comparison of two json response bodies using gatling

Hi Team,
I am having two API requests and compare their response bodies ( returns in json) and print the difference if there is any difference identified along failing the request through gatling script.


.get(“API URL1”)
. check(bodyString.saveAs(“DR_Req1_ResponseBody”)))


.get(“API URL2”)

Please suggest how to get the difference of two response bodies and how to fail the requests if there is any difference identified.
I am using gatling 3.5.1 and maven plugin of version 3.1.1
