Come posso integrare il nuovo Google Cloud Messaging in un back-end PHP?
Risposte:
Questo codice invierà un messaggio GCM a più ID di registrazione tramite 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 $result;
}
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
<?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(

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

?>
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
è un grande no-no. Se, per qualche motivo, il tuo server che esegue questo codice PHP non è in grado di verificare il certificato SSL utilizzato dai server di Google, puoi dire a cURL con cosa verificare. Esempio: unitstep.net/blog/2009/05/05/…
È facile da fare. Il codice cURL che si trova sulla pagina che Elad Nava ha messo qui funziona. Elad ha commentato l'errore che sta ricevendo.
Stringa che descrive un errore che si è verificato durante l'elaborazione del messaggio per quel destinatario. I valori possibili sono gli stessi documentati nella tabella sopra, più "Non disponibile" (il che significa che i server GCM erano occupati e non potevano elaborare il messaggio per quel particolare destinatario, quindi poteva essere riprovato).
Ho già impostato un servizio che sembra funzionare (ish) e finora tutto ciò che ho ricevuto sono resi non disponibili da Google. Molto probabilmente questo cambierà presto.
Per rispondere alla domanda, usa PHP, assicurati che Zend Framework sia nel tuo percorso di inclusione e usa questo codice:
<?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);
E lì ce l'abbiamo. Un esempio funzionante (funzionerà presto) dell'utilizzo di Googles nuovo GCM in Zend Framework PHP.
Dopo aver cercato a lungo finalmente sono riuscito a capire di cosa avevo esattamente bisogno, connettendomi al GCM usando PHP come linguaggio di scripting lato server, il seguente tutorial ci darà un'idea chiara di come impostare tutto ciò di cui abbiamo bisogno per iniziare con GCM
Notifiche push Android tramite Google Cloud Messaging (GCM), PHP e MySQL
In realtà ho questo lavoro ora in un ramo nel mio albero Zend_Mobile: https://github.com/mwillbanks/Zend_Mobile/tree/feature/gcm
Questo sarà rilasciato con ZF 1.12, tuttavia, dovrebbe darti alcuni ottimi esempi su come farlo.
Ecco una breve demo su come funzionerebbe ....
<?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, $v['message_id']);
}
}
Molte esercitazioni non sono aggiornate e anche il codice corrente non tiene conto dell'aggiornamento dei dispositivi di registrazione o dell'annullamento della registrazione dei dispositivi. Se tali elementi rimangono deselezionati, alla fine causeranno problemi che impediscono la ricezione dei messaggi. http://forum.loungekatt.com/viewtopic.php?t=63#p181
Inoltre puoi provare questo pezzo di codice, fonte :
<?php
define("GOOGLE_API_KEY", "AIzaSyCJiVkatisdQ44rEM353PFGbia29mBVscA");
define("GOOGLE_GCM_URL", "https://android.googleapis.com/gcm/send");
function send_gcm_notify($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);
?>
Nello script sopra basta cambiare:
Da "YOURKEY" a Chiave API per Chiave server della console API.
"REGISTRATO_ID" con l'ID di registrazione del dispositivo
"COLLAPSE_KEY" con la chiave che hai richiesto
"MESSAGGIO" con il messaggio che desideri inviare
Fammi sapere se riscontri problemi in questo, sono in grado di ricevere notifiche utilizzando lo stesso script.
Puoi usare questa libreria PHP disponibile su packagist:
https://github.com/CoreProc/gcm-php
Dopo averlo installato puoi farlo:
$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();
}
Ecco una libreria che ho forkato da CodeMonkeysRU.
Il motivo per cui ho biforcato è perché Google richiede un backoff esponenziale. Uso un server redis per mettere in coda i messaggi e inviare nuovamente dopo un tempo prestabilito.
L'ho anche aggiornato per supportare iOS.

So che questa è una risposta tardiva, ma può essere utile per coloro che vogliono sviluppare app simili con l'attuale formato FCM (GCM è stato deprecato).
