skcket编程实例

 

socket编程服务端编码如下：

#!/usr/bin/env python

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 'waitig 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))
                print [ctime()],':',data
tcpCliSock.close()
tcpSerSock.close()

 

 

socket客户端代码：

#!/usr/bin/env python

from socket import *

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

tcpCliSock=socket(AF_INET,SOCK_STREAM)
print 1
tcpCliSock.connect(ADDR)
print 2
while True:
        data=raw_input('>')
        if not data:
                break
        tcpCliSock.send(data)
        data=tcpCliSock.recv(BUFSIZ)
        if not data:
                break
        print data
tcpCliSock.close()

 

服务端启动：

[nanjing3@master python]$ ./tsTserv.py 
waitig for connection...

客户端启动并输入信息：

　

[nanjing3@master python]$ ./tscli.py 
1
2
>1
[Wed Nov  7 02:29:25 2012] 1
>2
[Wed Nov  7 02:29:34 2012] 2
>hi
[Wed Nov  7 02:29:39 2012] hi
>how are you!
[Wed Nov  7 02:29:47 2012] how are you!

 

服务端接收到信息：

[nanjing3@master python]$ ./tsTserv.py 
waitig for connection...
...connected from: ('127.0.0.1', 51800)
['Wed Nov  7 02:29:25 2012'] : 1
['Wed Nov  7 02:29:34 2012'] : 2
['Wed Nov  7 02:29:39 2012'] : hi
['Wed Nov  7 02:29:47 2012'] : how are you!

 端口占用情况：

[root@master ~]# netstat |grep 21567
