使用YouTube API将视频上传到多个频道

Question

使用YouTube API将视频上传到单个频道非常简单。 这是我如何使用PHP客户端库目前做,,

脚本运行的第一次，促使我与一个窗口来验证请求，令牌被授予并在60分钟内到期。

我想使用相同的脚本将视频上传到我拥有的不同频道。例如，如果我有3个不同的频道，我可以登录到不同的浏览器来验证应用程序。 我目前有超过10个YouTube频道，每隔几个小时后我想上传内容。

有没有一种方法可以从中央服务管理所有这些通道，以避免每次添加新通道时进行身份验证。或者有没有一种方法可以使用我的YouTube用户登录信息来验证YouTube的API？ 任何建议将不胜感激。谢谢。

YouTube API与其他Google API略有不同。通常，认证是基于用户帐户的。因此，如果我通过身份验证来访问我的Google日历，则可以访问我所有的Google日历。

YouTube API是基于用户频道的。您将不得不为每个频道验证一次应用程序。然后确保你有一个刷新令牌。将刷新令牌存储在与通道名称关联的位置。然后，您的自动脚本将能够使用刷新令牌请求新的访问令牌，并在需要时访问您的帐户。
