Hello大家好，今天说一下python的socket编程，
首先，实验环境：
一个云服务器（我们这里是用的阿里云，大家将就自己的条件吧）；
类Unix操作系统（如Mac OS，Linux等）；
Windows系列操作系统。
在这里，我使用的是阿里云，Mac OSX，Windows XP（在mac上的一个虚拟机）。
Server.py
# -*- coding: utf-8 -*-
#!/usr/local/bin/python
import socket
import sys
import threading
con = threading.Condition()
HOST = "云空间的IP地址"
PORT = 端口
data = ‘‘
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print ‘Socket created‘
s.bind((HOST, PORT))
s.listen(10)
print ‘Socket now listening‘
def clientThreadIn(conn, nick):#开辟线程
global data
while True:#接受客户端数据
try:
temp = conn.recv(1024)
if not temp:
conn.close()#连接关闭
return
NotifyAll(temp)
print data
except:
NotifyAll(nick + " leaves the room!")
print data
return
def NotifyAll(sss):#广播
global data
if con.acquire():
data = sss
con.notifyAll()
con.release()
def ClientThreadOut(conn, nick):#客户端输出
global data
while True:
if con.acquire():
con.wait()
if data:
try:
conn.send(data)
con.release()
except:
con.release()
return
while 1:
conn, addr = s.accept()
print ‘Connected with ‘ + addr[0] + ‘:‘ + str(addr[1])
nick = conn.recv(1024)
NotifyAll(‘Welcome ‘ + nick + ‘ to the room!‘)
print data
print str((threading.activeCount() + 1) / 2) + ‘ person(s)!‘
conn.send(data)
threading.Thread(target = clientThreadIn , args = (conn, nick)).start()#开辟线程
threading.Thread(target = ClientThreadOut , args = (conn, nick)).start()
s.close()
Client.py
# -*- coding: utf-8 -*-
import socket
import threading
import getpass
inString = ‘‘
outString = ‘‘
nick = ‘‘
def DealOut(s):
computername=socket.gethostname()#获取计算机名
global nick, outString
while True:
outString = raw_input(nick+":")
outString = nick + "@" + computername + ‘: ‘ + outString
s.send(outString)
def DealIn(s):
global inString
while True:
try:
inString = s.recv(1024)
if not inString:
break
if outString != inString:
print inString
except:
break
nick = getpass.getuser()#获取操作系统用户名
ip = "云空间IP地址"
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((ip, 端口))
sock.send(nick)
thin = threading.Thread(target = DealIn, args = (sock,))#开辟一个读入的线程
thin.start()
thout = threading.Thread(target = DealOut, args = (sock,))#开辟一个写出的线程
thout.start()
将server.py上传云端，运行，如图：
将client.py在mac系统上运行，如图：
将client.py在WindowsXP虚拟机上运行，如图：
OK，这就可以了，一个基于python的socket通信的文本框网络聊天室就写好了。
