tornado

问题 I want to setup communication between a number of Tornado processes each acting as web-servers I.e. using tornado.web.RequestHandler . The idea is that i want a fully meshed network between the processes. I have 4 processes and I want to establish an ongoing permanent communication between them using the tornado.tcpserver and tornado.tcpclient : T1---T2 | \ /| | \/ | | / \ | T3---T4 I'm new to TCP programming however in the example I've seen in the tornado documentation: http://www.tornadoweb

问题 I would like to have users create and join a "rooms" so that they can collaborate. I'm looking at SockJs Multiplexer server and wondering if I can leverage some of that to create and broadcast to specific channel/room. In the example, a channel is created manually and client connects to that channel. Would treating these channels as rooms work? Is there a way to dynamically create these channels instead of manually declaring them on server? 回答1: Disclaimer: I didn't notice that you were

问题 Im creating a program in Python that reads a stream of data on an unknown interval. This program also sends this data through websockets. The program is the server and it sends the received data to the clients. This is the code of the server now: class WebSocketHandler(tornado.websocket.WebSocketHandler): def initialize(self): print 'Websocket opened' def open(self): print 'New connection' self.write_message('Test from server') def on_close(self): print 'Connection closed' def test(self):

问题 New to Tornado, and Redis, and implementing the beginnings of a listener / worker setup. I want to be able to LPUSH tasks onto a queue and RPOP them off. BRPOP seems like the best way to pop them off, as it will wait for one to be added if none are currently there. The problem is, whenever I use it, it never returns... however when I use RPOP I get the next item in the queue as expected. class ListenHandler(tornado.websocket.WebSocketHandler): uid = '' CHANNEL_TPL = "client_%s" RESPONSE_TPL =

问题 I read the book Introduction to Tornado. It introduces the asynchronous feature of tornado in an application using twitter search API. The code is as follows: class IndexHandler(tornado.web.RequestHandler): @tornado.web.asynchronous @tornado.gen.engine def get(self): query = self.get_argument('q') client = tornado.httpclient.AsyncHTTPClient() response = yield tornado.gen.Task(client.fetch, "http://search.twitter.com/search.json?" + \ urllib.urlencode({"q": query, "result_type": "recent", "rpp

问题 I have Django web-site working on tornado and nginx. I took this tornado launcher script (tornading.py) Then I'm using python openid that outputs some information to sys.stderr. As a result I get IOError. How can I redirect it using logging package? I thought about f = open("myfile.log", "w") sys.stderr = f or python tornado.py > /dev/null 2>&1 But what is the best way to solve it? 回答1: The best way would be if the openid library didn't print to stderr, but used some kind of logging API

问题 I am running python-2.7 with virtualenv on a unix server to which I do not have root access. I updated the module tornado using pip install tornado --upgrade because installing ipython required tornado >= 3.1.0 but only version 2.4 was installed by default on the server. However, when I try to open ipython, it still complains that I don't have the updated version. I confirmed that ipython is correctly aliased to the virtualenv, and that the upgrade had indeed produced tornado version 4.0 in

问题 I have some trouble with writing tests with AsyncHTTPTestCase for existing Tornado application that uses asyncio event loop. Here I prepare short model where I can reproduce issue: app.py from tornado.platform.asyncio import AsyncIOMainLoop import asyncio import tornado.web class MainHandler(tornado.web.RequestHandler): async def get(self, *args, **kwargs): self.write("200 OK") async def post(self, *args, **kwargs): self.write("201 OK") def make_app(): AsyncIOMainLoop().install() # here is

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 7 years ago .
