在我的开发环境中，我有一个用户刚刚收到以下范围的OAuth令牌。
一切看起来都很好，我为用户存储了令牌。然后，我请求列出用户的日历，并且收到请求无效的invalid_grant。我用另一个用户的令牌尝试了相同的请求（也在我的开发环境中），它可以正常工作。
我最初只有第一个作用域设置，即写级别访问。这就是所有现有令牌的创建对象。在测试期间，我添加了其他范围。
我已尝试为我的项目中的Google API更新NuGet软件包。
这是我的班级正在打电话。

在您所描述的情况下，使用Google Developer OAuth Playground极大地帮助了我。默认情况下，您可以使用OAuthPlayground本身作为客户端来获得授权（并观看流量）。但是，诀窍是进入[设置]齿轮并选中[x]复选框。使用您自己的OAuth凭据并尝试授权您的客户端。 IMO，这是一个非常有用的调试工具，我想确保您了解它。
