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

In your controller's components array, add auth + the required settings.

public $components = array(
    'Auth' => array(
        'authenticate' => array('Basic')
    )
);

You should also set AuthComponent::$sessionKey = false; in your AppController's beforeFilter() to prevent CakePHP from sending a session cookie to the client.

Since HTTP Basic Authentication is stateless you don't need a login() action 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.

You may also want to use $this->Auth->unauthorizedRedirect = false;. By default, unauthorized users are redirected to the referrer URL, AuthComponent::$loginAction, or '/'. If unauthorizedRedirect is set to false, a ForbiddenException exception is thrown instead of redirecting.

_findUser()source protected

_findUser( string|array $username , string $password null )

Find a user record using the standard options.

The $username parameter can be a (string)username or an array containing conditions for Model::find('first'). If the $password param is not provided the password field will be present in returned array.

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|array $username: The username/identifier, or an array of find conditions.
string $password optional null: The password, only used if $username param is string.

Returns

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

_password()source protected

_password( string $password )

Hash the plain text password so that it matches the hashed/encrypted password in the datasource.

Deprecated

3.0.0 Since 2.4. Use a PasswordHasher class instead.

Parameters

string $password: The plain text password.

Returns

string
The hashed form of the password.

implementedEvents()source public

implementedEvents( )

Implemented events

Returns

array
of events => callbacks.

Implementation of

logout()source public

logout( array $user )

Allows you to hook into AuthComponent::logout(), and implement specialized logout behavior.

passwordHasher()source public

passwordHasher( )

Return password hasher object

Returns

AbstractPasswordHasher
