logrus简单使用教程

 初始化logrus，简单配置

package logger
 
import (
	"github.com/sirupsen/logrus"
	"os"
)
 
func Init() {
	var log = logrus.New()
	log.Formatter = new(logrus.TextFormatter)
	log.Formatter.(*logrus.TextFormatter).DisableTimestamp = false // remove timestamp from test output
	log.Formatter.(*logrus.TextFormatter).FullTimestamp = true
	log.Formatter.(*logrus.TextFormatter).TimestampFormat = "2006-01-02 15:04:05" //default
	log.Formatter.(*logrus.TextFormatter).DisableColors = false                   // remove colors
	logrus.SetFormatter(log.Formatter)
 
	logrus.SetLevel(logrus.TraceLevel)
	logrus.SetOutput(os.Stdout)
}

 调用logrus

package main
 
import (
	"github.com/sirupsen/logrus"
	"study/logger/logger"
)
 
var log = logrus.WithField("prefix", "main")
 
func main() {
	logger.Init()
	log.WithFields(logrus.Fields{
		"animal": "walrus",
		"number": 0,
	}).Trace("Went to the beach")
 
	log.WithFields(logrus.Fields{
		"animal": "walrus",
		"number": 8,
	}).Debug("Started observing beach")
 
	log.WithFields(logrus.Fields{
		"animal": "walrus",
		"size":   10,
	}).Info("A group of walrus emerges from the ocean")
 
	log.WithFields(logrus.Fields{
		"omg":    true,
		"number": 122,
	}).Warn("The group's number increased tremendously!")
 
	log.WithFields(logrus.Fields{
		"temperature": -4,
	}).Debug("Temperature changes")
 
	log.WithFields(logrus.Fields{
		"animal": "orca",
		"size":   9009,
	}).Panic("It's over 9000!")
}
