Twisted - 将数据发送到选定的客户端

我用 Twisted 创建了一个服务器，它从客户端接收字符串并将其发送到所有其他连接的客户端。 但是有没有办法将字符串发送到发送者想要发送到的客户端？如果是这样，我该如何在代码中做到这一点？这就是我到目前为止所做的（注意，我是一个 Python 菜鸟。我只需要为我的 iOS 应用程序构建一个服务器，所以如果问题很愚蠢，我很抱歉）：

from twisted.internet.protocol import Protocol, Factory
from twisted.internet import reactor


class IphoneChat(Protocol):
    def connectionMade(self):
        #self.transport.write("""connected""")
        self.factory.clients.append(self)
        print "clients are ", self.factory.clients

    def connectionLost(self, reason):
        self.factory.clients.remove(self)

    def dataReceived(self, data):
        #print "data is ", data
        a = data.split(':')
        if len(a) > 1:
            command = a[0]
            content = a[1]

            msg = ""
            if command == "iam":
                self.name = content
                msg = "iam" + self.name + " has joined"

            elif command == "msg":
                msg = self.name + ": " + content

            elif command == "img":
                msg = command + ":" + content + ":" + command

            elif command == "img2":
                msg = content

            elif command == "img3":
                msg = content

            print msg

            for c in self.factory.clients:
                c.message(msg)

    def message(self, message):
        self.transport.write(message + '\n')


factory = Factory()
factory.protocol = IphoneChat
factory.clients = []

reactor.listenTCP(53080, factory)
print "Iphone Chat server started"
reactor.run()

谢谢您的帮助

self.factory.clients[24].transport.write("You are client 24!")

我认为应该有效
