YouTube API 文本显示对于所有评论都是空白的

Question

我们有一个网站，几个月来一直在使用 YouTube API 为视频加载评论，没有问题。 本周末，我们注意到所有视频中所有评论的评论文本都消失了！ 作者信息，publishdAt等都很好，但是片段.textDisplay对于每条评论都是空白的。 如果我在 YouTube.com 上观看视频，评论很好。

示例 API 网址：https://www.googleapis.com/youtube/v3/commentThreads?videoId=1nFywcC37i0&key=PRIVATE_KEY&part=snippet,replies

部分 JSON 返回：

Answer 1

它似乎确实是最近的错误;我将在 http://code.google.com/p/gdata-issues/issues/detail?id=7969 密切关注该报告，并实施解决方法以现在使用textFormat作为纯文本。

Answer 2

如果需要 textFormat html，可以通过请求注释列表来接收注释。将筛选器 ID 设置为在注释线程列表响应中找到的顶级注释的 id。
