Class BasicAuthenticate

Basic Authentication adapter for AuthComponent.

Provides Basic HTTP authentication support for AuthComponent. Basic Auth will authenticate users against the configured userModel and verify the username and passwords match.

Using Basic auth

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

$this->loadComponent('Auth', [
     'authenticate' => ['Basic']
     'storage' => 'Memory',
     'unauthorizedRedirect' => false,
 ]);

You should set storage to Memory to prevent CakePHP from sending a session cookie to the client.

You should set unauthorizedRedirect to false. This causes AuthComponent to throw a ForbiddenException exception instead of redirecting to another page.

Since HTTP Basic Authentication is stateless you don't need call setUser() in your controller. The user credentials will be checked on each request. If valid credentials are not provided, required authentication headers will be sent by this authentication provider which triggers the login dialog in the browser/client.

Method Summary

  • Authenticate a user using HTTP auth. Will use the configured User model and attempt a login using HTTP auth.

  • getUser() public
    Get a user based on information in the request. Used by cookie-less auth for stateless clients.
  • Generate the login headers
  • Handles an unauthenticated access attempt by sending appropriate login headers

__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.

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

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
