好的，经过数周的 API、.NET 和 JavaScript 文档研究后，我构建了以下解决方案....
按照YouTube V3 Developer documentation 设置您的所有密钥。 （选择 OAuth、Web 应用程序，并为您的 Javascript 和重定向代码输入 URI）
接下来使用OAuth Playground 获取您的刷新代码
一旦你有了你的 client_id、client_secret 和 refresh_token，你就准备好了！
此代码通过后面的代码进行简单的 HTTP/REST 调用，以获取有效期为 3600 秒（默认值）的 access_token。然后它将此字符串传递给 JavaScript 代码以供使用 ****WARNING****
这个不使用任何 .NET 或 JavaScript 库，除了一个文件 cors_upload.js available on GitHub
唉，代码

结果...从受密码保护的网页中，我可以让用户将视频上传到我的频道，不公开，并存储视频 ID，以便以后将该视频嵌入我的网站。
