改型返回LinkedTreeMap而不是JSON

Question

我正在使用Reverfit 2.0从返回json文本的web服务读取数据，但在下面的代码中响应是LinkedTreeMap，我无法将其转换为json：

public interface GeoAPIInterface {
    String ENDPOINT = "http://www.geoplugin.net/";

    @GET("json.gp")
    Call<Object> getIP(@Query("ip") String ip);
}

现在我从站点读取数据：

Retrofit retrofit = new Retrofit.Builder()
         .baseUrl(GeoAPIInterface.ENDPOINT)
         .addConverterFactory(GsonConverterFactory.create())
         .build();
GeoAPIInterface inBankAPI = retrofit.create(GeoAPIInterface.class);
Call<Object> call=inBankAPI.getIP("8.8.8.8");
call.enqueue(new Callback<Object>() {
    @Override
    public void onResponse(Response<Object> response, Retrofit retrofit) {
        Log.d("App","");
    }

    @Override
        public void onFailure(Throwable t) {
            Log.d("App","error!");
    }
});

形成的url为http://www.geoplugin.net/json.gp？ip=8.8.8.8json响应为

{
  "geoplugin_request":"8.8.8.8",
  "geoplugin_status":200,
  "geoplugin_credit":"Some of the returned data includes GeoLite data created by MaxMind, available from <a href=\\'http:\/\/www.maxmind.com\\'>http:\/\/www.maxmind.com<\/a>.",
  "geoplugin_city":"Mountain View",
  "geoplugin_region":"CA",
  "geoplugin_areaCode":"650",
  "geoplugin_dmaCode":"807",
  "geoplugin_countryCode":"US",
  "geoplugin_countryName":"United States",
  "geoplugin_continentCode":"NA",
  "geoplugin_latitude":"37.386002",
  "geoplugin_longitude":"-122.083801",
  "geoplugin_regionCode":"CA",
  "geoplugin_regionName":"California",
  "geoplugin_currencyCode":"USD",
  "geoplugin_currencySymbol":"&#36;",
  "geoplugin_currencySymbol_UTF8":"$",
  "geoplugin_currencyConverter":1
}
