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: .. testcode:: class GoogleOAuth2LoginHandler(tornado.web.RequestHandler, tornado.auth.GoogleOAuth2Mixin): @tornado.gen.coroutine def get(self): if self.get_argument('code', False): user = yield self.get_authenticated_user( redirect_uri='http://your.site.com/auth/google', code=self.get_argument('code')) # Save the user with e.g. set_secure_cookie else: yield self.authorize_redirect( redirect_uri='http://your.site.com/auth/google', client_id=self.settings['google_oauth']['key'], scope=['profile', 'email'], response_type='code', extra_params={'approval_prompt': 'auto'}) .. testoutput:: :hide: .. versionchanged:: 4.0 All of the callback interfaces in this module are now guaranteed to run their callback with an argument of ``None`` on error. Previously some functions would do this while others would simply terminate the request on their own. This change also ensures that errors are more consistently reported through the ``Future`` interfaces. � )�absolute_import�division�print_functionN)�TracebackFuture� return_future� chain_future)�gen)� httpclient)�escape)� url_concat)�gen_log)�ExceptionStackContext)� unicode_type� ArgReplacer�PY3c @ s e Zd ZdS )� AuthErrorN)�__name__� __module__� __qualname__� r r �I/opt/saltstack/salt/lib/python3.10/site-packages/salt/ext/tornado/auth.pyr a s r c C sP z|� � }W n ty! } zt�t|�� d }W Y d }~nd }~ww | |� d S �N)�resultr r �warning�str)�callback�futurer �er r r �_auth_future_to_callbacke s �� r c s& t � d��t�� �� �fdd��}|S )z�Similar to tornado.concurrent.return_future, but uses the auth module's legacy callback interface.

After authentication, the service will redirect back to the given callback URI with additional parameters including ``openid.mode``.

If you don't need all those attributes for your app, you can request fewer with the ax_attrs keyword argument. .. versionchanged:: 3.1 Returns a `.Future` and takes an optional callback.

The ``callback_uri`` may be omitted if you have previously registered a callback URI with the third-party service. For some services (including Friendfeed), 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. Note that this method is asynchronous, although it calls `.RequestHandler.finish` for you so it may not be necessary to pass a callback or use the `.Future` it returns. However, if this method is called from a function decorated with `.gen.coroutine`, you must call it with ``yield`` to keep the response from being closed prematurely. .. versionchanged:: 3.1 Now returns a `.Future` and takes an optional callback, for compatibility with `.gen.coroutine`. �_OAUTH_NO_CALLBACKSFz,This service does not support oauth_callbackN�_OAUTH_VERSION�1.0a)r> � extra_params) �getattr� ExceptionrM rN �_oauth_request_token_urlr& r' �_on_request_token�_OAUTH_AUTHORIZE_URL)r= r> r� rP r r r r �authorize_redirectF s0 ��� ��z OAuthMixin.authorize_redirectc C s� |}t �| �d��}| �dd�}| �d�}|s |�td�� dS | �d� dd� |�d�D �\}}||kr>|�td �� dS t||d �} |rJ|| d < |du rR| � � }|� | � | �t � | j|�� dS ) a Gets the OAuth authorized user and access token.

The result is a dictionary containing an ``access_token`` field ([among others](https://developers.google.com/identity/protocols/OAuth2WebServer#handlingtheresponse)). Unlike other ``get_authenticated_user`` methods in this package, this method does not return any additional information about the user. The returned access token can be used with `OAuth2Mixin.oauth2_request` to request additional information (perhaps from ``https://www.googleapis.com/oauth2/v2/userinfo``) Example usage: .. testcode:: class GoogleOAuth2LoginHandler(tornado.web.RequestHandler, tornado.auth.GoogleOAuth2Mixin): @tornado.gen.coroutine def get(self): if self.get_argument('code', False): access = yield self.get_authenticated_user( redirect_uri='http://your.site.com/auth/google', code=self.get_argument('code')) user = yield self.oauth2_request( "https://www.googleapis.com/oauth2/v1/userinfo", access_token=access["access_token"]) # Save the user and access token with # e.g. set_secure_cookie. else: yield self.authorize_redirect( redirect_uri='http://your.site.com/auth/google', client_id=self.settings['google_oauth']['key'], scope=['profile', 'email'], response_type='code', extra_params={'approval_prompt': 'auto'}) .. testoutput:: :hide: r� r� Zauthorization_code)r� r� r� r� Z grant_typerG z Content-Typez!application/x-www-form-urlencoded)rH �headersrI N) rM r; r< r� �_OAUTH_SETTINGS_KEYrN r� r& r' r� )r= r� r� r r� rI r r r rR Z s )� �z(GoogleOAuth2Mixin.get_authenticated_userc C s: |j r|�tdt|� �� dS t�|j�}|�|� dS )z7Callback function for the exchange to the access token.zGoogle auth error: %sN)r{ r| r r r r� rI r~ )r= r r r( r r r r� � s z"GoogleOAuth2Mixin._on_access_tokenN) r r r r� r� r� Z_OAUTH_USERINFO_URLr� r� r. rR r� r r r r r� B s 5r� c @ sR e Zd ZdZdZdZdZdZe ddd��Z d d � Z d d � Z e dd d��Z dS )�FacebookGraphMixinz;Facebook authentication using the new Graph API and OAuth2.z.https://graph.facebook.com/oauth/access_token?z&https://www.facebook.com/dialog/oauth?Fzhttps://graph.facebook.comNc C s^ | � � }||||d�}tg d��} |r| �|� |�| jdi |��t�| j||||| �� dS )a� Handles the login for the Facebook user, returning a user object.

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 @tornado.gen.coroutine def get(self): new_entry = yield 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? yield 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``. )r� r� N)�_FACEBOOK_BASE_URLr� r )r= r� r r� r� r( rQ Z oauth_futurer r r r� s 2 ��z#FacebookGraphMixin.facebook_requestr r� ) r r r r� r� r� r� r� r. rR r� r� r� r r r r r� � s �<�r� c C s� t � |�}|dd� \}}}|�� d |�� | } g } | �|�� � | �| � | �d�dd� t|�� �D ��� d�dd� | D ��} t�| d �g} | �t�|rU|d nd �� d �| �} t � | t�| �t j �}t �|�� �dd � S ) zxCalculates the HMAC-SHA1 OAuth signature for the given request.
