Hi, I've written a simple twisted server, which accepts client connections, and respond with some simple text depending on what the client sends. This is working fine if I use telnet to connect to the server, and enter the commands one at a time. I'd like to write a twisted client to simulate this, i.e., the client has a list of commands to send, it will send one at a time, (may be wait a little bit between the commands,) and print out the responses from the server. I couldn't seem to get beyond the first command, following code seems to send all the commands at the end, rather than one at a time, how can I add sleep in between? Thanks: from twisted.internet.protocol import ReconnectingClientFactory from twisted.protocols import basic from twisted.internet import reactor from sys import stdout import time class MyClientProtocol(basic.LineReceiver): def lineReceived(self,data): stdout.write("Server:" + data+"\n"), def connectionMade(self): stdout.write("connectionMade\n") self.transport.write("start:\r\n") self.transport.write("command1:\r\n") self.transport.write("command2:\r\n") self.transport.write("command3:\r\n") self.transport.write("end:\r\n") class MyClientFactory(ReconnectingClientFactory): def startedConnecting(self, connector): stdout.write("Started to connect\n") def buildProtocol(self,addr): stdout.write("Connected\nResetting reconnection delay") self.resetDelay() return MyClientProtocol() def clientConnectionLost(self, connector, reason): stdout.write("Lost connection, reason:" + reason) ReconnectingClientFactory.clientConnectionList(self, connector, reason) def clientConnectionFailed(self, connector,reason): stdout.write("Connection failed, reason:" + reason) ReconnectingClientFactory.clientConnectionFailed(self, connector, reason) def main(): reactor.connectTCP("localhost",82828, MyClientFactory()) reactor.run() if __name__ == '__main__': main()
