POtwisted web getPage, 2 clients in 2 classes, manage events between the two

Body
copied!<p>i'm trying to create a bridge program in twisted.web that receives data from a web server and sends it to another server, thus i'm using 2 getPage applications that i have wrapped in a class for convenience, the class contains all the callbacks and the client "routine".. 1)auth 2)receive data 3)send data, all this is done in a cyclic way and works perfectly in both clients!!</p> <p>What i am planning to do now is to integrate the two, this would mean that i would have to make some callbacks outside the classes in order to process them.</p> <p>client1<--->main<--->client2</p> <p>How can i do this?</p> <p>i'm using twisted getPage</p> <p>i'll post one of the two classes</p> <pre><code>class ChatService(): def __init__(self): self.myServID= self.generatemyServID() self.myServServer= "http://localhost" ## This is where the magic starts reactor.callWhenRunning(self.mainmyServ) reactor.run() def generatemyServID(self): a= "" for x in range(60): c= floor(random() * 61) a += "0123456789ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz"[int(c):int(c)+1] return a def sentMessage(self, data): print "Message was sent successfully" def sendMessage(self, mess): s1= DeferredList([client.getPage(self.myServServer+"/chat/", headers={'Content-Type': 'application/x-www-form-urlencoded'}, method="POST", postdata="action=chat&user=%s&message=%s" % (self.myServID, mess)),]) s1.addCallback(self.sentMessage) s1.addErrback(self.errMessage) def recivedMessage(self,data): chat= loads(data[0][1]) if chat['from'] != "JOINED" and chat['from'] != "TYPING" and chat['from'] != "Ben": print "%s says: %s" % (chat['from'], decode(chat['chat'])) self.sendMessage("Hello") # Restart Loop self.loopChat() def errMessage(self,e): # print "An error occured receiving/sending the messages\n%s" % e print "Still no connectiions, waiting..." self.loopChat() def loopChat(self): s1= DeferredList([client.getPage(self.myServServer+"/chat/", headers={'Content-Type': 'application/x-www-form-urlencoded'}, method="POST", postdata="action=poll&user=%s&message=null" % self.myServID),]) s1.addCallback(self.recivedMessage) s1.addErrback(self.errMessage) def error(self,e): print "An error occured\n%s" % e def connectedtomyServService(self,data): if data[0][0] == False: print "Connection to myServ Service was impossible" reactor.stop() return if loads(data[0][1])['action'] == 'join': print "Connected to the server and joined chat" print "Started chat loop" self.loopChat() else: print "An Error Occured" return def mainmyServ(self): # print "Client ID is: " + self.myServID # Joining Chat s1= DeferredList([client.getPage(self.myServServer+"/chat/", headers={'Content-Type': 'application/x-www-form-urlencoded'}, method="POST", postdata="action=join&user=%s&message=null" % self.myServID),]) s1.addCallback(self.connectedtomyServService) s1.addErrback(self.error) </code></pre> <p>How can I make callbacks outside the class?</p> <p>I hope I managed to express myself =D</p> <p>Thnaks a lot</p>
