使用 Google Apps 脚本插入 YouTube 顶级评论

我正在尝试使用 Google Apps 脚本创建一个程序，该程序会在某个 YouTube 频道上传时插入评论。我已经能够从频道获取最新的 YouTube 视频 ID，但是当我尝试插入评论时，它会抛出错误“解析错误（第 19 行，文件‘代码’）”。

19号线：YouTube.CommentThreads.insert("snippet", {

这是我的代码：

function getVideo() {
  // MrBeast Channel ID: UCX6OQ3DkcsbYNE6H8uQQuVA
  var channel = "UCX6OQ3DkcsbYNE6H8uQQuVA";
  var fttx = "FIRST!";
  var results = YouTube.Channels.list("contentDetails", {"id": channel});
  for (var i in results.items) {
    var item = results.items[i];
    var playlistId = item.contentDetails.relatedPlaylists.uploads;
    // Uploads Playlist ID: UUX6OQ3DkcsbYNE6H8uQQuVA
    var playlistResponse = YouTube.PlaylistItems.list("snippet", {"playlistId": playlistId, "maxResults": 1});
    for (var j = 0; j < playlistResponse.items.length; j++) {
      var playlistItem = playlistResponse.items[j];
      var latvid = playlistItem.snippet.resourceId.videoId;
      comment(latvid, channel, fttx);
    }
  }
}
function comment(vid, ytch, fc) {
  YouTube.CommentThreads.insert("snippet", {
    "snippet.channelId": ytch,
    "snippet.videoId": vid,
    "snippet.topLevelComment.snippet.textOriginal": fc
  });
}

Per Apps Script advanced services documentation, when specifying resources (such as a CommentThread) they are the first parameter to a method. If you use the Apps Script editor's autocomplete, it is very clear about the required order:

另请注意，您错误地创建了资源主体 - 您有各种子属性。例如，snippet财产是必需的成员CommentThread资源. Three "snippet.___"属性不等于一个snippet具有 3 个子属性的属性。

因此解决解析错误的解决方案YouTube.CommentThreads.insert是使用所需的方法签名，以及所需的资源格式：

function startCommentThread(vid, ytch, fc) {
  const resource = {
    snippet: {
      channelId: ytch,
      videoId: vid,
      topLevelComment: {
        snippet: {
          textOriginal: fc
        }
      }
    }
  };
  YouTube.CommentThreads.insert(resource, "snippet");
}
