服务器/客户端通信问题

[wokaoyan1981]

这是《python核心编程（第3版）》第二章的示例。任务是：服务器接受客户端发送的数据字符串，并将其打上时间戳并返回给客户端。
遗憾的是，先运行服务器端代码，再运行客户端代码，并没有得到任何结果！请问如何解决？
服务器端代码tsTserv3.py:

#!/usr/bin/env python

from socket import *
from time import ctime
HOST = ''
PORT = 21565
BUFSIZ = 1024
ADDR = (HOST, PORT)

tcpSerSock = socket(AF_INET, SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)

while True:
    print('waiting for connection...')
    tcpCliSock, addr = tcpSerSock.accept()
    print('...connected from:', addr)

    while True:
        data = tcpCliSock.recv(BUFSIZ)
        if not data:
            break
        tcpCliSock.send('[%s] %s' % (
            bytes(ctime(), 'utf-8'), data))
        tcpCliSock.close()
    tcpSerSock.close()

客户端代码tsTcint3.py:

#!/usr/bin/env python

from socket import *

HOST = '127.0.0.1'
PORT = 21565
BUFSIZ = 1024
ADDR = (HOST, PORT)

tcpCliSock = socket(AF_INET, SOCK_STREAM)
tcpCliSock.connect(ADDR)

while True:
    data = input('> ').encode()
    if not data:
        break
    tcpCliSock.send(data)
    data = tcpCliSock.recv(BUFSIZ)
    if not data:
        break
    print(data.decode('utf-8'))

tcpCliSock.close()

你把服务端回消息改成下面这样，客户端输入后可以得到回复的

#!/usr/bin/env python

from socket import *
from time import ctime
HOST = ''
PORT = 21565
BUFSIZ = 1024
ADDR = (HOST, PORT)

tcpSerSock = socket(AF_INET, SOCK_STREAM)
tcpSerSock.bind(ADDR)
tcpSerSock.listen(5)

while True:
    print('waiting for connection...')
    tcpCliSock, addr = tcpSerSock.accept()
    print('...connected from:', addr)

    while True:
        data = tcpCliSock.recv(BUFSIZ)
        if not data:
            break
        tcpCliSock.send(bytes('[%s] %s' % (ctime(), data), 'utf-8'))
    tcpSerSock.close()

谢谢，还有一种方式.encode()
