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.
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.
array
Runtime config
bool
Whether the config property has already been configured with defaults
array
Default config for this object.
bool
Whether or not the user authenticated by this class requires their password to be rehashed with another algorithm.

\Cake\ORM\Locator\LocatorInterface|null
Table locator instance
Authenticate a user using HTTP auth. Will use the configured User model and attempt a login using HTTP auth.
Merge provided config with existing config. Unlike config()
which does a recursive merge for nested keys, this method does a simple merge.
Get a user based on information in the request. Used by cookie-less auth for stateless clients.
Returns a list of all events that this authenticate class will listen to.
Returns whether or not the password stored in the repository for the logged in user requires to be rehashed with another algorithm
Handles an unauthenticated access attempt by sending appropriate login headers

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 The password, if not provided password checking is skipped and result of find is returned.
array|false
Either false on failure, or an array of user data.

\Cake\ORM\Query
authenticate(\Cake\Http\ServerRequest $request, \Cake\Http\Response $response)
Authenticate a user using HTTP auth. Will use the configured User model and attempt a login using HTTP auth.
\Cake\Http\ServerRequest

\Cake\Http\Response
$response The response to add headers to.
array|false
Either false on failure, or an array of user data on success.
configShallow(mixed $key, mixed $value)
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->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);
string|array
$key The key to set, or a complete array of configs.
mixed|null
$value optional The value to set.
$this
getConfig(?string $key, mixed $default)
Returns the config.
Reading the whole config:
$this->getConfig();
Reading a specific value:
$this->getConfig('key');
Reading a nested value:
$this->getConfig('some.nested.key');
Reading with default value:
$this->getConfig('some-key', 'default-value');
string|null
$key optional The key to get or null for the whole config.
mixed
$default optional The return value when the key does not exist.
mixed
Configuration data at the named key or null if the key does not exist.
getConfigOrFail(string $key)
Returns the config for this specific key.
The config value for this key must exist, it can never be null.
string
$key The key to get.
mixed
Configuration data at the named key
InvalidArgumentException
getTableLocator()
Gets the table locator.
\Cake\ORM\Locator\LocatorInterface
getUser(\Cake\Http\ServerRequest $request)
Get a user based on information in the request. Used by cookie-less auth for stateless clients.
\Cake\Http\ServerRequest
$request Request object.
array|false
Either false or an array of user information
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(EventInterface $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(EventInterface $event, array $user)
where $user
is the user about to be logged out.
array
List of events this class listens to. Defaults to []
.
loginHeaders(\Cake\Http\ServerRequest $request)
Generate the login headers
\Cake\Http\ServerRequest
$request Request object.
