Is there a way to get scala code to ignore ssl validation?

Question

I am trying to download my facebook profile image. I successully use oauth to connect and get all the right tokens, and am told by the facebook API the url for my profile image.

However when I try and retrieve it, I get an error about invalid tls. I have included some scala code showing how I download the image. I can get it if I change to http. but https fails. Can anyone suggest why? Do I need to ignore ssl validation?

I am using net.databinder.dispatch %% dispatch-core % 0.11.2 in my build.sbt

scala> import dispatch.Defaults._
scala> import dispatch._
scala> import scala.concurrent.Await
scala> import scala.concurrent.duration._

scala>   def fetchUrl( uri : String ) : Array[Byte] = {
     |     val svc = url(uri)
     |     val future_img = Http(svc OK as.Bytes)
     |     Await.result(future_img, Duration(10, "seconds"))
     |
     |     future_img()
     |   }
fetchUrl: (uri: String)Array[Byte]

throws an exceeption about an invalid ss/tls record

If I change the https to http then it works. Also if I paste the URI in to the browser address bar it works as https and reports the cert is valid.

Answer 1

My build.sbt was also bringing in 0.8.10 of dispatch-core. I am still having issues but will post another question. Removing the dependency on 0.8.10 resolved the ssl issue.
