蟒蛇3.3套接字TypeError

Question

我想制作一个时间戳服务器和客户端。客户端代码是：

from socket import * 

HOST = '127.0.0.1' # or 'localhost' 
PORT = 21567 
BUFSIZ = 1024 
ADDR = (HOST, PORT) 

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

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

tcpCliSock.close() 

和服务器的代码是：

from socket import * 
from time import ctime 

HOST = '' 
PORT = 21567 
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() 

服务器工作正常，但是当我发送任何数据从客户端我收到以下错误服务器：

File "tsTclnt.py", line 20, in <module> 
    tcpCliSock.send(data) 
TypeError: 'str' does not support the buffer interface

您需要使用适当的代码页将data中的字符串编码到缓冲区。例如：

data = input('> ') 
if not data: 
    break 
tcpCliSock.send(data.encode('utf-8')) 

服务器代码需要改变过：

response = '[%s] %s' % (ctime(), data.decode('utf-8')) 
tcpCliSock.send(response.encode('utf-8'))
