Iframe 如何在非公共域页面上嵌入一些YouTube视频？

我目前正在写一个音频播放器，可以用热键播放和控制YouTube视频。然而，我有一个问题：由于某种原因，应该可以嵌入的视频会出现“不可用”错误

嵌入代码的一个示例：

<iframe width="560" height="315" src="https://www.youtube.com/embed/d6QE4EJrIFc" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

嗯，你的iframe在我的测试域上玩得很好。不知道为什么它对你不起作用。我看不到任何国家/地区的限制。@john10您的测试域是公开的吗？或者你（和我一样）只是创建一个简单的.html文件，然后在浏览器中打开？@john10我只是做了一些进一步的测试。。。当在“localhost”上托管文件时，它会工作，并且视频会播放。当我直接打开HTML文件时，它似乎不起作用…@ImJustACowLol我找不到源代码，但我确实记得几年前，对避免在.HTML文件上播放YouTube视频（甚至谷歌新闻API）进行了更改。也许会对你有所帮助。@Mauriciariasolave啊，我不知道那个网址。有太多的参数需要手工检查，但我会在晚上下班后写一个脚本来检查。我会随时通知你：）
