I want to write a simple SSL HTTP client in Python and have heard about the Twisted framework. I need to be able to authenticate with a REST service - so I was thinking I'd just POST a user name and password to the target server. Assuming authentication is successful, the client will receive a cookie. Will an HTTP client built on Twist...
I want to store http request line from telnet or browser into a list in python. I am using basic.LineReceiver protocol ...
I want to use Twisted to rebuild the communication part of an existing application. This application does send data from the client to the server, only this way round, the server does not send anything. How do I accomplish this with the event-driven concept of Twisted? I currently use the connectionMade method of Protocol, but I don't t...

Howdy! I am trying to write a simple program using Twisted framework and I am struggling with resolving (or even with imaging how to write it) issue I couldnt find any relevant documentation for: The main reactor uses two factories, one custom, listening for TCP connections on given port (say, 8000) and second one, to log into given IR...
When I try to print an unicode string on my dev server it works correctly but production server raises exception. File "/home/user/twistedapp/server.py", line 97, in stringReceived print "sent:" + json File "/usr/lib/python2.6/dist-packages/twisted/python/log.py", line 555, in write d = (self.buf + data).split('\n') exceptions.U...
I want to transmit data from a Queue using Twisted. I currently use a push producer to poll the queue for items and write to the transport. class Producer: implements(interfaces.IPushProducer) def __init__(self, protocol, queue): self.queue = queue self.protocol = protocol def resumeProducing(self): ...
I am building xml rpc service using twisted and I would like to use None just as it can be done in standard python lib. How can I pass allow_none to the twisted version of xmlrpc server? EDIT In [28]: sock = rpc.ServerProxy('http://localhost:7080',allow_none=True) In [29]: sock Out[29]: <ServerProxy for localhost:7080/RPC2> In [30]: ...
I'm currently writing a project in Python which has a client and a server part. I have troubles with the network communication, so I need to explain some things... The client mainly does operations the server tells him to and sends the results of the operations back to the server. I need a way to communicate bidirectional on a TCP socke...

My twisted python program keeps spewing this message ever so often: Unhandled error in Deferred: Traceback (most recent call last): File "c:\python25\lib\site-packages\twisted\internet\defer.py", line 757, in gotResult _inlineCallbacks(r, g, deferred) File "c:\python25\lib\site-packages\twisted\internet\defer.py", line 747, in ...
Consider the following code: df = defer.Deferred() def hah(_): raise ValueError("4") df.addCallback(hah) df.callback(hah) When it runs, that exception just gets eaten. Where did it go? How can I get it to be displayed? Doing defer.setDebugging(True) has no effect. I ask this because other times, I get a printout saying "Unhandled err...
How do I begin learning Twisted? What books, documentation or tutorial do you guys recommend? The reason I asked this question is that I think learning Twisted would help me otherwise also in learning concepts related to network programming (terminologies and how it works and stuff) I have heard that the documentation for Twisted is not...
I am trying to teach myself some rudimentary Twisted programming thanks to this tutorial and many others. I have come to this current example which I Can't figure out why it's doing what it is doing. Short summary: I have instantiated three reactors that count down from 5 to 1 with different delays in their counting. Only thing is, it ...
I'm making several HTTP requests with twisted.web.client.getPage, and would like to be able to cancel some of them at the user's request. Ideally I would like to do something like: # Pseudocode, getPage doesn't work like this: getPage(url1, "group1") getPage(url2, "group1") getPage(url3, "group1") ... # Later on reactor.cancel_all("gro...
I am writing a test for a function that downloads the data from an url with Twisted (I know about twisted.web.client.getPage, but this one adds some extra functionality). Either ways, I want to use nosetests since I am using it throughout the project and it doesn't look appropriate to use Twisted Trial only for this particular test. So w...
Is there any reason to use one over the other? Do they have the same performance? ...
Hey, I got a ReconnectingClientFactory and I wonder if I can somehow define protocol-instance-based connectionMade/connectionLost callbacks so that i can use the factory to connect to different hosts ans distinguish between each connection. Thanks in advance. ...
Ok I have been writing a proxy to take http GET requests and translate them into HTTP POST requests (because a lot of media players for python only support GET). So I know am working on caching those results that way I only download a url once, I moved a lot of code from the super class to the sub class and changed it so that I could sen...
I've decided to dip my toe into the world of asynchronous python with the help of twisted. I've implemented some of the examples from the documentation, but I'm having a difficult time finding an example of the, very simple, client I'm trying to write. In short I'd like a client which establishes a tcp connection with a server and then ...
