google-apps-script - 调用YOUTUBE视频API时无法获得视频时长

Question

我调用YT搜索API，然后获取每个视频结果的完整数据(视频API)。
但是，我无法获得每个视频的时长。
我收到一个未定义的错误:

  var videoResultsFullData = YouTube.Videos.list('id,snippet', { id : searchResults.map(item => item.id.videoId)})
    var popularChannelIds = YouTube.Channels.list('id,snippet, statistics', {
         id: resultsParentChannelIds
    }).items.filter(ch => ch.statistics.subscriberCount > sh.getRange("D24").getValue() ).map(channel => channel.id);
   
    // .filter(video => popularChannelIds.includes(item.id.channelId));

    var videoPopularResultsFullData = 
    videoResultsFullData.getItems()
    .filter(video => popularChannelIds.includes(video.snippet.channelId));
// };


var range = 3;
for (var i in videoPopularResultsFullData) {
    var item = videoPopularResultsFullData[i];
    var temp = item.getContentDetails().duration;

Answer 1

我认为在您的情况下，需要在contentDetails中包含part。那么下面的修改呢？
从:

var videoResultsFullData = YouTube.Videos.list('id,snippet', { id : searchResults.map(item => item.id.videoId)})

至:

var videoResultsFullData = YouTube.Videos.list('id,snippet,contentDetails', { id : searchResults.map(item => item.id.videoId)})

或者，您也可以将part用作数组，如下所示。

var videoResultsFullData = YouTube.Videos.list(["id","snippet","contentDetails"], { id : searchResults.map(item => item.id.videoId)})
