【中文标题】使用 alt=json-in-script&callback 检索 info V3 youtube API

【英文标题】：Retrieve info V3 youtube API with alt=json-in-script&callback

【问题描述】：

有谁知道如何使用 V3 API 做到这一点？

本例使用 V2

http://gdata.youtube.com/feeds/api/videos/gzDS-Kfd5XQ?v=2&alt=json-in-script&callback=whatever

而且callcack是

<script type="text/javascript">function youtube' . $random . '(data)document.getElementById(\'title' . $code . '\').title = data.entry[ \'title\' ].$t.substr(0,100);</script>

【问题讨论】：

我认为，由于 v3 是原生 JSON 并且完全符合 CORS，您只需进行常规 ajax 调用，当数据返回时，使用它触发回调 ...换句话说，in 旨在消除对 JSONP 的需求。

你是怎么做到的？刚刚注意到我获取标题/描述等的方式现在只返回HTTPS://YOUTUBE.COM/DEVICESUPPORT。您是否必须获取 v3 的 API 密钥，或者是否还有像 gdata 这样的 URL 来获取视频数据？

【参考方案1】：

Vadim 解决方案不起作用（至少对我而言）。答案在这里https://developers.google.com/youtube/v3/sample_requests

例子：

https://www.googleapis.com/youtube/v3/videos?id=qzaBVoti3U0&key=[YOURAPIKEY]&part=snippet,contentDetails,statistics,status

将返回如下数据：
