Using nxlog4go for Testing Environment-优快云博客

本文介绍了一个简单的 Go 语言日志记录库 nxlog4go 的使用方法，展示了如何通过不同的日志级别记录信息，并提供了设置显示级别的示例代码。

nxlog4go is very simple to use without any configuring, setting. For example:


package main

import (
    "time"
    log "github.com/ccpaging/nxlog4go"
)


func main() {
    log.Fine("This should be omitted as default.")
    log.Debug("The time is now: %s", time.Now().Format("15:04:05 MST 2006/01/02"))
    log.Info("The time is now: %s", time.Now().Format("15:04:05 MST 2006/01/02"))
    log.Warn("The time is now: %s", time.Now().Format("15:04:05 MST 2006/01/02"))
    log.Critical("The time is now: %s", time.Now().Format("15:04:05 MST 2006/01/02"))
}

Compatibility with go log

The most programmer always use go log for testing. nxlog4go aimed the replacement of go log.

Log Function	Level	After
Crash, Crashf	CRITICAL, panic	panic
Exit, Exitf	ERROR, exit	exit
Stderr, Stderrf	ERROR
Stdout, Stdoutf	INFO

New log functions

Log Function	Level	Default
Finest(...)	0	Omit
Fine(...)	1	Omit
Debug(...)	2
Trace(...)	3
Info(...)	4
Warn(...)	5
Error(...)	6
Critical(...)	7

Set display level

For example:

    log.GetLogger().SetLevel(log.FINE)
    log.Fine("This should be not omitted now.")

log.GetLogger() return the point of default Global Logger.

SetLevel(log.FINE) sets level to log.FINE.
