在列出播放列表项时返回持续时间

Question

我使用这个url:

https://www.googleapis.com/youtube/v3/playlistItems?
    playlistId=FLFe0SGNFqZ9E2owO5ZDZpeg&
    part=snippet,contentDetails,status

获取YouTube播放列表。

我包含了所有我感兴趣的part，但是我没有办法返回项目的duration。

https://developers.google.com/youtube/v3/docs/playlistItems/list

这可能吗?

目前我只得到这样一个项目:

{
  "status": {
    "privacyStatus": "public"
  }, 
  "kind": "youtube#playlistItem", 
  "contentDetails": {
    "videoId": "tL-Ba86UhoE"
  }, 
  "snippet": {
    "playlistId": "FLFe0SGeFqZ9E2owO5ZDZpwg", 
    "thumbnails": {
      "default": {
        "url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/default.jpg", 
        "width": 120, 
        "height": 90
      }, 
      "high": {
        "url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/hqdefault.jpg", 
        "width": 480, 
        "height": 360
      }, 
      "medium": {
        "url": "https://i1.ytimg.com/vi/tL-BA86Uhoh/mqdefault.jpg", 
        "width": 320, 
        "height": 180
      }
    }, 
    "title": "Music Video", 
    "resourceId": {
      "kind": "youtube#video", 
      "videoId": "tL-BA86Uhoh"
    }, 
    "channelId": "UCFe0SGNFqZ9E2owO5ZDZpwg", 
    "publishedAt": "2013-07-06T18:41:43.000Z", 
    "channelTitle": "channeltitle", 
    "position": 0, 
    "description": "Video for"
  }, 
  "etag": ""ePFRUfYBkeQ2ncpP9OLHvB0fDw4/CJiCG6tvFw4quQlzJq3gTrhvCNo"", 
  "id": "FL-fX6VqgtTfCJWKNE4aVRODKSrRgEdGvw"
}, 

完全没有时间指示。我宁愿避免在YouTube上充斥返回单个视频持续时间的请求。

Answer 1

使用这样的链接来获取许多视频的持续时间:

https://www.googleapis.com/youtube/v3/videos?part=contentDetails&id=idFirst,idSecond&key=YOUR_API_KEY

Answer 2

使用此函数:[仅用于Youtube Api v3]

浏览器:

你必须发出另一个HTTP请求使用:

https://www.googleapis.com/youtube/v3/videos?id={video id}∂contentDetails&key={api key}

and on

contentDetails

你会发现持续时间

Php:

function getDuration($apiKey,$video_id){        
    $link='https://www.googleapis.com/youtube/v3/videos?id='.$video_id.'&part=contentDetails&key='.$apiKey;
    $data = json_decode(file_get_contents($link),true);
    $duration =  $data['items'][0]['contentDetails']['duration'];   
    return $duration;
 }
