在Google Cloud Endpoints上运行的Foursquare API Java上发生错误JSON解析请求

I used the code [1] and I've implemented in Google Cloud Endpoints (since I can't use org.json I copied the code [2]), but I've an error when parse the request gives me a JSON exception of the ["icon"] field.

我使用了代码[1]并且我在Google Cloud Endpoints中实现了（因为我无法使用org.json我复制了代码[2]），但是在解析请求时我遇到了一个错误，给了我一个JSON异常[“icon”]字段。

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

Here is my code:

这是我的代码：

@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;
        }

}

Here are the logs

Looking at the Foursquare API doco 'icon' isn't listed as a return value.

查看Foursquare API doco'icon'未列为返回值。

I use the same Java Foursquare API and had to check it out and make a lot of changes to it to enable it to be valid with the current spec.

我使用相同的Java Foursquare API并且必须检查它并对其进行大量更改以使其对当前规范有效。

My suggestion is to take a look at the VenuesSearchResult class and see if there is a reference to icon in there.

我的建议是看看VenuesSearchResult类，看看那里是否有对图标的引用。
