与多个端口，协议和反应器扭曲

Question

扭曲的支持是否会同时监听多个端口，具有不同的“处理程序”（不同的每个端口的回调集）？实质上，我希望我的进程在一个进程中托管两台服务器，每台服务器执行不同的功能。我需要使用两个反应器来做到这一点吗？

Answer 1

是，例如，修改quote server example你可以添加第二个实例监听不同的端口上使用不同的报价：

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
