title: Using Fuel in Kotlin with GET works but POST doesn't
body: <p>I am using Fuel to do a server call in Kotlin but, while the GET version works, the POST doesn't seem to pass anything to the server.  </p>
  
  <p>I based my code on a nice <a href="http://www.androidmads.info/2018/01/kotlin-http-example-using-fuel-http.html" rel="nofollow noreferrer">Fuel Kotlin tutorial by Mushtaq</a>:</p>
  
  <pre><code>    val parameters = listOf("something" to "100")
      fun httpPostJson(view: View) {
      try {
          Fuel.post(PATH, parameters).responseJson { request, response, result -&gt;
              tvPostResponse!!.text = result.get().content
          }
      } catch (e: Exception) {
          tvPostResponse!!.text = e.message
      } finally {
          progress!!.dismiss()
      }
  }
  </code></pre>
  
  <p>The server script is just a PHP file that does a var_dump() for $_REQUEST, $_GET, and $_POST.  It shows the expected values for Fuel.get() but they are all array(0) for the Fuel.post() call.  I've tried calling it from a regular webpage and it works as expected for both GET and POST so it seems like I'm missing something in the Kotlin code.  I have no idea what...maybe some simple setting?  Any thoughts would be greatly appreciated!</p>
