Ошибка запроса синтаксического анализа JSON в Foursquare API Java, запущенном на конечных точках Google Cloud

Я использовал код [1] и реализовал его в конечных точках Google Cloud (поскольку я не могу использовать org.json, я скопировал код [2]), но у меня возникла ошибка, когда синтаксический анализ запроса дает мне исключение JSON поля ["icon"].

[1] https://code.google.com/p/foursquare-api-java/ [2] https://github.com/douglascrockford/JSON-java

Вот мой код:

@ApiMethod(name = "searchVenues")
public List<Api> searchVenues(@Named("ll")String ll) throws FoursquareApiException, CiudadAppoyoApiException {


    //ll="6.5589393,-73.1290595";

    List<Api> venuesList = new ArrayList<Api>();

    // First we need a initialize FoursquareApi.
        FoursquareApi foursquareApi = new FoursquareApi("Client ID", "Client Secret", "Callback URL");
        Result<VenuesSearchResult> result = foursquareApi.venuesSearch(ll, null, null, null, null, null, null, null, null, null, null, null, null);

        if (result.getMeta().getCode() == 200) {

            // if query was ok we can finally we do something with the data

            for (CompactVenue venue : result.getResult().getVenues()){
                Api venuesObj = new Api();
                System.out.println(venue.getName());
                venuesObj.setVenue(venue);
                venuesObj.setFoursquareId(Long.getLong(venue.getId()));
                venuesList.add(venuesObj);
            }

            return venuesList;
        } else {
            if (result.getMeta().getCode() == 400) throw new CiudadAppoyoApiException("Request no valido");
            if (result.getMeta().getCode() == 404) throw new CiudadAppoyoApiException("Ningún resultado");
            if (result.getMeta().getCode() == 500) throw new CiudadAppoyoApiException("Error en el servidor");
            return venuesList;
        }

}

При просмотре документа Foursquare API «значок» не отображается в качестве возвращаемого значения.

Я использую тот же Java Foursquare API, и мне пришлось проверить его и внести в него множество изменений, чтобы он соответствовал текущей спецификации.

Я предлагаю взглянуть на класс VenuesSearchResult и посмотреть, есть ли там ссылка на значок.

Спасибо, я нашел только частные площадки CompactVenue []; частные группы VenueGroup []; частный геокод GeoCode; Я добавил комментарий к методу отлова, но все же работал, но я не думаю, что это отличное решение - person contreras; 14.01.2015
