英文:
Run cron on weekdays only
问题
目前有以下的cron代码，来源于这里。我想让它只在工作日运行。
package main
import (
"fmt"
"time"
)
const INTERVAL_PERIOD time.Duration = 24 * time.Hour
const HOUR_TO_TICK int = 23
const MINUTE_TO_TICK int = 21
const SECOND_TO_TICK int = 03
type jobTicker struct {
t *time.Timer
}
func getNextTickDuration() time.Duration {
now := time.Now()
nextTick := time.Date(now.Year(), now.Month(), now.Day(), HOUR_TO_TICK, MINUTE_TO_TICK, SECOND_TO_TICK, 0, time.Local)
if nextTick.Before(now) {
nextTick = nextTick.Add(INTERVAL_PERIOD)
}
return nextTick.Sub(time.Now())
}
func NewJobTicker() jobTicker {
fmt.Println("new tick here")
return jobTicker{time.NewTimer(getNextTickDuration())}
}
func (jt jobTicker) updateJobTicker() {
fmt.Println("next tick here")
jt.t.Reset(getNextTickDuration())
}
func main() {
jt := NewJobTicker()
for {
<-jt.t.C
fmt.Println(time.Now(), "- just ticked")
jt.updateJobTicker()
}
}
如何使其只在工作日运行？

Currently have this cron code below which is from here Trying to make this can be so it can run the job only on weekdays only.
package main
import (
"fmt"
"time"
)
const INTERVAL_PERIOD time.Duration = 24 * time.Hour
const HOUR_TO_TICK int = 23
const MINUTE_TO_TICK int = 21
const SECOND_TO_TICK int = 03
type jobTicker struct {
t *time.Timer
}
func getNextTickDuration() time.Duration {
now := time.Now()
nextTick := time.Date(now.Year(), now.Month(), now.Day(), HOUR_TO_TICK, MINUTE_TO_TICK, SECOND_TO_TICK, 0, time.Local)
if nextTick.Before(now) {
nextTick = nextTick.Add(INTERVAL_PERIOD)
}
return nextTick.Sub(time.Now())
}
func NewJobTicker() jobTicker {
fmt.Println("new tick here")
return jobTicker{time.NewTimer(getNextTickDuration())}
}
func (jt jobTicker) updateJobTicker() {
fmt.Println("next tick here")
jt.t.Reset(getNextTickDuration())
}
func main() {
jt := NewJobTicker()
for {
<-jt.t.C
fmt.Println(time.Now(), "- just ticked")
jt.updateJobTicker()
}
}
How can I make this only run on the weekdays only ?

你应该在**getNextTickDuration()**函数中检查星期几。代码可能如下所示：
func getNextTickDuration() time.Duration {
now := time.Now()
nextTick := time.Date(now.Year(), now.Month(), now.Day(), HOUR_TO_TICK, MINUTE_TO_TICK, SECOND_TO_TICK, 0, time.Local)
for nextTick.Before(now) || nextTick.Weekday() == time.Saturday || nextTick.Weekday() == time.Sunday {
nextTick = nextTick.Add(INTERVAL_PERIOD)
}
return nextTick.Sub(time.Now())
}
请注意，这是一个示例代码，其中的HOUR_TO_TICK、MINUTE_TO_TICK、SECOND_TO_TICK和INTERVAL_PERIOD是需要根据你的具体需求进行定义的变量。
英文:
You should check for day of the week inside your getNextTickDuration() function. It may look like this
func getNextTickDuration() time.Duration {
now := time.Now()
nextTick := time.Date(now.Year(), now.Month(), now.Day(), HOUR_TO_TICK, MINUTE_TO_TICK, SECOND_TO_TICK, 0, time.Local)
for nextTick.Before(now) || nextTick.Weekday() == time.Saturday || nextTick.Weekday() == time.Sunday {
nextTick = nextTick.Add(INTERVAL_PERIOD)
}
return nextTick.Sub(time.Now())
}
