AlbOAuth2ServerBundle

Installation

Installation is a quick 6 step process:

1. Download AlbOAuth2ServerBundle
2. Configure the Autoloader
3. Enable the Bundle
4. Create your User class
5. Configure your application's security.yml
6. Configure the AlbOAuth2ServerBundle

Step 1: Download AlbOAuth2ServerBundle and oauth2-php

Ultimately, the AlbOAuth2ServerBundle files should be downloaded to the vendor/bundles/Alb/OAuth2ServerBundle directory and the oauth2-php files to the vendor/oauth2-php directory.

This can be done in several ways, depending on your preference. The first method is the standard Symfony2 method.

Using the vendors script

Add the following lines in your deps file:

[AlbOAuth2ServerBundle]
    git=git://github.com/arnaud-lb/AlbOAuth2ServerBundle.git
    target=bundles/Alb/OAuth2ServerBundle
[oauth2-php]
    git=git://github.com/arnaud-lb/oauth2-php.git

Now, run the vendors script to download the bundle:

$ php bin/vendors install

Using submodules

If you prefer instead to use git submodules, then run the following:

$ git submodule add git://github.com/arnaud-lb/AlbOAuth2ServerBundle.git vendor/bundles/Alb/OAuth2ServerBundle
$ git submodule add git://github.com/arnaud-lb/oauth2-php.git vendor/oauth2-php
$ git submodule update --init

Step 2: Configure the Autoloader

Add the Alb and OAuth2 namespaces to your autoloader:

<?php
// app/autoload.php

$loader->registerNamespaces(array(
    // ...
    'Alb'    => __DIR__.'/../vendor/bundles',
    'OAuth2' => __DIR__.'/../vendor/oauth2-php/lib',
));

Step 3: Enable the bundle

Finally, enable the bundle in the kernel:

<?php
// app/AppKernel.php

public function registerBundles()
{
    $bundles = array(
        // ...
        new Alb\OAuth2ServerBundle\AlbOAuth2ServerBundle(),
    );
}

Step 4: Create model classes

This bundle needs to persist some classes to a database:

• OAuth2Client (OAuth2 consumers)
• OAuth2AccessToken
• OAuth2AuthCode

Your first job, then, is to create these classes for your application. These classes can look and act however you want: add any properties or methods you find useful.

These classes have just a few requirements:

1. They must extend one of the base classes from the bundle
2. They must have an id field

In the following sections, you'll see examples of how your classes should look, depending on how you're storing your data.

Your classes can live inside any bundle in your application. For example, if you work at "Acme" company, then you might create a bundle called AcmeApiBundle and place your classes in it.

Warning:

If you override the __construct() method in your classs, be sure to call parent::__construct(), as the base class depends on this to initialize some fields.

a) Doctrine ORM classes

If you're persisting your data via the Doctrine ORM, then your classes should live in the Entity namespace of your bundle and look like this to start:

<?php
// src/Acme/ApiBundle/Entity/OAuth2Client.php

namespace Acme\ApiBundle\Entity;

use Alb\OAuth2Server\Entity\OAuth2Client as BaseOAuth2Client;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class OAuth2Client extends BaseOAuth2Client
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

<?php
// src/Acme/ApiBundle/Entity/OAuth2AccessToken.php

namespace Acme\ApiBundle\Entity;

use Alb\OAuth2Server\Entity\OAuth2AccessToken as BaseOAuth2AccessToken;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class OAuth2AccessToken extends BaseOAuth2AccessToken
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToOne(targetEntity="OAuth2Client")
     * @ORM\JoinColumn(nullable=false)
     */
    protected $client;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

<?php
// src/Acme/ApiBundle/Entity/OAuth2AuthCode.php

namespace Acme\ApiBundle\Entity;

use Alb\OAuth2Server\Entity\OAuth2AuthCode as BaseOAuth2AuthCode;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class OAuth2AuthCode extends BaseOAuth2AuthCode
{
    /**
     * @ORM\Id
     * @ORM\Column(type="integer")
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\ManyToOne(targetEntity="OAuth2Client")
     * @ORM\JoinColumn(nullable=false)
     */
    protected $client;

    public function __construct()
    {
        parent::__construct();
        // your own logic
    }
}

Step 5: Configure your application's security.yml

In order for Symfony's security component to use the AlbOAuth2ServerBundle, you must tell it to do so in the security.yml file. The security.yml file is where the basic configuration for the security for your application is contained.

Below is a minimal example of the configuration necessary to use the AlbOAuth2ServerBundle in your application:

# app/config/security.yml
security:
    firewalls:
        api:
            pattern:    ^/api
            alb_oauth2: true
            stateless:  true

    access_control:
        # You can omit this if /api can be accessed both authenticated and anonymously
        - { path: ^/api, roles: [IS_AUTHENTICATED_FULLY] }

The URLs under /api will use OAuth2 to authenticate users.

Step 6: Configure AlbOAuth2ServerBundle

Import the routing.yml configuration file in app/config/routing.yml:

# app/config/routing.yml
alb_oauth2:
    resource: "@AlbOAuth2ServerBundle/Resources/config/routing.yml"

Add AlbOAuth2ServerBundle settings in app/config/config.yml:

# app/config/config.yml
alb_o_auth2_server:
    db_driver:  orm
    oauth2_client_class:        Acme\ApiBundle\Entity\OAuth2Client
    oauth2_access_token_class:  Acme\ApiBundle\Entity\OAuth2AccessToken
    oauth2_auth_code_class:     Acme\ApiBundle\Entity\OAuth2AuthCode

Symfony 2.0.x only

Import the security.yml configuration file in app/config/config.yml:

# app/config/config.yml
imports:
    # Symfony 2.0.x only
    - { resource: "@AlbOAuth2ServerBundle/Resources/config/security.yml" }

Usage

The token endpoint is at /oauth/v2/token by default (see Resources/config/routing.yml).

An authorize endpoint can be implemented with the finishClientAuthorization method on the alb.oauth2.server.server_service service:

<?php

if ($form->isValid()) {
    try {
        $response = $service->finishClientAuthorization(true, $currentUser, $request, $scope);
        return $response;
    } catch(\OAuth2\OAuth2ServerException $e) {
        return $e->getHttpResponse();
    }
}

TODO

• More tests
• Add model classes for OAuth2RefreshToken
• Add methods for refresh_token authorization types in the default storage adapter
• Add a default controler for the /authorize endpoint
