在Firestore API中进行分页 [英] Pagination in firestore api

问题描述

我正在尝试使用Firestore Beta对文档进行分页.我正在关注官方文档

I am trying to paginate documents with firestore beta. I am following the official docs

我看到有一个pageSize参数来说明要显示多少个文档，但是我看不到任何偏移量选项.有人知道我该怎么做分页系统吗?

I see there is a pageSize param to say how many documents you want to show, but i dont see any offset option. Does anybody know how can i do a pagination system?

谢谢

推荐答案

从您的文档链接中，我假设您正在使用REST API.在REST API中，可以指定一个pageToken参数.这可以从上一个请求返回的nextPageToken派生.

From your documentation link, I assume that you're using the REST API. In the REST API, there is a pageToken parameter, which you can specify. This can be derived from the nextPageToken returned from the previous request.

{
  "documents": [
    {
      object(Document)
    }
  ],
  "nextPageToken": ABCDEF1234567890,
}

下一个请求

 projects/my-project/databases/my-database/documents or projects/my-project/databases/my-database/documents/chatrooms?pageSize=20&pageToken=ABCDEF1234567890
