Python，调用另一个类中的类函数

您能帮我调用类测试中的广播服务器工厂中的广播功能，请参见所附代码

我尝试过很多从另一个类调用函数的方法，但没有解决方案

import sys

from twisted.internet import reactor
from twisted.python import log
from twisted.web.server import Site
from twisted.web.static import File

from autobahn.websocket import WebSocketServerFactory, \
                               WebSocketServerProtocol, \
                               listenWS


class test():
    //call broadcast function from here


class BroadcastServerProtocol(WebSocketServerProtocol):

   def onOpen(self):
      self.factory.register(self)

   def onMessage(self, msg, binary):
      if not binary:
         self.factory.broadcast("'%s' from %s" % (msg, self.peerstr))

   def connectionLost(self, reason):
      WebSocketServerProtocol.connectionLost(self, reason)
      self.factory.unregister(self)


class BroadcastServerFactory(WebSocketServerFactory):
   """
   Simple broadcast server broadcasting any message it receives to all
   currently connected clients.
   """

   def __init__(self, url, debug = False, debugCodePaths = False):
      WebSocketServerFactory.__init__(self, url, debug = debug, debugCodePaths = debugCodePaths)
      self.clients = []
      self.tickcount = 0
      self.tick()

   def tick(self):
      self.tickcount += 1
      self.broadcast("'tick %d' from server" % self.tickcount)
      reactor.callLater(1, self.tick)

   def register(self, client):
      if not client in self.clients:
         print "registered client " + client.peerstr
         self.clients.append(client)

   def unregister(self, client):
      if client in self.clients:
         print "unregistered client " + client.peerstr
         self.clients.remove(client)

   def broadcast(self, msg):
      print "broadcasting message '%s' .." % msg
      for c in self.clients:
         c.sendMessage(msg)
         print "message sent to " + c.peerstr


if __name__ == '__main__':

   if len(sys.argv) > 1 and sys.argv[1] == 'debug':
      log.startLogging(sys.stdout)
      debug = True
   else:
      debug = False

   ServerFactory = BroadcastServerFactory
   #ServerFactory = BroadcastPreparedServerFactory

   factory = ServerFactory("ws://localhost:9000",
                           debug = debug,
                           debugCodePaths = debug)

   factory.protocol = BroadcastServerProtocol
   factory.setProtocolOptions(allowHixie76 = True)
   listenWS(factory)

   webdir = File(".")
   web = Site(webdir)
   reactor.listenTCP(8080, web)

   reactor.run()

同时，大体上

factory = ServerFactory("ws://localhost:9000",
  debug = debug,
  debugCodePaths = debug)

test(factory)

这将实现您想要的功能，但您似乎缺少了有关类和实例的一些核心概念。对于

test

类要调用另一个类上的任何东西，首先需要有它的实例（静态方法除外）。

def\uuuuu init\uuuuuuuuuuuuuuuuuuuuuuuu（工厂）：

应该是

def\uuuuuu init\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu，这将用现有的BroadcastServerFactory作为URL参数实例化一个新的BroadcastServerFactory，很可能会出现异常。你想从测试中调用广播，对吗？这就是它的作用。我想你需要考虑一下你真正想要达到的目标，并把它放在你的问题中。我想做的就是广播另一个班级的信息。
factory = ServerFactory("ws://localhost:9000",
  debug = debug,
  debugCodePaths = debug)

test(factory)
