j( Z) d S( s� WSGI support for the Tornado web framework.
WSGI is the Python standard for web servers, and allows for interoperability
between Tornado and other Python web frameworks and servers. This module
provides WSGI support in two ways:
* `WSGIAdapter` converts a `tornado.web.Application` to the WSGI application
interface. This is useful for running a Tornado app on another
HTTP server, such as Google App Engine. See the `WSGIAdapter` class
documentation for limitations that apply.
* `WSGIContainer` lets you run other WSGI applications and frameworks on the
Tornado HTTP server. For example, with this class you can mix Django
and Tornado handlers in a single server.

Example usage::
import tornado.web
import tornado.wsgi
import wsgiref.simple_server
class MainHandler(tornado.web.RequestHandler):
def get(self):
self.write("Hello, world")
if __name__ == "__main__":
application = tornado.web.Application([
(r"/", MainHandler),
])
wsgi_app = tornado.wsgi.WSGIAdapter(application)
server = wsgiref.simple_server.make_server('', 8888, wsgi_app)
server.serve_forever()
See the `appengine demo
<https://github.com/tornadoweb/tornado/tree/stable/demos/appengine>`_
for an example of using this module to run a Tornado app on Google
App Engine.
In WSGI mode asynchronous methods are not supported. This means
that it is not possible to use `.AsyncHTTPClient`, or the
`tornado.auth` or `tornado.websocket` modules.

WSGIContainerc B� s8 e Z d Z d � Z d � Z e d � � Z d � Z RS( s� Makes a WSGI-compatible function runnable on Tornado's HTTP server.
.. warning::
WSGI is a *synchronous* interface, while Tornado's concurrency model
is based on single-threaded asynchronous execution. This means that
running a WSGI app with Tornado's `WSGIContainer` is *less scalable*
than running the same app in a multi-threaded WSGI server like
``gunicorn`` or ``uwsgi``. Use `WSGIContainer` only when there are
benefits to combining Tornado and WSGI in the same process that
outweigh the reduced scalability.
Wrap a WSGI function in a `WSGIContainer` and pass it to `.HTTPServer` to
run it. For example::
def simple_app(environ, start_response):
status = "200 OK"
response_headers = [("Content-type", "text/plain")]
start_response(status, response_headers)
return ["Hello world!\n"]
container = tornado.wsgi.WSGIContainer(simple_app)
http_server = tornado.httpserver.HTTPServer(container)
http_server.listen(8888)
tornado.ioloop.IOLoop.current().start()
This class is intended to let other frameworks (Django, web.py, etc)
run on the Tornado HTTP server and I/O loop.
The `tornado.web.FallbackHandler` class is often useful for mixing
Tornado and WSGI apps in the same server. See
https://github.com/bdarnell/django-tornado-demo for a complete example.
