log

zap框架二次封装

使用

func main() {
    // 新建句柄
    field := zapcore.Field{
        Key:    "module_name",
        Type:   zapcore.StringType,
        String: "serverName",
    }
    bizLog := New("default",
        WithPath("./storage/logs"),
        WithTimeFormat("2006-01-02 15:04:05"),
        WithLevel(zapcore.InfoLevel),
        WithPreName("biz_"),
        WithEncoderJSON(false),
        WithFields(field))
    
    // 记录日志
    bizLog.Debug("this is SugarDebug")
    bizLog.Info("this is SugarInfo")
    bizLog.Warn("this is SugarWarn")
    bizLog.Error("this is SugarError")
    
    bizLog.Debugf("this is %s", "Debugf")
    bizLog.Infof("this is %s", "Infof")
    bizLog.Warnf("this is %s", "Warn")
    bizLog.Errorf("this is %s", "Errorf")
    
    bizLog.Debugw("this is Debugw", "k", "Debugw")
    bizLog.Infow("this is Infow", "k", "Infow")
    bizLog.Warnw("this is Warnw", "k", "Warnw")
    bizLog.Errorw("this is Errorw", "k", "Errorw")
}

全局配置

修改默认配置，之后新建的日志，将默认使用这些配置

SetGlobalConf(options ...ConfigOption), 配置项使用WithXxx()

• WithPath 日志路径，默认为 .
• WithLevel 最低打印级别，默认为 debug
• WithLogInConsole 是否打印到控制台，默认为 false
• WithFields 该日志都加的字段，默认为空
• WithEncoderJSON 是否为json格式日志，默认为 true
• WithTimeFormat 时间格式，默认为 2006-01-02T15:04:05Z07:00
• WithPreName 日志前缀，默认为 biz_

func main() {
    field := zapcore.Field{
        Key:    "module_name",
        Type:   zapcore.StringType,
        String: "helloLog",
    }
    // 设置默认配置后，之后新建的所有日志都默认使用该配置
    SetDefaultConf(
    	WithPath("./storage/logs"),
        WithTimeFormat("2006-01-02 15:04:05"),
        WithLevel(zapcore.InfoLevel),
        WithPreName("biz_"),
        WithEncoderJSON(false),
        WithFields(field))
    
    // 新建日志
    // ……
}

带有请求id的日志

func main() {
    k := "request_id"
    c := context.WithValue(context.Background(), k, "r61f0ed0d70098_Zw8R1aoyl4tGeB4HMV")
    
    // 告知log如何从上下文获取请求id
    SetDefaultConf(WithRequestIdKey(k))
    
    l := New("trace")
    l.DebugWithTrace(c,"this is SugarDebug")
    l.InfoWithTrace(c,"this is SugarInfo")
    l.WarnWithTrace(c,"this is SugarWarn")
    l.ErrorWithTrace(c,"this is SugarError")
    
    l.DebugfWithTrace(c,"this is %s", "Debugf")
    l.InfofWithTrace(c,"this is %s", "Infof")
    l.WarnfWithTrace(c,"this is %s", "Warn")
    l.ErrorfWithTrace(c,"this is %s", "Errorf")
    
    l.DebugwWithTrace(c,"this is Debugw", "k", "Debugw")
    l.InfowWithTrace(c,"this is Infow", "k", "Infow")
    l.WarnwWithTrace(c,"this is Warnw", "k", "Warnw")
    l.ErrorwWithTrace(c,"this is Errorw", "k", "Errorw")
}
