带有 API v3 的 Youtube 视频标题没有 API key ？

Question

是否可以通过 API v3 使用视频 ID 获取视频标题？没有 API key ？我在 API 文档中找不到任何获取标题的信息或示例。

Answer 1

这正是 的含义。 o嵌入 协议(protocol)。

oEmbed is a format for allowing an embedded representation of a URL on third party sites. The simple API allows a website to display embedded content (such as photos or videos) when a user posts a link to that resource, without having to parse the resource directly.
