Python实现的非阻塞长连接tcpserver服务器端【epoll版】

利用epoll实现的非阻塞服务器端代码

这不是一个完整实例, 只是一个参考, 偶没有测试过！

#!/usr/bin/env python# -*-coding:UTF-8-*-import select,socket,time# select.epoll()必须在版本高于py2.6以上使用server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)server.bind(("192.168.1.174", 2222))server.listen(1)server.setblocking(0)epoller = select.epoll()epoller.register(server.fileno(), select.POLLIN|select.POLLERR|select.POLLHUP)print "Server Started!\n"while True:    ret = epoller.poll()    if ret==None:        continue    try:        if ret[0][1] == select.POLLIN:            clientSock,clientAddr = server.accept()            print "[",clientAddr,"] Connectioned!\n"            _data = '';            while True:                _tmp = clientSock.recv(1)                if _tmp == 0:                    continue                _data +=_tmp                if _tmp == "\n":#如接收到换行分割符则分析已接收到的字符串做出相应处理并反馈给客户端                    if _data[:len(_data-1)] == 'help':                        clientSock.send(" Thank your! Your said:" + _data)                        _data = ''                        continue                    elif _data == 'xiexie':                        clientSock.send(" Thank your!
