POST request with JSON in Dispatch and Scala

I'm having trouble sending a POST request using a JSON object using Dispatch and Scala.

The POST request works fine, as I tested it with curl:

~/workspace $ curl -vd 'tracker={"project":"campaign","event":"home","number":"100"}'  http://exampleurl:8145/test

and I get an HTTP 200 response as expected

But when I try to do the same with the Dispatch library ( http://dispatch.databinder.net/Dispatch.html ):

scala> Http(url("http://exampleurl:8145/test") << "tracker={'project':'campaign','event':'home','number':'100'}" >|)

here is what i get:

dispatch.StatusCode: Unexpected response code: 404

I am not sure why it lacks the tracker parameter that I am trying to pass.

Anyone's thoughts?

I think you want to publish it as a pair of name values:

Http(url("http://exampleurl:8145/test") << 
  Map("tracker" -> "{'project':'campaign','event':'home','number':'100'}") >|)
