基本上，我想检查现在是否有多个 channel 正在流式传输而不使用 Search.list。
我使用了来自 youtube 数据 API 的 Search.list enter link description here ，但我发现这种方法真的很昂贵。如页面所述，“调用此方法的配额成本为 100 个单位。”因此每天都非常容易达到限制。
我搜索了数小时以找到另一种可以提供特定 channel 直播状态的方法。一定是我漏掉了什么，因为当我进入一个 channel 时，我可以很容易地知道这个 channel 现在是否正在播放或有任何直播计划。我认为这将是 channel 的属性(property)。
但是，我没有找到任何相关的方法。当我调用 Channels.list() 时，我可以在“items.contentDetails.relatedPlaylists.uploads”中找到上传的视频作为播放列表，但没有直播信息。
我想出的唯一解决方案是请求页面 https://www.youtube.com/channel/channel_id/live并检查它是否包含“离线”，但我认为使用他们自己的 API 可能更好。
最佳答案
您还可以使用 playlistItems.list请求从当前正在直播的 channel 中检索视频。
tl;dr:使用 YouTube Live channel 中可用的任何直播播放列表网站。选择您感兴趣的直播播放列表后，使用 playlistItems.list用于从选定的播放列表中检索直播视频。
您需要按照以下步骤选择直播播放列表并使用 YouTube 数据 API 发出请求 playlistItems.list用于从选定的播放列表中检索直播视频:
- 输入Live channel - 根据其描述:
Description
YouTube Live - Watch great live streams, such as live gaming, live music, live sports, live news, and Google Hangouts.
- 在“直播” channel 的主页中，您会看到各种直播事件(包含在
播放列表中)，例如:
Live Now: Which in my opinion it contains all current livestream events in YouTube (independent of its live streaming category), and the live stream playlist I'll use in this demonstration.
- 选择直播播放列表后，使用 playlistItems.list请求从选定的直播播放列表中检索视频。
从给定播放列表中检索视频的 playlistItems.list 请求如下:
GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2C+contentDetails&playlistId=PLU12uITxBEPFJz2brJ8C8IBst7O5fHgJ5&fields=etag%2CeventId%2Citems%2Ckind%2CnextPageToken%2CpageInfo%2CprevPageToken%2CtokenPagination%2CvisitorId&key={YOUR_API_KEY}
在这种情况下，如果我在 Google API Explorer demo 中执行此请求，结果将包含来自拉丁美洲的直播视频。
N.B, the results may vary from region.
