Get values by POST in Restlet framework

Question

I'm tring to get the parameters sent by POST using the Restlet framework but I can't find the way.

Here's what I have working with GET:

   @Get
   public StringRepresentation represent() {
      String search = getQuery().getValues("search");
      String folder = getQuery().getValues("folder");

      LinkedHashMap<String, String> list = search(search, folder);
      return new StringRepresentation(JSONObject.toJSONString(list), MediaType.APPLICATION_JSON);
   }

What should I do to get the data from POST?

Update Still having troubles getting the 415 Unsupported Media Type after trying this:

   @Post("json")
   public StringRepresentation represent(Representation entity) {
       final Form form = new Form(entity);
       String name = form.getFirstValue("search");

      return new StringRepresentation(name, MediaType.APPLICATION_JSON);
   }

For more information, I'm making the POST request through PHP by using cURL.

Update 2 By removing the ("json") I don't get the error message anymore but the name variable is empty.

Update 3 This is the PHP code I'm using:

public function restful(){
    $result = $this->callAPI('POST', 'http://localhost:8182/xxxx', array('search'=> 'demo', 'folder' => 'xxxxxx'));
    print_r($result);
    die();
}


// Method: POST, PUT, GET etc
// Data: array("param" => "value") ==> index.php?param=value

public function callAPI($method, $url, $data = false){
    $curl = curl_init($url);

    switch ($method)
    {
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);

            if ($data){
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            }
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_PUT, 1);
            break;
        default:
            if ($data){
                $url = sprintf("%s?%s", $url, http_build_query($data));
            }
    }

    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
    curl_setopt($curl, CURLOPT_SSL_VERIFYHOST,  2);
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

    $curl_response = curl_exec($curl);
    curl_close($curl);

    return $curl_response;
}

You can do something like this

@Post("json")
public void someMethod(Representation rep){...}

You can substitute json for the content type you can handle.

If the post is from a simple html form then you can get the Form object from the representation and extract the parameters from that.

@Post
public void someMethod(Representation entity){
  final Form form = new Form(entity);
  String name = form.getFirstValue("name"));
}

Note you can also construct Form objects from query strings.
