使用Youtube Data API的频道：带有brandingSettings部分的列表在使用id过滤器时有效，但对我来说不使用forUsername过滤器。
例如，GET https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&forUsername=h3h3Productions&key={YOUR_API_KEY}会导致以下内容，缺少brandSettings:
{
"kind": "youtube#channelListResponse",
"etag": ""0KG1mRN7bm3nResDPKHQZpg5-do/Qagk6ayL_umilQ398UZyAHwxK_g"",

}
]
}
但是GET https://www.googleapis.com/youtube/v3/channels?part=brandingSettings&id=UCDWIvJwLJsE4LG1Atne2blQ&key={YOUR_API_KEY}（您会注意到它使用了同一用户的ID）保持原样：

我做错什么了吗？保持一切不变，但将零件切换到snippet或statistics，在这两种情况下都会如您所期望的那样工作。我也在其他几个频道上尝试过，得到了同样的结果。
我认为这是按预期工作的。请参阅YouTube API-不返回按用户名查询的频道品牌设置。Tl；dr：尽管你可以通过使用频道的用户名来寻找频道，但从V2的迁移带来了一个事实，即并非每个YouTube频道都有一个唯一的用户名，所以这就是为什么当你使用频道ID（它是唯一的）时它能正确工作。我还通过指定forMine而不是通道ID进行了尝试，结果不出所料。
