Aquí hay una biblioteca que bifurqué de CodeMonkeysRU.
La razón por la que me bifurqué fue porque Google requiere un retroceso exponencial. Utilizo un servidor redis para poner en cola los mensajes y reenviarlos después de un tiempo establecido.
También lo he actualizado para soportar iOS.
De hecho, ahora tengo esto funcionando 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'']);
}
}
Después de buscar por mucho tiempo, finalmente puedo averiguar qué es exactamente lo que necesitaba. Conectándome al GCM usando PHP como lenguaje de programación 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 utilizando Google Cloud Messaging (GCM), PHP y MySQL
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 se produjo al procesar el mensaje para ese destinatario. Los valores posibles son los mismos que se documentaron en la tabla anterior, además de "No disponible" (lo que significa que los servidores GCM estaban ocupados y no pudieron procesar el mensaje para ese destinatario en particular, por lo que se podría volver a intentar).
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 de trabajo (que funcionará pronto) del uso de la nueva GCM de Google en Zend Framework 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;
}
Muchos de los tutoriales están desactualizados, e incluso el código actual no tiene en cuenta cuando se actualizan los dispositivos de registro o se anulan el registro de los dispositivos. Si esos elementos no están marcados, eventualmente causará problemas que impiden que se reciban mensajes. http://forum.loungekatt.com/viewtopic.php?t=63#p181
Puedes usar esta biblioteca de PHP disponible en packagist:
https://github.com/CoreProc/gcm-php
Después de instalarlo puedes 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: '' . $exception->getMessage();
}
También puedes probar este fragmento de código, source :
<?php
define("GOOGLE_API_KEY", "AIzaSyCJiVkatisdQ44rEM353PFGbia29mBVscA");
define("GOOGLE_GCM_URL", "https://android.googleapis.com/gcm/send");
function send_gcm_notify($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);
utilizar esta
function pnstest(){
$data = array(''post_id''=>''12345'',''title''=>''A Blog post'', ''message'' =>''test msg'');

$fields = array();
$fields[''data''] = $data;
if(is_array($target)){
$fields[''registration_ids''] = $target;
}else{
$fields[''to''] = $target;
}
//header with content_type api key
$headers = array(
''Content-Type:application/json'',
''Authorization:key=''.$server_key
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$result = curl_exec($ch);
if ($result === FALSE) {
die(''FCM Send Error: '' . curl_error($ch));
}
curl_close($ch);
return $result;
}
<?php

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:
"Yourkey" a clave de API de servidor de claves de la consola de la API.
"REGISTRADO_ID" con el ID de registro de su dispositivo
"COLLAPSE_KEY" con la clave que requieres
"MENSAJE" con el mensaje que desea enviar
Avíseme si tiene algún problema con esto. Puedo recibir una notificación con éxito utilizando el mismo script.
