Making a REST Service call in Scala using Dispatch

main.scala

  def main(args: Array[String]) {

    //Step 1 : Prepare the request object

    //even though its a https . doing a .secure is not required
    val request = url("https://maps.googleapis.com/maps/api/place/nearbysearch/json")
    val requestAsGet = request.GET //not required but lets be explicit

    //Step 2 : Set the required parameters
    val builtRequest = requestAsGet.addQueryParameter("key", "Almost gave away my key")
      .addQueryParameter("location", "40.5556204,-74.4162536")
      .addQueryParameter("radius", "10000")
      .addQueryParameter("sensor", "false")
      .addQueryParameter("keyword", "starbucks")

    //Step 3: Make the request (method is already set above)
    val content = Http(builtRequest)

    //Step 4: Once the response is available
    //response completed successfully
    content onSuccess {

      //Step 5 : Request was successful & response was OK
      case x if x.getStatusCode() == 200 =>
        //Step 6 : Response was OK, read the contents
        handleJsonOutput(x.getResponseBody)
      case y => //Step 7 : Response is not OK, read the error
        println("Failed with status code" + y.getStatusCode())
    }

    //Step 7 : Request did not complete successfully, read the error
    content onFailure {
      case x =>
        println("Failed but"); println(x.getMessage)
    }

    println("ENTER TO EXIT")
    readLine()
  }
