Youtube 频道列表brandingSettings 为空，forUsername 但不是 id

Question

在使用id 过滤器但不适用于我的forUsername 过滤器时，将Youtube Data API's Channels:list 与brandingSettings 部分一起使用。

例如，GET https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&forUsername=h3h3Productions&key={YOUR_API_KEY} 的结果如下，缺少brandSettings：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"0KG1mRN7bm3nResDPKHQZpg5-do/Qagk6ayL_umilQ398UZyAHwxK_g\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 5
 },
 "items": [
  {
   "kind": "youtube#channel",
   "etag": "\"0KG1mRN7bm3nResDPKHQZpg5-do/tTzKQvYs0Y2GpqN2wqgudxB2TnQ\"",
   "id": "UCDWIvJwLJsE4LG1Atne2blQ"
  }
 ]
}

但是GET https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&id=UCDWIvJwLJsE4LG1Atne2blQ&key={YOUR_API_KEY}（你会注意到它使用了同一个用户的ID）保持原样：

我做错了吗？保持一切不变，但将部分切换到 snippet 或 statistics 在这两种情况下都符合您的预期。我还在其他几个频道上进行了尝试，得到了相同的结果。

Answer 1

我认为这是按预期工作的。见YouTube API - No channel branding settings returned for queries by username。 Tl;dr：即使您可以使用他们的用户名来查找频道，但从 V2 的迁移带来了一个事实，即并非每个 YouTube 频道都有唯一的用户名，因此当您使用频道 ID（即独特）。我还通过指定 forMine 而不是频道 ID 进行了尝试，它按预期工作。
