扭曲了多个端口，协议和反应器

问题描述

扭曲的支持是否会同时在多个端口上监听不同的处理程序"(每个端口的回调集不同)?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.我需要使用两个反应堆吗?

Will twisted support listening on multiple ports, with different 'handlers' (different set of callbacks for each port) at the same time? Essentially, I want my process to host two servers in one process, each performing a different function. Would I need to use two reactors to do this?

推荐答案

是的，例如，修改引用服务器示例，您可以添加第二个实例，该实例在另一个端口上监听不同的报价:

Yes, for instance, modifying the quote server example you could add a second instance listening on a different port with a different quote:

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
