问题 i have this small program taken from here from twisted.logger import Logger log = Logger() def handleData(data): log.debug("Got data: {data!r}.", data=data) handleData({'a':20}) This does not prints anything to the screen .why is that? 回答1: The default python logger is set to WARN level, so DEBUG messages are suppressed. You can make that code work like - import logging from twisted.logger import Logger log = Logger() log.setLevel(logging.DEBUG) def handleData(data): log.debug("Got data:

问题 I've looked at similar questions, but there always seems to be a whole lot of disagreement over the best way to handle threading with HTTP. What I specifically want to do: I'm using Python 2.7, and I want to try and thread HTTP requests (specifically, POSTing something), with a SOCKS5 proxy for each. The code I have already works, but is rather slow since it's waiting for each request (to the proxy server, then the web server) to finish before starting another. Each thread would most likely

问题 I have a twisted tcp client that I would like to periodically cause to connect, receive a stream of date for n seconds, then disconnect. After disconnecting n seconds would elapse before the process started over again. Below is a very abbreviated extract of the code I've tried so far. When I run the code the reactor.stop() is issued, and after the sleep elapses I get a twisted.internet error 'ReactorAlreadyRunning' when the reactor.run() is invoked in startClientConnection() I'm a raw novice

问题 There doesn't seem to be much out there right now on how to properly add WSS support to an Autobahn/Twisted setup. I'm starting with the Crossbar serial2ws example, which shows a WS-based connection between frontend and backend. I'd like to know how to adapt the serial2ws example for an SSL connection. I changed: # serial2ws.py router = args.router or 'ws://localhost:8080' to router = args.router or 'wss://localhost:8080' And on the website JS: connection = new autobahn.Connection({ url:

问题 I have an autobahn client using the ApplicationRunner class from autobahn to connect to a WAMP router (crossbar). In the main section it attaches my ApplicationSession class "REScheduler" like this: if __name__ == '__main__': from autobahn.twisted.wamp import ApplicationRunner runner = ApplicationRunner(url=u"ws://localhost:8080/ws", realm=u"RE_acct") runner.run(REScheduler, start_reactor=True, auto_reconnect=True) Now I need the reactor that the application runner started for other purposes

问题 I have a front-end web server written in Twisted Web, that interfaces with another web server. Clients upload files to my front-end server, which then sends the files along to the back-end server. I'd like to receive the uploaded file, and then send an immediate response to the client before sending the file on to the back-end server. That way the client doesn't have to wait for both uploads to occur before getting a response. I'm trying to do this by starting the upload to the back-end

问题 I am using protocol.Protocol to receive data from a server. As follows from twisted.internet.protocol import Protocol, Factory class MyProtocol(Protocol): def dataReceived(self, data): print data class MyFactory(Factory): def startedConnecting(self, connector): print 'Started to connect.' def buildProtocol(self, addr): print 'Connected.' return MyProtocol() When I receive large data, due to the TCP stream fragmentation, I only receive part of the incoming messages. I m trying to buffer the

问题 When I try and run this (see code below) I get the "connection made" response from the server and the command prompt to write an input. However when I try and enter the input it just hangs and the server doesn't seem to receive the message. Anyone know why this is? Thanks, please say if this isn't clear enough Here is my chat server: from twisted.protocols import basic class MyChat(basic.LineReceiver): def connectionMade(self): print "Got new client!" self.factory.clients.append(self) def

问题 Running this I found off the web #manhole from twisted.internet import reactor from twisted.manhole import telnet def createShellServer( ): print 'Creating shell server instance' factory = telnet.ShellFactory() port = reactor.listenTCP( 2000, factory) factory.namespace['x'] = application factory.namespace['s'] = s factory.username = 'me' factory.password = 'me' print 'Listening on port 2000' return port This worked, I was able to manhole into my twisted application. But I can't up-arrow to

问题 I wrote a TCP server using Python Twisted to send/receive binary data from clients. When a client close their application or calls the abortConnection method, I get the connectionLost event normally but when the client disconnects unexpectedly, I don't get the disconnect event, therefore, I can't remove the disconnected client from the queue. By unexpected disconnect I mean disabling the network adapter or lost the network connection somehow. My question is, how can I handle this sort of
