Question

我目前正在尝试使用Youtube V3 API生成频道中最近上传的视频的Feed。目前我的主要是正在工作，但是我不能在我的生活中获得两个重要的数据位 - 视频观看和视频持续时间。我知道这些数据属于＆＃34;视频＆＃34;端点，但我不确定如何将其集成到Google的Youtube API网站上提供的Javascript API示例中。以下是我的代码 - 非常感谢任何帮助：

// Define some variables used to remember state.
var playlistId, nextPageToken, prevPageToken;

// After the API loads, call a function to get the uploads playlist ID.
function handleAPILoaded() {
  requestUserUploadsPlaylistId();
}

// Call the Data API to retrieve the playlist ID that uniquely identifies the
// list of videos uploaded to the currently authenticated user's channel.
function requestUserUploadsPlaylistId() {
  // See https://developers.google.com/youtube/v3/docs/channels/list
  var request = gapi.client.youtube.channels.list({
    mine: true,
    part: 'contentDetails, statistics'
  });
  request.execute(function(response) {
    playlistId = response.result.items[0].contentDetails.relatedPlaylists.uploads;
    requestVideoPlaylist(playlistId);
  });
}

// Retrieve the list of videos in the specified playlist.
function requestVideoPlaylist(playlistId, pageToken) {
  $('#video-container').html('');
  var requestOptions = {
    playlistId: playlistId,
    part: 'snippet, contentDetails',
    maxResults: 10
  };
  if (pageToken) {
    requestOptions.pageToken = pageToken;
  }
  var request = gapi.client.youtube.playlistItems.list(requestOptions);
  request.execute(function(response) {
    // Only show pagination buttons if there is a pagination token for the
    // next or previous page of results.
    nextPageToken = response.result.nextPageToken;
    var nextVis = nextPageToken ? 'visible' : 'hidden';
    $('#next-button').css('visibility', nextVis);
    prevPageToken = response.result.prevPageToken
    var prevVis = prevPageToken ? 'visible' : 'hidden';
    $('#prev-button').css('visibility', prevVis);

    var playlistItems = response.result.items;
    if (playlistItems) {
      $.each(playlistItems, function(index, item) {
        displayResult(item.snippet);
        displayContentDetails(item.contentDetails);
        displayStats(item.statistics);
      });
    } else {
      $('#video-container').html('Sorry you have no uploaded videos');
    }
  });
}

// Create a listing for a video.
function displayResult(videoSnippet) {
  var title = videoSnippet.title;
  var videoId = videoSnippet.resourceId.videoId;
  var publishedAt = videoSnippet.publishedAt;
  var videoThumbURL = videoSnippet.thumbnails.high.url;
  var publishedUTC = new Date(publishedAt);
  var publishedDay = publishedUTC.getUTCDay();
  var publishedMonth = publishedUTC.getUTCMonth();
  var publishedYear = publishedUTC.getUTCFullYear();
  var a = moment(publishedUTC);
  var b = moment(Date.now());
  var timeFrom = a.from(b);
  $('#video-container').append('<a href=\"https://youtu.be/'+ videoId +'\"><li><img src='+videoThumbURL+'><br><p>' + title + ' - ' + timeFrom + '</p></li></a>');
}

// Create a listing for a video.
function displayContentDetails(stuff) {
  var videoEndsAt = stuff.duration;
  $('#video-container li').append('<span class="endsAt">'+ videoEndsAt +'</span>');
}

function displayStats(vidStats) {
  var videoStats = vidStats.viewCount;
  $('#video-container li').append('<span class="videoStats">'+ videoStats +'</span>');
}


// Retrieve the next page of videos in the playlist.
function nextPage() {
  requestVideoPlaylist(playlistId, nextPageToken);
}

// Retrieve the previous page of videos in the playlist.
function previousPage() {
  requestVideoPlaylist(playlistId, prevPageToken);
}

Answer 1

虽然您说通道代码显示您从播放列表中提取，但没有您想要的数据。

对于播放列表中的每个视频，您需要保存videoID，然后使用'snippet'的'parts'参数拨打Videos: list endpoint（一次最多50个ID）的电话，contentDetails，统计。这些API结果将包含您想要的数据。

谢谢@ Johnh10，你是对的，这就是我最终做的事情。

  var videoStatsEndpoint = "https://www.googleapis.com/youtube/v3/videos?part=statistics";
  var videoToQuery = "&id="+videoId+"&key=";
  var apiKey = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
  var videoViews = 0;
  jQuery.get(videoStatsEndpoint + videoToQuery + apiKey, function(data){
    videoViews = data.items[0].statistics.viewCount;
    console.log(videoViews);
  });

使用统计信息和持续时间数据提取YouTube视频的Feed
