When calling rest api from client running on different port, facing following issue

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost' is therefore not allowed access. The response had HTTP status code 400.

Server: http://localhost:8080
Client: http://localhost:80

Checked response headers in Postman, No "access-control-allow-headers" present in response

How to add these headers in Om2m source code?

Thanks
Regards
Kamran
