Bắt đầu với mẫu GeneratePreSignedUrl được hiển thị trong issue và tái hiện URL được tạo cho S3 bucket đã nêu. Kiểm tra hành vi của AWS SDK for Java đối với presigned request và cơ chế ủy quyền, sau đó xác minh rằng mẫu tạo ra một URL được S3 chấp nhận bằng cơ chế ủy quyền bắt buộc. Được xem là hoàn tất khi lỗi được báo cáo không còn xảy ra hoặc mẫu ghi rõ cấu hình được hỗ trợ.
