如果输入quit则关闭连接，通过下面语句

self.transport.loseConnection()

protocol不保存永久数据，每个连接初始化生成protocol实例，连接关闭时退出。而永久数据由factory负责

^C[myhaspl@iZ23mdqdp94Z ~]$ cat  learn/l1/myserver.pl
from twisted.internet.protocol import Protocol
from twisted.internet import reactor
from twisted.internet.protocol import Factory
from twisted.internet.endpoints import TCP4ServerEndpoint

class Echo(Protocol):
    
     def dataReceived(self,data):
         if data!="quit":
              self.transport.write(data)
         else:
              self.transport.loseConnection()

class EchoFactory(Factory):
     def buildProtocol(self,addr):
          return Echo()    

endpoint=TCP4ServerEndpoint(reactor,8001)
endpoint.listen(EchoFactory())
reactor.run()
