使用 YouTube 数据 API (v3) 通过 API 键更新视频出现 401 错误

Question

在我的 java 后端应用程序中，我想每周使用 quartz 作业将我的 YouTube 视频状态从 public 更改为私有，这是一项预定的工作。所以我使用 YouTube 数据 API (v3) 的 Videos Update 来完成这项工作。

参见 YouTube 数据API 参考视频：更新和代码示例Resource>videos,Method>update。根据Obtaining authorization credentials，有两种获取授权凭据的方法，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 和 [=61] 复制了代码示例=] 他们，他们都得到了 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"
  }
}

我不明白为什么我不能使用 API 键来调用 videos.update。我不想使用 OAuth2，我认为使用 API 密钥更好 way.Because，无法打开浏览器 window 并让用户在quartz 工作，谁能告诉我问题是什么以及如何解决？

代码示例如下

Answer 1

根据您自己引用的 the official doc，要调用 Videos.update API 端点，您需要获得适当的授权：

Authorization

This request requires authorization with at least one of the following scopes (read more about authentication and authorization).

Scope

https://www.googleapis.com/auth/youtubepartner
https://www.googleapis.com/auth/youtube
https://www.googleapis.com/auth/youtube.force-ssl

因此，您无法避免在您的应用程序中使用 OAuth 2.0 authentication/authorization 流程。请注意，API 键用于 只读 public 数据。

对于您问题中的部分：

[...] it is impossible to open a browser window and make the user to do a oauth login and authorization in a quartz job [...]

API 有解决方案。请阅读以下两个文档：OAuth 2.0 for Mobile & Desktop Apps and Using OAuth 2.0 for Web Server Applications.
