head
head
Signature
Description
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.
注釈
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
val route = head { complete("This is a HEAD request.") }
// tests:
Head("/") ~> route ~> check {
responseAs[String] shouldEqual "This is a HEAD request."
}
