分页是您的最佳选择。因此，您可以向API调用传递一些查询参数，如限制和页数。例如，GET /users?limit=10&page=1 将获取前10个用户。如果您在后端使用Spring和数据库，Spring Data JPA已经内置了分页功能，使用起来相当容易。
英文:
Pagination is your best bet for this. So you could pass in some query params to the API call like limit and pageNumber. For example, GET /users?limit=10&page=1 will get you the first 10. If you are using Spring and a database on the backend. Spring Data JPA has pagination built in and it's fairly easy to use.

你可以使用分页来申请限制和页码。你可以像这样发起一个获取请求 => fetch(${url}/_limit=10&_page=1)，这将获取到你所需的输出。
英文:
You can use pagination to apply for the limit and page number.
You can make a fetch request like => fetch(${url}/_limit=10&_page=1)
and this will fetch you your desired output
