python - Twisted 具有多个端口、协议(protocol)和 react 器

Question

twisted 是否支持同时使用不同的“处理程序”(每个端口的不同回调集)监听多个端口？本质上，我希望我的进程在一个进程中托管两个服务器，每个服务器执行不同的功能。我是否需要使用两个 react 器来执行此操作？

Answer 1

是的，例如，修改 quote server example您可以添加第二个实例，用不同的引号监听不同的端口:

from twisted.internet.protocol import Factory, Protocol
from twisted.internet.endpoints import TCP4ServerEndpoint
from twisted.internet import reactor

class QOTD(Protocol):

    def connectionMade(self):
        # self.factory was set by the factory's default buildProtocol:
        self.transport.write(self.factory.quote + '\r\n')
        self.transport.loseConnection()


class QOTDFactory(Factory):

    # This will be used by the default buildProtocol to create new protocols:
    protocol = QOTD

    def __init__(self, quote=None):
        self.quote = quote or 'An apple a day keeps the doctor away'

endpoint = TCP4ServerEndpoint(reactor, 8007)
endpoint.listen(QOTDFactory("configurable quote"))

endpoint2 = TCP4ServerEndpoint(reactor, 8008)
endpoint2.listen(QOTDFactory("another configurable quote"))

reactor.run()

输出:

$ nc localhost 8007
configurable quote
$ nc localhost 8008
another configurable quote
