README

This middleware implements a CAS client for use with frameworks such as Slim. It is designed to authenticate users but leaves the session implementation up to the developer for maximum flexibility.

Install

$ composer require cilefen/cas-middleware

Usage

Implement Cilefen\Middleware\SessionManagerInterface. In your implementation, start a session your desired way:

namespace App;

use Cilefen\Middleware\SessionManagerInterface;

class SessionManager implements SessionManagerInterface
{
    private $url;

    public function __construct(string $url)
    {
        $this->url = $url;
    }

    public function startSession(string $user)
    {
        $_SESSION['user'] = $user;
    }

    public function isAuthenticated(): bool
    {
        return !empty($_SESSION['user']);
    }

    public function serverUrl(): string
    {
        return $this->url;
    }
}

Add the middleware to routes or route groups needing authentication. CasMiddleware requires the SessionManager you created above. In addition, the middleware requires a Guzzle client.

$app = new \Slim\App();

$app->get('/login', function (Request $request, Response $response, array $args) {
    return $response
        ->withStatus(302)
        ->withHeader('Location', '/');
})->add(new \Cilefen\Middleware\CasMiddleware(new \App\SessionManager('https://localhost:8443/cas'), new \GuzzleHttp\Client()));
