twisted

问题 I am attempting to make use of the Twisted.Web framework. Notice the three line comments (#line1, #line2, #line3). I want to create a proxy (gateway?) that will forward a request to one of two servers depending on the url. If I uncomment either comment 1 or 2 (and comment the rest), the request is proxied to the correct server. However, of course, it does not pick the server based on the URL. from twisted.internet import reactor from twisted.web import proxy, server from twisted.web.resource

问题 I have a twisted ReconnectingClientFactory and i can successfully connect to given ip and port couple with this factory. And it works well. reactor.connectTCP(ip, port, myHandsomeReconnectingClientFactory) In this situation, when the server is gone, myHandsomeReconnectingClientFactory tries to connect same ip and port (as expected). My goal is, when the server which serves on given ip and port couple is gone, connecting to a backup server (which have different ip and port). Any ideas/comments

问题 I am following the basic wamp pubsub examples in the github code: This example publishes messages from within the class: class Component(ApplicationSession): """ An application component that publishes an event every second. """ def __init__(self, realm = "realm1"): ApplicationSession.__init__(self) self._realm = realm def onConnect(self): self.join(self._realm) @inlineCallbacks def onJoin(self, details): counter = 0 while True: self.publish('com.myapp.topic1', counter) counter += 1 yield

问题 During the scraping process using scrapy one error appears in my logs from time to time. It doesnt seem to be anywhere in my code, and looks like it something inside twisted\openssl. Any ideas what caused this and how to get rid of it? Stacktrace here: [Launcher,27487/stderr] Error during info_callback Traceback (most recent call last): File "/opt/webapps/link_crawler/lib/python2.7/site-packages/twisted/protocols/tls.py", line 415, in dataReceived self._write(bytes) File "/opt/webapps/link

问题 I installed python 2.7.5 which is working fine. I then install scrapy (which, I think, uses twisted internally). My scrapy spider is also working fine. I installed twisted: sudo apt-get install python-twisted Then, I created a sample program using Echo Server code shown here Here is the code from twisted.internet import protocol, reactor class Echo(protocol.Protocol): def dataReceived(self, data): self.transport.write(data) class EchoFactory(protocol.Factory): def buildProtocol(self, addr):

问题 I need help understanding what the advantage of using an asynch framework is. Suppose I want to develop a simple chat web app. Why cant I write python code in the Django framework that does long polling where I dont send a response back the server until someone enters a new msg. What does Twisted provide that gives it an advantage for real-time apps like the chat app? Sorry I am obviously little confused about the need for an asynchronous framework. 回答1: Asynchronous servers support much
