README

Set of simple tools that helps to build API based on alegz/yii2-oauth2-server package.

Installation

Via command line:

composer require the-real-start/yii2-oauth2-server-tools

Or add lime to composer.json requirement section:

"require": {
    ...
    "the-real-start/yii2-oauth2-server-tools": "*"
    ...
  }

Usage

Package namepsace: TRS\yii2\oauth2server\tools

Package provides 5 classes for setting up oauth2-server:

• Abstract class AppIdentity
• Abstract class User
• Class ErrorHandler
• Class AccessRules
• Class JsonHttpException

AppIdentity

Abstract class for client credentials grant_type (see https://tools.ietf.org/html/rfc6749 for details).

You should declare getIsPublic method for you version of AppIdentity class. See example below:

<?php

namespace common\components;

use common\components\enums\Scope;
use TRS\yii2\oauth2server\tools\oauth2\AppIdentity as BaseAppIdentity

class AppIdentity extends BaseAppIdentity
{
    /**
     * @inheritdoc
     */
    abstract public function isPublicClient($client_id){
       $app = self::findByClientId($client_id);
       
       return !!$app && $app->scope == Scope::_PUBLIC;
    }
} 

Example with setting up module of yii2-oauth2-server:

modules'             => [
...
   'oauth2' => [
    'class'               => \filsh\yii2\oauth2server\Module::className(),
    ...
    'storageMap'          => [
        ...
        'client_credentials' => \common\components\AppIdentity::class,
    ],
    ...
],
...
],

User

This abstract class extends yii\web\User adds getIsPublic method and changes logic around logging user out.

This class requires to declare method getIsPublic for User

Example of class:

<?php

namespace common\components;

use common\enums\Scope;
use TRS\yii2\oauth2server\tools\oauth2\User as BaseUser;

class User extends BaseUser
{
    /**
     * @ingeritdoc
     */
    public function getIsPublic()
    {
        /** @var \common\models\User $identity */
        $identity = $this->getIdentity(false);
        
        return ( $identity->scope == Scope::_PUBLIC );
    }
}

Setting up example:

'components'          => [
    ...
    'user'                 => [
        'class'           => \common\components\User::className(),
        'identityClass'   => \common\models\User::className(),
        'enableAutoLogin' => true,
    ],
    ...
],

ErrorHandler

Simple error handler that were designed to be used with API.

Setup example in yii2 main.php config file in components section:

...
'errorHandler'         => [
    'class' => \v1\components\oauth2\rest\ErrorHandler::className(),
],
...

AccessRules

Extended version of yii2 AccessRule. Adds support of user scope filtering.

Example of rule

 public function accessRules()
    {
        return [
            [
                'allow'   => true,
                'roles'   => [ '@' ],
                'actions' => [ 'registration', 'send-recovery-email', 'reset-password', 'check-reset-token' ],
                'scopes'  => [ Scope::_PUBLIC ],
            ],
        ];
    }

Setup example:

public function behaviors()
    {
     $behaviors = parent::behaviors();
     ...
     $behaviors = ArrayHelper::merge(
            $behaviors,
            [
                ...
                'access'            => [
                                         'class'      => AccessControl::className(),
                                         'rules'      => $this->accessRules(),
                                         'ruleConfig' => ['class' => AccessRule::class],
                ],
                ...
            ]
        );

        return $behaviors;
    }

In this and previous examples accessRules were declared as abstract method in base controller.

JsonHttpException

It's simple wrapper over HTTPException that can accept array as message.

Array is converted to json.

Designed to use with ErrorHandler but you are free to adopt it to your tools.

Small example

/** @var array */
$errors = $model->getErrors();

throw new JsonHttpException(400, $errors);
