果需要将日志同时写入文件和控制台,请使用以下代码 // gin.DefaultWriter = io.MultiWriter(f, os.Stdout) router := gin.Default() router.GET("/ping", func(c *gin.Context) { c.String(200, "pong") }) router.Run(":8080") }
[GIN-debug] [WARNING] Creating an Engine instance with the Logger and Recovery middleware already attached.
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
- using env: export GIN_MODE=release
- using code: gin.SetMode(gin.ReleaseMode)
[GIN-debug] GET /ping --> main.main.func1 (3 handlers)
[GIN-debug] Listening and serving HTTP on :8080
[GIN] 2020/06/16 - 17:19:21 | 404 | 0s | 127.0.0.1 | GET "/user/:123456"
[GIN] 2020/06/16 - 17:19:25 | 200 | 0s | 127.0.0.1 | GET "/ping"
2. 自定义日志
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" ", 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") }
