pub.mime:mergeHeaderAndBody

You can use this service to reassemble the message into its original form so that it can be used as input to the pub.mime:createMimeData service (or any other service that requires the entire http response as an InputStream).

headerLines	Document IData object containing the message headers returned by pub.client:http. (The message headers are returned in the lines document inside the header output parameter that is produced by pub.client:http.)
body	Document IData object containing the body of the message returned by pub.client:http. This document must contain the body of the message in one of the following keys:
	Key	Description
	bytes	byte[ ] Optional. Body of the message (if pub.client:http returned the body as a byte[ ]).
	stream	java.io.InputStream Optional. The body of the message (if pub.client:http returned the body as an InputStream).
