理解go语言 协程之间的通讯

go已经越来越被重视了,特别适合大型互联网公司基础服务的编写,高效,高并发,可以同时允许多个明星出轨,多个明星结婚 都不在话下,下面介绍下GO协程通讯的过程

直接上代码

package main

import (
	"fmt"
	"time"
)

func main() {
	//关于channel和routine的理解,一个描述挖矿的程序。它包含三个函数,分别负责执行寻矿、挖矿和练矿任务。
	//在本例中,我们用一组字符串表示 rock(矿山) 和 ore(矿石),每个函数都以它们作为输入,并返回一组 “处理过的” 字符串。

	theMine := [5]string{"rock", "ore", "rock", "ore", "ore"}
	//建立两个管道
	oreChannel := make(chan string)
	mineChannel := make(chan string)

	//Finder  找到石头后发送到管道oreChannel
	go func(mine [5]string) {
		for _, item := range mine {
			if item == "rock" {
				oreChannel <- item //send item on oreChannel
			}
		}
	}(theMine)

	//Ore Breaker
	//从管道oreChannel 中读取 ore原石
	/*go func() {
		for i := 0; i < 3; i++ {
			foundOre := <-oreChannel //read from oreChannel
			fmt.Println("From Finder", foundOre)
			mineChannel <- "mineOre" //send to mineOreChan
		}
	}() */
	go func() {
		for foundOre := range oreChannel {
			fmt.Println("Miner: Received " + foundOre + " from finder")
			mineChannel <- foundOre

		}
	}()

	//Smelter
	//接收
	go func() {
		for i := 0; i < 3; i++ {
			mineOre := <-mineChannel //read from mineChannel
			fmt.Println("From Miner:", mineOre)
			fmt.Println("From Smelter:Ore is smelter")
		}

	}()
	<-time.After(time.Second * 5) //
}
