.net-core - 如何修复错误：“Google.Apis.Auth：应为 YouTubeAPI 设置至少一个客户端机密（已安装或 Web）”

问题描述

我创建了一个 HTTP 触发 azure 函数，它包含自动将视频上传到 YouTube 的代码（如下）。来源：（https://developers.google.com/youtube/v3/docs/videos/insert）。

当我尝试使用 Visual Studio 在本地运行应用程序时，出现以下错误：

执行“Function1”（失败，Id=d601d64a-2f2c-4f8a-8053-a2f33ca21dbc）System.Private.CoreLib：执行函数时出现异常：Function1。Google.Apis.Auth：应设置至少一个客户端机密（已安装或 Web）

它看起来像一个 Google 身份验证错误，但我不确定如何解决这个问题，而且我看到 YouTube API 不支持服务帐户？这个问题怎么解决，有办法解决吗？提前致谢。

解决方案

看起来您正在尝试使用服务帐户来执行 OAuth2 Web 服务器流程，但这是行不通的。创建服务帐户凭据的正确代码形式如下。

GoogleCredential credential;
using (var stream = new FileStream(serviceAccountCredentialFilePath, FileMode.Open, FileAccess.Read))
              {
                    credential = GoogleCredential.FromStream(stream)
                         .CreateScoped(scopes);
                }

笔记

正如我在您的其他问题中提到的那样，YouTube API 不支持服务帐户身份验证。您必须使用 Oauth2，我不相信这可以在 azure 函数中完成。由于无法生成 Web 浏览器窗口来请求用户授权。
