rest_allowed_cors_headers filter-hook . WP 5.5.0
Filters the list of request headers that are allowed for REST API CORS requests.
The allowed headers are passed to the browser to specify which headers can be passed to the REST API. By default, we allow the Content-* headers needed to upload files to the media endpoints. As well as the Authorization and Nonce headers for allowing authentication.
Usage
add_filter( 'rest_allowed_cors_headers', 'filter_function_name_6025' );
function filter_function_name_6025( $allow_headers ){
// filter...
return $allow_headers;
}
- $allow_headers(string[])
- The list of request headers to allow.
