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 via the `WSGIContainer` class, which makes it possible to run applications using other WSGI frameworks on the Tornado HTTP server. The reverse is not supported; the Tornado `.Application` and `.RequestHandler` classes are designed for use with the Tornado `.HTTPServer` and cannot be used in a generic WSGI container. � N)�BytesIO)�dummy_executor)�escape)�httputil)�IOLoop)� access_log)�List�Tuple�Optional�Callable�Any�Dict�Text)� TracebackType)�Type)�WSGIApplication�s�returnc C s t | t�sJ �| �d�S )N�latin1)� isinstance�bytes�decode)r � r �B/usr/local/CyberPanel/lib/python3.10/site-packages/tornado/wsgi.py� to_wsgi_str6 s r c @ s� e Zd ZdZ ddddeejj ddfdd�Zd e j ddfd d �Z d e j ddfd d �Z d e j de eef fdd�Zded e j ddfdd�ZdS )� WSGIContainera� Makes a WSGI-compatible application runnable on Tornado's HTTP server. .. warning:: WSGI is a *synchronous* interface, while Tornado's concurrency model is based on single-threaded *asynchronous* execution. Many of Tornado's distinguishing features are not available in WSGI mode, including efficient long-polling and websockets. The primary purpose of `WSGIContainer` is to support both WSGI applications and native Tornado ``RequestHandlers`` in a single process. WSGI-only applications are likely to be better off with a dedicated WSGI server such as ``gunicorn`` or ``uwsgi``. Wrap a WSGI application in a `WSGIContainer` to make it implement the Tornado `.HTTPServer` ``request_callback`` interface. The `WSGIContainer` object can then be passed to classes from the `tornado.routing` module, `tornado.web.FallbackHandler`, or to `.HTTPServer` directly. This class is intended to let other frameworks (Django, Flask, etc) run on the Tornado HTTP server and I/O loop. Realistic usage will be more complicated, but the simplest possible example uses a hand-written WSGI application with `.HTTPServer`:: def simple_app(environ, start_response): status = "200 OK" response_headers = [("Content-type", "text/plain")] start_response(status, response_headers) return [b"Hello world!\n"] async def main(): container = tornado.wsgi.WSGIContainer(simple_app) http_server = tornado.httpserver.HTTPServer(container) http_server.listen(8888) await asyncio.Event().wait() asyncio.run(main()) The recommended pattern is to use the `tornado.routing` module to set up routing rules between your WSGI application and, typically, a `tornado.web.Application`. Alternatively, `tornado.web.Application` can be used as the top-level router and `tornado.web.FallbackHandler` can embed a `WSGIContainer` within it. If the ``executor`` argument is provided, the WSGI application will be executed on that executor. This must be an instance of `concurrent.futures.Executor`, typically a ``ThreadPoolExecutor`` (``ProcessPoolExecutor`` is not supported). If no ``executor`` is given, the application will run on the event loop thread in Tornado 6.3; this will change to use an internal thread pool by default in Tornado 7.0. .. warning:: By default, the WSGI application is executed on the event loop's thread. This limits the server to one request at a time (per process), making it less scalable than most other WSGI servers. It is therefore highly recommended that you pass a ``ThreadPoolExecutor`` when constructing the `WSGIContainer`, after verifying that your application is thread-safe. The default will change to use a ``ThreadPoolExecutor`` in Tornado 7.0. .. versionadded:: 6.3 The ``executor`` parameter. .. deprecated:: 6.3 The default behavior of running the WSGI application on the event loop thread is deprecated and will change in Tornado 7.0 to use a thread pool by default.
