This requires a client ID and client secret from Azure AD. You should either pass them to this constructor, or make sure that your Flask application config defines them, using the variables :envvar:`AZURE_OAUTH_CLIENT_ID` and :envvar:`AZURE_OAUTH_CLIENT_SECRET`. Args: client_id (str): The client ID for your application on Azure AD. client_secret (str): The client secret for your application on Azure AD scope (str, optional): comma-separated list of scopes for the OAuth token redirect_url (str): the URL to redirect to after the authentication dance is complete redirect_to (str): if ``redirect_url`` is not defined, the name of the view to redirect to after the authentication dance is complete. The actual URL will be determined by :func:`flask.url_for` login_url (str, optional): the URL path for the ``login`` view. Defaults to ``/azure`` authorized_url (str, optional): the URL path for the ``authorized`` view. Defaults to ``/azure/authorized``. session_class (class, optional): The class to use for creating a Requests session. Defaults to :class:`~flask_dance.consumer.requests.OAuth2Session`. storage: A token storage class, or an instance of a token storage class, to use for this blueprint. Defaults to :class:``. tenant: Determine which accounts are allowed to authenticate with Azure. `See the Azure documentation for more information about this parameter. <>`_ Defaults to ``common``. prompt (str, optional): Indicate the type of user interaction that is required. Valid values are ``login``, ``select_account``, ``consent``, ``admin_consent``. Learn more about the options `here. <>`_ Defaults to ``None`` domain_hint (str, optional): Provides a hint about the tenant or domain that the user should use to sign in. The value of the domain_hint is a registered domain for the tenant. If the tenant is federated to an on-premises directory, AAD redirects to the specified tenant federation server. Defaults to ``None`` login_hint (str, optional): Can be used to pre-fill the username/email address field of the sign-in page for the user, if you know their username ahead of time. Often apps use this parameter during re-authentication, having already extracted the username from a previous sign-in using the preferred_username claim. Defaults to ``None`` rule_kwargs (dict, optional): Additional arguments that should be passed when adding the login and authorized routes. Defaults to ``None``. :rtype: :class:`~flask_dance.consumer.OAuth2ConsumerBlueprint` :returns: A :doc:`blueprint <flask:blueprints>` to attach to your Flask app. """ scope = scope or ["openid", "email", "profile", "User.Read"] authorization_url_params = {} if login_hint: authorization_url_params["login_hint"] = login_hint if domain_hint: authorization_url_params["domain_hint"] = domain_hint if prompt: authorization_url_params["prompt"] = prompt azure_bp = OAuth2ConsumerBlueprint( "azure", __name__, client_id=client_id, client_secret=client_secret, scope=scope, base_url="", authorization_url=f"{tenant}/oauth2/v2.0/authorize", token_url=f"{tenant}/oauth2/v2.0/token", redirect_url=redirect_url, redirect_to=redirect_to, login_url=login_url, authorized_url=authorized_url, authorization_url_params=authorization_url_params, session_class=session_class, storage=storage, rule_kwargs=rule_kwargs, ) azure_bp.from_config["client_id"] = "AZURE_OAUTH_CLIENT_ID" azure_bp.from_config["client_secret"] = "AZURE_OAUTH_CLIENT_SECRET" @azure_bp.before_app_request def set_applocal_session(): g.flask_dance_azure = azure_bp.session return azure_bp
