我只在最近一小时内尝试了17-20个请求并不认为我已经使用了所有的配额。我已经检查过我的项目中启用了GDrive api。请帮忙。
解决方案
基于此文档，错误403意味着您已达到Google Drive API的最高请求率。限制根据请求的种类而有所不同。建议的操作是批量处理。尝试减少客户端的HTTP连接数。
另一个解决方法是在开发者控制台中检查Google+ API的状态。它应该设置为 ON 。打开后等待几分钟，并确保您获得新的令牌。

I have only tried 17-20 requests in the last hour and don't think I have used all my quotas. I have checked that the GDrive api is enabled in my project. Please help.
解决方案
Based from this documentation, error 403 means that you have reached Google Drive API's maximum request rate. The limit varies depending on the kind of requests. The suggested action is to Batch the requests. Try to reduce the number of HTTP connections your client has to make.
Another workaround is to check the status for Google+ API in developer console. It should be set to ON. Wait for a few minutes after turning on, and ensure that you get a fresh token.
