flags 用于控制日志组件的额外特性开关,这些属性使用常量进行组合控制,包括:

F_ASYNC      = 1 << iota // 开启日志异步输出
F_FILE_LONG // 打印调用行号信息,完整绝对路径,例如:/a/b/c/d.go:23
F_FILE_SHORT // 打印调用行号信息,仅打印文件名,例如:d.go:23,覆盖 F_FILE_LONG.
F_TIME_DATE // 打印当前日期,如:2009-01-23
F_TIME_TIME // 打印当前时间,如:01:23:23
F_TIME_MILLI // 打印当前时间+毫秒,如:01:23:23.675
F_TIME_STD = F_TIME_DATE | F_TIME_MILLI // (默认)打印当前日期+时间+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")
}

执行后,终端输出结果为:

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
