# Class yii\filters\auth\CompositeAuth

Inheritance | yii\filters\auth\CompositeAuth » yii\filters\auth\AuthMethod » yii\base\ActionFilter » yii\base\Behavior » yii\base\BaseObject
Implements | yii\base\Configurable, yii\filters\auth\AuthInterface
Available since version | 2.0
Source Code | https://github.com/yiisoft/yii2/blob/master/framework/filters/auth/CompositeAuth.php

CompositeAuth is an action filter that supports multiple authentication methods at the same time.

The authentication methods contained by CompositeAuth are configured via $authMethods, which is a list of supported authentication class configurations.

The following example shows how to support three authentication methods:

    public function behaviors()
    {
        return [
            'compositeAuth' => [
                'class' => \yii\filters\auth\CompositeAuth::class,
                'authMethods' => [
                    \yii\filters\auth\HttpBasicAuth::class,
                    \yii\filters\auth\QueryParamAuth::class,
                ],
            ],
        ];
    }

## Property Details

Hide inherited properties

$authMethods public property

The supported authentication methods. This property should take a list of supported authentication methods, each represented by an authentication class or configuration.

If this property is empty, no authentication will be performed.

Note that an auth method class must implement the yii\filters\auth\AuthInterface interface.

public array $authMethods = []

## Method Details

Hide inherited methods

__call() public method

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name | string | The method name
$params | array | Method parameters
return | mixed | The method return value
throws | yii\base\UnknownMethodException | when calling unknown method

Source code

                    public function __call($name, $params)
    {
        throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
    }

__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

- Initializes the object with the given configuration `$config`.
- Call init().

If this method is overridden in a child class, it is recommended that

- the last parameter of the constructor is a configuration array, like `$config` here.
- call the parent implementation at the end of the constructor.

public void __construct ( $config = [] )
$config | array | Name-value pairs that will be used to initialize the object properties

Source code

                    public function __construct($config = [])
    {
        if (!empty($config)) {
            Yii::configure($this, $config);
        }
        $this->init();
    }

__get() public method

Defined in: yii\base\BaseObject::__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `$value = $object->property;`.

See also __set().

public mixed __get ( $name )
$name | string | The property name
return | mixed | The property value
throws | yii\base\UnknownPropertyException | if the property is not defined
throws | yii\base\InvalidCallException | if the property is write-only

Source code

                    public function __get($name)
    {
        $getter = 'get' . $name;
        if (method_exists($this, $getter)) {
            return $this->$getter();
        } elseif (method_exists($this, 'set' . $name)) {
            throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
        }
        throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
    }

__isset() public method

Defined in: yii\base\BaseObject::__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `isset($object->property)`.

Note that if the property is not defined, false will be returned.

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name | string | The property name or the event name
return | boolean | Whether the named property is set (not null).

Source code

                    public function __isset($name)
    {
        $getter = 'get' . $name;
        if (method_exists($this, $getter)) {
            return $this->$getter() !== null;
        }
        return false;
    }

__set() public method

Defined in: yii\base\BaseObject::__set()

Sets value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `$object->property = $value;`.

See also __get().

public void __set ( $name, $value )
$name | string | The property name or the event name
$value | mixed | The property value
throws | yii\base\UnknownPropertyException | if the property is not defined
throws | yii\base\InvalidCallException | if the property is read-only

Source code

                    public function __set($name, $value)
    {
        $setter = 'set' . $name;
        if (method_exists($this, $setter)) {
            $this->$setter($value);
        } elseif (method_exists($this, 'get' . $name)) {
            throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
        } else {
            throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
        }
    }

__unset() public method

Defined in: yii\base\BaseObject::__unset()

Sets an object property to null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing `unset($object->property)`.

Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.

See also https://www.php.net/manual/en/function.unset.php.

public void __unset ( $name )
$name | string | The property name
throws | yii\base\InvalidCallException | if the property is read only.

        $event->result = $this->afterAction($event->action, $event->result);
        $this->owner->off(Controller::EVENT_AFTER_ACTION, [$this, 'afterFilter']);
    }

attach() public method

Defined in: yii\base\ActionFilter::attach()

Attaches the behavior object to the component.

The default implementation will set the $owner property and attach event handlers as declared in events(). Make sure you call the parent implementation if you override this method.

public void attach ( $owner )
$owner | yii\base\Component | The component that this behavior is to be attached to.

Source code

                    public function attach($owner)

            }
        }
        return null;
    }

public boolean beforeAction ( $action )
$action | yii\base\Action | The action to be executed.
return | boolean | Whether the action should continue to be executed.

Source code

                    public function beforeAction($action)
    {
        return empty($this->authMethods) ? true : parent::beforeAction($action);
    }

        }
    }

canGetProperty() public method

Defined in: yii\base\BaseObject::canGetProperty()

Returns a value indicating whether a property can be read.

