GSON解析與改造解析Flickr JSON響應

我似乎有以下問題。我正在使用retrofit來獲取JSON文件並將其解析爲java對象。GSON解析與改造解析Flickr JSON響應

我考慮的網址是： https://api.flickr.com/services/rest/?method=flickr.photos.search&api_key=2ef592bfddc86f508550184ec706a2fc&tags=gent&per_page=2&format=json

與回覆：

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

我認爲，問題出在jsonFlickrApi在響應的前面。

當執行以下代碼：

@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);

和

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()); 

     } 
    }); 
}

我得到

我使用的包裝類：

public class FlickrResult { 

@SerializedName("photos") 
public FlickrPhotos photos;

}

public class FlickrPhotos { 

public int page; 
public String pages; 
public int perpage; 
public String total; 
public ArrayList<FlickrPhoto> photo; 
public String stat;} 

public class FlickrPhoto { 


public String id; 
public String owner; 
public String secret; 
public String server; 
public int farm; 
public String title; 
public int ispublic; 
public int isfriend; 
public int isfamily;}
