Question

我们正在尝试将通过Raspberry Pi上的串行连接接收的传感器数据上传到Google电子表格。我们发现了各种不同的OAuth2身份验证教程，可以从python脚本访问Google电子表格。但是，我们无法通过一条错误消息告诉我们，我们在验证过程中遇到了一个关键错误。

这是我们目前的代码:(这是一个空的测试谷歌帐户）

非常感谢任何帮助。

您可以测试下一个代码：

from oauth2client.service_account import ServiceAccountCredentials

scopes = ['https://www.googleapis.com/auth/sqlservice.admin']

credentials = ServiceAccountCredentials.from_json_keyfile_name(
'/path/to/keyfile.json', scopes=scopes)
