Problems with push notification

[zonar...@gmail.com]

Good morning, I'm starting with an android application and I use a web page in php and js, I try to send a push notification and it gives me the following error.

"XMLHttpRequest can not load https://fcm.googleapis.com/fcm/send. Response to preflight request does not pass access control check: In 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http: // localhost' is therefore not allowed access."

Check in other forums and see the proposed solutions on modifying the .httacces or lines in php.

I leave the lines of code.

// API access key from Google API's Console

Define ('API_ACCESS_KEY', 'key');

$ RegistrationIds = array ('tonken');

// prep the bundle

$ Msg = array

(

'Message' => 'here is a message. Message '

'Title' => 'This is a title. Title ',

'Subtitle' => 'This is a subtitle. Subtitle ',

'TickerText' => 'Ticker text here ... Ticker text here ...'

'Vibrate' => 1,

'Sound' => 1,

'LargeIcon' => 'large_icon',

'SmallIcon' => 'small_icon'

);

$ Fields = array

(

'Registration_ids' => $ registrationIds,

'Data' => $ msg

);

$ Headers = array

(

'Authorization: key ='. API_ACCESS_KEY,

'Content-Type: application / json'

'Access-Control-Allow-Origin: *'

);

$ Ch = curl_init ();

Curl_setopt ($ ch, CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send');

Curl_setopt ($ ch, CURLOPT_POST, true);

Curl_setopt ($ ch, CURLOPT_HTTPHEADER, $ headers);

Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true);

Curl_setopt ($ ch, CURLOPT_SSL_VERIFYPEER, false);

Curl_setopt ($ ch, CURLOPT_POSTFIELDS, json_encode ($ fields));

$ Result = curl_exec ($ ch);

Curl_close ($ ch);

Echo $ result;

You could send me an example because everything I did did not work.

From already thank you very much.
