[GO]ticker的使用

package main

import (
    "time"
    "fmt"
)

//ticker是一个定时触发的计时器，它会以一个间隔往channel发送整一个事件（当时时间），而channel的接收者可以以固定的时间间隔从channel中读取事件

func main() {
    ticker := time.NewTicker(time.Second)
    i :=
    for true {
        time := <-ticker.C
        i++
        fmt.Printf("i = %d, time = %v\n", i, time)
        if i== {
            ticker.Stop()
            break
        }
    }
}

执行的结果为

i = , time = -- ::38.9705836 + CST m=+1.001708201
i = , time = -- ::39.9702884 + CST m=+2.001413001
i = , time = -- ::40.9699923 + CST m=+3.001116901
i = , time = -- ::41.970699 + CST m=+4.001823601
i = , time = -- ::42.9704029 + CST m=+5.001527501
