Display google calendar events authenticating as service account - Golang App
问题
在我的Go应用程序中，目前在我的开发机器上作为本地主机运行（最终在Linode上运行），我希望能够简单地显示我自己Google账户中一个日历中的公共Google日历事件。目前，这只在控制台上显示，因为我想在原则上使其工作，并且我在应用程序的索引页面处理程序中有以下代码：
googleCalendar, err := calendar.NewService(r.Context(), option.WithCredentialsFile("./googleAuth.json"))
if err != nil {
app.errorLog.Println(w, err)
}
calEvents, err := googleCalendar.Events.List("primary").TimeMin(time.Now().Format(time.RFC3339)).MaxResults(5).Do()
if err != nil {
app.errorLog.Println(err)
}
if len(calEvents.Items) > 0 {
for _, i := range calEvents.Items {
fmt.Fprintln(w, i.Summary, " ", i.Start.DateTime)
}
} else {
app.errorLog.Println("No calendar events to display")
}
我认为唯一的方法是使用服务帐号，因为我不是G Workspace（GSuite）用户（该应用程序最终将在Linode上运行），直接使用Oauth2过于繁琐，并且在我的情况下可能不可用。我已经在我的Google Dev控制台中启用了Google日历API，并设置了一个服务帐号，创建/下载了一个JSON密钥文件（如代码中所示）。我已将服务帐号电子邮件添加为必要日历的共享用户。代码可以编译和运行，但是我只得到了"No calendar events to display"，因为'Items'为空（日历中确实有事件）。这里是否还需要做更多的工作？如何获取这些日历事件？谢谢。
英文:
Within my Go app, currently running as localhost on my dev machine (ultimately on a Linode), I wish to simply display public Google Calendar events from a calendar in my own Google account. At the moment this only displays to console because I want to get it working in principle and I have this code in the index page handler of my app.
googleCalendar, err := calendar.NewService(r.Context(), option.WithCredentialsFile("./googleAuth.json"))
if err != nil {
app.errorLog.Println(w, err)
}
calEvents, err := googleCalendar.Events.List("primary").TimeMin(time.Now().Format(time.RFC3339)).MaxResults(5).Do()
if err != nil {
app.errorLog.Println(err)
}
if len(calEvents.Items) > 0 {
for _, i := range calEvents.Items {
fmt.Fprintln(w, i.Summary, " ", i.Start.DateTime)
}
} else {
app.errorLog.Println("No calendar events to display")
}
The only way I think to do this is to use a service account because I am not a G Workspace (GSuite) user (the app will finally run on a Linode), Oauth2 directly is overkill and likely not available in my circumstances anyhow. I have enabled Google calendar API in my Google Dev Console and setup a service account, created / downloaded a json key file (as in the code). I have added the service account email as a shared user to the necessary calendar. The code compiles and runs but I only get my "No calendar events to display" because 'Items' is empty (the calendar does have events). Is there more here that needs to be done ? How to fetch these calendar event ? thanks

好的，以下是翻译好的内容：
嗯，我终于找到了解决这个问题的方法。我发布的代码在这种情况下是所需的全部内容，但是关键字"primary"的使用不起作用。我不知道为什么，根据Google的文档，它应该起作用。我只是用实际的日历ID（而不是日历名称）替换了"primary"，然后我的所有事件都显示出来了。😄
英文:
Well, I finally found a solution to this issue. The code I posted is all that's needed in this case BUT it's the use of the keyword "primary" which is not working. I do not know why, it should work according to the Google documentation. I simply substituted "primary" with the actual calendar ID (not the calendar name) and all my events displayed. 🙄
