GCM con PHP (Google Cloud Messaging)

Actualización: GCM está en desuso, use FCM

¿Cómo puedo integrar el nuevo Google Cloud Messaging en un backend PHP?

Este código enviará un mensaje GCM a múltiples ID de registro a través de PHP CURL.

// Payload data you want to send to Android device(s)
// (it will be accessible via intent extras)    
$data = array('message' => 'Hello World!');

// The recipient registration tokens for this notification
// https://developer.android.com/google/gcm/    
$ids = array('abc', 'def');

// Send push notification via Google Cloud Messaging
sendPushNotification($data, $ids);

function sendPushNotification($data, $ids) {
    // Insert real GCM API key from the Google APIs Console
    // https://code.google.com/apis/console/        
    $apiKey = 'abc';

    // Set POST request body
    $post = array(
                    'registration_ids'  => $ids,
                    'data'              => $data,
                 );

    // Set CURL request headers 
    $headers = array( 
                        'Authorization: key=' . $apiKey,
                        'Content-Type: application/json'
                    );

    // Initialize curl handle       
    $ch = curl_init();

    // Set URL to GCM push endpoint     
    curl_setopt($ch, CURLOPT_URL, 'https://gcm-http.googleapis.com/gcm/send');

    // Set request method to POST       
    curl_setopt($ch, CURLOPT_POST, true);

    // Set custom request headers       
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

    // Get the response back as string instead of printing it       
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    // Set JSON post data
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($post));

    // Actually send the request    
    $result = curl_exec($ch);

    // Handle errors
    if (curl_errno($ch)) {
        echo 'GCM error: ' . curl_error($ch);
    }

    // Close curl handle
    curl_close($ch);

    // Debug GCM response       
    echo $result;
}

<?php
    // Replace with the real server API key from Google APIs
    $apiKey = "your api key";

    // Replace with the real client registration IDs
    $registrationIDs = array( "reg id1","reg id2");

    // Message to be sent
    $message = "hi Shailesh";

    // Set POST variables
    $url = 'https://android.googleapis.com/gcm/send';

    $fields = array(
        'registration_ids' => $registrationIDs,
        'data' => array( "message" => $message ),
    );
    $headers = array(
        'Authorization: key=' . $apiKey,
        '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);
    //curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    // curl_setopt($ch, CURLOPT_POST, true);
    // curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode( $fields));

    // Execute post
    $result = curl_exec($ch);

    // Close connection
    curl_close($ch);
    echo $result;
    //print_r($result);
    //var_dump($result);
?>

Es facil de hacer. El código cURL que está en la página que Elad Nava ha puesto aquí funciona. Elad ha comentado sobre el error que está recibiendo.

Cadena que describe un error que ocurrió mientras procesaba el mensaje para ese destinatario. Los valores posibles son los mismos que se documentan en la tabla anterior, además de "No disponible" (lo que significa que los servidores GCM estaban ocupados y no podían procesar el mensaje para ese destinatario en particular, por lo que podrían volver a intentarlo).

Ya tengo un servicio configurado que parece estar funcionando (ish), y hasta ahora todo lo que he recibido son devoluciones no disponibles de Google. Es más que probable que esto cambie pronto.

Para responder la pregunta, use PHP, asegúrese de que Zend Framework esté en su ruta de inclusión y use este código:

<?php
    ini_set('display_errors',1);
    include"Zend/Loader/Autoloader.php";
    Zend_Loader_Autoloader::getInstance();

    $url = 'https://android.googleapis.com/gcm/send';
    $serverApiKey = "YOUR API KEY AS GENERATED IN API CONSOLE";
    $reg = "DEVICE REGISTRATION ID";

    $data = array(
            'registration_ids' => array($reg),
            'data' => array('yourname' => 'Joe Bloggs')
    );

    print(json_encode($data));

    $client = new Zend_Http_Client($url);
    $client->setMethod('POST');
    $client->setHeaders(array("Content-Type" => "application/json", "Authorization" => "key=" . $serverApiKey));
    $client->setRawData(json_encode($data));
    $request = $client->request('POST');
    $body = $request->getBody();
    $headers = $request->getHeaders();
    print("<xmp>");
    var_dump($body);
    var_dump($headers);

Y ahí lo tenemos. Un ejemplo funcional (funcionará pronto) del uso del nuevo GCM de Google en Zend Framework PHP.

Después de buscar durante mucho tiempo, finalmente puedo descubrir qué es exactamente lo que necesito, Conectarme al GCM usando PHP como lenguaje de script del lado del servidor. El siguiente tutorial nos dará una idea clara de cómo configurar todo lo que necesitamos para comenzar. con GCM

Notificaciones push de Android con Google Cloud Messaging (GCM), PHP y MySQL

De hecho, esto funciona ahora en una rama en mi árbol Zend_Mobile: https://github.com/mwillbanks/Zend_Mobile/tree/feature/gcm

Esto se lanzará con ZF 1.12, sin embargo, debería darle algunos buenos ejemplos sobre cómo hacer esto.

