envoi de notifications Push à plusieurs Android utilisant GCM

Je suis http://javapapers.com/Android/google-cloud-messaging-gcm-for-Android-and-Push-notifications/ ? pour envoyer des notifications Push via GCM. Tout fonctionne bien, mais je peux envoyer une notification Push à un seul appareil. L'enregistrement d'un autre appareil remplace l'ID d'enregistrement de l'appareil précédent. J'ai essayé la solution fournie par Shardool en http://javapapers.com/Android/android-multicast-notification-using-google-cloud-messaging-gcm/ ? mais ça ne marche pas.

Toute suggestion serait d'une grande aide.

Voici mes gcm.php codes qui enregistrent l'appareil et envoient des notifications Push, mais uniquement à un seul appareil enregistré récemment.

gcm.php 

<?php
//generic php function to send GCM Push notification
function sendPushNotificationToGCM($registatoin_ids, $message) {
    //Google cloud messaging GCM-API url
    $url = 'https://Android.googleapis.com/gcm/send';
    $fields = array(
        'registration_ids' => $registatoin_ids,
        'data' => $message,
    );
    // Google Cloud Messaging GCM API Key
    define("GOOGLE_API_KEY", "MY_KEY");       
    $headers = array(
        'Authorization: key=' . GOOGLE_API_KEY,
        'Content-Type: application/json'
    );
    $ch = curl_init();
    curl_setopt($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));
    $result = curl_exec($ch);             
    if ($result === FALSE) {
        die('Curl failed: ' . curl_error($ch));
    }
    curl_close($ch);
    return $result;
}
?>
<?php
//this block is to post message to GCM on-click
$pushStatus = "";   
if ( ! empty($_GET["Push"])) { 
    $gcmRegID  = file_get_contents("GCMRegId.txt");
    $pushMessage = $_POST["message"];   
    if (isset($gcmRegID) && isset($pushMessage)) {      
        $gcmRegIds = array($gcmRegID);
        $message = array("m" => $pushMessage);  
        $pushStatus = sendPushNotificationToGCM($gcmRegIds, $message);
    }       
}
//this block is to receive the GCM regId from external (mobile apps)
if ( ! empty($_GET["shareRegId"])) {
    $gcmRegID  = $_POST["regId"]; 
    file_put_contents("GCMRegId.txt",$gcmRegID);
    echo "Ok!";
    exit;
}

Veuillez me dire comment stocker plusieurs ID d'enregistrement d'appareil dans GCMRegid.txt et envoyer des notifications à chacun des appareils enregistrés

Ici, j'ai réécrit le php en utilisant mysql plutôt que de récupérer les clés du fichier. Dans ce cas, je récupère tous les regIds de la table et les mets dans un tableau et je les passe à la fonction sendPushNotification pour pousser le message à tous. ici vous avez 2 fichiers, un pour se connecter à la base de données et un pour GCM:

connect.php:

<?php

    $db_Host = "localhost";
    $db_user = "root"; //change to your database username, it is root by default
    $db_pass = '';     //change to your database password, for XAMPP it is nothing for WAMPP it is root
    $db_db = 'gcmFirst'; //change to your database name

    if(!@mysql_connect($db_Host, $db_user, $db_pass) || !@mysql_select_db($db_db)) {
        die('couldnt connect to database ' .mysql_error());
    }

?>

gcm.php

<?php
require 'connect.php';

function sendPushNotification($registration_ids, $message) {

    $url = 'https://Android.googleapis.com/gcm/send';
    $fields = array(
        'registration_ids' => $registration_ids,
        'data' => $message,
    );

    define('GOOGLE_API_KEY', 'AIzaSyCjctNK2valabAWL7rWUTcoRA-UAXI_3ro');

    $headers = array(
        'Authorization:key=' . GOOGLE_API_KEY,
        'Content-Type: application/json'
    );
    echo json_encode($fields);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    $result = curl_exec($ch);
    if($result === false)
        die('Curl failed ' . curl_error());

    curl_close($ch);
    return $result;

