node.js - 将事件插入谷歌日历nodejs

Question

我正在阅读有关将事件插入谷歌日历 API 的文档，但没有取得任何成功。我能够按照快速入门指南并从我的谷歌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，但我的错误是联系日历服务时出错:错误:权限不足

Answer 1

我认为您的范围对于使用calendar.events.insert()是正确的。那么这个修改怎么样？

1. 我认为范围可能尚未反射(reflect)到访问 token 中。因此，请删除 credentials.json 一次，然后再次授权范围。这样，它会再次创建credentials.json。并且可以检索反射(reflect)范围的访问 token 和刷新 token 。
2. 在您的脚本中，console.log('Event created: %s', event.htmlLink) 的 event.htmlLink 变为 undefined 。因此，对于您的脚本，请修改为 console.log('Event created: %s', event.data.htmlLink)。
