WordPress JSON API - Request Header Error

Question

I'm working with the WordPress JSON API plugin to make requests to get posts and etc from my blog.

When I try to access a simple url from browser it works perfectly, but when I try to access from my Ionic application this following erros occurs:

Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.

Do I need to do something from my WP blog to allow it?

i found out this answer, it should be helpful Enable CORS on JSON API Wordpress — Stefano Saitta

It is most likely due to a cross-origin request. So try adding the below headers in your functions.php file.

function add_cors_http_header(){
    header("Access-Control-Allow-Origin: *");
    header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");

}
add_action('init','add_cors_http_header');

Make sure that you haven't already used header in another file, or you will get a nasty error.

Hope it helps you.
