twisted

问题 I'm trying to run klein with twisted, so I can run twisted scripts on different paths (exp: example.com/example1 , example.com/example2 ). So I made a simple script: from klein import run, route, Klein from twisted.internet import reactor from twisted.web import proxy, server from twisted.python import log @route('/example') def home(request): site = server.Site(proxy.ReverseProxyResource('www.example.com', 80, b'')) reactor.listenTCP(80, site) reactor.run() run("My_IP_Address", 80) But

问题 using the answer of my previous question and another post I tried to implement facebook-chat from a browser. Here is what I did: on an ubuntu virtual machine, I have python 2.6.5 , python-twisted-conch 1:10.0.0-2 , python-twisted-names 10.0.0-1 , python-twisted-web 10.0.0-1 and python-twisted-words 10.0.0-2 already installed. I did not install jabberd2 server, I assumed facebook server is the Jabber/XMPP server in my case. Also I did not install pyopenssl. downloaded and untared punjab from

问题 I am writing server application in Python that listens for requests, processes them, and sends a response. All req/resp are send from the same address and port to the server application. I need to recv/send messages simultaneously, and the server need to recieve/send messages from/to the same port and address. I found some tutorials for asynchore sockets, but there are only examples for TCP connections. Unfortunately, I need UDP. When I change SOCK_STREAM to SOCK_DGRAM in the create method, I

问题 I am making api calls and receive a response back in json like so result = {'foo': '123.456', 'bar': '23', 'donald': 'trump', 'time': '2016-04-07T05:31:49.532124Z'} Although result is either a dictionary or a list, the contents are always strings. I want to cast these values to the appropriate type. (i.e. '123.456' to a float, '23' to an int, 'time' to a datetime.) My code works but it seems like there should be a simpler/more efficient way to do this. Is there? Here's my version from

问题 Got a simple question regarding twisted. I can create a trivial basic test with a web server like apache, where http://foo.com/index.php instantiates the index.php for the "foo" site/app... I'm trying to figure out how the heck I can create a twisted server, where I run different backend functions based on the input! I know, embarrasingly simple.. but none of what I've seen regarding twisted/server/client/etc.. discusses this. Comments/pointers/samples are greatly welcome. thanks 回答1: Have

问题 I'm also getting the same error while installing Twisted . Here's version info: Django : 1.9 Python : 3.5 Trying to install latest version of Django-channels Command used : pip install channels The error : running build_ext building 'twisted.test.raiser' extension error: [WinError 2] The system cannot find the file specified (Almost) full error message .......pip install channels Collecting channels Using cached channels-1.1.8-py2.py3-none-any.whl Collecting daphne~=1.3 (from channels) Using

问题 I haven't done twisted programming in a while so I'm trying to get back into it for a new project. I'm attempting to set up a twisted client that can take a list of servers as an argument, and for each server it sends an API GET call and writes the return message to a file. This API GET call should be repeated every 60 seconds. I've done it successfully with a single server using Twisted's agent class: from StringIO import StringIO from twisted.internet import reactor from twisted.internet

问题 How do you create multiple HTTPDownloader instance with partial download asynchronously? and does it assemble the file automatically after all download is done? 回答1: You must use Range HTTP header: Range. Request only part of an entity. Bytes are numbered from 0. Range: bytes=500-999 Ie. If you want download 1000 file in 4 parts, you will starts 4 downloads: 0-2499 2500-4999 5000-7499 7500-9999 And then simply join data from responses. To check file size you can use HEAD method: HEAD Asks for

问题 This is an extension of my question here: python twisted: enforcing a single connection per id I'm trying to enforce a singe connection per id. If a new connection comes in with the same id as an existing connection, I try to kill the old one and replace it with the new one. I do that by pausing the new one, killing the old one, then un-pausing the new one. I made the assumption that after pausing the transport on a connection I wouldn't get any further calls to dataReceived() but this doesn

问题 I have a small web server written using Twisted. One of the things I want to do is have it return a result from another web server as the response to loading a page. That is, the response to render_GET() at server A (via http://A.com/resource) should be the content of a different URL at server B (via http://B.com/resource2). The content returned by server B is dynamic, so I can't just cache it. Right now, server A can render pages just fine, it just can't render this remote resource. I've
