Class FormAuthenticate

An authentication adapter for AuthComponent. Provides the ability to authenticate using POST data. Can be used by configuring AuthComponent to use it via the AuthComponent::$authenticate config.

 $this->Auth->authenticate = [
     'Form' => [
         'finder' => ['auth' => ['some_finder_option' => 'some_value']]
     ]
 ]

When configuring FormAuthenticate you can pass in config to which fields, model and additional conditions are used. See FormAuthenticate::$_config for more information.

Namespace: Cake\Auth
See: \Cake\Controller\Component\AuthComponent::$authenticate

Property Summary

  • $_config protected
    array

    Runtime config

    Cake\Auth\AbstractPasswordHasher

    Password hasher instance.

  • $_registry protected
    Cake\Controller\ComponentRegistry

    A Component registry, used to get more components.

Method Summary

  • __construct() public

    Constructor

  • authenticate() public

    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.

Delete a single config key

Parameters
string $key

Key to delete.

Returns
void
Throws

_configRead() ¶ protected

_configRead(string|null $key): mixed

Read a config variable

Parameters
string|null $key

Key to read.

Returns
mixed

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

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\Network\Request $request

The request that contains login information.

Cake\Network\Response $response

Unused response object.

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

  • 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

needsPasswordRehash() ¶ public

needsPasswordRehash(): bool

Returns whether or not the password stored in the repository for the logged in user requires to be rehashed with another algorithm

RuntimeException
If password hasher class not found or it does not extend AbstractPasswordHasher

unauthenticated() ¶ public

unauthenticated(Cake\Network\Request $request, Cake\Network\Response $response): void

Handle unauthenticated access attempt. In implementation valid return values can be:

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