使用Google Cloud Messaging (GCM),PHP 开发Android Push Notifications (安卓推送通知)

class GCM {

    function __construct() {

    }

    /**
     * Sending Push Notification
     */

        // 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;
    }

}

$device_id = "APA91bFFBkpObz-rK";
$registatoin_ids = array($device_id);

$message = array("data" => "test content from finley");

$gcm = new GCM();
