Question

我有以下代码，我认为使用已弃用的YouTube API v2，以便检索和显示播放列表。它工作了几个星期，现在已经停止了 - 如果这是问题，是否有API v3方法可以做到这一点？

<script type="text/javascript">
var playListURL = 'http://gdata.youtube.com/feeds/api/playlists/PLCJLiJ8uSJrCpxwz4lmnz1NvvF2SzXbhk&alt=json&callback=?&max-results=50';
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 pubdate  = item.media$group.yt$uploaded.$t;
        var fulldate = new Date(pubdate).toLocaleDateString();
        var feedURL = item.link[1].href;
        var fragments = feedURL.split("/");
        var videoID = fragments[fragments.length - 2];
        var url = videoURL + videoID;
        var thumb = "http://img.youtube.com/vi/"+ videoID +"/mqdefault.jpg";
        list_data += '<li><a href="'+ url +'" title="'+ feedTitle +'"><img alt="'+ feedTitle+'" src="'+ thumb +'"</a><br /><a href="'+ url +'" title="'+ feedTitle +'"><strong>'+ feedTitle+'</strong></a><br />'+ fulldate +'</li>';
        console.log(item);
    });
    $(list_data).appendTo(".cont");
});
</script>
<ul class="cont" id="double">
</ul>

Answer 1

YouTube v2 API已弃用，无法再使用。您将要使用新的PlaylistItems/list端点从播放列表中获取视频信息。

要从您指定的播放列表中获取视频，请尝试更改您的GET请求：

请求：

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

像往常一样解析JSON。

使用JSON嵌入YouTube播放列表 - 停止工作
