无法使用谷歌日历API

Question

这是使用此代码我试图用客房内设施与空间A.创建事件（资源使用谷歌日历API添加房间）事件创建成功，但是当我检查我的Java代码来阻止房Google日历并尝试查看可用空间。我希望它不应该显示或应该显示罢工可以任何人请告诉我这个解决方案在哪里做我错了是否有权限问题请建议我。

大家好从谷歌搜索长后，我找到解决方案。

步骤来创建事件谷歌事件。

第一步：设置以下范围授权API。

1. https://www.googleapis.com/auth/calendar.readonly
2. https://www.googleapis.com/auth/calendar

第二步：在授权请求许可管理和查看日历，使用具有允许它。 和哪些将生成授权码。

步骤3：由生成的授权代码

步骤4创建ACCESS_TOKEN：通产生的access_token到谷歌了解创建事件。

Java代码来创建谷歌事件

public static com.google.api.services.calendar.Calendar getCalendarService() { 

     GoogleCredential credential = new GoogleCredential().setAccessToken(access_token); 

     return new Calendar.Builder(HTTP_TRANSPORT, JSON_FACTORY, credential).build(); 

} 

这些步骤对我的工作块房间，而使用谷歌日历API创建活动。

我曾尝试使用服务帐户在这种情况下，我们能够创造活动，但无法阻止房的另一种方式。

您正在使用服务帐户。你需要记住的是一个服务帐户不是你。服务帐户拥有自己的Google日历帐户主要是其主日历。

String calendarId = "primary"; 
event = getCalendarService().events().insert(calendarId, event).execute(); 

这会将一个事件添加到服务帐户主Google日历，您无法在Web上直观地看到该日历。

你试过从你的代码做了events.list这应该告诉你的服务的事件占谷歌日历。

如果你希望能够看到这种视觉上，我建议你创建自己的个人谷歌日历帐户日历，并通过与服务共享它授予其服务帐户访问帐户的电子邮件地址。
