【中文标题】有没有办法获取给定数据库的列表长度?【英文标题】:Is there a way to get the list length for a given database? 【发布时间】:2021-08-08 00:22:34 【问题描述】:我可以使用https://api.notion.com/v1/databases/:id/query 获取给定数据库的分页子列表。但是我可以在任何地方获取当前的孩子数量吗?
【问题讨论】:
【参考方案1】:该 API 在当前版本的 API(Notion-Version:2021-05-13)中没有提供结果计数。
【讨论】:
【参考方案2】:如果你想要数据库中的页数(子),假设是javascript。
<!DOCTYPE html>
<html>
<body>
<p>Click the button to create an array, then display its length.</p>
<button onclick="myFunction()">Find Length</button>
<p id="demo"></p>
<script>
function myFunction()

【讨论】:
这样我必须请求所有内容,然后在我的后端/前端中检查它。 API 在响应中发送的最大结果数为每页 100 个。对于大型数据库,我必须发出多个请求才能检查列表的长度。这似乎非常低效。 不幸的是,Notion 无法轻松返回数据库中的全部项目。以上是关于有没有办法获取给定数据库的列表长度?的主要内容,如果未能解决你的问题,请参考以下文章
