authentication schemes.

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'})

   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.

        all those attributes for your app, you can request fewer with
        the ax_attrs keyword argument.

        This method should be called by the handler that receives the

        is present and `authenticate_redirect` if it is not).

OAuthMixina+Abstract implementation of OAuth 1.0 and 1.0a.

    See `TwitterMixin` below for an example implementation.

    Class attributes:

    * ``_OAUTH_AUTHORIZE_URL``: The service's OAuth authorization url.
    * ``_OAUTH_ACCESS_TOKEN_URL``: The service's OAuth access token url.
    * ``_OAUTH_VERSION``: May be either "1.0" or "1.0a".
    * ``_OAUTH_NO_CALLBACKS``: Set this to True if the service requires
      advance registration of callbacks.

    Subclasses must also override the `_oauth_get_user_future` and
    `_oauth_consumer_token` methods.

        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

        The path should not include the format or API version number.
        (we automatically use JSON format and API version 1).

        If the request is a POST, ``post_args`` should be provided. Query
        string arguments should be given as keyword arguments.

        All the Twitter methods are documented at http://dev.twitter.com/

        Many methods require an OAuth access token which you can
        obtain through `~OAuthMixin.authorize_redirect` and
        `~OAuthMixin.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.TwitterMixin):
                @tornado.web.authenticated
                @tornado.gen.coroutine
                def get(self):
                    new_entry = yield self.twitter_request(
                        "/statuses/update",
                        post_args={"status": "Testing Tornado Web Server"},
                        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!")

�ZdS)�GoogleOAuth2MixinaGoogle authentication using OAuth2.

    In order to use, register your application with Google and copy the
    relevant parameters to your application settings.

    * Go to the Google Dev Console at http://console.developers.google.com
    * Select a project, or create a new one.
    * In the sidebar on the left, select APIs & Auth.
    * In the list of APIs, find the Google+ API service and set it to ON.
    * In the sidebar on the left, select Credentials.
    * In the OAuth section of the page, select Create New Client ID.
    * Set the Redirect URI to point to your auth handler
    * Copy the "Client secret" and "Client ID" to the application settings as
      {"google_oauth": {"key": CLIENT_ID, "secret": CLIENT_SECRET}}

akHandles the login for the Google user, returning an 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):

                            "https://www.googleapis.com/oauth2/v1/userinfo",
                            access_token=access["access_token"])

        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
