How to create expiring URL links to Amazon S3 with ASP net

Question

I am exploring C# libraries like lits3 in my project. I want to know is if there is a way to create a signed URL which has expiration using ASP.net. I couldn't find any on researching? Any help here will be great.

Answer 1

Yes, there is a solution. Well, using the Amazon .net SDK you can get preSignedUrl.

using (AmazonS3 client = Amazon.AWSClientFactory.CreateAmazonS3Client("your access key ID", "you secret key")) 

{ 

                        GetPreSignedUrlRequest getPreSignedUrl = new GetPreSignedUrlRequest().WithBucketName(bucketName);                                    getPreSignedUrl.Key = key:

                        getPreSignedUrl.Expires = DateTime.Now.AddSeconds(60);

}
