Retrieve Video IDs contained in a Playlist-YouTube API v3

(Retrieve Video IDs contained in a Playlist - YouTube API v3)

发布于 2015-06-04 20:09:27

我一直在使用以下方法来检索特定YouTube播放列表中包含的所有视频ID，标题和默认缩略图，以便在动态播放列表轮播中使用（然后将ID传递到用于动态创建缩略图的数组中请注意，“播放列表”变量是通过外部XML值定义的）：

// Get YouTube Playlist values
var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/' + playlist + '?v=2&alt=json&callback=?';
var videoURL = 'http://www.youtube.com/watch?v=';
$.getJSON(playListURL, function(data) {
var list_data = "";
$.each(data.feed.entry, function(i, item) {
    var feedTitle = item.title.$t;
    var feedURL = item.link[1].href;
    var fragments = feedURL.split("/");
    var videoID = fragments[fragments.length - 2];
    var thumb = ""+ videoID +"/sddefault.jpg";
    if (videoID !='videos') {
        yt_videos.push(videoID);
    }
    yt_thumb.push(thumb);
    yt_title.push(feedTitle);
});
$(list_data).appendTo(".cont");
populateCarousel();
});

YouTube已取消了v1-2 API的使用，并且该方法不再有效。YouTube API v3是否提供等效的方法？具体替换通话：

var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/' + playlist + '?v=2&alt=json&callback=?';

你将需要切换到新的PlaylistItems / list端点，才能从播放列表中获取视频信息。

要求：

HTTP GET: GET https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2C+id&playlistId=PLCJLiJ8uSJrCpxwz4lmnz1NvvF2SzXbhk&key={YOUR_API_KEY}

响应（针对id= PLCJLiJ8uSJrCpxwz4lmnz1NvvF2SzXbhk）：

在id针对每个对象值items数组应该是videoId你想要的价值。

实际上，这些ID似乎不是视频ID：/您不能像获取播放列表项ID一样使用它https://www.youtube.com/watch?v={{video_id}}，实际上您会在item.index.contentDetails.videoId节点中找到您的ID

如何获取带有播放列表ID和索引号的视频详细信息？

auX 2021-01-02 23:27:19

来晚了，碰到了一个相同的问题：items.id表示播放列表项的ID，而不是视频（播放列表项是嵌入视频的容器）。对于视频ID，只需使用items.snippet.resourceid.videoId
