您可以使用WithClock
选项来定义您自己的时钟,提供您想要的时间功能.例如使用恒定时钟(总是返回类似2077-01-23T10:15:13Z
的日期).这个例子基于zap
个库中的clock_test.go
个.
package main
import (
"time"
"go.uber.org/zap"
"go.uber.org/zap/zapcore"
)
type constantClock time.Time
func (c constantClock) Now() time.Time { return time.Time(c) }
func (c constantClock) NewTicker(d time.Duration) *time.Ticker {
return &time.Ticker{}
}
func main() {
date := time.Date(2077, 1, 23, 10, 15, 13, 441, time.UTC) // clock will always return that date
clock := constantClock(date)
config := zap.NewProductionConfig()
// this is just for sugar, to display a readable date instead of an epoch time
config.EncoderConfig.EncodeTime = zapcore.TimeEncoderOfLayout(time.RFC3339)
logger, _ := config.Build()
logger = logger.WithOptions(zap.WithClock(clock))
defer logger.Sync()
logger.Info("Hello")
}
您可以在这里使用该代码:https://go.dev/play/p/8oLQm7mXrlD,它将打印如下:
{"level":"info","ts":"2077-01-23T10:15:13Z","caller":"sandbox1129194476/prog.go:29","msg":"Hello"}
个
从那里,您可以定制您的时钟根据需要(Now()
和NewTicker()
方法),以提供您将期望的时间.
