GoFrame 日志組件-Flags特性

2022-03-29 17:09 更新

?flags?用于控制日志組件的額外特性開(kāi)關(guān),這些屬性使用常量進(jìn)行組合控制,包括:

F_ASYNC      = 1 << iota // 開(kāi)啟日志異步輸出
F_FILE_LONG              // 打印調(diào)用行號(hào)信息,完整絕對(duì)路徑,例如:/a/b/c/d.go:23
F_FILE_SHORT             // 打印調(diào)用行號(hào)信息,僅打印文件名,例如:d.go:23,覆蓋 F_FILE_LONG.
F_TIME_DATE              // 打印當(dāng)前日期,如:2009-01-23
F_TIME_TIME              // 打印當(dāng)前時(shí)間,如:01:23:23
F_TIME_MILLI             // 打印當(dāng)前時(shí)間+毫秒,如:01:23:23.675
F_TIME_STD = F_TIME_DATE | F_TIME_MILLI // (默認(rèn))打印當(dāng)前日期+時(shí)間+毫秒,如:2009-01-23 01:23:23.675

使用示例:

package main

import (
	"context"

	"github.com/gogf/gf/v2/os/glog"
)

func main() {
	ctx := context.TODO()
	l := glog.New()
	l.SetFlags(glog.F_TIME_TIME | glog.F_FILE_SHORT)
	l.Print(ctx, "time and short line number")
	l.SetFlags(glog.F_TIME_MILLI | glog.F_FILE_LONG)
	l.Print(ctx, "time with millisecond and long line number")
	l.SetFlags(glog.F_TIME_STD | glog.F_FILE_LONG)
	l.Print(ctx, "standard time format and long line number")
}

執(zhí)行后,終端輸出結(jié)果為:

PS C:\hailaz\test> go run .\main.go
16:05:35 main.go:13: time and short line number 
16:05:35.108 C:/hailaz/test/main.go:15: time with millisecond and long line number 
2022-01-05 16:05:35.109 C:/hailaz/test/main.go:17: standard time format and long line number
