将事件插入 google 日历 nodejs

Question

我正在通读有关将事件插入 google 日历 api 的文档，但没有取得任何成功。我能够按照快速入门指南从我的 google 日历中提取事件列表，但现在我无法让插入工作。我保持环境设置不变，只是添加了插入方法，但我的错误是 There was an error contacting the Calendar service: Error: Insufficent Permission

Answer 1

我认为您的范围适合使用 calendar.events.insert()。那么这个修改怎么样呢？

我认为范围可能尚未反映到访问令牌。所以请删除 credentials.json 一次，然后再次授权范围。通过这个，它再次创建 credentials.json 。并且access token和refresh token反映了可以检索的范围。
在您的脚本中，console.log('Event created: %s', event.htmlLink) 的 event.htmlLink 变为 undefined。所以对于你的脚本，请修改为console.log('Event created: %s', event.data.htmlLink).

Answer 2

请包含范围 'https://www.googleapis.com/auth/calendar.event'。这是处理日历事件所必需的。
