Go語言可輸出按分隔符分割格式（如CSV）日誌並按時間切分的日誌模塊bizlogger

bizlogger是一款可輸出CSV日誌並按時間切分的日誌模塊，分割符可定製。goroutine安全。日誌字符串拼接採用先計算總長度再一次性分配內存的方法來提升效率。按時間切分功能利用的是logrotator來實現的。

用法：

package main

import (
	"fmt"
	"github.com/pochard/bizlogger"
	"time"
)

func main() {
	// rollup every 20 minutes. And the log line is separated by ","
	logger, err := bizlogger.NewTabLogger("/data/web_log/click1-%Y%m%d-%H%M.log", 20*time.Minute, ",")
	if err != nil {
		fmt.Printf("%v", err)
		return
	}
	defer logger.Close()

	sl := make([]string, 4)
	sl[0] = "410001"
	sl[1] = "1583893679"
	sl[2] = "183.199.195.151"
	sl[3] = "C03FD5AAB4CA"

	for i := 0; i != 10; i++ {
		err := logger.Log(sl)
		if err != nil {
			fmt.Printf("%v", err)
		}
	}
}

輸出日誌：

click1-20200328-0920.log
click1-20200328-0940.log
click1-20200328-1000.log

日誌內容：

410001,1583893679,183.199.195.151,C03FD5AAB4CA
