hello大家好，今天说一下python的socket编程，基于python的socket通信的文本框网络聊天

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：
