YouTube API 3 频道的用户名和 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] 搜索频道时，我没有返回任何项目。

但是当我按用户名搜索时，它会返回我刚刚搜索的频道 ID https://www.googleapis.com/youtube/v3/channels?part=contentDetails&forUsername=washingtonstateuniv&key=[YOUR_API_KEY]

Answer 1

当我按 ID 搜索频道时......我没有返回任何项目。

试试Try-it section for channels.list。我可以使用这些参数获取 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}",

     },

     },
     "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": ""
    }
   }
  }
 ]
}

这对我来说是很多结果。

但是当我按用户名搜索时，它会返回我刚才的频道 ID 搜索。

在上面的 channels.list try-it 文档中，forUsername 被定义为 forUsername 参数指定 YouTube 用户名，从而请求与该用户名关联的频道。所以我认为它正在做它的工作。

forUsername 参数的附加说明是，它用于使用 API 的 v3 将您的任意旧 YouTube 用户名（即旧 Youtube 帐户）转换为频道 ID。更多内容请参见 Work with Channel IDs 指南。

当我按用户名搜索时，它会返回我刚刚输入的频道 ID 搜索了

您错过了通过forUsername 或channelID 搜索的重要部分。那是 sn-p 部分，而不是 contentDetails。

forUsername：

 https://www.googleapis.com/youtube/v3/channels?&part=snippet,id&forUsername=RealMiBs&title&key={YOUR_API_KEY}

id频道：

https://www.googleapis.com/youtube/v3/channels?&part=snippet,id&id=UC_pwIXKXNm5KGhdEVzmY60A&title&key={YOUR_API_KEY}

这将完全返回如下：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/VnicD0AYsCI7KlKKcdsmdIlWUMs\"",
 "pageInfo": {

     },

     "description": "Asia's No.1 Entertainment & Media Company"
    }
   }
  }
 ]
}

如果你只是指向contentDetails，它会返回几乎什么都没有：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/C7SnOhT2c-Fs2R9f6JlxlOPWc34\"",
 "pageInfo": {

   "id": "UC_pwIXKXNm5KGhdEVzmY60A",
   "contentDetails": { <============== detail contents
    "relatedPlaylists": {
     "uploads": "UU_pwIXKXNm5KGhdEVzmY60A",
     "watchHistory": "HL",
     "watchLater": "WL"
    }
   }
  }
 ]
}
