akka HttpResponse read body as String scala

Question

So I have a function with this signature (akka.http.model.HttpResponse):

def apply(query: Seq[(String, String)], accept: String): HttpResponse

Answer 1

Here is simple directive that extracts string from request's body

def withString(): Directive1[String] = {
  extractStrictEntity(3.seconds).flatMap { entity =>
    provide(entity.data.utf8String)
  }
}
