Google Android Messaging Cloud

Question

I am trying to send a message from my server to google cloud server, but I have a problem with it ... i get the server key (key for server applications), install it in this code:

$headers = array( 'Authorization: key=' .My server key, 'Content-Type: application/json' ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt ($ch, CURLOPT_SSL_VERIFYHOST, 0); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); $result = curl_exec($ch); 

after sending the message I have this result:

Unauthorized Error 401

I use this ip: 78.47.150.20

but when I use test ip 0.0.0.0/0, I have no problem.

 function sendNotification($registrationIdsArray, $messageData) { $apiKey = "YOUR_API_KEY"; $headers = array("Content-Type:" . "application/json", "Authorization:" . "key=" . $apiKey); $data = array( 'data' => $messageData, 'registration_ids' => $registrationIdsArray ); $ch = curl_init(); curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers ); curl_setopt( $ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send" ); curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 0 ); curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, 0 ); curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true ); curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode($data) ); $response = curl_exec($ch); curl_close($ch); return $response; }
