About matlab production server config, I am quite sure that I have add --cors-allowed-origins * in the server config file, but the browser still show me: XMLHttpRequest cannot load http://localhost:9910/BondTools/pricecalc. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. Anyone could be helpful? Thanks in advance

save the file in html, open the file with Internet exploler. that is how it works for me, modern browser requires a complex security headers.

Hi,
In my opinion this is because you are accessing the API from a file. You will need to apply different solutions to different browsers, the below link will help you to get a deep understanding.
Thanks,
