如何对 Aws s3 列表 object 进行分页？

Question

I have over 20000 images in s3 and I want to paginate the first 100 after clicking on pagination 2nd link it should load the second 100 images and so on.

const params = { Bucket: "test-bucket", Delimiter: '/', MaxKeys: 100, Prefix: "thumbnail_images/Q" };

async function* listAllKeys(params) {
  try {
    do {
      const data = await s3.listObjectsV2(params).promise();
      params.ContinuationToken = data.NextContinuationToken;
      yield data;
    } while (params.ContinuationToken);
  } catch (err) {
    return err;
  }
};

I am using aws-sdk node package.

s3 doesn't provide any pagination feature but you can develop your own.

use s3 get object list to get a list of all images and store it in var imageList. on first request from UI pass(page:0) the images from imageList[100 0:(100 0)+100] on second request from UI pass(page:1) the images from imageList[100 1:(100 1)+100] and so on.
