logrus的使用

基础1

package main

import (
	log "github.com/sirupsen/logrus"
)

func main() {
	log.WithFields(log.Fields{
		"animal": "dog",
	}).Info("一条舔狗出现了。")

	log.SetLevel(log.TraceLevel) //输出级别
	//log.SetReportCaller(true)//行号
	//log.SetFormatter(&log.JSONFormatter{})
	log.SetFormatter(&log.TextFormatter{})//输出格式 默认
	log.Trace("Trace")
	log.Debug("Debug")
	log.Info("Info")
	log.Warn("Warn")
	log.Error("Error")

	cnt := 100
	rst := true
	log.WithFields(log.Fields{
		"event":   "bledisconnect",
		"numbers": cnt,
		"key":     rst,
	}).Fatal("Failed to bledisconnect")

	// 记完日志后会调用os.Exit(1)
	log.Fatal("Fatal")
	// 记完日志后会调用 panic()
	log.Panic("Panic")
}

文件

package main

import (
	"os"
	"time"

	"github.com/sirupsen/logrus"
)

var log = logrus.New()

func main() {

	file, err := os.OpenFile("log-"+time.Now().Format("2006-01-02")+".log", os.O_CREATE|os.O_WRONLY, 0666)
	if err == nil {
		log.Out = file
	} else {
		log.Info("Failed to log to file")
	}

	log.WithFields(logrus.Fields{
		"filename": "123.txt",
	}).Info("打开文件失败")
}

logrus日志库简单使用-Go-优雅人生

package main

import (
	log "github.com/sirupsen/logrus"
)

func main() {

	log.WithFields(log.Fields{
		"animal": "dog",
	}).Info("一条舔狗出现了。")

	log.SetLevel(log.TraceLevel) //输出级别
	//log.SetReportCaller(true)//行号
	//log.SetFormatter(&log.JSONFormatter{})
	//log.SetFormatter(&log.TextFormatter{})//输出格式 默认
	customFormatter := new(log.TextFormatter)
	customFormatter.FullTimestamp = true                    // 显示完整时间
	customFormatter.TimestampFormat = "2006-01-02 15:04:05" // 时间格式
	customFormatter.DisableTimestamp = false                 // 禁止显示时间
	customFormatter.DisableColors = false                   // 禁止颜色显示

	log.SetFormatter(customFormatter)
	log.Trace("Trace")
	log.Debug("Debug")
	log.Info("Info")
	log.Warn("Warn")
	log.Error("Error")

	cnt := 100
	rst := true
	log.WithFields(log.Fields{
		"event":   "bledisconnect",
		"numbers": cnt,
		"key":     rst,
	}).Fatal("Failed to bledisconnect")

	// 记完日志后会调用os.Exit(1)
	log.Fatal("Fatal")
	// 记完日志后会调用 panic()
	log.Panic("Panic")
}
