tornado

问题 I have a tornado application that makes requests to an http server using curl_httpclient. Every once in a while, all calls to the server returns incorrect results. In other words, the http responses are still fine, but the contents returned by the server becomes incorrect. I find I can get around this problem by terminating and restarting my process, which seems to mean that if I make a new TCP connection to the server and send new requests, things will be fine. Now my problem is how to make

问题 Below is the most simple example of my issue: When a request is made it will print Request via GET <__main__.MainHandler object at 0x104041e10> and then the request will remain open. Good! However, when you make another request it does not call the MainHandler.get method until the first connection has finished. How can I get multiple requests into the get method while having them remain long-polling. I'm passing arguments with each request that will get different results from a pub/sub via

问题 while installing juypter notebook on my ubuntu 14.04 I am getting this: ImportError: Tornado requires an up-to-date SSL module. This means Python 2.7.9+ or 3.4+ (although some distributions have backported the necessary changes to older versions). Pip is: pip 10.0.1 from /usr/local/lib/python2.7/dist-packages/pip (python 2.7) how to resolve this ? 回答1: Latest tornado library doesn't support your interpreter version. You have two options. Either install old tornado (recommended): pip install

问题 I am developing a web application using Tornado framework. Currently I am working on a front end view. This page actually displays a list of ids and a small note about that id. (Its a table with two columns) id -------- Note 100 ----- Note on 100 101 ----- Note on 101 ![Table with link on id and note on id][1] The ids are displayed dynamically. When I click on the id (its a link- anchor tag), it should take me to another page which has all the details about that id. Approach - I thought of

问题 In the RequestHandler we can use self.request.remote_ip to get the client ip address, but how to get the client port? And, if the client side implemented with tornado.simple_httpclient.SimpleAsyncHTTPClient , how to get the port for this connection? 回答1: Why do you want the client port? There's not currently a supported interface for this although I think self.request.connection.stream.socket.getpeername() will work (untested). I don't understand your second question about "request port" in

问题 This is a very similar problem to this question (Tornado POST 405: Method Not Allowed), but the dead simple answer for that question is still not working. There are also many, many more similar questions in the side bar -----> which are not related to Tornado, and did not provide me with a solution. Right now I am using Firefox on OSX. My tornado code is as follows: import tornado.ioloop import tornado.web class MainHandler(tornado.web.RequestHandler): def post(self): self.write("Hello, world

问题 I have this part of code: como_url = "".join(['http://', options.como_address, ':', options.como_port, '/ztc_config?netid=0&opcode_group=0&opcode=0&start=-20s&end=-1s']) http_client = AsyncHTTPClient() response = yield tornado.gen.Task(http_client.fetch, como_url) where I do an http request. I would add a connection timeout, to be sure that the previous code is been executed, so I can find my response. How can I add the timeout? I have to add it into the tornado.gen.Task call? I don't know

问题 the tornado server didn't do the favicon.ico by default,so i always get the info like these [W 130626 10:38:16 web:1514] 404 GET /favicon.ico (192.168.1.57) 0.57ms i use the web.staticfilehandler in various way include the source's example,and couldn't get it work, i got things work like this below. handlers = [ (r'/favicon.ico', tornado.web.StaticFileHandler,dict(url='/static/favicon.ico',permanent=False)), (r'/static/(.*)', tornado.web.StaticFileHandler, {"path": "plserver"}), ] i felt so

问题 I am new to Tornado and Python Threads. What I would like to achieve is the following: I have a Tornado web server which takes requests from users. I want to store some of the data locally and write it periodically to a data base as bulk-inserts. import tornado.ioloop import tornado.web import threading # Keep userData locally in memory UserData = {} def background(f): """ a threading decorator use @background above the function you want to thread (run in the background) """ def bg_f(*a, **kw

问题 I'm running tornado webserver for secure websocket connection on linux centos 6.6. I'm using Qt/c++ client to connect using a QWebsocket by opening a url like "wss://191.23.4.56/etr/job". I'm getting error like, " SSL sockets are not supported in this platform " What is this error about? 回答1: The error message "SSL sockets are not supported in this platform" is printed by QWebSocket::open() when the URL scheme is wss and QSslSocket::supportsSsl() returns false . The static member function
