Emberjs 2 remove CORS and CSP

I'm trying EmberJs 2 and found a problem making Ajax requests. I have read a lot of questions on stackOverflow and still can't resolve the problem. I access the emberapp from http://localhost:4200 and my API server(PHP) is in http://localhost. Below is a screen shoot of the console.

What should I do step by step? Can you help me please?

Thanks in advance.
