Common utilities used by the middlewares' packages:

Used to create psr-7 instances of ServerRequestInterface, ResponseInterface, StreamInterface and UriInterface. Detects automatically Diactoros, Guzzle and Slim but you can register a different factory using the http-interop/http-factory interface.

use Middlewares\Utils\Factory;

$request = Factory::createServerRequest();
$response = Factory::createResponse();
$stream = Factory::createStream();
$uri = Factory::createUri('http://example.com');

//Register other factory
Factory::setResponseFactory(new FooResponseFactory());

$fooResponse = Factory::createResponse();

Minimalist PSR-15 compatible dispatcher. Used for testing purposes.

use Middlewares\Utils\Factory;
use Middlewares\Utils\Dispatcher;

$dispatcher = new Dispatcher([
    new Middleware1(),
    new Middleware2(),
    new Middleware3(),
    function ($request, $next) {
        $response = $next->handle($request);
        return $response->withHeader('X-Foo', 'Bar');
    }
]);

$response = $dispatcher->dispatch(Factory::createServerRequest());

To resolve and execute a callable. It can be used as a middleware, server request handler or a callable:

use Middlewares\Utils\CallableHandler;

$callable = new CallableHandler(function () {
    return 'Hello world';
});

$response = $callable();

echo $response->getBody(); //Hello world

The constructor accepts the following arguments:

• mixed $callable It can be callable or a string that can be resolved as callable, for example MyClass::method.
• array $arguments Extra arguments passed when it's invoked.
• CallableResolverInterface $resolver Used to resolve the $callable argument to generate something really callable. Currently there are two available resolvers: ReflectionResolver (used by default) and ContainerResolver (to use a PSR-11 container)

A collection of helpers for psr-7 message manipulation. It contains the following methods:

Helpers::fixContentLength(MessageInterface $response): MessageInterface

Fixes the Content-Length header based in the body size.
