package main

import (
	"fmt"
	"time"
)

type info struct {
	Ch chan int
}

func goRun1(v *info) {
	time.Sleep(time.Second *3)
	v.Ch <- 1
	fmt.Println("goRun1我这里等待了3秒钟后打印")
}

func goRun2()  {
	time.Sleep(time.Second *3)
	fmt.Println("goRun2我这里等待了3秒钟后打印")
}

func main()  {
	var ch chan int
	infoStruct := &info{Ch:ch}

	go goRun1(infoStruct)
	go goRun2()
	for {
		select {
		case val, ok := <-ch:
			if ok {
				fmt.Println("这里是返回的ch值:", val)
				return
			}
		case <-time.After(time.Second * 5):
			fmt.Println("超时结束")
			return
		}
	}
}

为什么我的 goRun1 函数并未执行,并且ch的值为什么没有被select 获取到呢?
