为 YouTube 用户检索供稿（上传）

Question

去年有时我可以通过简单地附加/uploads?alt=rss 来检索 YouTube 用户的（可公开访问的）视频供稿。例如http://gdata.youtube.com/feeds/base/users/NTVKenya 给了http://gdata.youtube.com/feeds/base/users/NTVKenya/uploads?alt=rss。但此服务不再可用。

我猜现在推荐的方法是使用 GData 库。但是，使用此服务给了我com.google.gdata.util.NoLongerAvailableException 异常：

        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() );
        }

这给出了：

        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>

我哪里错了？

谢谢。

Answer 1

从给定 YouTube 用户获取“上传”的另一种方法是，您可以按照以下步骤操作：

1. 转到您要获取其“上传”供稿的 YouTube 频道。
2. 获取它的 channel_id - 在这里查看更多信息。
3. 将 channel_id 的第二个字符从“C”替换为“U”。示例：channel_id：UCqBJ47FjJcl61fmSbcadAVg - 修改：UUqBJ47FjJcl61fmSbcadAVg。
4. 将修改后的 channel_id 粘贴到此 URL：https://www.youtube.com/feeds/videos.xml?playlist_id=

结果将是这个 URL：

https://www.youtube.com/feeds/videos.xml?playlist_id=UUqBJ47FjJcl61fmSbcadAVg

它带来了最新上传的 15 个视频。

Answer 2

这比我想象的要难！

关键是您现在需要一个 YouTube 开发者 API 密钥。 您可以在以下位置获取钥匙： 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，我就对这里找到的新 V3 API 进行了修改： https://developers.google.com/youtube/v3/sample_requests

而且我能够构建一个似乎有效的 URL...您可能需要进一步研究和完善它。这是我尝试过的（用您的密钥替换 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：
