python简单C/S模式示例

服务器端代码：

 1 #!/usr/bin/python
 2 
 3 import time, socket, threading
 4 
 5 # thread handle function
 6 def tcplink(sock, addr):
 7     print 'Accept new connection from %s:%s...' % addr
 8     sock.send('Welcome!')
 9     while True:
10         data = sock.recv(1024)
11         time.sleep(1)
12         if data == 'exit' or not data:
13             break
14         sock.send('Hello, %s!' % data)
15     sock.close()
16     print 'Connection from %s:%s closed.' % addr
17 
18 # create socket object
19 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
20 # listen port
21 s.bind(('127.0.0.1', 9999))
22 # start listen
23 s.listen(5)
24 # print prompt
25 print 'Waiting for connection...'
26 
27 while True:
28     # accept a new connection
29     sock, addr = s.accept()
30     # create new thread to handle tcp connection
31     t = threading.Thread(target=tcplink, args=(sock, addr))
32     t.start()
33 
34

客户端代码：

 1 #!/usr/bin/python
 2 
 3 # import module
 4 import socket
 5 
 6 # create TCP object
 7 s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
 8 # connect sina
 9 s.connect(('127.0.0.1', 9999))
10 # receive welcome
11 print s.recv(1024)
12 
13 for data in ['zjw', 'ygl', 'lele']:
14     # send data
15     s.send(data)
16     print s.recv(1024)
17 while True:
18     data = 1

设计思路还是那样的，服务器端监听固定端口，等待连接，客户端来连接，然后互相发送消息
