go zap日志组件，日志切分、日志记录

zap log 初始化：设置 日志文件每 5MB 会切割并且在当前目录下最多保存 5 个备份,并且会将旧文档保存30天

使用 lumberjack 做日志切分

package main

import (
	"github.com/natefinch/lumberjack"
	"go.uber.org/zap"
	"go.uber.org/zap/zapcore"
	"net/http"
)

var logger *zap.Logger
var sugarLogger *zap.SugaredLogger



func InitLogger() {
	encoder := getEncoder()
	writerSyncer := getLogWriter()
	core := zapcore.NewCore(encoder,writerSyncer,zapcore.DebugLevel)
	logger = zap.New(core,zap.AddCaller())
	sugarLogger = logger.Sugar()
}

// core 三个参数之  编码
func getEncoder() zapcore.Encoder {
	encoderConfig := zap.NewProductionEncoderConfig()
	encoderConfig.EncodeTime = zapcore.ISO8601TimeEncoder
	encoderConfig.EncodeLevel = zapcore.CapitalLevelEncoder
	return zapcore.NewConsoleEncoder(encoderConfig)
}

// core 三大核心之  路径
func getLogWriter() zapcore.WriteSyncer {
	lumberJackLogger := &lumberjack.Logger{
		Filename:   "E:/test.log",
		MaxSize:    10,
		MaxBackups: 5,
		MaxAge:     30,
		Compress:   false,
	}
	return zapcore.AddSync(lumberJackLogger)
}

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


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()
	}
}
