如何在使用服务帐户时在我的YouTube / Google帐户下上传视频文件

我希望创建一个服务器应用程序来检查所述服务器上的文件夹,并自动上传已放入所述文件夹的所有视频文件。服务器是远程的,不会发生人为干预。

在阅读Youtube的API v3指南后,我得出结论,我需要一个“服务帐户”才能上传这些视频,因为应用程序会不断监视此文件夹。我的问题是:是否可以使用服务帐户上传视频,然后将视频放在我的个人YouTube帐户下?

如果这实际上是可能的;我创建了以下代码,但遇到401 Unauthorized(Invalid Token)错误。

我有以下可编辑的来源;我试图让它尽可能小:

最后,我读了很多关于服务帐户的故事。有人说他们与Youtube兼容,其他人说他们不是。这让我感到困惑,我发现了更多关于stackoverflow的问题,这些问题并不是确定无论是否可能。

答案 0 :(得分:0)

YouTube不支持服务帐户,他们也没有计划:

然后,一个选项是设置您的应用程序以执行初始oAuth流程(您通过一次用户交互启动),然后作为该流程的一部分,您将同时发布临时访问令牌和刷新令牌。刷新令牌可用于获取更多访问令牌,而无需再次运行oAuth流,并且刷新令牌不会自行过期(但可以手动撤销)。因此,您的应用可以存储您的刷新令牌,监控您的文件夹,然后在需要上传新视频时自行获取访问令牌。看到这个链接:

(请注意,它特别提到了守护程序的想法,该守护程序监视目录以便上传新视频)。
