com.amazonaws.services.s3.model.GeneratePresignedUrlRequest

All Implemented Interfaces:

ReadLimitInfo, SSECustomerKeyProvider, Serializable, Cloneable

public class GeneratePresignedUrlRequest
extends AmazonWebServiceRequest
implements SSECustomerKeyProvider, Serializable

Contains options to generate a pre-signed URL for an Amazon S3 resource.

Pre-signed URLs allow clients to form a URL for an Amazon S3 resource and sign it with the current AWS security credentials. A pre-signed URL may be passed around for other users to access the resource without providing them access to an account's AWS security credentials.

Parameters:

bucketName - The name of the bucket containing the desired Amazon S3 object.

key - The key under which the desired Amazon S3 object is stored.

GeneratePresignedUrlRequest

public GeneratePresignedUrlRequest(String bucketName,

                                   HttpMethod method)

Creates a new request for generating a pre-signed URL that can be used as part of an HTTP request to access the specified Amazon S3 resource.

When specifying an HTTP method, you must send the pre-signed URL with the same HTTP method in order to successfully use the pre-signed URL.

Parameters:

bucketName - The name of the Amazon S3 bucket involved in the operation.
