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 config

public $components = [
     'Auth' => [
         'authenticate' => ['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.

Method Summary

authenticate() public

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.
loginHeaders() public
Generate the login headers
unauthenticated() public
Handles an unauthenticated access attempt by sending appropriate login headers

Method Detail

Either false or an array of user information

Overrides

Cake\Auth\BaseAuthenticate::getUser()

loginHeaders()source public

loginHeaders( Cake\Http\ServerRequest $request )

Generate the login headers

Parameters

Cake\Http\ServerRequest $request: Request object.

Returns

string
Headers for logging in.

unauthenticated()source public

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

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.

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

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

_configDelete()source protected

_configDelete( string $key )

Deletes a single config key.

Parameters

string $key: Key to delete.

Throws

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

_configRead()source protected

_configRead( string|null $key )

Reads a config key.

Parameters

string|null $key: Key to read.

Returns

mixed

_configWrite()source protected

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

Writes a config key.

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

config()source public

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

Gets/Sets the config.

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']);
