我在跟着 http://javapapers.com/android/google-cloud-messaging-gcm-for-android-and-push-notifications/？通过GCM发送推送通知.一切正常,但是我可以将推送通知发送到一个设备.注册另一个设备将替换以前设备的注册ID.我在 http://javapapers.com/android/android-multicast-notification-using-google-cloud-messaging-gcm/试过了Shardool提供的解决方案？但它不工作.

任何建议都会有很大的帮助.

以下是我的gcm.php代码,注册设备并发送推送通知,但仅限于最近注册的单个设备.

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($ch,CURLOPT_RETURNTRANSFER,CURLOPT_POSTFIELDS,json_encode($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;
}   
?>

            <div>                                
                <textarea rows="2" name="message" cols="23" placeholder="Message to transmit via   GCM"></textarea>
            </div>
            <div><input type="submit"  value="Send Push Notification via GCM" /></div>
        </form>
        <p><h3><?php echo $pushStatus; ?></h3></p>        
    </body>

请告诉我如何在GCMRegid.txt中存储多个设备注册ID,并将通知发送到每个注册的设备

在这里,我用mysql重写了PHP,而不是从文件中检索密钥.在这种情况下,我从表中检索所有的regIds并将它们放在一个数组中,并将其传递给sendPushNotification函数以将消息推送到所有.这里有2个文件,一个连接到数据库,另一个用于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,);

    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_SSL_VERIFYPEER,false);
    curl_setopt($ch,json_encode($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;
    }   
}
?>

    <head>
        <title>Google Cloud Messaging (GCM) Server in PHP</title>
    </head>
    <body>
    <h1>Google Cloud Messaging (GCM) Server in PHP</h1>
    <form method = 'POST' action = 'gcm.php/?push=1'>
        <div>
            <textarea rows = 2 name = "message" cols = 23 placeholder = 'Messages to Transmit via GCM'></textarea>
        </div>
        <div>
            <input type = 'submit' value = 'Send Push Notification via GCM'>
        </div>
        <p><h3><?php echo $pushStatus ?></h3></p>
    </form>

所有你需要做的是创建一个数据库,其中具有id,regId和name作为列的users表.

希望这是你正在寻找的
