FOSOAuthServerBundle with FOSUserBundle - How to make it works?

Question

Currently my project works very well. I use FOSUserBundle for the management of my users. Now, I want to implement OAuth, so I'm using FOSOAuthServerBundle. Most of developers recommend this bundle for implement OAuth.

I followed the documentation of FOSOAuthServerBundle. Normally, I have to add more information in my security.yml but I don't know exactly what I have to do ...

Here is my security.yml :

security:
    encoders:
       Symfony\Component\Security\Core\User\User: plaintext
       Moodress\Bundle\UserBundle\Entity\User: sha512

    role_hierarchy:
       ROLE_ADMIN:       ROLE_USER
       ROLE_SUPER_ADMIN: [ROLE_ADMIN, ROLE_ALLOWED_TO_SWITCH]

    providers:
       main:
           id: fos_user.user_provider.username

    firewalls:
        dev:
            pattern:  ^/(_(profiler|wdt)|css|images|js)/
            security: false
        oauth_token:
            pattern:    ^/oauth/v2/token
            security:   false

        oauth_authorize:
            pattern:    ^/oauth/v2/auth

        main:
            pattern: ^/
            fos_oauth:  true
            stateless:  true
            anonymous: true

I guess that there are some information to add in firewalls maybe ??

I really don't know how to make works FOSOAuthServerBundle with FOSUserBundle. Before, with just FOSUserBundle, I used the login form and the login check of FOSUserBundle. Now that I put all the basic configuration of FOSOAuthServerBundle, what I have to do next ? Which form should I use? Which login check? The token is created automatically by FOSOAuthServerBundle ? In the documentation, they show how to create a client... Am I supposed to add this code in my project ? If yes... where ? :/

I found this article on the web : http://blog.logicexception.com/2012/04/securing-syfmony2-rest-service-wiith.html

I tried to implement this, but I can't believe that we need to add all this files to make it work...

If someone knows how to make works FOSOAuthServerBundle with FOSUserBundle, it would be very helpful.

I've just installed this bundle and started playing with it.

I think you need to learn first more about how OAuth authentication works.

This way you will understand that the FOSUserBundle mechanisms are not exactly the same as OAuth.

Your link is the best piece of information to setup correctly the bundle.

I'm using MongoDB to store all the 4 required documents : Client, AuthCode, RefreshToken and AccessToken

The step called "Create a new client" is basically the "register" process of FOSUserBundle for OAuth.

OAuth will use the client to give permission to access.

The main idea of OAuth is to secure an API, therefore I suggest you switch your config to anonymous: false

Then you'll see the message :

{"error":"access_denied","error_description":"OAuth2 authentication required"}

when you call your API

The idea of OAuth is to get an Access Token to call your API. Read this : http://blog.tankist.de/blog/2013/07/16/oauth2-explained-part-1-principles-and-terminology/

This is when the OAuth authentication process needs to be followed.

There are 5 basic methods to use :

const GRANT_TYPE_AUTH_CODE = 'authorization_code';
const GRANT_TYPE_IMPLICIT = 'token';
const GRANT_TYPE_USER_CREDENTIALS = 'password';
const GRANT_TYPE_CLIENT_CREDENTIALS = 'client_credentials';
const GRANT_TYPE_REFRESH_TOKEN = 'refresh_token';

To learn about each, go find more documentation about OAuth RFC.

Each of them correspond to a specific call to : /oauth/v2/token?client_id=[CLIENT_ID]&response_type=code&redirect_uri=URL&grant_type=token

Cf: https://github.com/FriendsOfSymfony/oauth2-php/blob/master/lib/OAuth2/OAuth2.php#L182

Also read this link : blog.tankist.de/blog/2013/08/20/oauth2-explained-part-4-implementing-custom-grant-type-symfony2-fosoauthserverbundle/

The part "Time to test" explains how to use OAuth.

I'm still working on it.

Hope it helps.

Also this link indicates how to use FOSUserBundle User & UserManager probably to use the password grant_type : If you're authenticating users, don't forget to set the user provider.

Here's an example using the FOSUserBundle user provider: https://github.com/FriendsOfSymfony/FOSOAuthServerBundle/blob/master/Resources/doc/index.md

# app/config/config.yml
fos_oauth_server:
    ...

    service:
        user_provider: fos_user.user_manager