A property is readable if:

- the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when `$checkVars` is true);

See also canSetProperty().

public boolean canGetProperty ( $name, $checkVars = true )
$name | string | The property name
$checkVars | boolean | Whether to treat member variables as properties
return | boolean | Whether the property can be read

Source code

                    public function canGetProperty($name, $checkVars = true)
    {
        return method_exists($this, 'get' . $name) || $checkVars && property_exists($this, $name);
    }

canSetProperty() public method

Defined in: yii\base\BaseObject::canSetProperty()

Returns a value indicating whether a property can be set.

A property is writable if:

- the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when `$checkVars` is true);

See also canGetProperty().

public boolean canSetProperty ( $name, $checkVars = true )
$name | string | The property name
$checkVars | boolean | Whether to treat member variables as properties
return | boolean | Whether the property can be written

Source code

                    public function canSetProperty($name, $checkVars = true)
    {
        return method_exists($this, 'set' . $name) || $checkVars && property_exists($this, $name);
    }

challenge() public method

Generates challenges upon authentication failure.

For example, some appropriate HTTP headers may be generated.

public void challenge ( $response )
$response | yii\web\Response |

Source code

                    public function challenge($response)
    {
        foreach ($this->authMethods as $method) {
            /** @var AuthInterface $method */
            $method->challenge($response);
        }
    }

className() public static method
Deprecated since 2.0.14. On PHP >=5.5, use `::class` instead.

Defined in: yii\base\BaseObject::className()

Returns the fully qualified name of this class.

public static string className ( )
return | string | The fully qualified name of this class.

Source code

                    public static function className()
    {
        return get_called_class();
    }

detach() public method

Defined in: yii\base\ActionFilter::detach()

Detaches the behavior object from the component.

The default implementation will unset the $owner property and detach event handlers declared in events(). Make sure you call the parent implementation if you override this method.

public void detach ( )

Source code

                    public function detach()
    {
        if ($this->owner) {
            $this->owner->off(Controller::EVENT_BEFORE_ACTION, [$this, 'beforeFilter']);
            $this->owner->off(Controller::EVENT_AFTER_ACTION, [$this, 'afterFilter']);
            $this->owner = null;
        }
    }

events() public method

Defined in: yii\base\Behavior::events()

Declares event handlers for the $owner's events.

Child classes may override this method to declare what PHP callbacks should be attached to the events of the $owner component.

The callbacks will be attached to the $owner's events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.

The callbacks can be any of the following:

- method in this behavior: `'handleClick'`, equivalent to `[$this, 'handleClick']`
- object method: `[$object, 'handleClick']`
- static method: `['Page', 'handleClick']`
- anonymous function: `function ($event) { ... }`

The following is an example:

    [
        Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
        Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
    ]

public array events ( )
return | array | Events (array keys) and the corresponding event handler methods (array values).

Source code

                    public function events()
    {
        return [];
    }

getActionId() protected method (available since version 2.0.7)

                    protected function getActionId($action)
    {
        if ($this->owner instanceof Module) {
            $mid = $this->owner->getUniqueId();
            $id = $action->getUniqueId();
            if ($mid !== '' && strpos($id, $mid) === 0) {
                $id = substr($id, strlen($mid) + 1);
            }
        } else {
            $id = $action->id;
        }
        return $id;
    }

handleFailure() public method

Defined in: yii\filters\auth\AuthMethod::handleFailure()

Handles authentication failure.

The implementation should normally throw UnauthorizedHttpException to indicate authentication failure.

public void handleFailure ( $response )
$response | yii\web\Response |
throws | yii\web\UnauthorizedHttpException |

Source code

                    public function handleFailure($response)

        throw new UnauthorizedHttpException('Your request was made with invalid credentials.');
    }

hasMethod() public method

Defined in: yii\base\BaseObject::hasMethod()

        return method_exists($this, $name);
    }

hasProperty() public method

Defined in: yii\base\BaseObject::hasProperty()

Returns a value indicating whether a property is defined.

A property is defined if:

- the class has a getter or setter method associated with the specified name (in this case, property name is case-insensitive);
- the class has a member variable with the specified name (when `$checkVars` is true);

See also:

- canGetProperty()
- canSetProperty()

public boolean hasProperty ( $name, $checkVars = true )
$name | string | The property name
$checkVars | boolean | Whether to treat member variables as properties

        $id = $this->getActionId($action);
        if (empty($this->only)) {
            $onlyMatch = true;
        } else {
            $onlyMatch = false;
            foreach ($this->only as $pattern) {
                if (StringHelper::matchWildcard($pattern, $id)) {
                    $onlyMatch = true;
                    break;
