YouTube API 3 频道（按用户名和 ID 排列）不一致

Question

为什么当我通过ID https://www.googleapis.com/youtube/v3/channels?搜索频道时part =内容详细信息

但当我按用户名搜索时，它会返回我刚才搜索的频道IDhttps://www.googleapis.com/youtube/v3/channels?part=contentDetails

Answer 1

当我按用户名搜索时，它会返回我刚刚搜索的频道ID

您错过了通过搜索用户名或频道ID的重要部分。这是代码段的一部分，而不是contentDetails。

通过用户名：

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

通过id通道：

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

这将完全返回如下所示：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/VnicD0AYsCI7KlKKcdsmdIlWUMs\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {
   "kind": "youtube#channel",
   "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/Nl4tuuOFwuPOdHmP_Ky3vuIQ2Gg\"",
   "id": "UC_pwIXKXNm5KGhdEVzmY60A",
   "snippet": {
    "title": "CJENMMUSIC Official", <== Channel Name
    "description": "Asia's No.1 Entertainment & Media Company", <== Channel Desctiption
    "customUrl": "cjenmmusic", <=== Channel URL who has been qualified - to and for - claimed it
    "publishedAt": "2011-03-25T04:48:40.000Z",
    "thumbnails": {

     },
     "medium": {
      "url": "https://yt3.ggpht.com/-QMkGdFbhrOc/AAAAAAAAAAI/AAAAAAAAAAA/6boUKax-3EA/s240-c-k-no-mo-rj-c0xffffff/photo.jpg"
     },
     "high": {
      "url": "https://yt3.ggpht.com/-QMkGdFbhrOc/AAAAAAAAAAI/AAAAAAAAAAA/6boUKax-3EA/s240-c-k-no-mo-rj-c0xffffff/photo.jpg"
     }
    },
    "localized": {
     "title": "CJENMMUSIC Official",
     "description": "Asia's No.1 Entertainment & Media Company"
    }
   }
  }
 ]
}

如果只指向contentDetails，它将返回几乎为零：

{
 "kind": "youtube#channelListResponse",
 "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/C7SnOhT2c-Fs2R9f6JlxlOPWc34\"",
 "pageInfo": {
  "totalResults": 1,
  "resultsPerPage": 1
 },
 "items": [
  {
   "kind": "youtube#channel",
   "etag": "\"uQc-MPTsstrHkQcRXL3IWLmeNsM/3RTKaEQC9GX8c58R2Bhd8G1y3zM\"",
   "id": "UC_pwIXKXNm5KGhdEVzmY60A",
   "contentDetails": { <============== detail contents
    "relatedPlaylists": {
     "uploads": "UU_pwIXKXNm5KGhdEVzmY60A",
     "watchHistory": "HL",
     "watchLater": "WL"
    }
   }
  }
 ]
}

Answer 2

当我按ID搜索频道时..我没有收到退货。

尝试一下channels.list的尝试部分。我可以使用以下参数获取JSON响应：

 part->contentDetails
 id-> yourchannel ID

Authorize and Execute

它返回的响应一点也不空。

{
 "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": ""
    }
   }
  }
 ]
}

这对我来说是很多结果。

但是当我按userName搜索时，它会返回我刚刚搜索的频道ID。

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

关于< code>forUsername参数的附加说明是，它用于使用API的v3将您的任意传统Youtube用户名(即旧的YouTube帐户)转换为频道ID。更多信息请参阅《使用频道id》指南。
