Method Detail

__construct()source public

__construct( Cake\Controller\ComponentRegistry $registry , array $config = [] )

Constructor

Parameters

Cake\Controller\ComponentRegistry $registry
The Component registry used on this request.
array $config optional []
Array of config to use.

_findUser()source protected

_findUser( string $username , string|null $password = null )

Find a user record using the username and password provided.

Input passwords will be hashed even when a user doesn't exist. This helps mitigate timing attacks that are attempting to find valid usernames.

Parameters

string $username
The username/identifier.
string|null $password optional null

The password, if not provided password checking is skipped and result of find is returned.

Returns

boolean|array
Either false on failure, or an array of user data.

_query()source protected

_query( string $username )

Get query object for fetching user from database.

Parameters

string $username
The username/identifier.

Returns

Cake\ORM\Query

authenticate()source abstract public

authenticate( Cake\Http\ServerRequest $request , Cake\Http\Response $response )

Authenticate a user based on the request information.

Parameters

Cake\Http\ServerRequest $request
Request to get authentication information from.
Cake\Http\Response $response
A response object that can have headers added.

Returns

mixed
Either false on failure, or an array of user data on success.

getUser()source public

getUser( Cake\Http\ServerRequest $request )

Get a user based on information in the request. Primarily used by stateless authentication systems like basic and digest auth.

Parameters

Cake\Http\ServerRequest $request
Request object.

Returns

mixed
Either false or an array of user information

implementedEvents()source public

implementedEvents( )

Returns a list of all events that this authenticate class will listen to.

An authenticate class can listen to following events fired by AuthComponent:

  • Auth.afterIdentify - Fired after a user has been identified using one of configured authenticate class. The callback function should have signature like afterIdentify(Event $event, array $user) when $user is the identified user record.

  • Auth.logout - Fired when AuthComponent::logout() is called. The callback function should have signature like logout(Event $event, array $user) where $user is the user about to be logged out.

Returns

array
List of events this class listens to. Defaults to [].

Implementation of

Cake\Event\EventListenerInterface::implementedEvents()

needsPasswordRehash()source public

needsPasswordRehash( )

Returns whether or not the password stored in the repository for the logged in user requires to be rehashed with another algorithm

Returns

boolean

passwordHasher()source public

passwordHasher( )

Return password hasher object

Returns

Cake\Auth\AbstractPasswordHasher
Password hasher instance

Throws

RuntimeException

If password hasher class not found or it does not extend AbstractPasswordHasher


unauthenticated()source public

unauthenticated( Cake\Http\ServerRequest $request , Cake\Http\Response $response )

Handle unauthenticated access attempt. In implementation valid return values can be:

  • Null - No action taken, AuthComponent should return appropriate response.
  • Cake\Http\Response - A response object, which will cause AuthComponent to simply return that response.

Parameters

Cake\Http\ServerRequest $request
A request object.
Cake\Http\Response $response
A response object.

Methods used from Cake\Core\InstanceConfigTrait

_configDelete()source protected

_configDelete( string $key )

Deletes a single config key.

Parameters

string $key
Key to delete.

Throws

if attempting to clobber existing config

_configRead()source protected

_configRead( string|null $key )

Reads a config key.

Parameters

string|null $key
Key to read.

Returns

mixed

_configWrite()source protected

_configWrite( string|array $key , mixed $value , boolean|string $merge = false )

Writes a config key.

Parameters

string|array $key

if attempting to clobber existing config

config()source public deprecated

config( string|array|null $key = null , mixed|null $value = null , boolean $merge = true )

Gets/Sets the config.

Usage

Reading the whole config:

$this->config();

Reading a specific value:

$this->config('key');

Reading a nested value:

$this->config('some.nested.key');

Setting a specific value:

$this->config('key', $value);

Cake\Core\Exception\Exception
When trying to set a key that is invalid.

configShallow()source public

configShallow( string|array $key , mixed|null $value = null )
