Question

下面两段代码的任务是从Client接收一个字符串，然后加上时间戳，最后发送回Client。我以正确的顺序运行它们（首先是服务器，然后是客户端），但是在输入字符串后似乎没有任何反应。这是我的代码：

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()

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()

当我更改服务器中的代码时，这很有效：

tcpCliSock.send(f'{ctime()} {data}'.encode())

并在最后两行中删除一次制表符空间。

所以服务器的最终代码将是这样的：

#!/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(f'{ctime()} {data}'.encode())
    tcpCliSock.close()
tcpSerSock.close()

服务器与客户端通信失败
