Tornado Web Server
|
||
|
|
==================
|
||
|
|
|
||
|
|
`Tornado <http://www.tornadoweb.org>`_ is a Python web framework and
|
||
|
|
asynchronous networking library, originally developed at `FriendFeed
|
||
|
|
<http://friendfeed.com>`_. By using non-blocking network I/O, Tornado
|
||
|
|
can scale to tens of thousands of open connections, making it ideal for
|
||
|
|
`long polling <http://en.wikipedia.org/wiki/Push_technology#Long_polling>`_,
|
||
|
|
`WebSockets <http://en.wikipedia.org/wiki/WebSocket>`_, and other
|
||
|
|
applications that require a long-lived connection to each user.

Hello, world
|
||
|
|
------------
|
||
|
|
|
||
|
|
Here is a simple "Hello, world" example web app for Tornado:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
import tornado.ioloop
|
||
|
|
import tornado.web
|
||
|
|
|
||
|
|
class MainHandler(tornado.web.RequestHandler):
|
||
|
|
def get(self):
|
||
|
|
self.write("Hello, world")
|
||
|
|
|
||
|
|
def make_app():
|
||
|
|
return tornado.web.Application([
|
||
|
|
(r"/", MainHandler),
|
||
|
|
])
|
||
|
|
|
||
|
|
if __name__ == "__main__":
|
||
|
|
app = make_app()
|
||
|
|
app.listen(8888)
|
||
|
|
tornado.ioloop.IOLoop.current().start()
|
||
|
|
|
||
|
|
This example does not use any of Tornado's asynchronous features; for
|
||
|
|
that see this `simple chat room
