timeout.go

package main
 
import (
	"fmt"
	"time"
)
 
func main() {
	timeout := time.After(time.Second * 10)
	finish := make(chan bool)
	count := 1
	go func() {
		for {
			select {
			case <-timeout:
				fmt.Println("timeout")
				finish <- true
				return
			default:
				fmt.Printf("haha %d\n", count)
				count++
			}
			time.Sleep(time.Second * 1)
		}
	}()
 
	<-finish
 
	fmt.Println("Finish")
}
