dev branch: resolve route with @domain missing.

[unicg]

Hi!

In dev branch on file www/index.php the resolve route with @Domain is missing.

spid-cie-oidc-php/www/index.php

Lines 507 to 532 in 9561b44

	// GET /resolve
	$f3->route(
	[
	'GET /resolve'
	],
	function ($f3) {
	$domain = $f3->get("PARAMS.domain") ? $f3->get("PARAMS.domain") : 'default';
	$config = $f3->get("CONFIG")['rp_proxy_clients'][$domain];
	$sub = $f3->get("GET.sub");
	$anchor = $f3->get("GET.anchor");
	if (empty($sub) || empty($anchor)) {
	$f3->error(400, "anchor or sub not not found");
	}
	$rp_database = $f3->get("RP_DATABASE");
	$logger = $f3->get("LOGGER");
	$mediaType = 'application/entity-statement+jwt';
	header('Content-Type: ' . $mediaType);
	$response = ResolveEndpoint::resolve($config, $rp_database, $sub, $anchor);
	echo $response;
	$logger->log('spid-cie-oidc-php', 'GET /resolve', $_GET, $response);
	}
	);

Maybe this should be changed like this:

// GET /resolve
// GET /@domain/resolve
$f3->route(
    [
    'GET /resolve',
    'GET /@domain/resolve'
    ],
    function ($f3) {
        $domain = $f3->get("PARAMS.domain") ? $f3->get("PARAMS.domain") : 'default';
        $config = $f3->get("CONFIG")['rp_proxy_clients'][$domain];
        // ...
    }
);

Do ResolveEndpoint.php need more code?

spid-cie-oidc-php/lib/Federation/ResolveEndpoint.php
