gin 为什么插入了2次记录

Question

// 日志记录到文件
func LogerMiddleware() gin.HandlerFunc {
   dir := file.GetPwd()
   logFilePath := fmt.Sprintf("%s/%s%s", dir, setting.AppSetting.RuntimeRootPath, setting.AppSetting.LogSavePath)
   logFileName := "gin"

   // 日志文件
   fileName := path.Join(logFilePath, logFileName)
   fmt.Println("LogerMiddleware: " + fileName)

   // 写入文件
   src, err := os.OpenFile(fileName, os.O_RDWR|os.O_CREATE|os.O_APPEND, 0777)
   if err != nil {
       fmt.Println("err", err)
   }
   // 实例化
   logger := logrus.New()
   //设置日志级别
   logger.SetLevel(logrus.DebugLevel)
   //设置输出
   logger.Out = src

   // 设置 rotatelogs
   logWriter, err := rotatelogs.New(
       // 分割后的文件名称
       fileName+".%Y-%m-%d.log",
       // 生成软链，指向最新日志文件
       rotatelogs.WithLinkName(fileName),
       // 设置最大保存时间(7天)
       rotatelogs.WithMaxAge(7*24*time.Hour),
       // 设置日志切割时间间隔(1天)
       rotatelogs.WithRotationTime(24*time.Hour),
   )

   writeMap := lfshook.WriterMap{
       logrus.InfoLevel:  logWriter,
       logrus.FatalLevel: logWriter,
       logrus.DebugLevel: logWriter,
       logrus.WarnLevel:  logWriter,
       logrus.ErrorLevel: logWriter,
       logrus.PanicLevel: logWriter,
   }

   logger.AddHook(lfshook.NewHook(writeMap, &logrus.TextFormatter{
       TimestampFormat: "15:04:05",
   }))

   return func(c *gin.Context) {
       //开始时间
       startTime := time.Now()
       //处理请求
       c.Next()
       //结束时间
       endTime := time.Now()
       logger.Infof("%3d | %8v | %13s | %s | %s | %s | %s | %s |",
           c.Writer.Status(),
           endTime.Sub(startTime),
           c.ClientIP(),
           c.Request.Method,
           c.Request.RequestURI,
           c.Request.Proto,
           c.Request.UserAgent(),
           c.Request.Referer(),
       )

   }
}

Answer 1

时间都不一样，应该是两次独立的请求吧

Answer 2

你给logger加的hook也写入了日志吧

Answer 3

大佬 你最后解决了没 我现在也是打印两条日志记录

Answer 4

改成 logger.Out = logWriter， writeMap 删掉不用重复设置。
