Lumen-Passport as an oauth client grant Resource Server

Making Laravel Passport work with Lumen as a Client Grant Resource Server. This makes it easy to protect routes and check scopes via Passport middleware. This package requires https://github.com/dusterio/lumen-passport created by Denis Mysenko.

A simple service provider that makes Laravel Passport work with Lumen as a resource server

Dependencies

• PHP >= 7.1.3
• Lumen >= 5.3

Installation via Composer

First install Lumen if you don't have it yet:

$ composer create-project --prefer-dist laravel/lumen lumen-app

Then install Lumen Passport (it will fetch Laravel Passport along):

$ cd lumen-app
$ composer require gashey/lumen-passport-resource

Modify the bootstrap flow (bootstrap/app.php file)

We need to enable both Laravel Passport provider and Lumen-specific providers:

// Enable Facades
$app->withFacades();

// Enable Eloquent
$app->withEloquent();

// Enable the client middleware and scopes middleware (shipped with Passport)
$app->routeMiddleware([
    'client' => \Laravel\Passport\Http\Middleware\CheckClientCredentials::class,
    'scopes' => \Laravel\Passport\Http\Middleware\CheckScopes::class,
]);

// Finally register three service providers - original one and Lumen adapter
$app->register(Laravel\Passport\PassportServiceProvider::class);
$app->register(Dusterio\LumenPassport\PassportServiceProvider::class);
$app->register(Gashey\LumenPassportResource\PassportServiceProvider::class);

Run Migrations for Gashey Passport

# Create new tables for Gashey Passport 
php artisan migrate

Resource Server Public Key

This package requires your public key from your Passport Authorization Server.

Copy the "oauth-public.key" file from the 'storage folder' of your Authorization Server project into the 'storage folder of your Resource Server project.

Configuration

Edit config/auth.php to suit your needs. A simple example:

return [
    'defaults' => [
        'guard' => 'api',
        'passwords' => 'users',
    ],

    'guards' => [
        'api' => [
            'driver' => 'passport',
            'provider' => 'users',
        ],
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => \App\User::class
        ]
    ]
];

Load the config in bootstrap/app.php since Lumen doesn't load config files automatically:

$app->configure('auth');

User model

Make sure your user model uses Passport's HasApiTokens trait, eg.:

class User extends Model implements AuthenticatableContract, AuthorizableContract
{
    use HasApiTokens, Authenticatable, Authorizable;

    /* rest of the model */
}

Protect routes

Add the client and scopes middleware to your routes

$router->group(['middleware' => ['client', 'scopes:...'], 'prefix' => 'api/v1'], function () use ($router) {
    
});

Running with Apache httpd

If you are using Apache web server, it may strip Authorization headers and thus break Passport.

Add the following either to your config directly or to .htaccess:

RewriteEngine On
RewriteCond %{HTTP:Authorization} ^(.*)
RewriteRule .* - [e=HTTP_AUTHORIZATION:%1]
