python - 如何编写一个同时也是客户端的扭曲服务器？

Question

如何创建同时也是客户端的扭曲服务器？我希望 react 堆能够监听，同时它也可以用于连接到同样可以连接和监听的同一个服务器实例。

Answer 1

调用reactor.listenTCP 和reactor.connectTCP。您可以根据需要拥有任意数量的不同类型的连接 - 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()
