Submodules¶

keystoneauth1.identity.access module¶

class keystoneauth1.identity.access.AccessInfoPlugin(auth_ref, auth_url=None)¶

Bases: keystoneauth1.identity.base.BaseIdentityPlugin

A plugin that turns an existing AccessInfo object into a usable plugin.

There are cases where reuse of an auth_ref or AccessInfo object is warranted such as from a cache, from auth_token middleware, or another source.

Turn the existing access info object into an identity plugin. This plugin cannot be refreshed as the AccessInfo object does not contain any authorizing information.

Parameters:	auth_ref (keystoneauth1.access.AccessInfo) – the existing AccessInfo object. auth_url – the url where this AccessInfo was retrieved from. Required if using the AUTH_INTERFACE with get_endpoint. (optional)

get_auth_ref(session, **kwargs)¶

invalidate()¶

keystoneauth1.identity.base module¶

class keystoneauth1.identity.base.BaseIdentityPlugin(auth_url=None, reauthenticate=True)¶

Bases: keystoneauth1.plugin.BaseAuthPlugin

MIN_TOKEN_LIFE_SECONDS = 120¶

get_access(session, **kwargs)¶

Fetch or return a current AccessInfo object.

If a valid AccessInfo is present then it is returned otherwise a new one will be fetched.

Raises keystoneauth1.exceptions.http.HttpError:
Parameters:	session (keystoneauth1.session.Session) – A session object that can be used for communication.
	An error from an invalid HTTP response.
Returns:	Valid AccessInfo
Return type:	`keystoneauth1.access.AccessInfo`

get_auth_ref(session, **kwargs)¶

Obtain a token from an OpenStack Identity Service.

This method is overridden by the various token version plugins.

This function should not be called independently and is expected to be invoked via the do_authenticate function.

This function will be invoked if the AcessInfo object cached by the plugin is not valid. Thus plugins should always fetch a new AccessInfo when invoked. If you are looking to just retrieve the current auth data then you should use get_access.

Parameters:	session (keystoneauth1.session.Session) – A session object that can be used for communication.
Raises:	keystoneauth1.exceptions.response.InvalidResponse – The response returned wasn’t appropriate. keystoneauth1.exceptions.http.HttpError – An error from an invalid HTTP response.
Returns:	Token access information.
Return type:	`keystoneauth1.access.AccessInfo`

get_auth_state()¶

Retrieve the current authentication state for the plugin.

Retrieve any internal state that represents the authenticated plugin.

This should not fetch any new data if it is not present.

Returns:	a string that can be stored or None if there is no auth state present in the plugin. This string can be reloaded with set_auth_state to set the same authentication.
Return type:	str or None if no auth present.

get_cache_id()¶

Fetch an identifier that uniquely identifies the auth options.

The returned identifier need not be decomposable or otherwise provide any way to recreate the plugin.

This string MUST change if any of the parameters that are used to uniquely identity this plugin change. It should not change upon a reauthentication of the plugin.

Returns:	A unique string for the set of options
Return type:	str or None if this is unsupported or unavailable.

get_cache_id_elements()¶

Get the elements for this auth plugin that make it unique.

As part of the get_cache_id requirement we need to determine what aspects of this plugin and its values that make up the unique elements.

This should be overriden by plugins that wish to allow caching.

Returns:	The unique attributes and values of this plugin.
Return type:	A flat dict with a str key and str or None value. This is required as we feed these values into a hash. Pairs where the value is None are ignored in the hashed id.

get_discovery(session, url, authenticated=None)¶

Return the discovery object for a URL.

Check the session and the plugin cache to see if we have already performed discovery on the URL and if so return it, otherwise create a new discovery object, cache it and return it.

This function is expected to be used by subclasses and should not be needed by users.

Parameters:	session (keystoneauth1.session.Session) – A session object to discover with. url (str) – The url to lookup. authenticated (bool) – Include a token in the discovery call. (optional) Defaults to None (use a token if a plugin is installed).
Raises:	keystoneauth1.exceptions.discovery.DiscoveryFailure – if for some reason the lookup fails. keystoneauth1.exceptions.http.HttpError – An error from an invalid HTTP response.
Returns:	A discovery object with the results of looking up that URL.

get_endpoint(session, service_type=None, interface=None, region_name=None, service_name=None, version=None, allow={}, **kwargs)¶

Return a valid endpoint for a service.

If a valid token is not present then a new one will be fetched using the session and kwargs.

Raises keystoneauth1.exceptions.http.HttpError:
Parameters:	session (keystoneauth1.session.Session) – A session object that can be used for communication. service_type (string) – The type of service to lookup the endpoint for. This plugin will return None (failure) if service_type is not provided. interface (string) – The exposure of the endpoint. Should be public, internal, admin, or auth. auth is special here to use the auth_url rather than a URL extracted from the service catalog. Defaults to public. region_name (string) – The region the endpoint should exist in. (optional) service_name (string) – The name of the service in the catalog. (optional) version (tuple) – The minimum version number required for this endpoint. (optional) allow (dict) – Extra filters to pass when discovering API versions. (optional)
	An error from an invalid HTTP response.
Returns:	A valid endpoint URL or None if not available.
Return type:	string or None

get_project_id(session, **kwargs)¶

get_sp_auth_url(session, sp_id, **kwargs)¶

get_sp_url(session, sp_id, **kwargs)¶

get_token(session, **kwargs)¶

Return a valid auth token.

If a valid token is not present then a new one will be fetched.

Raises keystoneauth1.exceptions.http.HttpError:
Parameters:	session (keystoneauth1.session.Session) – A session object that can be used for communication.
	An error from an invalid HTTP response.
Returns:	A valid token.
Return type:	string

get_user_id(session, **kwargs)¶

invalidate()¶

Invalidate the current authentication data.

This should result in fetching a new token on next call.

A plugin may be invalidated if an Unauthorized HTTP response is returned to indicate that the token may have been revoked or is otherwise now invalid.

Returns:	True if there was something that the plugin did to invalidate. This means that it makes sense to try again. If nothing happens returns False to indicate give up.
Return type:	bool

set_auth_state(data)¶

Install existing authentication state for a plugin.

Take the output of get_auth_state and install that authentication state into the current authentication plugin.

keystoneauth1.identity.v2 module¶

class keystoneauth1.identity.v2.Auth(auth_url, trust_id=None, tenant_id=None, tenant_name=None, reauthenticate=True)¶

Bases: keystoneauth1.identity.base.BaseIdentityPlugin

Identity V2 Authentication Plugin.

Parameters:	auth_url (string) – Identity service endpoint for authorization. trust_id (string) – Trust ID for trust scoping. tenant_id (string) – Tenant ID for project scoping. tenant_name (string) – Tenant name for project scoping. reauthenticate (bool) – Allow fetching a new token if the current one is going to expire. (optional) default True

get_auth_data(headers=None)¶

Return the authentication section of an auth plugin.

Parameters:	headers (dict) – The headers that will be sent with the auth request if a plugin needs to add to them.
Returns:	A dict of authentication data for the auth type.
Return type:	dict

get_auth_ref(session, **kwargs)¶

has_scope_parameters¶: Return true if parameters can be used to create a scoped token.
