简单的paython聊天服务器

利用pythone写的一个简单的聊天服务器，用来进行iOS的socket编程练习，

#!/usr/bin/env python
#-*- coding:utf-8 -*-
import socket,traceback,os
from threading import *

host = '127.0.0.1'
port = 8000     #监听所有的接口

#接受消息的线程
def handlerecv(clientsock):
    print "New child",currentThread().getName()
    print "Got connection from",clientsock.getpeername()
    while True:
        data = clientsock.recv(4096)
        if not len(data):
            break
        print data
    clientsock.close()

#发送消息的线程
def handlesend(clientsock):
    while True:
        data = raw_input(">")
        data = data + "\n";   #加上换行，好看一点。
        clientsock.sendall(data)
    #关闭连接
    clientsock.close()

#建立套接字
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET,socket.SO_REUSEADDR,1)
s.bind((host,port))
s.listen(1)

while True:
    try:
        clientsock,clientaddr = s.accept()
    except KeyboardInterrupt:
        raise
    except:
        traceback.print_exc()
        continue

    t = Thread(target = handlerecv,args=[clientsock])
    t.setDaemon(1)
    t.start()
