Gin内置日志中间件Gin框架内置了日志中间件它们记录HTTP请求的基本信息。1.1. 默认日志中间件gin.Default()默认使用了gin.Logger()中间件。funcDefault(opts...OptionFunc)*Engine{debugPrintWARNINGDefault()engine:New()engine.Use(Logger(),Recovery())// 默认使用了gin.Logger()中间件returnengine.With(opts...)}输出格式类似[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_MODErelease - using code: gin.SetMode(gin.ReleaseMode) [GIN-debug] GET /test/ping -- gin-quickstart/handler.TestHello (5 handlers) [GIN-debug] [WARNING] You trusted all proxies, this is NOT safe. We recommend you to set a value. Please check https://github.com/gin-gonic/gin/blob/master/docs/doc.md#dont-trust-all-proxies for details. [GIN-debug] Environment variable PORT is undefined. Using port :8080 by default [GIN-debug] Listening and serving HTTP on :8080 [GIN] 2025/12/29 - 15:40:59 | 200 | 256.625µs | 127.0.0.1 | GET /test/ping1.2. 禁用debug日志gin框架默认使用Debug模式所以上面的示例中会有很多GIN-debug日志。如果不想打印这些日志可以将gin模式改为生产模式gin.SetMode(gin.ReleaseMode)// 指定为生产模式router:gin.Default()日志示例[GIN]2025/12/29-15:44:41|200|320.666µs|127.0.0.1|GET/test/ping可以看到GIN-debug日志都消失了1.3. 控制日志颜色根据检测到的 TTY控制台的日志输出默认是有颜色的。我们可以使用以下两个方法来控制日志的颜色显示gin.DisableConsoleColor()禁用颜色打印。gin.ForceConsoleColor()强制颜色打印。// 禁用颜色打印gin.DisableConsoleColor()router:gin.Default()// 强制颜色打印gin.ForceConsoleColor()router:gin.Default()1.4. 自定义日志中间件1.4.1. 日志配置项gin框架底层使用gin.LoggerConfig来配置日志中间件。// LoggerConfig 定义日志中间件的配置typeLoggerConfigstruct{// 格式化方法默认为gin.defaultLogFormatterFormatter LogFormatter// 日志输出位置默认为gin.DefaultWriterOutput io.Writer// 不输出日志的URL路径SkipPaths[]string// 自定义方法用于判断哪些日志不需要输出Skip Skipper}默认的gin.Logger()中间件源码如下funcLogger()HandlerFunc{returnLoggerWithConfig(LoggerConfig{})}从源码看到该日志中间件使用的是默认配置格式化方法为gin.defaultLogFormatter。日志输出位置为gin.DefaultWriter。没有不需要输出日志的路由路径。1.4.2. 自定义方法gin框架提供了如下几个方法供我们自定义日志中间件gin.LoggerWithConfig(conf LoggerConfig)最灵活的自定义方法支持直接使用gin.LoggerConfig配置项来灵活自定义日志中间件。gin.LoggerWithFormatter(f LogFormatter)自定义日志格式化方法控制日志输出格式。gin.LoggerWithWriter(out io.Writer, notlogged ...string)自定义日志输出位置以及不需要输出日志的路径。源码// LoggerWithFormatter instance a Logger middleware with the specified log format function.funcLoggerWithFormatter(f LogFormatter)HandlerFunc{returnLoggerWithConfig(LoggerConfig{Formatter:f,})}// LoggerWithWriter instance a Logger middleware with the specified writer buffer.// Example: os.Stdout, a file opened in write mode, a socket...funcLoggerWithWriter(out io.Writer,notlogged...string)HandlerFunc{returnLoggerWithConfig(LoggerConfig{Output:out,SkipPaths:notlogged,})}可以看到另外两个方法底层调用的依旧是gin.LoggerWithConfig(conf LoggerConfig)方法1.4.3. 自定义日志格式示例如果需要自定义日志格式可以使用gin.LoggerWithFormatter()r.Use(gin.LoggerWithFormatter(func(param gin.LogFormatterParams)string{returnfmt.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,)}))1.4.4. 自定义日志输出位置示例通过修改gin.DefaultWriter来设置输出位置// 输出到文件f,_:os.Create(gin.log)gin.DefaultWriterio.MultiWriter(f)r:gin.Default()// 同时输出到控制台和文件f,_:os.Create(gin.log)gin.DefaultWriterio.MultiWriter(f,os.Stdout)r:gin.Default()通过gin.LoggerWithWriter(out io.Writer, notlogged ...string)来设置输出位置// 同时输出到控制台和文件logFile,_:os.OpenFile(./logs/gin.log,os.O_CREATE|os.O_RDWR|os.O_APPEND,0666)router:gin.New()router.Use(gin.LoggerWithWriter(io.MultiWriter(logFile,os.Stdout)))2. 集成第三方日志插件Gin框架内置的日志中间件不直接支持日志级别控制等功能但可以通过集成第三方日志插件实现如logrus、zap等。2.1. 集成 logruspackagemainimport(github.com/gin-gonic/gingithub.com/sirupsen/logrusos)funcmain(){// 设置logrus格式log:logrus.New()log.SetFormatter(logrus.JSONFormatter{})log.SetOutput(os.Stdout)// 设置日志级别log.SetLevel(logrus.InfoLevel)r:gin.New()// 自定义日志中间件r.Use(func(c*gin.Context){start:time.Now()c.Next()latency:time.Since(start)clientIP:c.ClientIP()method:c.Request.Method statusCode:c.Writer.Status()path:c.Request.URL.Pathiflen(c.Errors)0{// 错误日志log.WithFields(logrus.Fields{latency:latency,client_ip:clientIP,method:method,status_code:statusCode,path:path,errors:c.Errors.ByType(gin.ErrorTypePrivate).Strings(),}).Error(Request Error)}else{// 普通请求日志log.WithFields(logrus.Fields{latency:latency,client_ip:clientIP,method:method,status_code:statusCode,path:path,}).Info(Request Info)}})r.GET(/hello,func(c*gin.Context){c.JSON(200,gin.H{message:Hello World})})r.GET(/error,func(c*gin.Context){c.AbortWithError(500,errors.New(internal error))})r.Run()}2.2 集成 zapZap是Uber开源的高性能日志库适合对性能要求较高的场景packagemainimport(github.com/gin-gonic/gingo.uber.org/zap)funcmain(){logger,_:zap.NewProduction()deferlogger.Sync()// 确保缓冲区日志被刷新r:gin.New()// 自定义zap日志中间件r.Use(func(c*gin.Context){start:time.Now()path:c.Request.URL.Path raw:c.Request.URL.RawQuery c.Next()latency:time.Since(start)clientIP:c.ClientIP()method:c.Request.Method statusCode:c.Writer.Status()ifraw!{pathpath?raw}fields:[]zap.Field{zap.Int(status,statusCode),zap.String(method,method),zap.String(path,path),zap.String(ip,clientIP),zap.Duration(latency,latency),zap.String(user-agent,c.Request.UserAgent()),}iflen(c.Errors)0{fieldsappend(fields,zap.String(error,c.Errors.ByType(gin.ErrorTypePrivate).String()))logger.Error(Request Error,fields...)}else{logger.Info(Request Info,fields...)}})r.GET(/hello,func(c*gin.Context){c.JSON(200,gin.H{message:Hello World})})r.Run()}
