Play Framework: How can I read a png image using the WS client?

image, java, playframework, playframework-2.0, png

Solution

In Play 2.0.4 you can't do that in Java. First there is no method for binaries in the API: http://www.playframework.org/documentation/api/2.0.4/java/play/libs/WS.Response.html . I tried the method WS.Response.getBody(), but the bytes weren't correct.

But the Scala API supports binary files in Play 2.0.4:

package controllers

import play.api._
import libs.ws.WS
import play.api.mvc._

object Application extends Controller {

  def getImage = Action {
    Async {
      WS.url("http://someimageserver/myimage.png").get().map { r =>
        Ok(r.getAHCResponse.getResponseBodyAsBytes).as("image/png")
      }
    }
  }

}

From Play 2.1 on there is support for binaries in Java: https://github.com/playframework/Play20/blob/master/framework/src/play-java/src/main/java/play/libs/WS.java#L565

Problem

Hi I'd like to read a PNG from a web service and then respond back to the client with the PNG. (think something like an image proxy). I am using Java and the Play Framework 2.0 with the WS class. Currently I have: ``` public static Result getimage(){ WSRequestHolder requestHolder = WS.url("http://someimageserver/myimage.png"); Promise<WS.Response> getImageResult = requestHolder.get(); //How do I create an play.mvc.Result from this so I can sent it back to the callee? } ``` Any help is much appreciated.
