Class FormAuthenticate

Form authentication adapter for AuthComponent.

Allows you to authenticate users based on form POST data. Usually, this is a login form that users enter information into.

Using Form auth

Load AuthComponent in your controller's initialize() and add 'Form' in 'authenticate' key

$this->loadComponent('Auth', [
    'authenticate' => [
        'Form' => [
            'fields' => ['username' => 'email', 'password' => 'passwd'],
            'finder' => 'auth',
        ]
    ]
]);

When configuring FormAuthenticate you can pass in config to which fields, model and finder are used. See BaseAuthenticate::$_defaultConfig for more information.

Method Summary

  • _checkFields() protected
    Checks the fields to ensure they are supplied.
  • 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.

Method Detail

_checkFields()source protected

_checkFields( Cake\Http\ServerRequest $request , array $fields )

Checks the fields to ensure they are supplied.

Cake\Http\ServerRequest $request
The request that contains login information.

The fields to be checked.

Returns

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

authenticate()source public

authenticate( Cake\Http\ServerRequest $request , Cake\Http\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\Http\ServerRequest $request
The request that contains login information.
Cake\Http\Response $response
Unused response object.

Returns

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

__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

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.
