python网络socket编程

一、服务端

#!/usr/bin/python
# -*- coding: UTF-8 -*-


import socket
import sys
from thread import *
 
HOST = '127.0.0.1'   # Symbolic name meaning all available interfaces
PORT = 8888 # Arbitrary non-privileged port
 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print 'Socket created'
 
#Bind socket to local host and port
try:
    s.bind((HOST, PORT))
except socket.error , msg:
    print 'Bind failed. Error Code : ' + str(msg[0]) + ' Message ' + msg[1]
    sys.exit()
     
print 'Socket bind complete'
 
#Start listening on socket
s.listen(10)
print 'Socket now listening'
 
#Function for handling connections. This will be used to create threads
def clientthread(conn):
    #Sending message to connected client
    conn.send('Welcome to the server. Type something and hit enter
') #send only takes string
     
    #infinite loop so that function do not terminate and thread do not end.
    while True:
         
        #Receiving from client
        data = conn.recv(1024)
        reply = '收到信息：' + data

        print reply

        reply = "my name is 徐芳波 " 
        if not data: 
            break
     
        conn.sendall(reply)
     
    #came out of loop
    conn.close()
 
#now keep talking with the client
while 1:
    #wait to accept a connection - blocking call
    conn, addr = s.accept()
    print 'Connected with ' + addr[0] + ':' + str(addr[1])
     
    #start new thread takes 1st argument as a function name to be run, second is the tuple of arguments to the function.
    start_new_thread(clientthread ,(conn,))
 
s.close()

二、客户端

#!/usr/bin/python
# -*- coding: UTF-8 -*-
# 文件名：client.py


import socket               # 导入 socket 模块
import time

s = socket.socket()         # 创建 socket 对象
host = '127.0.0.1' # 获取本地主机名
port = 8888                # 设置端口好

s.connect((host, port))

while True :

    s.send("my name is 开心 " )
    data = s.recv(1024)
    print '收到信息：'+data
    time.sleep(1)

s.close()

三、运行服务端

root@xushi:~/ai/python# python netsharp.pigeon.py
Socket created
Socket bind complete
Socket now listening
Connected with 127.0.0.1:40114
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心 
收到信息：my name is 开心

四、运行客户端

root@xushi:~/ai/python# python netsharp.pigeon.client.py 
收到信息：Welcome to the server. Type something and hit enter

收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波 
收到信息：my name is 徐芳波
