问题 I'm having issue getting my ionic app to POST to my API. On my api I have set the following headers: header("Access-Control-Allow-Origin: *"); header("Access-Control-Allow-Headers: Content-Type"); header("Access-Control-Allow-Methods: GET,PUT,POST,DELETE,OPTIONS"); When posting from Postman or the actual website, everything functions as expected and I see these headers come back but once I open up my app and send a request, it no longer works.
