使用go里面实现了一个并发的时钟服务器

package main

import (
	"io"
	"log"
	"net"
	"time"
)
func handleConn(conn net.Conn ){
	defer  conn.Close();
	for {
		_,err := io.WriteString(conn,time.Now().Format("15:04:05\n"));
		if err !=nil {
			return;
		}
		time.Sleep(1 * time.Second);
	}
}
func main(){
	listener,err:= net.Listen("tcp","localhost:8000");
	if err != nil {
		log.Fatal("error");
	}
	for {
		conn,err:= listener.Accept();//循环阻塞
		if err != nil {
			log.Fatal("connect is break");
			continue;
		}
		handleConn(conn);
	}

}
