Logger config

type Fields

type Fields map[string]interface{}

Fields Type to pass when we want to call WithFields for structured logging

type Logger

type Logger interface {
	Debug(args ...interface{})
	Debugf(format string, args ...interface{})

	Info(args ...interface{})
	Infof(format string, args ...interface{})

	Warn(args ...interface{})
	Warnf(format string, args ...interface{})

	Error(args ...interface{})
	Errorf(format string, args ...interface{})

	Fatal(args ...interface{})
	Fatalf(format string, args ...interface{})

	Panicf(format string, args ...interface{})

	WithFields(keyValues Fields) Logger
}

Logger is our contract for the logger

func GetLogger

func GetLogger() Logger

func Init

func Init(cfg *Config) Logger

Init init log

func WithFields

func WithFields(keyValues Fields) Logger

WithFields logger output more field, eg:

contextLogger := log.WithFields(log.Fields{"key1": "value1"})
contextLogger.Info("print multi field")

or more sample to use:

log.WithFields(log.Fields{"key1": "value1"}).Info("this is a test log")
log.WithFields(log.Fields{"key1": "value1"}).Infof("this is a test log, user_id: %d", userID)
