【问题描述】：
在我的 java 后端应用程序中，我想每周使用石英作业将我的 youtube 视频状态从公开更改为私人，这是一个预定的作业。所以我使用 YouTube Data API (v3) 的 Videos Update 来完成这项工作。
请参阅YouTube Data API Reference Videos: update 和代码示例Resource>videos,Method>update。 根据Obtaining authorization credentials，获取授权凭证有两种方式，一种是OAuth 2.0，另一种是使用API Keys。我选择使用API Keys 因为它比 oauth2 更简单。
我已经从 Google API 控制台检索了 API 密钥，我运行从 youtube 的文档 Resource>videos,Method>update 复制的代码示例并运行它们，它们都出现 401 错误。
{
"error": {
"code": 401,
"message": "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"errors": [
{
"message": "Login Required.",
"domain": "global",
"reason": "required",
"location": "Authorization",
"locationType": "header"
}
],
"status": "UNAUTHENTICATED"
}
}
我不知道为什么我不能通过使用 API 密钥调用 videos.update 来工作。我不想使用 OAuth2，我认为使用 API Keys 是更好的方法。因为，不可能打开浏览器窗口并让用户在石英工作中进行 oauth 登录和授权，谁能告诉我什么是有问题怎么办？
代码示例如下
