Get the JSON from HttpEntity

Question

I am using akka.http.scaladsl.model.HttpResponse, HttpEntity.

After getting the response , it is of type responseEntity of the format (Content-type: 'application/json', {MyJSONHERE}). Is there a way I can extract my json from the entity.

I tried entity.getDataBytes which gives the content of the entity in ByteString format. I want to properly read the JSON and parse it. Can someone guide me on this?

Answer 1

Code below works for me

entity.dataBytes.runWith(Sink.fold(ByteString.empty)(_ ++ _)).map(_.utf8String) map { result =>
  JsonMethods.parse(result)
}

dataBytes returns Source[ByteString, Any], Sink.fold combines all parts of the stream into one ByteString and utf8String converts ByteString into usual String.

Here is some useful docs about HttpEntity.

Answer 2

Can you try below code?

entity.getDataBytes.utf8String

That would return String representation of JSON.
