Code

protected static function getNormalizedRequestMethod(RouteMatchInterface $route_match) {

  // Symfony is built to transparently map HEAD requests to a GET request. In
  // the case of the REST module's RequestHandler though, we essentially have
  // our own light-weight routing system on top of the Drupal/symfony routing
  // system. So, we have to respect the decision that the routing system made:
  // we look not at the request method, but at the route's method. All REST
  // routes are guaranteed to have _method set.
  // Response::prepare() will transform it to a HEAD response at the very last
  // moment.
  // @see https://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html#sec9.4
  // @see \Symfony\Component\Routing\Matcher\UrlMatcher::matchCollection()
  // @see \Symfony\Component\HttpFoundation\Response::prepare()
