Google+ Moments.insert - 未经授权的错误

根据 Moments 的文档，使用 Google+ API 插入具有以下范围的自编是必需

https://www.googleapis.com/auth/plus.login

我正在使用所有可能的 PlusService 范围进行身份验证，但仍然收到以下错误

Google.Apis.Requests.RequestError Unauthorized [401] errors [ 消息[未授权] 位置[ - ] 原因[未授权] 域[全球]

我已经测试了身份验证，它正在工作，我能够列出活动和其他内容。 它唯一的插入时刻给了我这个错误。 我也尝试在PHP中执行此操作，但遇到了相同的错误。 我错过了什么？

更新：我在文档中发现了一些东西。

对时刻进行验证时，必须包括 数据请求可见操作参数，用于指定应用的类型 应用程序将写入的活动。

我还没有弄清楚如何设置这个数据请求可见操作。
