扭曲多个端口,协议和反应器

是否会支持在多个端口上侦听,同时具有不同的“处理程序”(每个端口的不同回调集)?本质上,我希望我的进程在一个进程中托管两个服务器,每个进程执行不同的功能。我需要使用两个反应器才能做到这一点吗?

是的,例如,修改quote server example您可以添加第二个实例,使用不同的引用在另一个端口上进行侦听:

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
