- 2. Do Nothing from twisted.internet import reactor reactor.run()
- 3. Protocol Parsing from twisted.internet import reactor, protocol class Echo(protocol.Protocol): def dataReceived(self, data): self.transport.write(data) factory = protocol.Factory() factory.protocol = Echo reactor.listenTCP(1033, factory) reactor.run()
- 4. Web Development from twisted.internet import reactor from twisted.web import resource, server class Resource(resource.Resource): isLeaf = True users = 0 def render_GET(self, request): self.users += 1 return "Welcome user number %d" % self.users reactor.listenTCP(1080, server.Site(Resource())) reactor.run()
- 5. Multi-protocol Servers (Classes) from twisted.internet import reactor, protocol from twisted.web import resource, server class Counter(object): count = 0 def add(self, number): self.count += number class ByteCount(protocol.Protocol): def dataReceived(self, data): self.factory.counter.add(len(data)) class Resource(resource.Resource): isLeaf = True counter = None def render_GET(self, request): return "Received %d bytes" % self.counter.count
- 6. Multi-protocol Servers (Set-up) factory = protocol.Factory() factory.protocol = ByteCount factory.counter = Counter() resource = Resource() resource.counter = factory.counter reactor.listenTCP(1033, factory) reactor.listenTCP(1080, server.Site(resource)) reactor.run()
