contentDetails或持续时间不会使用Youtube v3 api

Question

看看这个链接,给出了一个例子

https://www.googleapis.com/youtube/v3/videos?id=7lCDEYXw3mM&key=YOUR_API_KEY
 &part=snippet,contentDetails,statistics,status

部分回应是

"contentDetails": {
    "duration": "PT15M51S",
    "aspectRatio": "RATIO_16_9"
   },

现在我想检索contentDetails或主要是持续时间.所以我打电话给

https://www.googleapis.com/youtube/v3/search?part=snippet,contentDetails&key=[API_KEY]&q=something&maxResults=15&&fields=items,nextPageToken,prevPageToken,tokenPagination

表明

{
error: {
errors: [
{
domain: "youtube.part",
reason: "unknownPart",
message: "contentDetails",
locationType: "parameter",
location: "part"
}
],
code: 400,
message: "contentDetails"
}
}

为什么？我错过了什么？如何检索视频的持续时间？

Answer 1

正如您已经发现的那样,Search:list调用不支持part参数的contentDetails.

您可以在Search:列表的参数值中包含的部件名称是id和snippet,并且那些返回非常少的数据.如果我们想要获得有关视频或视频的更具体数据,我们应该使用来自搜索的非常少的数据.

因此,要在搜索时获得视频时长,您必须拨打电话

GET https://www.googleapis.com/youtube/v3/search?part=id&q=anything&key={YOUR_API_KEY}

并从响应项中提取videoId

"id": {
"kind": "youtube#video",
"videoId": "5hzgS9s-tE8"
}

并使用它来进行视频:列表调用以获取更具体的数据

https://www.googleapis.com/youtube/v3/videos?id=5hzgS9s-tE8&key=YOUR_API_KEY&part=snippet,contentDetails,statistics,status

并从响应数据中提取持续时间

 "contentDetails": {
 "duration": "PT15M51S",
 "aspectRatio": "RATIO_16_9"
 },

Answer 2

第1步:您使用搜索列表视频ID :列表
例如,您收到3个YouTube视频ID,如:
{zOYW7FO9rzA,zOYW7FO9rzA,-vH2eZAM30s}
第2步:您必须为第二个电话放置YouTube视频ID列表.

https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=zOYW7FO9rzA,zOYW7FO9rzA,-vH2eZAM30s&key={Your API KEY} 

因此,您无需为每个视频拨打电话
.结果将是:

{
 "kind": "youtube#videoListResponse",
 "etag": "\"iDqJ1j7zKs4x3o3ZsFlBOwgWAHU/p3KyUGr7ZRowLgKTqVFixrx7-mQ\"",
 "pageInfo": {
  "totalResults": 3,
  "resultsPerPage": 3
 },
 "items": [

   "etag": "\"iDqJ1j7zKs4x3o3ZsFlBOwgWAHU/psAhg0bxv1n1IfKwXhrPMV223YE\"",
   "id": "zOYW7FO9rzA",
   "contentDetails": {

   }
  },

  },
  {

   "etag": "\"iDqJ1j7zKs4x3o3ZsFlBOwgWAHU/2BnWErqkysQERsaRNyd1ffGgJes\"",
