我目前正在尝试将基于twisted的应用程序转换为twisted twisted应用程序框架（TAC）。
如果我启动.py，但不使用"twistd-noy-zmq2tcp.tac"守护进程，应用程序就会工作。ZMQ连接似乎已正确打开，但如果使用tac文件启动，则不会在端口2323上侦听。
请解释为什么在这种情况下listenTCP可以工作，但不能在互联网上工作。TCPServer

问题是，在ListenService.startService中，您正在创建并返回TCPServer服务，但您并没有启动该服务。
IService.startService不返回值，所以与其返回return internet.TCPServer(LISTEN_PORT, self.minidoFactory)，不如返回internet.TCPServer(LISTEN_PORT, self.minidoFactory).startService()。
不过，这有一个明显的问题，那就是您的stopService稍后将不记得TCPServer在哪里停止它。最好考虑到这一点，尽快创建TCPServer，并将其与您的服务一起启动/停止，如下所示：
class ListenService(service.Service):
def __init__(self):
self.zf = ZmqFactory()
self.minidoFactory = MinidoServerFactory()
self.tcpService = internet.TCPServer(LISTEN_PORT, self.minidoFactory)
def startService(self):
self.sube = ZmqEndpoint('connect', 'tcp://localhost:5557')
self.push = ZmqEndpoint('connect', 'tcp://localhost:5558')
self.subconn = ZmqSubConnection(self.zf, self.sube)
self.subconn.subscribe('')
# Create the resource
self.minidoFactory.pushconn = ZmqPushConnection(self.zf, self.push)
self.subconn.gotMessage = self.minidoFactory.send2tcp
self.tcpService.startService()
def stopService(self):
del self.sube
del self.push
del self.subconn
return self.tcpService.stopService()
首先，非常感谢您的完美回答。以下是我发现的同样有效的解决方法。但我不完全理解下面的解决方案，更喜欢你的解决方案和解释，所以我会把它标记为the ONE。
