区分Terminal和Hook Zerolog Go中的错误级别日志(log)输出

我设法解决了将日志(log)级别发送到mongoDB同时仅在终端上显示错误日志(log)的问题. 如果其他人也面临类似的希望，此代码将有所帮助.

func ConsoleWriter() zerolog.ConsoleWriter {
    consoleWriter := zerolog.ConsoleWriter{Out: os.Stdout, NoColor: true, TimeFormat: time.RFC3339}

    return consoleWriter
}

func InitLogger(ctx context.Context, mc *mongo.Client, productType int) *zerolog.Logger {
    once.Do(func() {
        var multi zerolog.LevelWriter

        multi = zerolog.MultiLevelWriter(ZerologOut{
            mClient:     mc,
        })

        
        logger := zerolog.New(multi).With().Timestamp().Logger()

        zLog = &logger

    })
    return zLog
}


type ZerologOut struct {
    mClient     *mongo.Client
}


func (zo ZerologOut) Write(p []byte) (n int, err error) {
    return os.Stdout.Write(p)
}


func (zo ZerologOut) WriteLevel(level zerolog.Level, p []byte) (n int, err error) {

    message := string(p)

    logData := LogData{}

    err = zo.sendLogToMongoDB(context.Background(), message, logData)
    if err != nil {
        return 0, err
    }

    if level == zerolog.ErrorLevel {
        return ConsoleWriter().Write(p)
    }

    return len(p), nil
}
