我正在嘗試編寫一個程序，該程序?qū)⒃谔囟〞r間間隔內(nèi)連續(xù)調(diào)用一個方法。我正在使用 cron 庫來嘗試實現(xiàn)這一點，但是當(dāng)我運行該程序時，它只會執(zhí)行并完成而沒有任何輸出。下面是我正在嘗試做的一個基本示例。非常感謝您的幫助！package mainimport ( "fmt" "github.com/robfig/cron")func main() { c := cron.New() c.AddFunc("1 * * * * *", RunEverySecond) c.Start()}func RunEverySecond() { fmt.Println("----")}

為此使用外部包是矯枉過正的，該time包具有您需要的一切：
package main
import (
"fmt"
"time"
)
func main() {
go func() {
c := time.Tick(1 * time.Second)
for range c {
// Note this purposfully runs the function
// in the same goroutine so we make sure there is
// only ever one. If it might take a long time and
// it's safe to have several running just add "go" here.
RunEverySecond()
}
}()
// Other processing or the rest of your program here.
time.Sleep(5 * time.Second)
// Or to block forever:
//select {}
// However, if doing that you could just stick the above for loop
// right here without dropping it into a goroutine.
}
func RunEverySecond() {
fmt.Println("----")
}
