How to send a gcm message in php without using cURL? - php

Question

I'm using the following code to make HTTP POST request to the gcm server.
The code always returns "Unauthorized Error 401". I read that it is about the headers but can't figure out whats wrong.
Can anyone tell me what's wrong?
Is there any other way to send a gcm message?
Any help would be appreciated.
$api_key = "AIzaSyBhuPSdHmq6-************_qxSJr8d0";
$message = array("msg_url" => $msg_url, "msg_title" => $msg_title);
$url = 'https://android.googleapis.com/gcm/send';
$fields = array('registration_ids' => $ids,'data'=> array( "message" => $message ));
$headers = array('Authorization: key=' . $api_key,'Content-Type: application/json');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header'=> $headers ,
'method' => 'POST',
'content' => json_encode($fields),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);

Tested your code with my API key. I am able to send request to GCM and getting proper response. It seems like your API Key is having the problem
<?php
$msg_url = "http://msg.com";
$msg_title = "message_title";
$ids = array('reg_id_1', 'reg_id_2');
$api_key = "AIzaSyBhuPSdHmq6-************_qxSJr8d0";
$message = array("msg_url" => $msg_url, "msg_title" => $msg_title);
$url = 'https://android.googleapis.com/gcm/send';
$fields = array('registration_ids' => $ids,'data'=> array( "message" => $message ));
$headers = array('Authorization: key=' . $api_key,'Content-Type: application/json');
// use key 'http' even if you send the request to https://...
$options = array(
'http' => array(
'header'=> $headers ,
'method' => 'POST',
'content' => json_encode($fields),
),
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
var_dump($result);
?>
