Yii 2 REST API Template

Yii2 REST API Template

This is a a REST API TEMPLATE with Yii2. This template use Yii2-Micro approach so it will be lightweight and easy to deploy.

Installation

The preferred way to install this template is through composer.

Either run

composer create-project --prefer-dist hoaaah/yii2-rest-api-template [app_name]

Setup your database configuration from config/db.php. Create your database because this template will not create it for you :)

<?php
return [
    'components' => [
        'db' => [
            'class' => 'yii\db\Connection',
            'dsn' => 'mysql:host=localhost;dbname=your_db_name',
            'username' => 'root',
            'password' => '',
            'charset' => 'utf8',
        ],
    ],
];

Then run migration to create table in selected database.

yii migrate

Directory Structure

Since this template use MicroFramework approach, directory structure might be a little bit different from Yii2.

  config/             contains application configurations
  controllers/        contains Web controller classes
  migration/          contains list of your migration files
  models/             contains model classes
  modules/            contains your rest-api versioning (based on modules)
  vendor/             contains dependent 3rd-party packages
  web/                contains the entry script and Web resources

This template use modules as versioning pattern. Every version of API saved in a module. This template already have v1 module, so it means if consumer want to use v1 API, it can access https://your-api-url/v1/endpoint.

API Scenario

Supported Authentication

This template support 3 most used authentication. (Actually it's not me who make it, Yii2 already support it all :D ).

1. HTTP Basic Auth: the access token is sent as the username. This should only be used when an access token can be safely stored on the API consumer side. For example, the API consumer is a program running on a server.
2. Query parameter: the access token is sent as a query parameter in the API URL, e.g., https://example.com/users?access-token=xxxxxxxx. Because most Web servers will keep query parameters in server logs, this approach should be mainly used to serve JSONP requests which cannot use HTTP headers to send access tokens.
3. OAuth 2: the access token is obtained by the consumer from an authorization server and sent to the API server via HTTP Bearer Tokens, according to the OAuth2 protocol.

Global Configuration of AuthMethods and RateLimiter

This template provide global configuration to set your application supported authMethods. You can find global configuration from app\config\params.php. Set your supported authMethods and RateLimiter from this file.

return [
    'useHttpBasicAuth' => true,
    'useHttpBearerAuth' => true,
    'useQueryParamAuth' => true,
    'useRateLimiter' => false,
];

Example use in behaviors looks like this

use app\helpers\BehaviorsFromParamsHelper;
use yii\rest\ActiveController;

class PostController extends ActiveController
{
    public $modelClass = 'app\models\Post';

    public function behaviors()
    {
        $behaviors = parent::behaviors();
        $behaviors = BehaviorsFromParamsHelper::behaviors($behaviors);
        // if you need other behaviors method use like this
        // $behaviors['otherMethods'] = $value;
        return $behaviors;
    }
}

Ratelimiter

To enable your ratelimiter configuration, please follow official guide from Yii documentation.

Auth Scenario

This template already have basic endpoint that you can use to start your REST-API. Such as:

Access Token Management

This application manage token via access_token table. Access Token have certain expiration based on $tokenExpiration value. Default Token Expiration are in seconds.

public $tokenExpiration = 60 * 24 * 365; // in seconds

In certain case you want to make a token expire before given tokenExpiration. Use expireThisToken() method to achieve it.

$accessToken = AccessToken::findOne(['token' => $token]);
$accessToken->expireThisToken();

Or you want to make all tokens from certain user expire, use makeAllUserTokenExpiredByUserId($userId) method to achieve it.

$user = Yii::$app->user->identity; // or User::findOne($id)
AccessToken::makeAllUserTokenExpiredByUserId($user->id);

API versioning

This template give you versioning scenario based on module application. In Yii2 a module are self-contained software units that consist of model, views, controllers and other supporting components. This template already have v1 module, it means all of endpoint for API v1 created in this module. When you publish a new API version (that break backward compatibility / BBC), you can create a new module. For more information create a module, you can visit this Yii2 Guide on Creating Module.

TODO

Feel free to contribute if you have any idea.

• Rest API Template
• Login and signup in SiteController
• Example of versioning and Blog Scenario
• Authentication Type from params
• Rate Limit from params
• Change auth_key for every login
• Auth_key have expiration
• each auth_key have application token