Aquí hay una demostración rápida de cómo funcionaría ...

<?php
require_once 'Zend/Mobile/Push/Gcm.php';
require_once 'Zend/Mobile/Push/Message/Gcm.php';

$message = new Zend_Mobile_Push_Message_Gcm();
$message->setId(time());
$message->addToken('ABCDEF0123456789');
$message->setData(array(
    'foo' => 'bar',
    'bar' => 'foo',
));

$gcm = new Zend_Mobile_Push_Gcm();
$gcm->setApiKey('MYAPIKEY');

$response = false;

try {
    $response = $gcm->send($message);
} catch (Zend_Mobile_Push_Exception $e) {
    // all other exceptions only require action to be sent or implementation of exponential backoff.
    die($e->getMessage());
}

// handle all errors and registration_id's
foreach ($response->getResults() as $k => $v) {
    if ($v['registration_id']) {
        printf("%s has a new registration id of: %s\r\n", $k, $v['registration_id']);
    }
    if ($v['error']) {
        printf("%s had an error of: %s\r\n", $k, $v['error']);
    }
    if ($v['message_id']) {
        printf("%s was successfully sent the message, message id is: %s", $k, $v['message_id']);
    }
}

Muchos de los tutoriales están desactualizados, e incluso el código actual no tiene en cuenta cuándo se actualizan los dispositivos de registro o se anula el registro de los dispositivos. Si esos elementos no se controlan, eventualmente causará problemas que impiden recibir mensajes. http://forum.loungekatt.com/viewtopic.php?t=63#p181

También puedes probar este código, fuente :

<?php
    define("GOOGLE_API_KEY", "AIzaSyCJiVkatisdQ44rEM353PFGbia29mBVscA");
    define("GOOGLE_GCM_URL", "https://android.googleapis.com/gcm/send");

    function send_gcm_notify($reg_id, $message) {
        $fields = array(
            'registration_ids'  => array( $reg_id ),
            'data'              => array( "message" => $message ),
        );

        $headers = array(
            'Authorization: key=' . GOOGLE_API_KEY,
            'Content-Type: application/json'
        );

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, GOOGLE_GCM_URL);
        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);
        if ($result === FALSE) {
            die('Problem occurred: ' . curl_error($ch));
        }

        curl_close($ch);
        echo $result;
    }

    $reg_id = "APA91bHuSGES.....nn5pWrrSz0dV63pg";
    $msg = "Google Cloud Messaging working well";

    send_gcm_notify($reg_id, $msg);

<?php

function sendMessageToPhone($deviceToken, $collapseKey, $messageText, $yourKey) {    
    echo "DeviceToken:".$deviceToken."Key:".$collapseKey."Message:".$messageText
            ."API Key:".$yourKey."Response"."<br/>";

    $headers = array('Authorization:key=' . $yourKey);    
    $data = array(    
        'registration_id' => $deviceToken,          
        'collapse_key' => $collapseKey,
        'data.message' => $messageText);  
    $ch = curl_init();    

    curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");    
    if ($headers)    
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);    
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);    
    curl_setopt($ch, CURLOPT_POST, true);    
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);    
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);    

    $response = curl_exec($ch);    
    var_dump($response);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);    
    if (curl_errno($ch)) {
        return false;
    }    
    if ($httpCode != 200) {
        return false;
    }    
    curl_close($ch);    
    return $response;    
}  

$yourKey = "YOURKEY";
$deviceToken = "REGISTERED_ID";
$collapseKey = "COLLAPSE_KEY";
$messageText = "MESSAGE";
echo sendMessageToPhone($deviceToken, $collapseKey, $messageText, $yourKey);
?>

En el script anterior solo cambia:

"TU CLAVE" a la clave API a la clave del servidor de la consola API.
"REGISTRADO_ID" con el ID de registro de su dispositivo
"COLLAPSE_KEY" con la clave que requirió
"MENSAJE" con el mensaje que desea enviar

Avíseme si tiene algún problema al respecto. Puedo recibir notificaciones con éxito utilizando el mismo script.

Puede usar esta biblioteca PHP disponible en packagist:

https://github.com/CoreProc/gcm-php

Después de instalarlo, puede hacer esto:

$gcmClient = new GcmClient('your-gcm-api-key-here');

$message = new Message($gcmClient);

$message->addRegistrationId('xxxxxxxxxx');
$message->setData([
    'title' => 'Sample Push Notification',
    'message' => 'This is a test push notification using Google Cloud Messaging'
]);

try {

    $response = $message->send();

    // The send() method returns a Response object
    print_r($response);

} catch (Exception $exception) {

    echo 'uh-oh: ' . $exception->getMessage();

}

Aquí hay una biblioteca que bifurqué de CodeMonkeysRU.

La razón por la que bifurqué fue porque Google requiere un retroceso exponencial. Uso un servidor redis para poner en cola los mensajes y reenviarlos después de un tiempo establecido

También lo actualicé para admitir iOS.
