This project was forked from Filsh Original Project but the changes are not transparent, read [UPGRADE.md] to pass to the latest version.

Installation

The preferred way to install this extension is through composer.

Either run

php composer.phar require --prefer-dist tecnocen/yii2-oauth2-server "*"

or add

"tecnocen/yii2-oauth2-server": "~4.1"

to the require section of your composer.json.

Usage

To use this extension, simply add the following code in your application configuration as a new module:

    'bootstrap' => ['oauth2'],
    'modules'=>[
        // other modules ...
        'oauth2' => [
            'class' => 'tecnocen\oauth2server\Module',            
            'tokenParamName' => 'accessToken',
            'tokenAccessLifetime' => 3600 * 24,
            'storageMap' => [
                'user_credentials' => 'app\models\User',
            ],
            'grantTypes' => [
                'user_credentials' => [
                    'class' => 'OAuth2\GrantType\UserCredentials',
                ],
                'refresh_token' => [
                    'class' => 'OAuth2\GrantType\RefreshToken',
                    'always_issue_new_refresh_token' => true
                ]
            ]
        ]
    ],

Bootstrap will initialize translation and add the required url rules to Yii::$app->urlManager.

JWT tokens

There is no JWT token support on this fork, feel free to submit a (pull request)[https://github.com/tecnocen-com/yii2-oauth2-server/pulls] to enable this functionality.

UserCredentialsInterface

The class passed to Yii::$app->user->identityClass must implement the interface \OAuth2\Storage\UserCredentialsInterface, to store oauth2 credentials in user table.

use Yii;

class User extends common\models\User
    implements \OAuth2\Storage\UserCredentialsInterface
{

    /**
     * Implemented for Oauth2 Interface
     */
    public static function findIdentityByAccessToken($token, $type = null)
    {
        /** @var \tecnocen\oauth2server\Module $module */
        $module = Yii::$app->getModule('oauth2');
        $token = $module->getServer()->getResourceController()->getToken();
        return !empty($token['user_id'])
                    ? static::findIdentity($token['user_id'])
                    : null;
    }

    /**
     * Implemented for Oauth2 Interface
     */
    public function checkUserCredentials($username, $password)
    {
        $user = static::findByUsername($username);
        if (empty($user)) {
            return false;
        }
        return $user->validatePassword($password);
    }

    /**
     * Implemented for Oauth2 Interface
     */
    public function getUserDetails($username)
    {
        $user = static::findByUsername($username);
        return ['user_id' => $user->getId()];
    }
}

Migrations

The next step is to run migrations

yii migrate all -p=@tecnocen/oauth2server/migrations/tables
yii fixture "*" -n=tecnocen/oauth2server/fixtures

The first commando create the OAuth2 database scheme. The second command insert test client credentials testclient:testpass for http://fake/.

Controllers

To support authentication by access token. Simply add the behaviors for your controller or module.

use yii\helpers\ArrayHelper;
use yii\filters\auth\HttpBearerAuth;
use yii\filters\auth\QueryParamAuth;
use tecnocen\oauth2server\filters\auth\CompositeAuth;

class Controller extends \yii\rest\Controller
{
    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return ArrayHelper::merge(parent::behaviors(), [
            'authenticator' => [
                'class' => CompositeAuth::class,
                'authMethods' => [
                    ['class' => HttpBearerAuth::class],
                    [
                        'class' => QueryParamAuth::class,
                        'tokenParam' => 'accessToken',
                    ],
                ]
            ],
        ]);
    }
}

The code above is the same as the default implementation which can be simplified as:

use yii\helpers\ArrayHelper;
use tecnocen\oauth2server\filters\auth\CompositeAuth;

class Controller extends \yii\rest\Controller
{
    /**
     * @inheritdoc
     */
    public function behaviors()
    {
        return ArrayHelper::merge(parent::behaviors(), [
            'authenticator' => CompositeAuth::class,
        ]);
    }
}

Scopes

The property tecnocen\oauth2server\filters\auth\CompositeAuth::$actionScopes set which actions require specific scopes. If those scopes are not meet the action wont be executed, and the server will reply with an HTTP Status Code 403.

public function behaviors()
{
    return ArrayHelper::merge(parent::behaviors(), [
        'authenticator' => [
            'class' => CompositeAuth::class,
            'actionScopes' => [
                'create' => 'default create',
                'update' => 'default edit',
                '*' => 'default', // wildcards are allowed
            ]
        ],,
    ]);
}

Automatically Revoke Tokens

Sometimes its neccessary to revoke a token on each request to prevent the request from being triggered twice.

To enable this functionality you need to implement tecnocen\oauth2server\RevokeAccessTokenInterface in the class used to identify the authenticated user.

use OAuth2\Storage\UserCredentialsInterface;
use tecnocen\oauth2server\RevokeAccessTokenInterface;
use tecnocen\oauth2server\RevokeAccessTokenTrait;

class User extend \yii\db\ActiveRecord implement
    UserCredentialsInterface,
    RevokeAccessTokenInterface
{
    use RevokeAccessTokenTrait; // optional, trait with default implementation.
    
    // rest of the class.
}

Then use the previous class as configuration for Yii::$app->user->identityClass

Attaching the action filter tecnocen\oauth2server\filters\RevokeAccessToken allows to configure the actions to automatically revoke the access token.

public function behaviors()
{
    return [
        'revokeToken' => [
            'class' => \tecnocen\oauth2server\filters\RevokeAccessToken::class,
            // optional only revoke the token if it has any of the following
            // scopes. if not defined it will always revoke the token.
            'scopes' => ['author', 'seller'],
            // optional whether or not revoke all tokens or just the active one
            'revokeAll' => true,
            // optional if non authenticated users are permited.
            'allowGuests' => true,
            // which actions this behavior applies to.
            'only' => ['create', 'update'],
        ]
    ];
}

Generate Token with JS

To get access token (js example):

var url = window.location.host + "/oauth2/token";
var data = {
    'grant_type':'password',
    'username':'<some login from your user table>',
    'password':'<real pass>',
    'client_id':'testclient',
    'client_secret':'testpass'
};
//ajax POST `data` to `url` here
//
