youtube - YouTube API 3 channel 的用户名和ID不一致

Question

为什么当我通过ID https://www.googleapis.com/youtube/v3/channels?part=contentDetails&id=UU-tdS40X5ld-a4KfarLJuDw&key=[YOUR_API_KEY]搜索 channel 时，没有返回任何项目。

但是当我通过userName搜索时，它将返回我刚刚搜索https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=washingtonstateuniv&key=[YOUR_API_KEY]的 channel ID

Answer 1

when I search for a channel by ID .. I get no items returned.

尝试使用 Try-it section的channels.list。我可以使用以下参数来获取JSON响应:

 part->contentDetails
 id-> yourchannel ID

Authorize and Execute

它返回的响应根本不是空的。

{
 "kind": "youtube#channelListResponse",
 "etag": "\"I_8xdZu766_FSaexEaDXTIfEWc0/FiuYcDu7WFmoFVcLDRvENYGl_tQ\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {

   "kind": "youtube#channel",
   "etag": "\"I_8xdZu766_FSaexEaDXTIfEWc0/QjMybH99xT3x-znrh2Yerx_0DWk\"",
   "id": "{my channel id}",
   "snippet": {
    "title": "{my channel name}",
    "description": "",
    "publishedAt": "2011-10-10T15:30:40.000Z",
    "thumbnails": {
     "default": {
      "url": "https://yt3.ggpht.com/-EN5H1HDHqIU/ABCDEFGHIJK/ABCDEFGHIJK/l2gqeYg94P8/s88-c-k-no-mo-rj-c0xffffff/photo.jpg"
     },
     "medium": {
      "url": "https://yt3.ggpht.com/-EN5H1HDHqIU/ABCDEFGHIJK/ABCDEFGHIJK/l2gqeYg94P8/s240-c-k-no-mo-rj-c0xffffff/photo.jpg"
     },
     "high": {
      "url": "https://yt3.ggpht.com/-EN5H1HDHqIU/ABCDEFGHIJK/ABCDEFGHIJK/l2gqeYg94P8/s240-c-k-no-mo-rj-c0xffffff/photo.jpg"
     }
    },
    "localized": {
     "title": "{my channel name}",
     "description": ""
    }
   }
  }
 ]
}

对我来说，这是很多结果。

But when I search by userName, it returns the channel ID that I just searched for.

在上面的channels.list try-it文档中， forUsername定义为 forUsername参数指定YouTube用户名，从而请求与该用户名关联的 channel 。因此，我认为它正在发挥作用。

有关 forUsername参数的附加说明是，它用于使用API​​的v3将您的任意旧版YouTube用户名(即旧的YouTube帐户)转换为 channel ID。 Work with Channel IDs指南中有更多内容。
