==================================

[](#chadicusslimoauth2middleware)

> **Fork Notice:** This is a maintained fork of the abandoned [`chadicus/slim-oauth2-middleware`](https://github.com/chadicus/slim-oauth2-middleware) package. Updated for PHP 8.1+ and PSR-15.

[![License](https://camo.githubusercontent.com/734508b359fe427e61876360db5d0c09f026c3a81629ce7688d94f2a31989e01/68747470733a2f2f706f7365722e707567782e6f72672f6d616b73696d6f7669632f736c696d2d6f61757468322d6d6964646c65776172652f6c6963656e7365)](https://packagist.org/packages/maksimovic/slim-oauth2-middleware)

PSR-15 middleware for using [OAuth2 Server](http://bshaffer.github.io/oauth2-server-php-docs/) within any PSR-15 compatible framework, including [Slim 4](http://www.slimframework.com/).

Requirements
------------

[](#requirements)

PHP 8.1 or later.

Installation
------------

[](#installation)

```
composer require maksimovic/slim-oauth2-middleware
```

Example usage
-------------

[](#example-usage)

```
use Chadicus\Slim\OAuth2\Middleware\Authorization;
use OAuth2;
use OAuth2\Storage;
use OAuth2\GrantType;

$storage = new Storage\Memory([
    'client_credentials' => [
        'administrator' => ['client_id' => 'administrator', 'client_secret' => 'password', 'scope' => 'superUser'],
    ],
]);

$server = new OAuth2\Server(
    $storage,
    ['access_lifetime' => 3600],
    [new GrantType\ClientCredentials($storage)]
);

$auth = new Authorization($server, $container);

// Slim 4
$app->get('/foos', $handler)->add($auth);
$app->post('/foos', $handler)->add($auth->withRequiredScope(['superUser']));
```

`$container` must be either an `ArrayAccess` or expose a `set($key, $value)` method (e.g. PHP-DI). The decoded access token is stored under the `'token'` key on success and added to the request as the `oauth2-token` attribute.

Development
-----------

[](#development)

```
composer install
composer test
composer test:coverage
composer cs-check
```
