Google表格Java API v4 BatchUpdate

Question

以下代码实际上只是Google表格Java API v4 QuickStart代码示例，但是我从另一篇文章中复制的BatchUpdate代码尝试了它; 运行代码会产生一个异常，引用包含文本的JSON对象：

“message”：“请求的身份验证范围不足。”，“原因”：“禁止”

当代码访问电子表格获取数据没有问题我不明白它是如何错过权限，虽然我从使用P12键而不是client_secrets.json文件复制它的代码。

任何指针将不胜感激。 谢谢。

请尝试添加应用程序所需的范围信息。

如方法：spreadsheets.batchUpdate中所述，需要以下OAuth范围之一：

• https://www.googleapis.com/auth/drive
• https://www.googleapis.com/auth/spreadsheets

Google表格API的可用OAuth 2.0范围信息列在使用OAuth 2.0授权请求中，除此之外，此SO帖子中给出的解决方案 - Google电子表格api请求的认证范围不足也可能有所帮助。
