Question

有时去年我只需添加http://gdata.youtube.com/feeds/base/users/NTVKenya即可为YouTube用户检索（可公开访问的）视频供稿。例如http://gdata.youtube.com/feeds/base/users/NTVKenya/uploads?alt=rss给了com.google.gdata.util.NoLongerAvailableException。但是这项服务已不再可用。

现在推荐的方法是使用GData库。但是，使用此服务会给我YouTubeService service = new YouTubeService("service"); ArrayList<String> urls = new ArrayList<String>(); VideoFeed videoFeed = service.getFeed(new URL('http://gdata.youtube.com/feeds/base/users/NTVKenya'), VideoFeed.class); for (VideoEntry videoEntry : videoFeed.getEntries() ) { urls.add( videoEntry.getHtmlLink().getHref() ); }例外：

        com.google.gdata.util.NoLongerAvailableException: No longer available
        <errors xmlns='http://schemas.google.com/g/2005'><error><domain>GData</domain><code>NoLongerAvailableException</code><internalReason>No longer available</internalReason></error></errors>

这给出了：

private static void Save<T>(IQueryable<T> items, IList<IDataWriter> dataWriters, IEnumerable<PropertyColumn> columns) where T : MyTableClass
{
    int pageSize = 500; //Only 500 records will be loaded.
    int currentStep = 0;
    while (true)
    {
         //Here we create a new request into the database using our filter.                
         var tempList = items.Where(yourFilter).Skip(currentStep * pageSize).Take(pageSize);
         foreach (var item in tempList)
         {
            //If you have an exception here maybe something wrong in your dataWriters or columns.
         }
         currentStep++;
         if (tempList.Count() == 0) //No records have been loaded so we can leave.
             break;
    }
}

我哪里错了？

感谢。

这比我想象的要难！

关键是你现在需要一个YouTube开发者API密钥。你可以获得你的钥匙： https://console.developers.google.com

一旦我创建了一个应用程序并获得了我的密钥，我就在这里找到了新的V3 API： https://developers.google.com/youtube/v3/sample_requests

我能够构建一个似乎有用的URL ...您可能需要进一步研究和完善它。这是我尝试过的（用你的密钥替换MYAPIKEYHERE）： https://www.googleapis.com/youtube/v3/search?part=snippet&q=NTVKenya&order=viewCount&type=video&key=MYAPIKEYHERE

这是它返回的内容：
