Question

根据附加代码

，您能否请一位来自类测试中 BroadcastServerFactory 的广播功能

我尝试过很多从另一个类调用函数的方法，但没有解决方法

import sys

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()

Answer 1

class test():
  def __init__(self, factory):
    factory.broadcast("I don't know what I'm doing!")

同时，主要......

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

test(factory)

这会做你想要的，但似乎你缺少一些关于类和实例的核心概念。要让test类在另一个类上调用任何东西，首先需要有一个实例（在静态方法的情况下）。

Python，在另一个类中调用类函数
