GOAL
Upload objects to S3 with encryption (AES256/KMS) using the created presigned URL.Steps
2. Deploy the Mule application and trigger it to retrieve the presigned URL.
Sample response for presigned URL:
https://ah-bucket-1.s3.ap-southeast-2.amazonaws.com/ah-bucket-test-2?X-Amz-Security-Token=...
3. To upload with no encryption, send a PUT request to the presigned URL.
> curl -L -X PUT <presigned_url> \ --data 'payload'When using encryption, additional headers are required.
For AES256:
curl -L -X PUT <presigned_url> \ -H "x-amz-server-side-encryption: AES256" \ --data 'payload'For KMS:
curl -L -X PUT <presigned_url> \ -H "x-amz-server-side-encryption: aws:kms" \ --data 'payload'
