Inheritance	yii\authclient\OpenId » yii\authclient\BaseClient » yii\base\Component » yii\base\BaseObject
Implements	yii\authclient\ClientInterface, yii\base\Configurable
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2-authclient/blob/master/OpenId.php

OpenId provides a simple interface for OpenID (1.1 and 2.0) authentication.

Supports Yadis and HTML discovery.

Usage:

use yii\authclient\OpenId;

$client = new OpenId();
$client->authUrl = 'https://open.id.provider.url'; // Setup provider endpoint
$url = $client->buildAuthUrl(); // Get authentication URL
return Yii::$app->getResponse()->redirect($url); // Redirect to authentication URL
// After user returns at our site:
if ($client->validate()) { // validate response
    $userAttributes = $client->getUserAttributes(); // get account info
    ...
}

AX and SREG extensions are supported. To use them, specify $requiredAttributes and/or $optionalAttributes.
