thanks jean-Pul.i can use commandline to intercat with server by the
it's so easy with it

and there is a sample in Twisted NetWork Programming Essentials


from twisted.internet import stdio, reactor, protocol
from twisted.protocols import basic
import re

class DataForwardingProtocol(protocol.Protocol):
    def _ _init_ _(self):
        self.output = None
        self.normalizeNewlines = False

    def dataReceived(self, data):
        if self.normalizeNewlines:
            data = re.sub(r"(\r\n|\n)", "\r\n", data)
        if self.output:

class StdioProxyProtocol(DataForwardingProtocol):
    def connectionMade(self):
        inputForwarder = DataForwardingProtocol( )
        inputForwarder.output = self.transport
        inputForwarder.normalizeNewlines = True
        stdioWrapper = stdio.StandardIO(inputForwarder)
        self.output = stdioWrapper
        print "Connected to server.  Press ctrl-C to close connection."

class StdioProxyFactory(protocol.ClientFactory):
    protocol = StdioProxyProtocol

    def clientConnectionLost(self, transport, reason):
        reactor.stop( )

    def clientConnectionFailed(self, transport, reason):
        print reason.getErrorMessage( )
        reactor.stop( )

if __name__ == '_ _main_ _':
    import sys
    if not len(sys.argv) == 3:
        print "Usage: %s host port" % _ _file_ _

    reactor.connectTCP(sys.argv[1], int(sys.argv[2]), StdioProxyFactory( ))

    reactor.run( )
