GSON解析与改型解析Flickr JSON响应

Question

其答复如下：

 jsonFlickrApi({"photos":{"page":1,"pages":130008,"perpage":2,"total":"260016","photo":[{"id":"15817874286","owner":"36687364@N07","secret":"e480e6fe0c","server":"7475","farm":8,"title":"3D visualisatie","ispublic":1,"isfriend":0,"isfamily":0},{"id":"15817785516","owner":"36687364@N07","secret":"132f12dff1","server":"7496","farm":8,"title":"schetsontwerp","ispublic":1,"isfriend":0,"isfamily":0}]},"stat":"ok"})

我相信问题出在响应前面的jsonFlickrApi上。

执行以下代码时：

    @GET("/rest/")
void getPhotos(@Query("method") String method,@Query("api_key") String apiKey,@Query("tags") String tags,@Query("per_page")String perPage,@Query("format") String format, Callback<FlickrResult> data);

flickerRestAPI.getPhotos("flickr.photos.search","2ef592bfddc86f508550184ec706a2fc","gent","10","json",new Callback<FlickrResult>() {
        @Override
        public void success(FlickrResult photos, Response response) {
            Log.i(TAG, " " + photos.toString());
        }

        @Override
        public void failure(RetrofitError error) {
            Log.e(TAG,"Failed");
            Log.e(TAG," " +error.getUrl());
            Log.e(TAG," "+error.getMessage());

        }
    });
}

只需添加nojsoncallback参数

https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=2ef592bfddc86f508550184ec706a2fc&tags=gent&per_page=2&format=json&nojsoncallback=1
