本文例項講述了python實現TCP伺服器端與客戶端的方法。分享給大家供大家參考。具體如下:

TCP伺服器程式(tsTserv.py):


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' %(ctime(), data))
tcpCliSock.close()
tcpSerSock.close()

TCP客戶端程式(tsTclnt.py):


from socket import *
HOST = 'localhost'
PORT = 21567
BUFSIZ = 1024
ADDR = (HOST, PORT)
tcpCliSock = socket(AF_INET, SOCK_STREAM)
tcpCliSock.connect(ADDR)
while True:
data = raw_input('> ')
if not data:
break
tcpCliSock.send(data)
data1 = tcpCliSock.recv(BUFSIZ)
if not data1:
break
print data1
tcpCliSock.close()

執行說明:先執行伺服器程式,作用類似於開啟伺服器保持等待客戶請求,再執行客戶端程式。

執行介面如下:

伺服器端:


D:\code\ex>python tsTserv.py
waiting for connection...
...connected from: ('127.0.0.1', 2883)
waiting for connection...
...connected from: ('127.0.0.1', 2885)
waiting for connection...
...connected from: ('127.0.0.1', 2889)
waiting for connection...
...connected from: ('127.0.0.1', 2891)
waiting for connection...
...connected from: ('127.0.0.1', 2892)
waiting for connection...
...connected from: ('127.0.0.1', 2893)
waiting for connection...

客戶端:


D:\code\ex>python tsTclnt.py

希望本文所述對大家的Python程式設計有所幫助。
