Python socket实现简单聊天室

本文实例为大家分享了Python socket实现简单聊天室的具体代码，供大家参考，具体内容如下

服务端使用了select模块，实现了对多个socket的监控。客户端由于select在Windows下只能对socket使用，所以使用了多线程来实现对客户端输入和socket连接的同时监控。注意这里的socket设置为了非阻塞。这样就实现了在一个线程中同时进行socket的接收和发送。

服务器代码：

# -*- coding: utf-8 -*-
import socket,select

connection_list = []
host = ''
port = 10001

def board_cast(sock,message):
for socket in connection_list:
 if socket != server_sock and socket != sock:
  try:
   socket.send(message)
  except:
   socket.close()
   print str(socket.getpeername())+' is offline'
   connection_list.remove(socket)

server_sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
server_sock.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
server_sock.setblocking(0)
server_sock.bind((host,port))
server_sock.listen(10)
connection_list.append(server_sock)

while 1:
readable,writable,error = select.select(connection_list,[],[])
for sock in readable:
 if sock == server_sock:
  connection,connection_add = sock.accept()
  message = str(connection_add)+'enter room'
  board_cast(connection,message)
  print connection_add,'％s connect'
  connection_list.append(connection)
 else:
  try:
   date = sock.recv(1024)
   print date
   board_cast(sock,'('+str(sock.getpeername())+') :'+date)
  except:
   message2 = str(sock.getpeername())+ 'is offline'
   board_cast(sock,message2)
   print str(sock.getpeername())+ ' is offline'
   sock.close()
   connection_list.remove(sock)
   continue

客户端代码：

# -*- coding: utf-8 -*-
import socket,threading,time
flag = 0
date = ''
lock = threading.Lock()

host = 'localhost'
port = 10001
client_sock = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
client_sock.setblocking(0)

class Mythread1(threading.Thread):
def __init__(self):
 threading.Thread.__init__(self)
def run(self):
 global flag, date
 while 1:
  date = raw_input()
  if len(date):
   lock.acquire()
   flag = 1
   lock.release()

class Mythread2(threading.Thread):
def __init__(self):
 threading.Thread.__init__(self)
def run(self):
 global flag
 global date
 while 1:
  try:
   buf = client_sock.recv(1024)
   if len(buf):
    print buf
  except:
   pass
  if flag:
   try:
    client_sock.send(date)
   except socket.error, e:
    print e
   lock.acquire()
   flag = 0
   lock.release()

try:
client_sock.connect((host,port))
print"连接成功"
except socket.error,e:
print e

t1 = Mythread1()
t2 = Mythread2()
t1.start()
t2.start()
