head
Matches requests with HTTP method HEAD.
This directive filters the incoming request by its HTTP method. Only requests with method HEAD are passed on to the inner route. All others are rejected with a MethodRejection, which is translated into a 405 Method Not Allowed response by the default RejectionHandler.
Note
By default, akka-http handles HEAD-requests transparently by dispatching a GET-request to the handler and stripping of the result body. See the akka.http.server.transparent-head-requests setting for how to disable this behavior.
Example
final Route route = head(complete("This is a HEAD request."));
testRoute(route).run(HttpRequest.HEAD("/")).assertEntity(
"This is a HEAD request.");
