我正在尝试使用 youtube gdata api for java 进行一些搜索，但我遇到了一些错误。
我设置了最大值。结果到 20 并开始进行测试搜索，偶尔没有结果返回。
然后我开始一一搜索，我注意到一些单一的搜索结果有问题，当我设置最大值时。结果到了20个，连一个结果有问题都没有结果。
堆栈跟踪是：

我对此进行了一些研究，我注意到在旧版本的 gdata youtbe api 中存在此问题，但可以通过以下解决方法解决：
临时解决方法是复制 com.google.gdata.data.youtube.YtPublicationState 的源并添加如下所示的受限类型。然后在类路径中将其添加到更高的位置。公共静态枚举状态{
/**
* The video has not been completely defined yet, but it's been stored
* already.
* Either the video data or the description is missing.
*/
INCOMPLETE,
/** The video has just been uploaded and is not yet publicly available. */
PROCESSING,
/** The video has been rejected. */
REJECTED,
/** The video was not successfully processed. */
FAILED,
/** Video was removed by the owner. */
DELETED,
RESTRICTED,
;
}
但我使用的是最新版本的 gdata-src.java-1.47.1 版本。我有罐子：
gdata-core-1.0.jar
gdata-youtube-2.0.jar
gdata-youtube-meta-2.0.jar
gdata-client-1.0.jar
gdata-client-meta-1.0.jar
gdata-media-1.0.jar
番石榴-11.0.2.jar jsr305.jar
邮件.jar
我检查了源代码中的 YtPublicationState 并且枚举状态具有 RESTRICTED 元素。
但我仍然得到例外。
我得到异常的源代码是：
public VideoFeed Search(String criteria, int maxResults, int startIndex)
{
try
{
YouTubeQuery youtubeQuery = new YouTubeQuery(new URL("http://gdata.youtube.com/feeds/api/videos"));
youtubeQuery.setFullTextQuery(criteria);
youtubeQuery.setMaxResults(_maxResults);
youtubeQuery.setStartIndex(_startIndex);
VideoFeed videoFeed = _youtubeService.query(youtubeQuery, VideoFeed.class);
return videoFeed;
} catch (IOException ex)
{
Logger.getLogger(GdataYoutube.class.getName()).log(Level.SEVERE, null, ex);
} catch (ServiceException ex)
{
Logger.getLogger(GdataYoutube.class.getName()).log(Level.SEVERE, null, ex);
}
return null;
}
任何人都知道如何修复它或任何替代方法？（我想一一获得结果并在服务器上自行消除损坏的结果，但它会产生很多通信开销。）
