_getUser()source protected

_getUser( )

Similar to AuthComponent::user() except if the session user cannot be found, connected authentication objects will have their getUser() methods called. This lets stateless authentication methods function correctly.

Returns

boolean
True if a user can be found, false if one cannot.

_isAllowed()source protected

_isAllowed( Controller $controller )

Checks whether current action is accessible without authentication.

Parameters

Controller $controller

A reference to the instantiating controller object

Returns

boolean
True if action is accessible without authentication else false

_isLoginAction()source protected

_isLoginAction( Controller $controller )

Normalizes $loginAction and checks if current request URL is same as login action.

Parameters

Controller $controller

A reference to the controller object.

Returns

boolean
True if current action is login action else false.

_setDefaults()source protected

_setDefaults( )

Attempts to introspect the correct values for object properties.

Returns

boolean
True

_unauthenticated()source protected

_unauthenticated( Controller $controller )

Handles unauthenticated access attempt. First the unathenticated() method of the last authenticator in the chain will be called. The authenticator can handle sending response or redirection as appropriate and return true to indicate no furthur action is necessary. If authenticator returns null this method redirects user to login action. If it's an ajax request and $ajaxLogin is specified that element is rendered else a 403 http status code is returned.

Parameters

Controller $controller

A reference to the controller object.

Returns

boolean
True if current action is login action else false.

_unauthorized( Controller $controller )

Handle unauthorized access attempt

Parameters

Controller $controller

A reference to the controller object

Returns

boolean
Returns false

Throws

ForbiddenException

See

AuthComponent::$unauthorizedRedirect

Parameters

string $message

The message to set.

identify()source public

identify( CakeRequest $request , CakeResponse $response )

Use the configured authentication adapters, and attempt to identify the user by credentials contained in $request.

Overrides

Component::initialize()

isAuthorized()source public

isAuthorized( array|null $user null , CakeRequest $request null )

Check if the provided user is authorized for the request.

Uses the configured Authorization adapters to check whether or not a user is authorized. Each adapter will be checked in sequence, if any of them return true, then the user will be authorized for the request.

Parameters

array|null $user optional null

The user to check the authorization of. If empty the user in the session will be used.

CakeRequest $request optional null

The request to authenticate for. If empty, the current request will be used.

Returns

boolean
True if $user is authorized, otherwise false

loggedIn( )

Check whether or not the current user has data in the session, and is considered logged in.

Returns

boolean
true if the user is logged in, false otherwise

login()source public

login( array|null $user null )

Log a user in.

If a $user is provided that data will be stored as the logged in user. If $user is empty or not specified, the request will be used to identify a user. If the identification was successful, the user record is written to the session key specified in AuthComponent::$sessionKey. Logging in will also change the session id in order to help mitigate session replays.

Parameters

array|null $user optional null

Either an array of user data, or null to identify a user using the current request.

Returns

boolean
True on login success, false on failure

logout( )

Log a user out.

Returns the logout action to redirect to. Triggers the logout() method of all the authenticate objects, so they can perform custom logout logic.

Returns

string
AuthComponent::$logoutRedirect

requestAction()source public

requestAction( string|array $url , array $extra array() )

Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.

Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()

Passing POST and GET data

POST and GET data can be simulated in requestAction. Use $extra['url'] for GET data. The $extra['data'] parameter allows POST data simulation.

Parameters

string|array $url

String or array-based URL. Unlike other URL arrays in CakePHP, this URL will not automatically handle passed and named arguments in the $url parameter.

array $extra optional array()

if array includes the key "return" it sets the AutoRender to true. Can also be used to submit GET/POST data, and named/passed arguments.

Returns

mixed

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
