## Property Details

$optional public property (available since version 2.0.7)

List of action IDs that this filter will be applied to, but auth failure will not lead to error. It may be used for actions, that are allowed for public, but return some additional data for authenticated users. Defaults to empty, meaning authentication is not optional for any action. Since version 2.0.10 action IDs can be specified as wildcards, e.g. `site/*`.

See also isOptional().

public array $optional = []
$request public property

The current request. If not set, the `request` application component will be used.

public yii\web\Request $request = null
$response public property

The response to be sent. If not set, the `response` application component will be used.

public yii\web\Response $response = null
$user public property

The user object representing the user authentication status. If not set, the `user` application component will be used.

public yii\web\User $user = null

## Method Details

beforeAction() public method

This method is invoked right before an action is to be executed (after all possible filters.) You may override this method to do last-minute preparation for the action.

public boolean beforeAction ( $action )
$action | yii\base\Action | The action to be executed.
return | boolean | Whether the action should continue to be executed.

challenge() public method

Generates challenges upon authentication failure.

For example, some appropriate HTTP headers may be generated.

public void challenge ( $response )
$response | yii\web\Response |

handleFailure() public method

Handles authentication failure.

The implementation should normally throw UnauthorizedHttpException to indicate authentication failure.

public void handleFailure ( $response )
$response | yii\web\Response |
throws | yii\web\UnauthorizedHttpException |

isOptional() protected method (available since version 2.0.7)

Checks, whether authentication is optional for the given action.

See also $optional.

protected boolean isOptional ( $action )
$action | yii\base\Action | Action to be checked.
return | boolean | Whether authentication is optional or not.
