How do I create a twisted server that's also a client? I want the reactor to listen while at the same time it can also be use to connect to the same server instance which can also connect and listen.
Call reactor.listenTCP
and reactor.connectTCP
. You can have as many different kinds of connections - servers or clients - as you want.
For example:
from twisted.internet import protocol, reactor
from twisted.protocols import basic
class SomeServerProtocol(basic.LineReceiver):
def lineReceived(self, line):
host, port = line.split()
port = int(port)
factory = protocol.ClientFactory()
factory.protocol = SomeClientProtocol
reactor.connectTCP(host, port, factory)
class SomeClientProtocol(basic.LineReceiver):
def connectionMade(self):
self.sendLine("Hello!")
self.transport.loseConnection()
def main():
import sys
from twisted.python import log
log.startLogging(sys.stdout)
factory = protocol.ServerFactory()
factory.protocol = SomeServerProtocol
reactor.listenTCP(12345, factory)
reactor.run()
if __name__ == '__main__':
main()
