我有一堆密钥：客户端 ID、客户端密码、API 密钥
但是所有文档都显示了使用人工交互的身份验证。
如何在没有用户交互的情况下使用点网库与 Google API v3 和 AnalyticsService 进行交互？如果我只使用 API 密钥，我会得到“需要 Google.Apis.Requests.RequestError 登录”
我在任何地方都找不到这样做的样本。
编辑：这是一个谷歌分析帐户，我可以完全访问它，用户名，密码，客户端 ID，客户端密码，api/开发者密钥，一切。我只想让实用程序每天在没有我的情况下下载数据。
这是我的工作代码，这是我通过批处理文件进程调用的控制台应用程序。我不是 .Net 开发人员，所以这段代码可能并不完美，如果您看到任何需要改进的地方，请告诉我！错误处理是最小的，因为我不希望一次失败杀死批次
我正在使用注册表来存储访问令牌和过期时间在应用程序文件夹中还有 privatekey.p12 文件该帐户是用户而不是配置文件上的管理员。
