Log logrus third party library usage

One 、 install

github.com/sirupsen/logrus

logrus Use profile

 

{
  "log_path":"logs",
  "log_name":"gin_project.log",
  "log_level":"info"
}

Two 、 Load the configuration

 

package logs_source

import (
	"os"
	"io/ioutil"
	"fmt"
	"encoding/json"
)

type LogConfig struct {
	LogPath string `json:"log_path"`
	LogName string `json:"log_name"`
	LogLevel string `json:"log_level"`
}

func LoadLogConfig()  *LogConfig{

	log_conf := LogConfig{}


	file,err := os.Open("conf/log_conf.json")

	if err != nil {
		panic(err)
	}

	defer file.Close()

	byte_datas,err2 := ioutil.ReadAll(file)


	if err2 != nil {
		panic(err2)
	}

	err3 := json.Unmarshal(byte_datas,&log_conf)
	if err3 != nil {
		fmt.Println(err3)
	}

	fmt.Println(log_conf)

	return &log_conf
}

  3、 ... and 、 initialization

package logs_source

import (
	"github.com/sirupsen/logrus"
	"os"
	"fmt"
)


//  Create an instance 
var Log = logrus.New()

func init()  {

	log_conf := LoadLogConfig()

	//  Set log output file 
	log_dir := log_conf.LogPath + "/" +log_conf.LogName
	fmt.Println(log_dir)
	file,err := os.OpenFile(log_dir,os.O_APPEND|os.O_WRONLY,os.ModeAppend)

	if err != nil {
		panic(err)
	}

	Log.Out = file


	//  Set the log level 

	level_mapping := map[string]logrus.Level{
		"trace":logrus.TraceLevel,
		"debug":logrus.DebugLevel,
		"info":logrus.InfoLevel,
		"warn":logrus.WarnLevel,
		"error":logrus.ErrorLevel,
		"fatal":logrus.FatalLevel,
		"panic":logrus.PanicLevel,
	}

	Log.SetLevel(level_mapping[log_conf.LogLevel])

	//  Log formatting 
	Log.SetFormatter(&logrus.TextFormatter{})


}

//func main() {
//	Log.Info("xxxxx")
//}

logs.Log.Warn(" This is a warnning Level of logging ")
logs.Log.WithFields(logrus.Fields{
            "msg": " Test error ",
        }).Warn(" This is a warnning Level of logging ")
