API 端点 /activities 没有 return 历史活动（只能访问最近的活动）

Question

这是我可以向下滚动的最旧页面 activities.list API TEDx Talks 频道

GET https://www.googleapis.com/youtube/v3/activities?part=snippet&channelId=UCsT0YIqwnpJCM-mx7-gSA4Q&maxResults=50&pageToken=CPoBEAA&fields=items(snippet(publishedAt%2Ctitle))%2CnextPageToken%2CprevPageToken&key={YOUR_API_KEY}

响应是

{
    "prevPageToken": "CPoBEAE",
    "items": [
       {
           "snippet": {
             "publishedAt": "2017-11-21T18:30:36.000Z",
             "title": "You Are Not Who They Think You Are | Vinny McCoy | TEDxDrogheda"
           }
       },
       {
           "snippet": {
             "publishedAt": "2017-11-21T18:27:43.000Z",
             "title": "What does it mean to be authentic? | Sarah Archer | TEDxDrogheda"
           }
       },
       {
           "snippet": {
             "publishedAt": "2017-11-21T18:27:33.000Z",
             "title": "Moments in Jazz |  Jazz Quartet of the Conservatory of the Polyphonic Choir of Patras | TEDxPatras"
           }
       },
       {
           "snippet": {
             "publishedAt": "2017-11-20T20:14:23.000Z",
             "title": "Moments in Jazz |  Jazz Quartet of the Conservatory of the Polyphonic Choir of Patras | TEDxPatras"
           }
       },
       {
           "snippet": {
             "publishedAt": "2017-11-21T18:22:57.000Z",
             "title": "Adriano Teixeira | Adriano Teixeira | TEDxPassoFundo"
           }
       },
       {
           "snippet": {
             "publishedAt": "2017-11-21T18:21:50.000Z",
             "title": "Eargasm - Beat Box Act by Ivory Parker aka neXor | Ivory Parker | TEDxDonauinsel"
           }
       }
  ]    
}

你可以看到没有 nextPageToken 意味着你不能再滚动了，最旧的 activity 有

"publishedAt":  "2017-11-21T18:21:50.000Z"

同时，至少有这个视频

UPD：报告的问题案例已在 Youtube API 端修复。

Answer 1

您正在查询 activities，它返回 "kind": "youtube#activity" 的列表，您作为示例提供的项目列为 "kind": "youtube#video"。如果您使用 video 端点而不是 activities，您也会找到该项目。

更新

呼叫提供的历史活动似乎有限制。我通过指定 publishedBefore 参数成功浏览了活动。分页会让你走得更远。

例如

获取https://www.googleapis.com/youtube/v3/activities?part=snippet%2CcontentDetails&channelId=UCsT0YIqwnpJCM-mx7-gSA4Q&maxResults=50&pageToken=CGQQAA&publishedBefore=2017-10-25T18%3A21%3A50.000Z&fields=items(snippet(publishedAt%2Ctitle))%2CnextPageToken&key={YOUR_API_KEY}

显然，使用的日期可以是将来涵盖所有内容的日期。

API 端点 /activities 没有 return 历史活动（只能访问最近的活动）

API endpoint /activities doesn't return historical activities (only very recent ones are accessible)
