关于twisted 框架中的疑问

from twisted.internet.protocol import Factory
from twisted.protocols.basic import LineOnlyReceiver
from twisted.internet import reactor

class Chat(LineOnlyReceiver):
    def lineReceived(self,data):
        self.factory.sendAll("%s :%s" % (self.getId(), data))

    def getId(self):
        return str(self.transport.getPeer())

    def connectionMade(self):
        print "New commectioin from",self.getId()
        self.transport.write("Welcome to the chat server , %s\n" % self.getId())
        self.factory.addClient(self)

    def connectionLost(self,reason):
        self.factory.delClient(self)

class ChatFactory(Factory):
    protocol = Chat

    def __init__(self):
        self.clients = []

    def addClient(self,newclient):
        self.clients.append(newclient)

    def delClient(self, message):
        for proto in self.clients:
            proto.transport.write(message + "\n")

reactor.listenTCP(5000, ChatFactory())
reactor.run()

以上代码用为服务端运行后为什么sendAll不能正常工作，总是报错，或者哪位能帮我编个跟他配套的client

你需要为ChatFactory实现sendAll方法

已经解决;
但是还是有很疑问，比如服务端client是什么东东?信息的最大尺度?另外最重要是dataReceived与lineReceived的区别，因为我是客户端是用flex做的，现在对dataReceived支持很好，要如何才能支持lineReceived呢?希望有高人指点

没用过。

谢谢各位回贴,特别是shhgs .

多问一句,关于在twisted如果想客户端调服务端的方法,或是服务端调用客户端要如何操作呢.或是不走twisted这条路了.
