修改日志

2019-07-30 优化了 logger.go，日志新增了返回数据，见最新代码包。

配置

// 日志记录到文件
func LoggerToFile() gin.HandlerFunc {

    logFilePath := config.Log_FILE_PATH
    logFileName := config.LOG_FILE_NAME

    //日志文件
    fileName := path.Join(logFilePath, logFileName)

    //写入文件
    src, err := os.OpenFile(fileName, os.O_APPEND|os.O_WRONLY, os.ModeAppend)
    if err != nil {
        fmt.Println("err", err)
    }

    //实例化
    logger := logrus.New()

    //设置输出
    logger.Out = src

    //设置日志级别
    logger.SetLevel(logrus.DebugLevel)

    //设置日志格式
    logger.SetFormatter(&logrus.TextFormatter{})

    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()

        // 执行时间
        latencyTime := endTime.Sub(startTime)

        // 请求方式
        reqMethod := c.Request.Method

        // 请求路由
        reqUri := c.Request.RequestURI

        // 状态码
        statusCode := c.Writer.Status()

        // 请求IP
        clientIP := c.ClientIP()

        // 日志格式
        logger.Infof("| %3d | %13v | %15s | %s | %s |",
            statusCode,
            latencyTime,
            clientIP,
            reqMethod,
            reqUri,
        )
    }
}

运行

下载源码后，请先执行 dep ensure 下载依赖包！
