The OpenIDConnect Laravel package is meant to provide you an opportunity to easily authenticate users using OpenID Connect protocol.

Installation

To install this package you will need:

• Laravel 5.4+
• PHP 7.1+

Use composer to install

composer require furdarius/oidconnect-laravel:dev-master

Open config/app.php and register the required service providers above your application providers.

'providers' => [
    ...
    Laravel\Socialite\SocialiteServiceProvider::class,
    Furdarius\OIDConnect\ServiceProvider::class
    ...
]

If you'd like to make configuration changes in the configuration file you can pubish it with the following Aritsan command:

php artisan vendor:publish --provider="Furdarius\OIDConnect\ServiceProvider"

After that, roll up migrations:

php artisan migrate

Usage

Configuration

At first you will need to add credentials for the OpenID Connect service your application utilizes. These credentials should be placed in your config/opidconnect.php configuration file.

<?php

return [
    'client_id' => 'CLIENT_ID_HERE',
    'client_secret' => 'CLIENT_SECRET_HERE',
    'redirect' => env('APP_URL') . '/auth/callback',
    'auth' => 'https://oidc.service.com/auth',
    'token' => 'https://oidc.service.com/token',
    'keys' => 'https://oidc.service.com/keys',
];

Endpoints

Now, your app has auth endpoints:

• GET /auth/redirect - Used to redirect client to Auth Service login page.
• GET /auth/callback - Used when Auth Service redirect client to callback url with code.
• POST /auth/refresh - Used by client for ID Token refreshing.

Middleware

You need to use Auth Middleware on protected routes. Open App\Http\Kernel and register middleware in $routeMiddleware:

protected $routeMiddleware = [
    'token' => \Furdarius\OIDConnect\TokenMiddleware::class
];

And then use it as usual:

Route::middleware('token')->get('/protected', function (Illuminate\Http\Request $request) {
    return "You are on protected zone";
});

User Auth

Create your own StatelessGuard and setup it in config/auth.php. Example:

Guard:

<?php

namespace App\Auth;

use Illuminate\Auth\AuthenticationException;
use Illuminate\Auth\GuardHelpers;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Contracts\Auth\Guard;
use Illuminate\Support\Traits\Macroable;

class StatelessGuard implements Guard
{
    use GuardHelpers, Macroable;

    /**
     * @return \Illuminate\Contracts\Auth\Authenticatable
     * @throws AuthenticationException
     */
    public function user()
    {
        if (null === $this->user) {
            throw new AuthenticationException('Unauthenticated user');
        }

        return $this->user;
    }

    /**
     * @param array $credentials
     * @return bool
     */
    public function validate(array $credentials = [])
    {
        return $this->user instanceof Authenticatable;
    }
}

Config (config/auth.php):

'defaults' => [
    'guard' => 'stateless',
    'passwords' => 'users',
],

...

'guards' => [
    'stateless' => [
        'driver' => 'stateless'
    ]
],

Then implement own Authenticator. Example:

<?php

namespace App\Auth;

use App\User;
use Furdarius\OIDConnect\Contract\Authenticator;
use Furdarius\OIDConnect\Exception\AuthenticationException;
use Lcobucci\JWT\Token\DataSet;

class PersonAuthenticatorAdapter implements Authenticator
{
    /**
     * @param DataSet $claims
     *
     * @return void
     */
    public function authUser(DataSet $claims)
    {
        $email = $claims->get('email');
        if (!$email) {
            throw new AuthenticationException('User\'s email not present in token');
        }

        $model = new User(['email' => $email]);

        \Auth::setUser($model);
    }
}

And implement auth guard service provider. Example:

<?php

namespace App\Auth;

use Furdarius\OIDConnect\Contract\Authenticator;
use Illuminate\Support\ServiceProvider;

class AuthenticatorServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        \Auth::extend('stateless', function () {
            return new StatelessGuard();
        });
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton(Authenticator::class, function ($app) {
            return new PersonAuthenticatorAdapter();
        });
    }
}

Then register it in config/app.php:

'providers' => [
    ...
    App\Auth\AuthenticatorServiceProvider::class,
    ...
]

Now you can use \Auth::user(); for getting current user information.
