I solved this.
I found the $router->match() method, which I am using against a
cleaned up version of the $request->server->get('HTTP_REFERER'). This
gives me the route parameters I need to generate my redirect route.
Here is the completed action:
public function switchLangAction($_locale)
{
$newLang = ($_locale == "en") ? "fr" : "en";
$request = $this->get('request');
$router = $this->get('router');
$domain = $request->server->get('HTTP_HOST');
$referrer = $request->server->get('HTTP_REFERER');
// remove the protocol
$referrer = preg_replace(';\b((ftp|https?)://)+?\b;', '',
$referrer);
// remove the domain
$referrer = str_replace($domain, '', $referrer );
// remove the controller
$referrer = str_replace($request->getBaseUrl(), '',
$referrer);
// remove the query string
$referrer = preg_replace('/\?.*/', '', $referrer);
// match the resulting cleaned up route
$referrerParams = $router->match( $referrer );
// pluck the _route out of the params
$referrerRoute = $referrerParams['_route'];
unset($referrerParams['_route']);
// switch the locale
$referrerParams['_locale'] = $newLang;
$response = new RedirectResponse( $this->generateUrl(
$referrerRoute,
$referrerParams
));
return $response;
}
