我们正忙于在 rasp pi 上使用 Google Calendar API 检索 Google 日历的应用程序。我们用 C# 编写并在 Windows 上进行了测试，我工作得很好。当我们在 Rasp PI (xbuild) 上编译它时，我们没有收到任何错误，但是当我们运行 (mono) 它时，我们会收到以下错误：

Unhandled Exception: Google.GData.Client.GDataRequestException: Execution of request failed: http://www.google.com/calendar/feeds/USERNAME@gmail.com/private/full?start-min=2013-10-29T14:11:41Z ---> System.Net.WebException: The remote server returned an error: (401) Authorization required.

有人可以帮助我们，我们没有看到解决方案。

我们通过运行以下代码解决了身份验证问题：

mozroots --import --ask-remove

这是因为 Mono（默认情况下）不允许外部连接，因此您已将其添加到证书列表中。
