Method Detail

__construct() ¶ 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.

_configDelete() ¶ protected

_configDelete(string $key): void

Deletes a single config key.

Parameters

string $key: Key to delete.

Returns

void

Throws

Cake\Core\Exception\Exception
if attempting to clobber existing config

_configRead() ¶ protected

_configRead(string|null $key): mixed

Reads a config key.

Cake\Core\Exception\Exception
if attempting to clobber existing config

_findUser() ¶ protected

_findUser(string $username, string|null $password = null): bool|array

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

Returns

bool|array

_query() ¶ protected

_query(string $username): Cake\ORM\Query

Get query object for fetching user from database.

Parameters

string $username: The username/identifier.

Returns

Cake\ORM\Query

authenticate() ¶ abstract public

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

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

config() ¶ public

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

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);

Setting a nested value:

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

Updating multiple config settings at the same time:

$this->config(['one' => 'value', 'another' => 'value']);

Parameters

string|array|null $key optional: The key to get/set, or a complete array of configs.
mixed|null $value optional: The value to set.
bool $merge optional: Whether to recursively merge or overwrite existing config, defaults to true.

Returns

mixed

Throws

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

configShallow() ¶ public

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

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

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

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key: The key to set, or a complete array of configs.
mixed|null $value optional: The value to set.

Returns

$this

getConfig() ¶ public

getConfig(string|null $key = null): mixed

Returns the config.

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

Parameters

string|null $key optional: The key to get or null for the whole config.

Returns

mixed

getUser() ¶ public

getUser(Cake\Http\ServerRequest $request): mixed

Parameters

Cake\Http\ServerRequest $request: Request object.

Returns

mixed

implementedEvents() ¶ public

implementedEvents(): array

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

needsPasswordRehash() ¶ public

needsPasswordRehash(): bool

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

Returns

bool

passwordHasher() ¶ public

passwordHasher(): Cake\Auth\AbstractPasswordHasher

Return password hasher object

Returns

Cake\Auth\AbstractPasswordHasher

Throws

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

setConfig() ¶ public

setConfig(string|array $key, mixed|null $value = null, bool $merge = true): $this

Sets the config.

Usage

Setting a specific value:

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

Setting a nested value:

$this->setConfig('some.nested.key', $value);

$this->setConfig(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key: The key to set, or a complete array of configs.
mixed|null $value optional: The value to set.
bool $merge optional: Whether to recursively merge or overwrite existing config, defaults to true.

$this

Throws

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

unauthenticated() ¶ public

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

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.

Returns

void
