我从这里。

采样工作正常，但身份验证问题是存在的。

sample works fine but authentication issue is there

com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
"code": 403,
"errors": [
 {
   "domain": "usageLimits",
   "message": "Access Not Configured",
   "reason": "accessNotConfigured"
 }
],
"message": "Access Not Configured"
}

我还启用了日历API

I have also enabled calendar API

我缺少任何配置??

帮助！谢谢你。
