Proxy Scheme, Host and Port detection middleware

PSR-15 Middleware that determines the scheme, host and port from the 'X-Forwarded-Proto', 'X-Forwarded-Host' and 'X-Forwarded-Port' headers and updates the Request's Uri object.

You can set a list of proxies that are trusted as the second constructor parameter. If this list is set, then the proxy headers will only be checked if the REMOTE_ADDR is in the trusted list.

Installation

composer require akrabat/proxy-detection-middleware

Usage

In Slim 3:

$trustedProxies = ['10.0.0.1', '10.0.0.2'];
$app->add(new RKA\Middleware\ProxyDetection($trustedProxies));

$app->get('/', function ($request, $response, $args) {
    $scheme = $request->getUri()->getScheme();
    $host = $request->getUri()->getHost();
    $port = $request->getUri()->getPort();

    return $response;
});
