Source Code https://github.com/yiisoft/yii2/blob/master/framework/filters/auth/HttpBasicAuth.php

HttpBasicAuth is an action filter that supports the HTTP Basic authentication method.

You may use HttpBasicAuth by attaching it as a behavior to a controller or module, like the following:

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

The default implementation of HttpBasicAuth uses the loginByAccessToken() method of the user application component and only passes the user name. This implementation is used for authenticating API clients.

If you want to authenticate users using username and password, you should provide the $auth function for example like the following:

public function behaviors()
{
    return [
        'basicAuth' => [
            'class' => \yii\filters\auth\HttpBasicAuth::class,
            'auth' => function ($username, $password) {
                $user = User::find()->where(['username' => $username])->one();
                if ($user && $user->validatePassword($password)) {
                    return $user;
                }
                return null;
            },
        ],
    ];
}

Tip: In case authentication does not work like expected, make sure your web server passes username and password to $_SERVER['PHP_AUTH_USER'] and $_SERVER['PHP_AUTH_PW'] variables. If you are using Apache with PHP-CGI, you might need to add this line to your .htaccess file: RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization},L]

Property Details

Hide inherited properties

$auth public property

A PHP callable that will authenticate the user with the HTTP basic auth information. The callable receives a username and a password as its parameters. It should return an identity object that matches the username and password. Null should be returned if there is no such identity. The callable will be called only if current user is not authenticated.

The following code is a typical implementation of this callable:

function ($username, $password) {
    return \app\models\User::findOne([
        'username' => $username,
        'password' => $password,
    ]);
}

If this property is not set, the username information will be considered as an access token while the password information will be ignored. The yii\web\User::loginByAccessToken() method will be called to authenticate and login the user.

public callable|null $auth = null
$realm public property

The HTTP authentication realm

public string $realm = 'api'

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

}
__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

 

                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

}
__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).

    }
}
__unset() public method

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

Sets an object property to null.

    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.

        $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).

        $id = $action->getUniqueId();
        if ($mid !== '' && strpos($id, $mid) === 0) {
            $id = substr($id, strlen($mid) + 1);

        $id = $action->id;
    }
    return $id;
}
