Python扭曲了停止具有多个客户端的Reactor [英] Python Twisted Stopping The Reactor With Multiple Clients

问题描述

如果我通过这样做创建了多个客户：

If I create multiple clients by doing this:

def main():
    clients = [None]*10

    for i in range(0, 10):
        clients[i] = ClientFactory()
        reactor.connectTCP('192.168.0.1', 8000, clients[i])

    reactor.run()

如何-优雅地-停止反应堆？如果我这样做：

How to I -gracefully- stop the reactor? If I do:

self.transport.loseconnection()

在协议中，然后执行以下操作：

In the protocol, then do:

reactor.stop()

在工厂中，下一位客户将试图再次停止反应堆。但是，这当然会导致错误：

In the factory, then the next client is going to try to come along a stop the reactor again. However, this of course leads to the error:

Can't stop a reactor that isn't running

在这种情况下如何优雅地停止反应堆？

How can I gracefully stop the reactor in such a scenario?

推荐答案

从您的协议实现中删除反应堆管理代码。将其替换为一些事件通知代码，您可以使用它们来了解连接何时已完成其需要做的所有事情。例如，发射 Deferred 。

Take your reactor-management code out of your protocol implementation. Replace it with some event-notification code that you can use to learn when the connection has done everything it needs to do. For example, fire a Deferred.

然后等待所有延期并在所有延期时停止反应堆完成。您可能会发现 gatherResults 对此很有帮助。

Then wait on all the deferreds and stop the reactor when they're all done. You might find gatherResults helpful for this.
