PATCH Anfrage mit Retrofit, zurück JSON

Question

Dies ist meine Funktion, die die Patch-Anforderung macht:

public void patchWithParams2(Integer id, JSONObject params, final JsonCallback jsonCallback){ 
    String URL = Constants.API_ENDPOINT + "/trips"; 
    RestAdapter restAdapter = new RestAdapter.Builder() 
      .setClient(new OkClient()) //very important!!! 
      .setEndpoint(URL)//base url 
      .setRequestInterceptor(new RequestInterceptor() {//You may not need to pass headers, but I do, so this is how it's done. 
       @Override 
       public void intercept(RequestInterceptor.RequestFacade request) { 
        try{ 
         String token = Utils.getEncodedAuthToken(PSLocationCenter.getInstance().pref); 
         request.addHeader("Authorization", "Basic " + token); 
         PackageInfo pInfo = context.getPackageManager().getPackageInfo(context.getPackageName(), 0); 
         request.addHeader("User-agent", "Passenger/" + pInfo.versionCode + " (" + System.getProperty("http.agent") + ")"); 
        }catch (Exception e){ 
         Log.e("","error trying to add user agent"); 
         Utils.appendLog("ERROR trying to set agent:" + e.getMessage(),true); 
        } 
        request.addHeader("Content-Type", "application/json"); 
        request.addHeader("Accept", "application/json"); 

       } 
      }) 
      .build(); 
    PatientInfoAPI patchService = restAdapter.create(PatientInfoAPI.class); 
    TripUpdate trip = new TripUpdate(); 
    trip.setNotes("#business"); 
    patchService.update(trip, String.valueOf(id), new retrofit.Callback<TripUpdate>() { 
     @Override 
     public void success(TripUpdate userUpdates, retrofit.client.Response response) { 
      Log.i("All is good", "Nickname:" + userUpdates.toString()); 
      Log.i("All is good", "Nickname:" + response.getBody().toString()); 
      BufferedReader reader = null; 
      StringBuilder sb = new StringBuilder(); 
      try { 
       reader = new BufferedReader(new InputStreamReader(response.getBody().in())); 
       String line; 

       try { 
        while ((line = reader.readLine()) != null) { 
         sb.append(line); 
        } 
       } catch (IOException e) { 
        Log.e("","error trying to get response" + e.getMessage()); 
        e.printStackTrace(); 
       } 
      } catch (IOException e) { 
       Log.e("","error trying to get response2" + e.getMessage()); 
       e.printStackTrace(); 
      } 
      String result = sb.toString(); 
      Log.i("All is good", "Nickname2:" + result); 
      jsonCallback.onResponse(null, null); 
     } 

     @Override 
     public void failure(RetrofitError error) { 
      Log.i("All is good", "Nickname:" + error.getLocalizedMessage().toString()); 
      jsonCallback.onResponse(null, null); 
     } 
    }); 
} 

ich wieder eine gültige Antwort zu bekommen, aber ich kann es zu JSON nicht analysieren. In dieser Zeit, bekomme ich folgende Fehler zurück:

try { 
        while ((line = reader.readLine()) != null) { 
         sb.append(line); 
        } 
       } catch (IOException e) { 
        Log.e("","error trying to get response" + e.getMessage()); 
        e.printStackTrace(); 
       }

Auch dies ist die Schnittstelle, die den Pfad und den Körper schafft:

public interface PatientInfoAPI { 
@PATCH("/{id}") 
public void update(@Body TripUpdate updatedDAta, @Path("id") String id, Callback<TripUpdate> response); 
} 

Ist ist posible den Körper direkt als ein Json-Objekt zu senden, und nicht aus dem Objekt?

Answer 1

die Schnittstelle gezwungen, eine JsonElement abzurufen:

 @PATCH("/{id}") 
public void update(@Body TripPatch updatedDAta, @Path("id") String id, Callback<JsonElement> response); 

Und dann so ich es bekommen:

String jsonObject = userUpdates.toString();
