Authentication strategy implementations for Core.

class AuthStrategy(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​

Base authentication strategy interface.

__init__(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​

Initialize strategy.

Args: iam_url: IAM service URL storage: Optional token storage backend

authenticate(**kwargs: Any) -> Tuple[Dict[str, Any], str]​

Authenticate and return (user, token) tuple.

Returns​

  • tuple of (dict, str)

    Tuple of (user_dict, token_string).

Raises​

  • Exception

    If authentication fails

can_handle(**kwargs: Any) -> bool​

Check if this strategy can handle the given options.

Returns​

  • bool

    True if this strategy can authenticate with given options.

class TokenAuthStrategy(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​

Token-based authentication strategy.

can_handle(**kwargs: Any) -> bool​

Check if token is provided.

authenticate(**kwargs: Any) -> Tuple[Dict[str, Any], str]​

Authenticate using existing token.

class CredentialsAuthStrategy(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​

Credentials-based authentication strategy.

can_handle(**kwargs: Any) -> bool​

Check if handle and password are provided.

authenticate(**kwargs: Any) -> Tuple[Dict[str, Any], str]​

Authenticate using handle and password.

class StorageAuthStrategy(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​

Storage-based authentication strategy.

can_handle(**kwargs: Any) -> bool​

Check if storage has a token.

authenticate(**kwargs: Any) -> Tuple[Dict[str, Any], str]​

Authenticate using token from storage.

class BrowserAuthStrategy(iam_url: str, storage: Optional[datalayer_core.authn.storage.TokenStorage] = None)​
