I'm making a file manager and using the api provided by aws s3, but the response here is the cursor paging function, it's pretty bad that Fb clearly returns the next key and the back key here. then only provide key next and I had to handle key back manually....
And the problem is that as far as I know large data pages like AMZ or Fb will use cursor pagination. So is there any way for me to calculate the total number of pages to display the buttons 1 2 3... like this?
Hope I will get help from those who have had the same problem as me, thanks

Cursor-based pagination is a technique for paginating large datasets where the server provides a "cursor" to the client, which can be used to retrieve the next or previous page of results. This is often used when the dataset is too large to be returned in a single response, or when the dataset is continually changing and the server wants to provide a stable reference point for the client to paginate through the data.
To calculate the total number of pages when using cursor-based pagination, you will need to make multiple requests to the server to retrieve the data. Each request will return a limited number of results, as well as a cursor that can be used to retrieve the next or previous page of results.
Here is an example of how you might implement cursor-based pagination in your file manager:
Make an initial request to the server to retrieve the first page of results.
Parse the response from the server and retrieve the cursor for the next page of results.
Make additional requests to the server using the cursor for the next page of results until all pages have been retrieved.
As you retrieve each page of results, keep track of the total number of pages and the current page number.
Use this information to display buttons or a pagination interface to allow the user to navigate through the pages of results.
It's worth noting that some APIs may provide additional information in the response that can be used to calculate the total number of pages, such as the total number of results or the size of each page. In these cases, you can use this information to more accurately calculate the total number of pages and display a pagination interface to the user.
