PSR-7和PSR-15兼容的中间件实现，用于在基于PSR-7的应用程序中启用会话。

安装

使用composer安装。

$ composer require sulaco-tech/psr7-sessions

要求

此分支需要PHP 7.0或更高版本以及内置扩展

• JSON
• PCRE

以下包也需要

• sulaco-tech/base58

用法

您可以在任何PSR-15兼容的中间件中使用SulacoTech\PSR7Sessions\SessionMiddleware。

在一个slim/slim应用程序中，这会看起来像以下这样

use \Slim\Factory\AppFactory;
use \Psr\Http\Message\ResponseInterface as Response;
use \Psr\Http\Message\ServerRequestInterface as Request;
use \SulacoTech\PSR7Sessions\SessionMiddleware;
use \SulacoTech\PSR7Sessions\SessionFileStorage;
use \SulacoTech\PSR7Sessions\SessionFileStorageConfiguration;

// create application
$app = AppFactory::create();

// prepare configuration
$sessionsDirectory = __DIR__ . '/../tmp/sessions';
$sessionName = 'example';
$sessionsExpirationTime = 300; // in seconds
$config = new SessionFileStorageConfiguration($sessionsDirectory, $sessionName, $sessionsExpirationTime);

// create storage with some configuration
$sessionStorage = new SessionFileStorage($config);

// call garbage collector
$sessionStorage->gc();

// create and add middleware
$app->add(new SessionMiddleware($sessionStorage));

// basic example
$app->get('/hello/{name}', function (Request $request, Response $response, array $args) {

	// get session
	$session = $request->getAttribute(SessionMiddleware::SESSION_ATTRIBUTE);

	// read and update session's data
	$counter = $session->get('counter', 0);
	$session->set('counter', ++ $counter);

	// same instructions using array access style
	//$counter = $session['counter'] ?? 0;
	//$session['counter'] = ++ $counter;

	// make a response
	$response->getBody()->write("Hello, {$args['name']}! This page is visited $counter times.");

	return $response;
});

// run application
$app->run();
