在对Google表单进行多次调用时，API身份validation不适用于第二次调用：请求的身份validation范围不足

所以基本上我在这里所做的是我为我自己的目的劫持了Google表格api node.js快速入门指南。 一切都在这里工作，直到它碰到我的spreadsheets.batchUpdate，然后一切都变得古怪。

如果我注释掉spreadsheets.batchUpdate中的“auth”初始化，我会收到错误消息： The API returned an error: Error: The request does not have valid authentication credentials.

如果我注释掉spreadsheets.batchUpdate中的“auth”初始化，我得到错误消息： The API returned an error: Error: Request had insufficient authentication scopes.

所有我想要做的这些调用是从表中获取一些数据，然后删除行后，但我无法弄清楚这个身份validation问题。

https://www.googleapis.com/auth/spreadsheets.readonly会为您提供阅读权限。 您需要使用https://www.googleapis.com/auth/spreadsheets范围更新工作表。

https://www.googleapis.com/auth/spreadsheets.readonly

 Allows read-only access to the user's sheets and their properties. 

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

 Allows read/write access to the user's sheets and their properties.
