rest_ensure_response( WP_Error|WP_HTTP_Response|mixed $response )

Ensures a REST response is a response object (for consistency).


Description

This implements WP_HTTP_Response, allowing usage of set_status/header/etc without needing to double-check the object. Will also allow WP_Error to indicate error responses, so users should immediately check for this value.


Parameters

$response

(Required) Response to check.


Return

(WP_REST_Response|mixed) If response generated an error, WP_Error, if response is already an instance, WP_HTTP_Response, otherwise returns a new WP_REST_Response instance.
