Cors Header Missing ?

[csselo]

rest.php:1 Access to XMLHttpRequest at 'http://localhost:4000/jsonrpc' from origin 'http://localhost' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Altough I add header

?

Hi @csselo

Could you please post your server code? I'm wondering why it says "rest.php", are you using php?

json-rpc is transport agnostic library, it does not deal with server interaction and hence does not have CORS handling. The latter should be implemented on your own.
