Python-Twisted和PyAudio+；聊天

我一直在玩Twisted扩展，还玩过类似聊天室的系统。不过，我想在此基础上进一步阐述。到目前为止，它只支持使用用户名等进行多客户端聊天。但是我想尝试使用pyAudio扩展来构建一种VoIP应用程序。我在客户端有一个clientFactory和一个简单的echo协议，在服务器上有一个serverFactory和协议。但我不完全确定如何在此基础上发展。做这样的事情最好的方法是什么

如果需要，可以编写代码以提供帮助 client.py：

import wx
from twisted.internet import wxreactor
wxreactor.install()

# import twisted reactor
import sys
from twisted.internet import reactor, protocol, task
from twisted.protocols import basic


class ChatFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, parent=None, title="WhiteNOISE")
        self.protocol = None  # twisted Protocol

        sizer = wx.BoxSizer(wx.VERTICAL)
        self.text = wx.TextCtrl(self, style=wx.TE_MULTILINE | wx.TE_READONLY)
        self.ctrl = wx.TextCtrl(self, style=wx.TE_PROCESS_ENTER, size=(300, 25))

        sizer.Add(self.text, 5, wx.EXPAND)
        sizer.Add(self.ctrl, 0, wx.EXPAND)
        self.SetSizer(sizer)
        self.ctrl.Bind(wx.EVT_TEXT_ENTER, self.send)


    def send(self, evt):
        self.protocol.sendLine(str(self.ctrl.GetValue()))
        self.ctrl.SetValue("")


class DataForwardingProtocol(basic.LineReceiver):
    def __init__(self):
        self.output = None

    def dataReceived(self, data):
        gui = self.factory.gui

        gui.protocol = self
        if gui:
            val = gui.text.GetValue()
            gui.text.SetValue(val + data)
            gui.text.SetInsertionPointEnd()

    def connectionMade(self):
        self.output = self.factory.gui.text  # redirect Twisted's output


class ChatFactory(protocol.ClientFactory):
    def __init__(self, gui):
        self.gui = gui
        self.protocol = DataForwardingProtocol

    def clientConnectionLost(self, transport, reason):
        reactor.stop()

    def clientConnectionFailed(self, transport, reason):
        reactor.stop()


if __name__ == '__main__':
    app = wx.App(False)
    frame = ChatFrame()
    frame.Show()
    reactor.registerWxApp(app)
    reactor.connectTCP("192.168.1.115", 5001, ChatFactory(frame))
    reactor.run()

server.py：

from twisted.internet import reactor, protocol

        self.factory.clients.append(self)
        print t() + "+ Connection from: "+ self.transport.getPeer().host

    #on client connection lost
        self.sendMsg("- %s left." % self.name)
        print t() + "- Connection lost: "+ self.name
        self.factory.clients.remove(self)

    def lineReceived(self, line):
    #actions to do on message recive
        if line == '/quit':
    #close client connection
            self.sendLine("Goodbye.")
            self.transport.loseConnection()
            return
        elif line == "/userlist":
    #send user list to single client, the one who requested it
            self.chatters()
            return
    elif line.startswith("/me"):
    #send an action formatted message
        self.sendLine("**" + self.name + ": " + line.replace("/me",""))
        return
    elif line == "/?":
        self.sendLine("Commands: /? /me /userlist /quit")
        return
        if not self.count:
            self.username(line)
        else:
            self.sendMsg(self.name +": " + line)

    def username(self, line):
    #check if username already in use
        for x in self.factory.clients:
            if x.name == line:
                self.sendLine("This username is taken; please choose another")
                return

        self.name = line
        self.chatters()
        self.sendLine("You have been connected!")
        self.sendLine("")

        print '%s~ %s connected as: %s' % (t(), self.transport.getPeer().host, self.name)

    def chatters(self):
        x = len(self.factory.clients) - 1
        s = 'is' if x == 1 else 'are'
        p = 'person' if x == 1 else 'people'
        self.sendLine("There %s %i other %s connected:" % (s, x, p) )

        for client in self.factory.clients:
            if client is not self:
                self.sendLine(client.name)
        self.sendLine("")

    def sendMsg(self, message):
    #send message to all clients
        for client in self.factory.clients:
            client.sendLine(t() + message)


class EchoServerFactory(protocol.ServerFactory):
    protocol  = EchoProtocol
    clients = []

if __name__ == "__main__":
    reactor.listenTCP(5001, EchoServerFactory())
    reactor.run()

看一看，一个SIP应用服务器。基本思想是，您需要在应用程序中添加一个支持应用程序VoIP部分的网络服务器。

谢谢，我理解。谢谢你的帮助链接！
