Available since version | 2.0 |
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
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.
Method Details
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.

}
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();
}
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().

$name | string |
The property name |
return | mixed |
The property value |
---|---|---|

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

throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($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.
public void __unset ( $name ) | ||
$name | string |

}
}
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().

{
return method_exists($this, 'get' . $name) || $checkVars && property_exists($this, $name);
}
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 |

}
Generates challenges upon authentication failure.
For example, some appropriate HTTP headers may be generated.
public void challenge ( $response ) | ||
$response | yii\web\Response |
public function challenge($response)
{
$response->getHeaders()->set('WWW-Authenticate', "Basic realm=\"{$this->realm}\"");
}
::class
instead.
Defined in: yii\base\BaseObject::className()

return | string |
The fully qualified name of this class. |
---|
public static function className()
{
return get_called_class();
}
Defined in: yii\base\ActionFilter::detach()
Detaches the behavior object from the component.
The default implementation will unset the $owner property and detach event handlers declared in events(). Make sure you call the parent implementation if you override this method.
public void detach ( ) |
public function detach()
{
if ($this->owner) {
$this->owner->off(Controller::EVENT_BEFORE_ACTION, [$this, 'beforeFilter']);
$this->owner->off(Controller::EVENT_AFTER_ACTION, [$this, 'afterFilter']);
$this->owner = null;
}
}
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). |
---|
public function events()
{
return [];
}
Defined in: yii\base\ActionFilter::getActionId()

{
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;
}
Defined in: yii\filters\auth\AuthMethod::handleFailure()
Handles authentication failure.
The implementation should normally throw UnauthorizedHttpException to indicate authentication failure.
public void handleFailure ( $response ) | ||
$response | yii\web\Response | |
throws | yii\web\UnauthorizedHttpException |
---|
public function handleFailure($response)
{
throw new UnauthorizedHttpException('Your request was made with invalid credentials.');
}
Defined in: yii\base\BaseObject::hasMethod()
Returns a value indicating whether a method is defined.
The default implementation is a call to php function method_exists()
.
You may override this method when you implemented the php magic method __call()
.
public boolean hasMethod ( $name ) | ||
$name | string |
The method name |
return | boolean |
Whether the method is defined |
---|
public function hasMethod($name)
{
return method_exists($this, $name);
}
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);
