Restlet implementing post with json receive and response

Question

First, what i wanted to know is what i am doing is the right way to do it.

I have a scenario where i have will receive a json request and i have to update the database with that, once the db is updated i have to respond back with the json acknowledgment.

What i have done so far is create the class extending application as follows:

     @Override  
     public Restlet createRoot() {  
         // Create a router Restlet that routes each call to a  
         // new instance of ScanRequestResource.  
         Router router = new Router(getContext());  

         // Defines only one route  
         router.attach("/request", RequestResource.class);  

         return router;  
     }

My resource class is extending the ServerResource and i have the following method in my resource class

@Post("json")
public Representation post() throws ResourceException {
 try {
  Representation entity = getRequestEntity();
  JsonRepresentation represent = new JsonRepresentation(entity);
  JSONObject jsonobject = represent.toJsonObject();
  JSONObject json  = jsonobject.getJSONObject("request");

  getResponse().setStatus(Status.SUCCESS_ACCEPTED);
  StringBuffer sb = new StringBuffer();
  ScanRequestAck ack = new ScanRequestAck();
  ack.statusURL = "http://localhost:8080/status/2713";
  Representation rep = new JsonRepresentation(ack.asJSON());

  return rep;

 } catch (Exception e) {
  getResponse().setStatus(Status.SERVER_ERROR_INTERNAL);
 }

My first concern is the object i receive in the entity is inputrepresentation so when i fetch the jsonobject from the jsonrepresentation created i always get empty/null object.

I have tried passing the json request with the following code as well as the client attached

function submitjson(){ alert("Alert 1"); $.ajax({ type: "POST", url: "http://localhost:8080/thoughtclicksWeb/request", contentType: "application/json; charset=utf-8", data: "{request{id:1, request-url:http://thoughtclicks.com/status}}", dataType: "json", success: function(msg){ //alert("testing alert"); alert(msg); } }); };

Client used to call

    ClientResource requestResource = new ClientResource("http://localhost:8080/thoughtclicksWeb/request");
        Representation rep = new JsonRepresentation(new JSONObject(jsonstring));
    rep.setMediaType(MediaType.APPLICATION_JSON);
    Representation reply = requestResource.post(rep);

Any help or clues on this is hight appreciated ?

Thanks, Rahul

Answer 1

When I use the following JSON as the request, it works:

{"request": {"id": "1", "request-url": "http://thoughtclicks.com/status"}}

Notice the double quotes and additional colon that aren't in your sample.
