如何编写也是客户端的扭曲服务器？

Question

如何创建也是客户端的扭曲服务器？ 我希望反应器能够监听，同时它也可以用来连接到同样可以连接和监听的服务器实例。

请致电reactor.listenTCP和reactor.connectTCP。只要您愿意，您可以拥有许多不同种类的连接 - 服务器或客户端。

例如：

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()
