In my layout. I render the script.
@Scripts.Render("https://maps.googleapis.com/maps/api/js?key=AIzaSyAPKeBYFqGsbfGiH7wvx1mMH9A4I")
But the console will give me a warning:
Google Maps API warning: NoApiKeys https://developers.google.com/maps/documentation/javascript/error-messages#no-api-keys
How to solve this problem.