}

$pushStatus = '';

if(!empty($_GET['Push'])) {

    $query = "SELECT regId FROM users";
    if($query_run = mysql_query($query)) {

        $gcmRegIds = array();
        while($query_row = mysql_fetch_assoc($query_run)) {

            array_Push($gcmRegIds, $query_row['regId']);

        }

    }
    $pushMessage = $_POST['message'];
    if(isset($gcmRegIds) && isset($pushMessage)) {

        $message = array('message' => $pushMessage);
        $pushStatus = sendPushNotification($gcmRegIds, $message);

    }   
}

if(!empty($_GET['shareRegId'])) {

    $gcmRegId = $_POST['regId'];
    $query = "INSERT INTO users VALUES ('', '$gcmRegId')";
    if($query_run = mysql_query($query)) {
        echo 'OK';
        exit;
    }   
}
?>

tout ce que vous avez à faire est de créer une base de données qui a une table d'utilisateurs avec id, regId et name comme colonnes.

J'espère que c'est ce que vous cherchez

J'ai modifié ce qui précède gcm.php un peu pour répondre à mes besoins:

  1. La page doit être automatiquement rechargée dans son format d'origine après l'envoi de la notification Push.
  2. Il doit indiquer le nombre d'utilisateurs enregistrés.
  3. GCM n'autorise pas plus de 1 000 regId à la fois. Il devrait donc s'attaquer à cette situation. (envoi de paquets de 1000 pushnotifications en boucle).

L'envoi d'une notification push à plusieurs appareils est identique à l'envoi à un appareil individuel. Enregistrez simplement le jeton d'enregistrement de tous les appareils enregistrés sur votre serveur. Et lorsque vous appelez la notification Push avec curl (je suppose que vous utilisez php comme côté serveur) Mettez tous les identifiants d'enregistrement dans un tableau. Ceci est un exemple de code

<?php
//Define your GCM server key here 
define('API_ACCESS_KEY', 'your server api key');

//Function to send Push notification to all 
function sendToAll($message)
{
    $db = new DbOperation();
    $tokens = $db->getAllToken();
    $regTokens = array();
    while($row = $tokens->fetch_assoc()){
        array_Push($regTokens,$row['token']);
    }
    sendNotification($regTokens,$message);
}


//function to send Push notification to an individual 
function sendToOne($email,$message){
    $db = new DbOperation();
    $token = $db->getIndividualToken($email);
    sendNotification(array($token),$message);
}


//This function will actually send the notification
function sendNotification($registrationIds, $message)
{
    $msg = array
    (
        'message' => $message,
        'title' => 'Android Push Notification using Google Cloud Messaging',
        'subtitle' => 'www.simplifiedcoding.net',
        'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',
        'vibrate' => 1,
        'sound' => 1,
        'largeIcon' => 'large_icon',
        'smallIcon' => 'small_icon'
    );

    $fields = array
    (
        'registration_ids' => $registrationIds,
        'data' => $msg
    );

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

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://Android.googleapis.com/gcm/send');
    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);
    curl_close($ch);

    $res = json_decode($result);

    $flag = $res->success;
    if($flag >= 1){
        header('Location: index.php?success');
    }else{
        header('Location: index.php?failure');
    }
}

Le code suivant fonctionne pour moi d'envoyer une notification à tous les utilisateurs enregistrés:

<?php
header("Access-Control-Allow-Origin: *"); 

$db_Host = 'localhost'; //hostname
$db_user = ''; // username
$db_password = ''; // password

$link = mysqli_connect($db_Host,$db_user,$db_password, $db_name);




$query = "select * from device_notification_id";
$result = mysqli_query ($link,$query);
while($row=mysqli_fetch_array($result)){
                
                $device_to[] =  $row[device_id];
                
                        
}



if(isset($_POST['submit'])){

$title=$_POST['title'];
$message=$_POST['message'];
for($i=0 ; $i< sizeof($device_to) ; $i++)
{
//echo $to[$i];

$to = $device_to[$i];

sendPush($to,$title,$message);
}


}
        function sendPush($to,$title,$message)

                $registrationIds = array($to);
                
                

        $msg = array
        (
        'message' => $message,
        'title' => $title,
        'vibrate' => 1,
        'sound' => 1

// you can also add images, additionalData
);


        $fields = array
        (
