谷歌开放Calendar API，允许你添加Google Drive文件至Calendar事件

　　Google Calendar API允许你创建和修改Google Calendar上的事件。从今天开始，你可以使用API来添加Google Drive文件至Calendar事件，在你的App上实现，从而提高可用性和集成性。有了这个API你可以轻松地连接会议记录、添加预定好的PDFs至 事件。

这里是设置方法：

1. 从Google Drive获得文件信息（例子，通过Google Drive API）：

GET https://www.googleapis.com/drive/v2/files

{
 ...
 "items": [
  {
   "kind": "drive#file",
   "id": "9oNKwQI7dkW-xHJ3eRvTO6Cp92obxs1kJsZLFRGFMz9Q,
   ...
   "alternateLink": "https://docs.google.com/presentation/d/9oNKwQI7dkW-xHJ3eRvTO6Cp92obxs1kJsZLFRGFMz9Q/edit?usp=drivesdk",
   "title": "Workout plan",
   "mimeType": "application/vnd.google-apps.presentation",
   ...
  },
  ...
 ]
}

1. 使用Calendar API进行操作，实现此信息传送至事件：

POST https://www.googleapis.com/calendar/v3/calendars/primary/events?supportsAttachments=true

{
  "summary": "Workout",
  "start": { ... },
  "end": { ... },
  ...
  "attachments": [
   {
      "fileUrl": "https://docs.google.com/presentation/d/9oNKwQI7dkW-xHJ3eRvTO6Cp92obxs1kJsZLFRGFMz9Q/edit?usp=drivesdk",
      "title": "Workout plan",
      "mimeType": "application/vnd.google-apps.presentation"
   },
   ...
  ]
}

看！你不需要做什么特别的操作就可实现啦，下一步：

GET https://www.googleapis.com/calendar/v3/calendars/primary/events/ja58khmqndmulcongdge9uekm7

{
 "kind": "calendar#event",
 "id": "ja58khmqndmulcongdge9uekm7",
 "summary": "Workout",
 ...
 "attachments": [
  {
   "fileUrl": "https://docs.google.com/presentation/d/9oNKwQI7dkW-xHJ3eRvTO6Cp92obxs1kJsZLFRGFMz9Q/edit?usp=drivesdk",
   "title": "Workout plan",
   "mimeType": "application/vnd.google-apps.presentation",
   "iconLink": "https://ssl.gstatic.com/docs/doclist/images/icon_11_presentation_list.png"
  },
  ...
 ]
}
