什么是GCM?

Google Cloud  Messaging (GCM) 是Google提供的一个服务,用来从服务端向安卓设备发送推送通知。

GCM分为客户端和服务端开发。

这里我们只介绍服务端开发。其实过程非常简单,只需利用PHP发送POST数据。

有两个关键地方需要获得一个是API Key

一个是Device ID 这个可以从安卓客户端开发者获得。

class GCM {

    public $api_key = "AIzaSyAU3wZs9raik-mHQ";

    function __construct() {

    }

    /**
* Sending Push Notification
*/
public function send_notification($registatoin_ids, $message) { // Set POST variables
$url = 'https://android.googleapis.com/gcm/send'; $fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
); $headers = array(
'Authorization: key=' . $this->api_key,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init(); // Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); // Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
} // Close connection
curl_close($ch);
return $result;
} }

运行程序

$device_id = "APA91bFFBkpObz-rK";
$registatoin_ids = array($device_id); $message = array("data" => "test content from finley"); $gcm = new GCM();
$result = $gcm->send_notification($registatoin_ids, $message);
echo $result;
