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. i(tabsolute_importtdivisiontprint_functionN(tBytesIO(tFuture(tescape(thttputil(t access_log(tweb(t native_str(t unicode_typetPY3cC`s"t|tƒst‚|jdƒS(Ntlatin1(t isinstancetbytestAssertionErrortdecode(ts((s+lib/python2.7/site-packages/tornado/wsgi.pyt to_wsgi_str9scC`s"t|tƒst‚|jdƒS(NR (R tstrRtencode(R((s+lib/python2.7/site-packages/tornado/wsgi.pyt from_wsgi_str=scC`st|tƒst‚|S(N(R RR(R((s+lib/python2.7/site-packages/tornado/wsgi.pyRAscC`st|tƒst‚|S(N(R RR(R((s+lib/python2.7/site-packages/tornado/wsgi.pyREstWSGIApplicationcB`seZdZd„ZRS(sΚA WSGI equivalent of `tornado.web.Application`. .. deprecated:: 4.0 Use a regular `.Application` and wrap it in `WSGIAdapter` instead.

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. In multithreaded WSGI servers on Python 3, it may be necessary to permit `asyncio` to create event loops on any thread. Run the following at startup (typically import time for WSGI applications):: import asyncio from tornado.platform.asyncio import AnyThreadEventLoopPolicy asyncio.set_event_loop_policy(AnyThreadEventLoopPolicy()) .. versionadded:: 4.0 .. deprecated:: 5.1 This class is deprecated and will be removed in Tornado 6.0.
