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：
