Go语言中的Zap日志库

19岁开始学习2025-10-06 22:08

zap

USE

go get -u go.uber.org/zap

go 复制代码

package main

import (
	"go.uber.org/zap"
	"net/http"
)

var logger *zap.Logger

func main() {
	InitLogger()
	defer logger.Sync() //关闭之前 刷新缓冲区的内容到里面
	simpleHttpGet("www.baidu.com")
	simpleHttpGet("http://www.baidu.com")
}

func InitLogger() {
	logger, _ = zap.NewProduction()
}

func simpleHttpGet(url string) {
	resp, err := http.Get(url)
	if err != nil {
		logger.Error(
			"Error fetching url..",
			zap.String("url", url),
			zap.Error(err))
	} else {
		logger.Info("Success..",
			zap.String("statusCode", resp.Status),
			zap.String("url", url))
		resp.Body.Close()
	}
}

日志写入文件

日志切片 go get gopkg.in/natefinch/lumberjack.v2

go 复制代码

package main

import (
	"net/http"

	"go.uber.org/zap"
	"go.uber.org/zap/zapcore"
	"gopkg.in/natefinch/lumberjack.v2"
)

var sugarLogger *zap.SugaredLogger

func main() {
	InitLogger()
	defer sugarLogger.Sync()
	simpleHttpGet("www.sogo.com")
	simpleHttpGet("http://www.sogo.com")
}

func InitLogger() {
	writeSyncer := getLogWriter()
	encoder := getEncoder()
	core := zapcore.NewCore(encoder, writeSyncer, zapcore.DebugLevel)

	logger := zap.New(core, zap.AddCaller()) //zap.AddCaller 添加调用者
	sugarLogger = logger.Sugar()
}

func getEncoder() zapcore.Encoder {
	encoderConfig := zap.NewProductionEncoderConfig()
	encoderConfig.EncodeTime = zapcore.ISO8601TimeEncoder
	encoderConfig.EncodeLevel = zapcore.CapitalLevelEncoder
	return zapcore.NewConsoleEncoder(encoderConfig)
}

func getLogWriter() zapcore.WriteSyncer {
	lumberJackLogger := &lumberjack.Logger{
		Filename:   "./test.log",
		MaxSize:    200,   //MV
		MaxBackups: 5,     //最大备份书来给你
		MaxAge:     30,    //最大备份天数
		Compress:   false, //是否压缩
	}
	return zapcore.AddSync(lumberJackLogger)
}

func simpleHttpGet(url string) {
	sugarLogger.Debugf("Trying to hit GET request for %s", url)
	resp, err := http.Get(url)
	if err != nil {
		sugarLogger.Errorf("Error fetching URL %s : Error = %s", url, err)
	} else {
		sugarLogger.Infof("Success! statusCode = %s for URL %s", resp.Status, url)
		resp.Body.Close()
	}
}

Gin使用zip

gin 框架使用的是engine.Use(Logger(), Recovery())这个做为日志
使用gin.New() 去实例化一个然后使用项目
后续会去更新
