README

The RequestHandler class is designed to handle HTTP requests by processing a stack of middlewares. It implements the RequestHandlerInterface to ensure compatibility with standardized request handling protocols.

Installation

You can install the RequestHandler class using Composer. Run the following command:

composer require effectra/http-server-handler

Usage

To use the RequestHandler, follow these steps:

1. Create an instance of the RequestHandler class, providing a ResponseInterface object and an optional array of middlewares as parameters in the constructor.

use Effectra\Http\Server\RequestHandler;
use Effectra\Http\Message\Response;

// Create a response object
$response = new Response();

// Create an array of middlewares
$middlewares = [
    new YourMiddleware(),
    // Add more middlewares as needed
];

// Create an instance of RequestHandler
$requestHandler = new RequestHandler($response, $middlewares);

1. Call the handle method of the RequestHandler class, passing a ServerRequestInterface object representing the incoming request.

use Psr\Http\Message\ServerRequestInterface;

// Create a ServerRequestInterface object representing the incoming request
$request = ServerRequestInterface::fromGlobals();

// Handle the request
$response = $requestHandler->handle($request);

1. The handle method will process the middlewares stack, executing each middleware in the order they were added. It will return a ResponseInterface object representing the response generated by the middlewares.

use Psr\Http\Message\ResponseInterface;

// Get the response generated by the middlewares stack
echo $response->getBody();

Additional Methods

getLastRequest

The RequestHandler class provides a convenient method, getLastRequest, to retrieve the last processed request. It returns a ServerRequestInterface|null object representing the last request or null if no request has been processed.

use Psr\Http\Message\ServerRequestInterface;

// Retrieve the last processed request
$lastRequest = $requestHandler->getLastRequest();

if ($lastRequest instanceof ServerRequestInterface) {
    // Process the last request
} else {
    // No request has been processed yet
}
