Play-mini: how to return an image

I'm trying to serve an image from a play-mini application.

object App extends Application {
  def route = {
    case GET(Path("/image")) => Action { request =>
      Ok( Source.fromInputStream(getClass.getResourceAsStream("image.gif")).toArray ).as("image/gif")
    }
  }
}

Unfortunately, this does noe work :) I get the following error

 Cannot write an instance of Array[Char] to HTTP response. Try to define a Writeable[Array[Char]]
Solution

  • Don't know about play-mini, but in play20 there is predefined Writeable[Array[Byte]], so you need to provide Array[Byte] for file handling. Also, there is a bit of documentation about serving files in play20.
