When I send the POST request for the push notification on the web browser, it says that:

"Access to XMLHttpRequest at 'https://go.urbanairship.com/api/push' from origin has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."


Is there anyone who can resolved this problem?

Thank you.

Didn't find what you were looking for?
