问题描述
我下面http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/?通过GCM发送推送通知。一切工作正常，但是，我能够发送推送通知，只是一个设备。注册其他设备替换previous设备的注册ID。我试着在http://javapapers.com/android/android-multicast-notification-using-google-cloud-messaging-gcm/?但它不工作。任何的建议是有很大的帮助。
I am following http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/? to send push notifications via GCM. Everything works fine but, i am able to send push notification to just one device. Registering another device replaces registration id of previous device. I tried solution provided by Shardool in http://javapapers.com/android/android-multicast-notification-using-google-cloud-messaging-gcm/? but its not working. Any suggestion would be of great help.
下面是我的gcm.php codeS的注册设备并发送推送通知，但只注册过一个单一的设备
Here are my gcm.php codes that registers device and sends push notifications but, only to a single device registered recently
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;
}
?>

请告诉我，我怎么存储多个设备注册的ID在GCMRegid.txt并发送通知到每个登记的设备
Please tell me how do I store multiple device registration ids in GCMRegid.txt and send notifications to each of the registered device
推荐答案
在这里，我用mysql，而不是从检索文件中的按键改写了PHP。在这种情况下，我检索所有的 regIds 从表中，并把它们放入数组，并把它传递给sendPushNotification功能的消息推送到所有。在这里你有2个文件，一个用于连接到数据库，一个用于GCM：
Here I rewrote the php using mysql rather than retrieving the keys from file. In this case, I retrieve all the regIds from the table and put them in an array and pass it to sendPushNotification function to push the message to all. here you have 2 files, one for connect to database and one for GCM:
将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
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)) {

所有你需要做的就是创建一个具有用户表的id，REGID和名称列的数据库。
all you have to do is create a database that has a users table with id, regId and name as columns.
