Go语言实现TCP并发传输

Server

listener,err:=net.Listen("tcp","127.0.0.1:8000")
	if err!=nil {
		fmt.Print(err)
		return
	}
	defer listener.Close()
	for  {
		conn,err:=listener.Accept()
		if err!=nil {
			fmt.Print(err)
			return
		}
		fmt.Print(conn.RemoteAddr())
		go func() {
			defer conn.Close()
			buf:=make([]byte,1024)
			for  {
				n,err:=conn.Read(buf)
				conn.Write([]byte(strings.ToUpper(string(buf[:n]))))
				if err==io.EOF {
					return
				}
			}
		}()
	}

Client

conn,err:=net.Dial("tcp","127.0.0.1:8000")
	if err!=nil {
		fmt.Print(err)
		return
	}
	defer conn.Close()
	go func() {
		buf:=make([]byte,1024)
		for  {
			n,err:=os.Stdin.Read(buf)
			if err!=nil {
				fmt.Print(err)
				continue
			}
			conn.Write(buf[:n])
		}
	}()
	buf:=make([]byte,1024)
	for  {
		n,err:=conn.Read(buf)
		if err==io.EOF {
			continue
		}
		fmt.Print(string(buf[:n]))
	}
