谷歌日历返回无效授权

Question

我有一个客户试图从我们的 Web 应用程序访问他们的日历。一切都适用于我们所有的其他客户，所以我不确定这里有什么不同，除了这个客户在澳大利亚并且使用非 gmail.com 电子邮件地址。

客户能够授权我们的应用程序，我们确实为用户获得了一个 oauth 令牌。我们请求访问日历并且客户授予了它。当我们请求所有日历的列表时，我们会收到无效的授权消息。

下面是我们用来访问他们日历的代码。被调用的方法是 GetAllWritableCalendars。

后来我用不同的方式问了这个问题。也许这更相关一些。也许还有更多可用信息。不管情况如何，我发现了如何正确测试事物。
