_findUser() protected 

_findUser(string $username, ?string $password)

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

Returns

array|false

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

_query() protected 

_query(string $username)

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)

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

array|false

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

configShallow() public 

configShallow(mixed $key, mixed $value)

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 $key, mixed $default)

Returns the config.

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

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

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

string|null $key optional

The key to get or null for the whole config.

mixed $default optional

The return value when the key does not exist.

Returns

mixed

Configuration data at the named key or null if the key does not exist.

getConfigOrFail() public 

getConfigOrFail(string $key)

Returns the config for this specific key.

The config value for this key must exist, it can never be null.

Parameters

string $key

The key to get.

Returns

mixed

Configuration data at the named key

InvalidArgumentException

getTableLocator() public 

getTableLocator()

Gets the table locator.

Returns

\Cake\ORM\Locator\LocatorInterface

Request object.

Returns

array|false

Either false or an array of user information

implementedEvents() 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(EventInterface $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(EventInterface $event, array $user) where $user is the user about to be logged out.

Returns

array

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

setConfig() public 

setConfig(mixed $key, mixed $value, mixed $merge)

Sets the config.

Usage

Setting a specific value:

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

LocatorInterface instance.

Returns

$this

unauthenticated() public 

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

A request object.

\Cake\Http\Response $response

A response object.
