Making Laravel Passport work with Lumen

A simple service provider that makes Laravel Passport work with Lumen

Dependencies

• PHP >= 5.6.3
• 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 dusterio/lumen-passport

Or if you prefer, edit composer.json manually:

{
    "require": {
        "dusterio/lumen-passport": "^0.3.0"
    }
}

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

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

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

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

// Enable auth middleware (shipped with Lumen)
$app->routeMiddleware([
    'auth' => App\Http\Middleware\Authenticate::class,
]);

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

Using with Laravel Passport 7.3.2 and newer

Laravel Passport 7.3.2 had a breaking change - new method introduced on Application class that exists in Laravel but not in Lumen. You could either lock in to an older version or swap the Application class like follows at the top of your bootstrap/app.php file:

$app = new \Dusterio\LumenPassport\Lumen7Application(
    dirname(__DIR__)
);

If you look inside this class - all it does is adding an extra method configurationIsCached() that always returns false.

Migrate and install Laravel Passport

# Create new tables for Passport
php artisan migrate

# Install encryption keys and other necessary stuff for Passport
php artisan passport:install

Installed routes

This package mounts the following routes after you call routes() method (see instructions below):

Please note that some of the Laravel Passport's routes had to 'go away' because they are web-related and rely on sessions (eg. authorise pages). Lumen is an API framework so only API-related routes are present.

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');

Registering Routes

Next, you should call the LumenPassport::routes method within the boot method of your application (one of your service providers). This method will register the routes necessary to issue access tokens and revoke access tokens, clients, and personal access tokens:

\Dusterio\LumenPassport\LumenPassport::routes($this->app);

You can add that into an existing group, or add use this route registrar independently like so;

\Dusterio\LumenPassport\LumenPassport::routes($this->app, ['prefix' => 'v1/oauth']);

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 */
}

Extra features

There are a couple of extra features that aren't present in Laravel Passport

Allowing multiple tokens per client

Sometimes it's handy to allow multiple access tokens per password grant client. Eg. user logs in from several browsers simultaneously. Currently Laravel Passport does not allow that.

use Dusterio\LumenPassport\LumenPassport;

// Somewhere in your application service provider or bootstrap process
LumenPassport::allowMultipleTokens();

Different TTLs for different password clients

Laravel Passport allows to set one global TTL for access tokens, but it may be useful sometimes to set different TTLs for different clients (eg. mobile users get more time than desktop users).

Simply do the following in your service provider:

// Second parameter is the client Id
LumenPassport::tokensExpireIn(Carbon::now()->addYears(50), 2); 

If you don't specify client Id, it will simply fall back to Laravel Passport implementation.

Console command for purging expired tokens

Simply run php artisan passport:purge to remove expired refresh tokens and their corresponding access tokens from the database.

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]

I've just started a educational YouTube channel that will cover top IT trends in software development and DevOps: config.sys

Also I'm happy to announce my newest tool – GrammarCI, an automated (as a part of CI/CD process) spelling and grammar checks for your code so that your users don't see your typos :)
