问题 I need to write a proxy like program in Python, the work flow is very similar to a web proxy. The program sits in between the client and the server, incept requests sent by the client to the server, process the request, then send it to the original server. Of course the protocol used is a private protocol uses TCP. To minimize the effort, I want to use Python Twisted to handle the request receiving (the part acts as a server) and resending (the part acts as a client). To maximum the

问题 I'm having trouble installing twisted pip --version pip 1.1 from /home/chris/GL/GLBackend/glenv/lib/python2.7/site-packages/pip-1.1-py2.7.egg (python 2.7) Create a virtual environment chris@chris-mint ~/GL/GLBackend $ sudo virtualenv -p python2.7 glenv Running virtualenv with interpreter /usr/bin/python2.7 New python executable in glenv/bin/python2.7 Also creating executable in glenv/bin/python Installing distribute..............................................................................

问题 There're basically two issues I'd like to resolve: Client side send query string when initializing the connection to server Server side validate user token in handshake (not after the connection is established and then validate streaming message that contains the token) and set user session accordingly. I read a article (https://auth0.com/blog/2014/01/15/auth-with-socket-io/) that talks about this process implemented in nodejs, just wonder if the same function can be achieved by using python.

问题 I have a simple proxy script where I use installResolver function to choose where the script reads its hosts file: from twisted.internet import reactor from twisted.web import proxy, server from twisted.python import log from twisted.names import client def createResolver(servers=None, resolvconf=None, hosts=None): if platform.getType() == 'posix': if resolvconf is None: resolvconf = b'/etc/resolv.conf' if hosts is None: hosts = b'/root/example' theResolver = Resolver(resolvconf, servers)

问题 I was trying to send an image file using tcp from server to client. I tried opening the file, reading it and then transporting it using self.transport.write. On the client side, when I receive data, I open a file named Image in append mode, and write to it. client: class EchoClient(protocol.Protocol): def dataReceived(self, data): print 'writing to file' f = open('image.png','a') f.write(data) f.close() server (inherits Protocol): //somewhere in the code image = open(self.newdict[device_str]

问题 I am trying to create a web crawler with python and twisted.What happend is that at the time of calling reactor.run() I don't know all the link to get. so the code goes like: def crawl(url): d = getPage(url) d.addCallback(handlePage) reactor.run() and the handle page has something like: def handlePage(output): urls = getAllUrls(output) So now I need to apply the crawl() on each of the url in urls.How do I do that?Should I stop the reactor and start again?If I am missing something obvious

问题 So thanks to a couple of users here, I now have a (almost) working SMTP Server that supports switching from plain text to TLS connection as required. Basic server code is: from twisted.internet import ssl, protocol, defer, task, endpoints from twisted.protocols.basic import LineReceiver from twisted.python.modules import getModule from OpenSSL.crypto import load_privatekey, load_certificate, FILETYPE_PEM from custom_esmtp import mySMTP def main(reactor): caCertFile = open("/opt/tesa/etc/certs

问题 I have an IRC bot that I wrote using the Twisted Python IRC protocols. I want to be able to run commands while still allowing the bot to listen and execute other commands simultaneously. For example, let's say I have command that will print a large text file to a channel. If I wanted to stop the command while it was running by entering "!stop" into the channel, how could I accomplish this? Or let's say I want to do "!print largefile" in one channel and then go to a different channel and type

问题 I'm a complete Twisted AND Python noob, so my apologies if any of my terminology is wrong or anything I've done is silly. Nonetheless.... I've implemented my servers in the following way: def makeServer(application, port): factory = protocol.ServerFactory() factory.protocol = MyChat factory.clients = [] tempServer = internet.TCPServer(port, factory) tempServer.setServiceParent(application) return tempServer application = service.Application("chatserver") server1 = makeServer(application, port
