I’m working on a react app. Where I’m requesting for an API by AXIOS. But When I run NPM START to test my app in localhost I’m getting CORS error. Here is the error Access to XMLHttpRequest at ‘https://********.com/trx_status.php’ from origin ‘http://localhost:3000‘ has been blocked by CORS policy: Request header field privatekey is not allowed by Access-Control-Allow-Headers in preflight response.
I’m new in react. Please tell me how can I solve this issue. Thank you…
The error is caused by the custom
privatekey header that is send to the server. This field has to be included in the
Access-Control-Allow-Headers response header from the server. It can be done using:
when using php the following snippet can be used:
header('Access-Control-Allow-Headers: X-Requested-With, privatekey');
