[英]Python, Call a class function within another class
Can you anyone please help me call the broadcast function from class BroadcastServerFactory in class test , as per attached code 你有没有人可以帮助我在类测试中调用BroadcastServerFactory 类中的广播函数 ,如附加代码所示
I have tried so many methods of call a function from another class, but no solution 我尝试了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()
class test():
def __init__(self, factory):
factory.broadcast("I don't know what I'm doing!")
Meanwhile, in main... 同时,主要...
factory = ServerFactory("ws://localhost:9000",
debug = debug,
debugCodePaths = debug)
test(factory)
This will do what you want, but it seems you're missing some core concepts about classes and instances . 这将做你想要的,但似乎你缺少一些关于类和实例的核心概念。 For the test
class to call anything on another class, there needs to be an instance of it first (bar the case of static methods). 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(例如静态方法)。
