notificaciones - send notification android php
Enviando notificaciones push a múltiples dispositivos Android usando GCM (4)
Aquí reescribí el php usando mysql en lugar de recuperar las claves del archivo. En este caso, recupero todos los registros de la tabla, los coloco en una matriz y los paso a la función sendPushNotification para enviar el mensaje a todos. Aquí tiene 2 archivos, uno para conectarse a la base de datos y otro para 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;
}
}
?>

todo lo que tiene que hacer es crear una base de datos que tenga una tabla de usuarios con ID, registro y nombre como columnas.
Espero que esto sea lo que buscas.
Estoy siguiendo http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/ ? para enviar notificaciones push a través de GCM. Todo funciona bien, pero puedo enviar notificaciones push a un solo dispositivo. El registro de otro dispositivo reemplaza la identificación de registro del dispositivo anterior. Probé la solución provista por Shardool en http://javapapers.com/android/android-multicast-notification-using-google-cloud-messaging-gcm/ ? pero no está funcionando.
Cualquier sugerencia sería de gran ayuda.
Aquí están mis códigos gcm.php que registran el dispositivo y envían notificaciones push, pero solo a un único dispositivo registrado recientemente.
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;
}
?>

Por favor, dígame cómo almaceno los identificadores de registro de múltiples dispositivos en GCMRegid.txt y envío notificaciones a cada uno de los dispositivos registrados
El envío de notificaciones push a múltiples dispositivos es igual a lo que enviamos a dispositivos individuales. Simplemente almacene el token de registro de todos los dispositivos registrados en su servidor. Y cuando llame a la notificación de inserción con curl (supongo que está utilizando php como servidor) coloque todo el ID de registro en una matriz. Este es un código de muestra.
<?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'');
}
}
El siguiente código funciona para enviar notificaciones a todos los usuarios registrados:
<?php
header("Access-Control-Allow-Origin: *");
$db_host = ''localhost''; //hostname
$db_user = ''''; // username
$db_password = ''''; // password
$db_name = ''''; //database name
$link = mysqli_connect($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)
{
// API access key from Google API''s Console
// replace API
define( ''API_ACCESS_KEY'', ''AIdfSyCd8ha2wop84LKtpQvRmCEiY8ZLpeTg2-o'');
$registrationIds = array($to);
$msg = array
(
''message'' => $message,
''title'' => $title,
''vibrate'' => 1,
''sound'' => 1
// you can also add images, additionalData
);
$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 );
echo $result;
}
?>

He modificado un poco el gcm.php anterior para satisfacer mis necesidades:
- La página se debe volver a cargar automáticamente en su forma original después de enviar una notificación de inserción.
- Debe mostrar el número de usuarios registrados.
- GCM no permite más de 1000 registros a la vez. Así que debería abordar esa situación. (enviando paquetes de 1000 pushnotifications en un bucle).

EDITAR:
He reescrito el código PHP con algunas mejoras y usando MySqli (en lugar de MySql). Está en Github .
