Antidot Session Middleware

PSR-15 middleware that allows having session inside the request attributes.

Install

Install using composer, by default it uses an implementation of Aura Session.

composer require antidot-fw/session

Config

Using Antidot Framework Starter, it will work after adding the middleware to the pipeline. Also, you can use it in any PSR-15 compatible middleware pipeline using PSR-11 container.

<?php

$sessionFactory = new AuraSessionFactory();
$sessionMiddleware = new SessionMiddleware($sessionFactory($container));

Add it to your pipeline

<?php

use Antidot\Application\Http\Application;
use Antidot\Application\Http\Middleware\RouteDispatcherMiddleware;
use Antidot\Session\Application\Http\Middleware\SessionMiddleware;
...

return static function (Application $app) : void {
    $app->pipe(...);
    $app->pipe(SessionMiddleware::class); // added here
    $app->pipe(RouteDispatcherMiddleware::class);
    ...
};

Usage

The session will be stored as request attribute, For example using a Request handler, and it will be available in middleware loaded after it too.

<?php
// src/Handler/SomeHandler.php

declare(strict_types=1);

namespace App\Handler;

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;
use Psr\Http\Server\RequestHandlerInterface;
use Zend\Diactoros\Response\HtmlResponse;

class SomeHandler implements RequestHandlerInterface
{

    public function handle(ServerRequestInterface $request): ResponseInterface
    {
        /** @var \Antidot\Session\Application\Http\SessionSegment $session */
        $session = $request->getAttribute('session');

        $session->set('foo', 'bar');
        $session->set('baz', 'dib');
        $message = $session->get('foo'); // 'bar'
        $message = $session->get('baz'); // 'dib'
        $session->setFlash('message', 'Hello world!');
        $message = $session->getFlash('message'); // 'Hello world!'
        ...
    }
}

Adding custom session implementation

To create a wrapper for your own custom session, you need to implement both Antidot\Session\Application\Http\SessionSegment and Antidot\Session\Application\Http\SessionSegmentFactory clases, take a look to the Antidot\Session\Infrastructure\AuraSessionSegment and Antidot\Session\Infrastructure\AuraSessionSegmentFactory.

<?php

declare(strict_types=1);

namespace Antidot\Session\Application\Http;

interface SessionSegment
{
    public function get(string $identity);
    public function getFlash(string $identity);
    public function set(string $identity, $value): void;
    public function setFlash(string $identity, $value): void;
}

<?php

declare(strict_types=1);

namespace Antidot\Session\Application\Http;

use Psr\Http\Message\ServerRequestInterface;

interface SessionSegmentFactory
{
    public function __invoke(ServerRequestInterface $request): SessionSegment;
}
