All the classes in this file are class mixins designed to be used with the `tornado.web.RequestHandler` class. They are used in two ways: * On a login handler, use methods such as ``authenticate_redirect()``, ``authorize_redirect()``, and ``get_authenticated_user()`` to establish the user's identity and store authentication tokens to your database and/or cookies. * In non-login handlers, use methods such as ``facebook_request()`` or ``twitter_request()`` to use the authentication tokens to make requests to the respective services. They all take slightly different arguments due to the fact all these services implement authentication and authorization slightly differently. See the individual service classes below for complete documentation. Example usage for Google OAuth: .. testsetup:: import urllib .. testcode:: class GoogleOAuth2LoginHandler(tornado.web.RequestHandler, tornado.auth.GoogleOAuth2Mixin): async def get(self): # Google requires an exact match for redirect_uri, so it's # best to get it from your app configuration instead of from # self.request.full_uri(). redirect_uri = urllib.parse.urljoin(self.application.settings['redirect_base_uri'], self.reverse_url('google_oauth')) async def get(self): if self.get_argument('code', False): access = await self.get_authenticated_user( redirect_uri=redirect_uri, code=self.get_argument('code')) user = await self.oauth2_request( "https://www.googleapis.com/oauth2/v1/userinfo", access_token=access["access_token"]) # Save the user and access token. For example: user_cookie = dict(id=user["id"], access_token=access["access_token"]) self.set_signed_cookie("user", json.dumps(user_cookie)) self.redirect("/") else: self.authorize_redirect( redirect_uri=redirect_uri, client_id=self.get_google_oauth_settings()['key'], scope=['profile', 'email'], response_type='code', extra_params={'approval_prompt': 'auto'}) .. testoutput:: :hide: � N)� httpclient)�escape)� url_concat)� unicode_type)�RequestHandler)�List�Any�Dict�cast�Iterable�Union�Optionalc @ s e Zd ZdS )� AuthErrorN)�__name__� __module__� __qualname__� r r �?/usr/local/CyberCP/lib/python3.10/site-packages/tornado/auth.pyr ] s r c @ s� e Zd ZdZdg d�fdee dee ddfdd�Z dd eej de ee f fd d �Z g dfdede e d ee de eef fd d�Zdejde ee f fdd�Zdej fdd�ZdS )� OpenIdMixinz�Abstract implementation of OpenID and Attribute Exchange.

After authentication, the service will redirect back to the given callback URI with additional parameters including ``openid.mode``. We request the given attributes for the authenticated user by default (name, email, language, and username). If you don't need all those attributes for your app, you can request fewer with the ax_attrs keyword argument. .. versionchanged:: 6.0 The ``callback`` argument was removed and this method no longer returns an awaitable object.

This method should be called by the handler that receives the redirect from the `authenticate_redirect()` method (which is often the same as the one that calls it; in that case you would call `get_authenticated_user` if the ``openid.mode`` parameter is present and `authenticate_redirect` if it is not). The result of this method will generally be used to set a cookie. .. versionchanged:: 6.0 The ``callback`` argument was removed.

The ``callback_uri`` may be omitted if you have previously registered a callback URI with the third-party service. For some services, you must use a previously-registered callback URI and cannot specify a callback via this method. This method sets a cookie called ``_oauth_request_token`` which is subsequently used (and cleared) in `get_authenticated_user` for security purposes. This method is asynchronous and must be called with ``await`` or ``yield`` (This is different from other ``auth*_redirect`` methods defined in this module). It calls `.RequestHandler.finish` for you so you should not write any other response after it returns. .. versionchanged:: 3.1 Now returns a `.Future` and takes an optional callback, for compatibility with `.gen.coroutine`. .. versionchanged:: 6.0 The ``callback`` argument was removed.

Example usage: .. testcode:: class FacebookGraphLoginHandler(tornado.web.RequestHandler, tornado.auth.FacebookGraphMixin): async def get(self): redirect_uri = urllib.parse.urljoin( self.application.settings['redirect_base_uri'], self.reverse_url('facebook_oauth')) if self.get_argument("code", False): user = await self.get_authenticated_user( redirect_uri=redirect_uri, client_id=self.settings["facebook_api_key"], client_secret=self.settings["facebook_secret"], code=self.get_argument("code")) # Save the user with e.g. set_signed_cookie else: self.authorize_redirect( redirect_uri=redirect_uri, client_id=self.settings["facebook_api_key"], extra_params={"scope": "user_posts"}) .. testoutput:: :hide: This method returns a dictionary which may contain the following fields: * ``access_token``, a string which may be passed to `facebook_request` * ``session_expires``, an integer encoded as a string representing the time until the access token expires in seconds. This field should be used like ``int(user['session_expires'])``; in a future version of Tornado it will change from a string to an integer. * ``id``, ``name``, ``first_name``, ``last_name``, ``locale``, ``picture``, ``link``, plus any fields named in the ``extra_fields`` argument. These fields are copied from the Facebook graph API `user object <https://developers.facebook.com/docs/graph-api/reference/user>`_ .. versionchanged:: 4.5 The ``session_expires`` field was updated to support changes made to the Facebook API in March 2017. .. versionchanged:: 6.0 The ``callback`` argument was removed.

Query string arguments should be given as keyword arguments. An introduction to the Facebook Graph API can be found at http://developers.facebook.com/docs/api Many methods require an OAuth access token which you can obtain through `~OAuth2Mixin.authorize_redirect` and `get_authenticated_user`. The user returned through that process includes an ``access_token`` attribute that can be used to make authenticated requests via this method. Example usage: .. testcode:: class MainHandler(tornado.web.RequestHandler, tornado.auth.FacebookGraphMixin): @tornado.web.authenticated async def get(self): new_entry = await self.facebook_request( "/me/feed", post_args={"message": "I am posting from my Tornado application!"}, access_token=self.current_user["access_token"]) if not new_entry: # Call failed; perhaps missing permission? self.authorize_redirect() return self.finish("Posted a message!") .. testoutput:: :hide: The given path is relative to ``self._FACEBOOK_BASE_URL``, by default "https://graph.facebook.com". This method is a wrapper around `OAuth2Mixin.oauth2_request`; the only difference is that this method takes a relative path, while ``oauth2_request`` takes a complete url. .. versionchanged:: 3.1 Added the ability to override ``self._FACEBOOK_BASE_URL``. .. versionchanged:: 6.0 The ``callback`` argument was removed.
