Nothing mind blowing here. I’m playing with Python’s twisted engine, and here is a slightly modified server from their home page example:
from twisted.internet import protocol, reactor class Echo(protocol.Protocol): def dataReceived(self, data): newdata = 'reversed: ' + ''.join(reversed(data.strip())) + 'n' self.transport.write(newdata) class EchoFactory(protocol.Factory): #build an Echo object for each connection def buildProtocol(self, addr): return Echo() reactor.listenTCP(8000, EchoFactory()) #register a callback reactor.run()
Run the script and telnet to port 8000 of this box. This is what it looks like:
Connected to erdos. Escape character is '^]'. hello reversed: olleh reverse this! reversed: !siht esrever
The example is also here, with a more detailed explanation of the basics.
The API reference helps to see what methods need to be implemented while sub-classing one of its classes.
