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. � )�absolute_import�division�print_functionN)�BytesIO)�Future)�escape)�httputil)� access_log)�web�� native_str)� unicode_type�PY3c C � t | t�sJ �| �d�S �N�latin1)� isinstance�bytes�decode��s� r �I/opt/saltstack/salt/lib/python3.10/site-packages/salt/ext/tornado/wsgi.py� to_wsgi_str: � r c C r r )r �str�encoder r r r � from_wsgi_str> r r c C � t | t�sJ �| S �N)r r r r r r r B � c C r r )r r r r r r r F r c @ s e Zd ZdZdd� ZdS )�WSGIApplicationz�A WSGI equivalent of `tornado.web.Application`. .. deprecated:: 4.0 Use a regular `.Application` and wrap it in `WSGIAdapter` instead. c C s t | �||�S r )� WSGIAdapter)�self�environ�start_responser r r �__call__R s zWSGIApplication.__call__N)�__name__� __module__� __qualname__�__doc__r& r r r r r!

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. .. versionadded:: 4.0 c s& t � t�r� fdd�| _d S � | _d S )Nc s t j�� | �S r )r � Applicationr& )�request�� applicationr r �<lambda>� s �z&WSGIAdapter.__init__.<locals>.<lambda>)r r! rR )r# rR r rQ r r2 � s zWSGIAdapter.__init__c C sh |d }t �t|�dd���}|t �t|�dd���7 }|�d�r)|d|d 7 }t�� }|�d�r8|d |d< |�d �rC|d |d < |D ]}|�d �rZ|| ||d d � �d d�< qE|�d �rl|d �t |d ��}nd}|d }|�dd�} |�d�r�|d } n|d } t ||t | |��} tj ||d||| | d�} | � � | �| � | jr�| j�| js�td��| jS )N�REQUEST_METHOD� SCRIPT_NAME� � PATH_INFO� QUERY_STRING�?� CONTENT_TYPE� Content-Type�CONTENT_LENGTHr6 �HTTP_� �_�-� wsgi.input� �wsgi.url_scheme� REMOTE_ADDRZ HTTP_HOST� SERVER_NAME�HTTP/1.1)rC �body�host� connectionz$request did not finish synchronously)� urllib_parse�quoter �getr � HTTPHeaders� startswith�replace�readr< r+ rK �HTTPServerRequestZ _parse_bodyrR r1 r/ � Exceptionr. ) r# r$ r% r, �urirC �keyrg rM rL rh ri rP r r r r& � sL � � � � zWSGIAdapter.__call__N)r' r( r) r* r2 r& r r r r r" � s r" c @ s4 e Zd ZdZdd� Zdd� Zedd� �Zdd � Zd S ) � WSGIContainera� 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. c C s || _ d S r )�wsgi_application)r# rv r r r r2 s zWSGIContainer.__init__c sl i � g �d� �fdd� }| � t�|�|�}z��|� d���}W t|d�r*|�� n t|d�r5|�� w w � s<td��� d �dd�\}}t |�}� d }t d d � |D ��}t � |�}|d krxd |vro|� dtt|��f� d|vrx|� d� d|vr�|� ddtjjj f� t�d||�} t�� } |D ] \} } | �| | � q�|jj| | |d� |j�� | �||� d S )Nc s | � d< |� d< �j S )N�statusrC )rH )rw Zresponse_headers�exc_info��data�responser r r% s z.WSGIContainer.__call__.<locals>.start_responserb �closez$WSGI app did not call start_responserw � � rC c s s � | ] \}}|� � V qd S r )�lowerr7 r r r � <genexpr># s � z)WSGIContainer.__call__.<locals>.<genexpr>i0 zcontent-lengthr6 z content-type)r[ ztext/html; charset=UTF-8ZserverZServerzTornadoServer/%srf )rD r ) rv ru r$ �extend�join�hasattrr| rr �splitr< �setr �utf8rH r rF �salt�ext�tornado�versionr ZResponseStartLinerm �addri rE rJ �_log) r# rP r% Z app_responserg � status_coder> rC Z header_setrB Z header_objrt �valuer ry r r& sH � � � � zWSGIContainer.__call__c C s� | j �d�}t|�dkr|d }t|d �}n | j }| jdkr!dnd}| jdttj| j d d d ��| j | j |t |�| j d | jtt�| j��tjd d d d�}d| jv rY| j�d�|d< d| jv rf| j�d�|d< | j�� D ]\}}||d|�dd��� < qk|S )zOConverts a `tornado.httputil.HTTPServerRequest` to a WSGI environment. �:� r r~ �httpsi� �P rV NF)�encodingZplus)r~ r T)rT rU rW rX rd re Z SERVER_PORTZSERVER_PROTOCOLz wsgi.versionrc ra z wsgi.errorszwsgi.multithreadzwsgi.multiprocessz wsgi.run_oncer[ rZ r6 r\ r] r` r_ )rh r� rF r< rM r, r r Z url_unescape�path�queryrL r r� r r� rg �sys�stderrrC �pop�itemsro �upper)rP Zhostportrh �portr$ rt r� r r r r$ 5 s> �� zWSGIContainer.environc C sb |dk rt j}n |dk rt j}nt j}d|�� }|jd |j d |j d }|d|||� d S )Ni� i� g @�@r} z (�)z %d %s %.2fms)r �info�warning�error� request_timer, rs rL )r# r� rP Z log_methodr� Zsummaryr r r r� Z s ��zWSGIContainer._logN) r' r( r) r* r2 r& � staticmethodr$ r� r r r r ru � s !( $ru )*r* � __future__r r r r� �ior Zsalt.ext.tornador� r� Zsalt.ext.tornado.concurrentr r r Zsalt.ext.tornado.logr r Zsalt.ext.tornado.escaper Zsalt.ext.tornado.utilr r � urllib.parse�parserj �urllibr r r rO r! rA Z set_result�HTTPConnectionr+ �objectrK r" ru rq Z HTTPRequestr r r r �<module> s8 5 N
