在 aws-sdk-go-v2 for Go 中为 AWS s3 添加 Presign URL Expiration

Question

There is a very fine example of using the aws-sdk-go-v2 to create pre-signed URLs.

This works well but I'm stuck on setting the expiration time. I do see the PresignOptions struct has an Expires but I'm not certain how to do that.

I also see WithPresignExpires but alas, I also do not know how to use this given the example.

Can an example be provided here? I'm learning Go but something is just outside my grasp here.

Answer 1

Seems I can do this for 60 minute expiration.

func GetPresignedURL(c context.Context, api S3PresignGetObjectAPI, input *s3.GetObjectInput) (*v4.PresignedHTTPRequest, error) {
    return api.PresignGetObject(c, input, s3.WithPresignExpires(3600*time.Second))
}
