Signature

def extractDataBytes: Directive1[Source[ByteString, Any]]

Description

Extracts the entities data bytes as Source[ByteString, Any] from the RequestContext.

The directive returns a stream containing the request data bytes.

Example

val route =
  extractDataBytes { data ⇒
    val sum = data.runFold(0) { (acc, i) ⇒ acc + i.utf8String.toInt }
    onSuccess(sum) { s ⇒
      complete(HttpResponse(entity = HttpEntity(s.toString)))
    }
  }

// tests:
val dataBytes = Source.fromIterator(() ⇒ Iterator.range(1, 10).map(x ⇒ ByteString(x.toString)))
Post("/abc", HttpEntity(ContentTypes.`text/plain(UTF-8)`, data = dataBytes)) ~> route ~> check {
  responseAs[String] shouldEqual "45"
}
