This is my server code.......
from twisted.internet import reactor, protocol
class Echo(protocol.Protocol):
"""This is just about the simplest possible
protocol"""
def dataReceived(self, data):
if data == 1:
print data
def connectionMade(self):
print "Client Connected to server"
def main():
"""This runs the protocol on port 8000"""
factory = protocol.ServerFactory()
factory.protocol = Echo
reactor.listenTCP(8000,factory)
reactor.run()
# this only runs if the module was *not* imported
if __name__ == '__main__':
main()
And here is my client code.....
from twisted.internet import reactor, protocol
class EchoClient(protocol.Protocol):
"""Once connected, send a message, then print the
result."""
def connectionMade(self):
buildInfo = 1
self.transport.write(buildInfo)
def dataReceived(self, data):
"As soon as any data is received, write it back."
print "Server said:", data
self.transport.loseConnection()
def connectionLost(self, reason):
print "connection lost"
class EchoFactory(protocol.ClientFactory):
protocol = EchoClient
build = 1
def clientConnectionFailed(self, connector, reason):
print "Connection failed - goodbye!"
reactor.stop()
def clientConnectionLost(self, connector, reason):
print "Connection lost - goodbye!"
reactor.stop()
# this connects the protocol to a server runing on
port 8000
def main():
f = EchoFactory()
reactor.connectTCP("localhost", 8000, f)
reactor.run()
# this only runs if the module was *not* imported
if __name__ == '__main__':
main()
In this test im trying to send some data when the
client makes it's connection, but I get and error when
running the client.
>From all the examples i can find using write method
are all echo/chat programs and from that I guess only
strings/text can be send via the write method.
> Are you familiar with buildbot?
Heard of but never looked at.
I'm very new to this Twisted, and quite new to python.
