python开发----twisted使用例子

服务端：

#!/usr/bin/env python

from twisted.internet import protocol, reactor
from time import ctime

PORT = 21567


class TSServProtocol(protocol.Protocol):
    def connectionMade(self):
        clnt = self.clnt = self.transport.getPeer().host
        print '...conneting from:', clnt

    def dataReceived(self, data):
        self.transport.write('[%s] %s' % (ctime(), data))

factory = protocol.Factory()
factory.protocol = TSServProtocol
print 'waiting for connecting...'
reactor.listenTCP(PORT, factory)
reactor.run()

 

客户端：

#!/usr/bin/env python

from twisted.internet import protocol, reactor

HOST = 'localhost'
PORT = 21567

class TSClntProtocol(protocol.Protocol):
    def sendData(self):
        data = raw_input('> ')
        if data:
            print '...sending %s...' % data
            self.transport.write(data)
        else:
            self.transport.loseConnection()

    def connectionMade(self):
        self.sendData()

    def dataReceived(self, data):
        print data
        self.sendData()

class TSClntFactory(protocol.ClientFactory):
    protocol = TSClntProtocol
    clientConnectionLost = clientConnectionFailed = lambda self, connector, reason: reactor.stop()

reactor.connectTCP(HOST, PORT, TSClntFactory())
reactor.run()
