How to sign using signature v4 for aws s3

[teammakdi]

Hi,

I'm using @aws-sdk/s3-request-presigner to create a presigned url

Example

const { S3Client, GetObjectCommand } = require('@aws-sdk/client-s3')
const { Upload } = require('@aws-sdk/lib-storage')
const { getSignedUrl } = require('@aws-sdk/s3-request-presigner')

const s3Client = new S3Client({
  forcePathStyle: true,
  region: 'us-east-1'
})

async function uploadImage (imageId, buffer) {
  const params = {
    Bucket: 'test',
    Key: `images/${imageId}`,
    Body: buffer,
    ContentType: 'image/png'
  }
  const upload = new Upload({
    client: s3Client,
    params
  })
  await upload.done()
}

async function getImageSignedUrl (imageId) {
  const command = new GetObjectCommand({
    Bucket: 'test',
    Key: `images/${imageId}`
  })
  return await getSignedUrl(s3Client, command, {
    expiresIn: 604800
  })
}

Issue is the link gets expired early, within 6-8 hours.

Have gone through https://repost.aws/knowledge-center/presigned-url-s3-bucket-expiration, hence wanted to try out v4 signature.
