golang-channel读取数据

当读取channel时，channel不会关闭而是持续性监听（for 循环且intChan开启）

package main

import (
	"fmt"
	"time"
)

// WriteData
func writeData(intChan chan int)  {
	for i:=1;i <= 50;i++{
		//放入数据
		intChan <- i
		fmt.Printf("writeData 写入数据=%v\n",i)
		time.Sleep(500)
	}
	close(intChan) //关闭
}

//readData
func readData(intChan chan int,exitChan chan bool){
	for  {
		v,ok := <- intChan
		if !ok{
			break
		}
		fmt.Printf("readData 读到数据=%v\n",v)
	}
	//读完数据后人物完成
	exitChan <- true
	close(exitChan)

}

func main(){

	//创建两个管道
	intChan := make(chan int,50)
	exitChan := make(chan bool,1)

	go writeData(intChan)
	go readData(intChan,exitChan)

	//time.Sleep(time.Second * 10)

	for  {
		_,ok := <- exitChan
		if !ok{
			break
		}
	}
}
