how to make a request to GCM to send a notificatio

问题:

actually i want to make a request to GCM to send a notification through XHR I already make request to GCM using the cURL utility but i don't know how to do it with XHR. Is there any way to do that

Good news! There's a dedicated page as well as a demo of your inquiry in the documentation!

You can not. At least, not directly because GCM API does not include CORS headers so it is not intended to be used from the browser. You need to send a signal to your own server and replicate the cURL command as the answer of that signal. See my other response: How to send push notifications in Chrome(Progressive Web Apps)
