requestEntityPresent

Signature

def requestEntityPresent: Directive0 

Description

A simple filter that checks if the request entity is present and only then passes processing to the inner route. Otherwise, the request is rejected with RequestEntityExpectedRejectionRequestEntityExpectedRejection.

See also requestEntityEmpty for the opposite effect.

Example

Scala
sourceval route =
  concat(
    requestEntityEmpty {
      complete("request entity empty")
    },
    requestEntityPresent {
      complete("request entity present")
    })

// tests:
Post("/", "text") ~> Route.seal(route) ~> check {
  responseAs[String] shouldEqual "request entity present"
}
Post("/") ~> route ~> check {
  responseAs[String] shouldEqual "request entity empty"
}
