與多個端口，協議和反應器扭曲

Question

扭曲的支持是否會同時監聽多個端口，具有不同的「處理程序」（不同的每個端口的回調集）？實質上，我希望我的進程在一個進程中託管兩臺服務器，每臺服務器執行不同的功能。我需要使用兩個反應器來做到這一點嗎？

Answer 1

是，例如，修改quote server example你可以添加第二個實例監聽不同的端口上使用不同的報價：

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() 

輸出：

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