? ? python的twisted比較有意思，既可以做server方面的編程，也可以做client方面的編程。關于這方面的編程，最簡單的例子就是echo。

PYTHON編程？

? ? client 代碼如下，

#!/usr/bin/pythonfrom twisted.internet.protocol import Protocol, ClientFactory
from sys import stdout
from twisted.internet import reactorclass Echo(Protocol):def dataReceived(self, data):stdout.write(data)class EchoClientFactory(ClientFactory):def startedConnecting(self, connector):print 'Started to connect.'def buildProtocol(self, addr):print 'Connected.'return Echo()def clientConnectionLost(self, connector, reason):print 'Lost connection. Reason:', reasondef clientConnectionFailed(self, connector, reason):print 'Connection failed. Reason:', reasonif __name__ == '__main__':reactor.connectTCP('localhost', 1234, EchoClientFactory())reactor.run()

? ? server?代碼如下，

Python編譯？

#!/usr/bin/pythonfrom twisted.internet import protocol, reactor, endpointsclass Echo(protocol.Protocol):def dataReceived(self, data):self.transport.write(data)class EchoFactory(protocol.Factory):def buildProtocol(self, addr):return Echo()if __name__ == '__main__':endpoints.serverFromString(reactor, "tcp:1234").listen(EchoFactory())reactor.run()
