WP_REST_REQUEST: how to add "_embed" to request parameters - wordpress

Question

I added this function to my wordpress REST API to have a custom endpoint
function getSettimanaEventi(){
$request = new WP_REST_Request( 'GET', '/wp/v2/tribe_events' );
$request['_embed'] = '1';
$request['filter[meta_query][0][key]'] = '_EventStartDate';
$request['filter[meta_query][0][value][0]'] = '2017-07-03 00:00:00';
$request['filter[meta_query][0][value][1]'] = '2017-07-09 00:00:00';
$request['filter[meta_query][0][compare]'] = 'BETWEEN';
$request['filter[meta_query][0][type]'] = 'DATE';
$response = rest_do_request( $request );
return $response;
i got a response but there isn't the embedded content.
I know the parameters with a leading '_' are private but i need embedded content.
How can i do?

Answer 1

This works for me perfectly
global $wp_rest_server;
$request = new WP_Rest_Request('GET', '/wp/v2/posts');
$response = rest_do_request($request);
$response = $wp_rest_server->response_to_data($response, true);

The only way i found is to add the "_embed" parameter to the url (when you call it from Postman for example) and delete it from the request parameters

(Update - this doesn't seem to be working. I'll update if I figure it out.)
You must set it in the super global like this:
function getSettimanaEventi () {
// Set super global to simulate request param
$_GET['_embed'] = 1;
$request = new WP_REST_Request( 'GET', '/wp/v2/tribe_events' );
$request['filter[meta_query][0][key]'] = '_EventStartDate';
$request['filter[meta_query][0][value][0]'] = '2017-07-03 00:00:00';
$request['filter[meta_query][0][value][1]'] = '2017-07-09 00:00:00';
$request['filter[meta_query][0][compare]'] = 'BETWEEN';
$request['filter[meta_query][0][type]'] = 'DATE';
$response = rest_do_request( $request );
// cleanup after
unset($_GET['_embed']);
return $response;
}
