我的信息缩略图是一个对象，如果是，那么我将如何获取 URL？因为我想用缩略图做一个嵌入，

let info = ytdl.getInfo(url);
let song = {
.
.
.
thumbnail: info.videoDetails.thumbnail
}

let embed = new Discord.MessageEmbed()
.setTitle('title')
.setThumbnail(*Place the url here*);

//But I can't because ytdl.videoDetails.thumbnail is an Object

我也试过 ytdl.thumbnail_url 但它总是返回未定义。我该如何解决？

编辑：我找到了解决方案，我做了一个解析信息的函数，我做了 resolve.videoDetails.thumbnail.thumbnails[0]，但我的问题是所有缩略图数组有什么区别？它的输出是这样的：

如果您想从缩略图对象中获取缩略图网址，您可以使用JSON.stringify

像这样：指定您想要第一个缩略图（有多个不同大小的缩略图）JSON.stringify(info.videoDetails.thumbnail.thumbnails[0]); 。[0]之后您可能会弄清楚如何获取网址。
