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 Detail

__construct() ¶ 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.

_configDelete() ¶ protected

_configDelete(string $key): void

Delete a single config key

Parameters

string $key: Key to delete.

Returns

void

Throws

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

_configRead() ¶ protected

_configRead(string|null $key): mixed

Read a config variable

Parameters

string|null $key: Key to read.

Returns

mixed

_configWrite() ¶ protected

_configWrite(string|array $key, mixed $value, bool|string $merge = false): void

Write a config variable

Parameters

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

Returns

void

Throws

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

_findUser() ¶ protected

_findUser(string $username, string|null $password = null): bool|array

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: The password, if not provided password checking is skipped and result of find is returned.

Returns

bool|array

_query() ¶ protected

_query(string $username): Cake\ORM\Query

Get query object for fetching user from database.

Parameters

string $username: The username/identifier.

Returns

Cake\ORM\Query

authenticate() ¶ public

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

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

Parameters

Cake\Network\Request $request: The request to authenticate with.
Cake\Network\Response $response: The response to add headers to.

Returns

mixed

config() ¶ public

config(string|array|null $key = null, mixed|null $value = null, bool $merge = true): mixed

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

Returns

mixed

Throws

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

configShallow() ¶ public

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

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']);

Parameters

string|array $key: The key to set, or a complete array of configs.
mixed|null $value optional: The value to set.

Returns

$this

getUser() ¶ public

implementedEvents(): array

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

Handles an unauthenticated access attempt by sending appropriate login headers

Null - No action taken, AuthComponent should return appropriate response.
