Class FormAuthenticate

An authentication adapter for AuthComponent. Provides the ability to authenticate using POST data. Can be used by configuring AuthComponent to use it via the AuthComponent::$authenticate config.

$this->Auth->authenticate = [
    'Form' => [
        'scope' => ['Users.active' => 1]
    ]
]

When configuring FormAuthenticate you can pass in config to which fields, model and additional conditions are used. See FormAuthenticate::$_config for more information.

Method Detail

_checkFieldssource protected

_checkFields( Cake\Network\Request $request , array $fields )

Checks the fields to ensure they are supplied.

Parameters

Cake\Network\Request $request
The request that contains login information.
array $fields
The fields to be checked.

Returns

boolean
False if the fields have not been supplied. True if they exist.

authenticatesource public

authenticate( Cake\Network\Request $request , Cake\Network\Response $response )

Authenticates the identity contained in a request. Will use the config.userModel, and config.fields to find POST data that is used to find a matching record in the config.userModel. Will return false if there is no post data, either username or password is missing, or if the scope conditions have not been met.

Parameters

Cake\Network\Request $request
The request that contains login information.
Cake\Network\Response $response
Unused response object.

Returns

mixed
False on login failure. An array of User data on success.

__constructsource 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.

_findUsersource 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.

_querysource protected

_query( string $username )

Get query object for fetching user from database.

Parameters

string $username
The username/identifier.

Returns

Cake\ORM\Query
\Cake\ORM\Query

getUsersource public

getUser( Cake\Network\Request $request )

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

Parameters

Cake\Network\Request $request
Request object.

Returns

mixed
Either false or an array of user information

implementedEventssource 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()

needsPasswordRehashsource 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
bool

passwordHashersource 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

unauthenticatedsource public

unauthenticated( Cake\Network\Request $request , Cake\Network\Response $response )

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

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

Parameters

Cake\Network\Request $request
A request object.
Cake\Network\Response $response
A response object.

Methods used from Cake\Core\InstanceConfigTrait

_configDeletesource protected

_configDelete( string $key )

Delete a single config key

Parameters

string $key
Key to delete.

Throws

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

_configReadsource protected

_configRead( string|null $key )

Read a config variable

Parameters

mixed

_configWritesource protected

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

Write a config variable

Parameters

string|array $key
Key to write to.
mixed $value
Value to write.
boolean|string $merge optional false
True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.

Throws

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

configsource public

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

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

Returns

mixed
Config value being read, or the object itself on write operations.

Throws

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

configShallowsource public

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

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->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']);
