Golang-超时机制Timeout和心跳HeartBeart--demo

1、超时机制Timeout

package mian

func workerTimeout(start chan bool) {
	timeout := time.After(10 * time.Second)
	for {
		select {
				// … do some stuff
		case <- timeout:
			return
		}
	}
}
fumc main() {
    var intChan chan bool
     intChan = make(chan bool, 1)
    workerTimeout(intChan)
}

　　

2、心跳HeartBeart 

 

　　与timeout实现类似，下面是一个简单的心跳select实现：

　　

package mian

func workerHeartbeat(start chan bool) {
        heartbeat := time.Tick(1 * time.Second)
        for {
                select {
                     // … do some stuff
				case <- heartbeat:
					fmt.Println("*")
                    //… do heartbeat stuff
                }
        }
}

fumc main() {
    var intChan chan bool
     intChan = make(chan bool, 1)
    workerHeartbeat(intChan)
}
