Question

我已经为我的应用创建了推送通知，它工作正常，但没有在所有设备上发送通知令牌。

首先我有一个数据库名称“member”，它包含id，username，password，token

然后我创建这个php函数来发送通知

<?php
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'XXXXXXXXXXXXXXXXX' );
include 'DatabaseConfig.php';

 $con = mysqli_connect($HostName,$HostUser,$HostPass,$DatabaseName);
$checktoken = "SELECT token FROM member";
$results = $con->query($checktoken);

if ($results ->num_rows > 0) {

while($row = $results->fetch_assoc()){

$regid = array($row["token"]);
echo "" .$row["token"]. " ";
}
}else{
echo "No result";
}

// prep the bundle
$msg = array
(
    'body'  => 'here is a message. message',
    'title'     => 'This is a title. title',
    'subtitle'  => 'This is a subtitle. subtitle',
    'tickerText'    => 'Ticker text here...Ticker text here...Ticker text here',
    'vibrate'   => 1,
    'sound'     => 'mySound',
    'largeIcon' => 'large_icon',
    'smallIcon' => 'small_icon'
);
$fields = array
(
    'registration_ids'  => $regid,
    'notification'          => $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;

代码只发送到一个设备，当我尝试在浏览器中访问它时显示

它有2个设备，但为什么它只发送到一个设备令牌？我的代码的任何修复？

供您参考第一个设备以eY0-0uIUDsA开头：第二个从dPEPzRFjnIo开始：

您在每次循环迭代时都会覆盖$ regid的内容。在循环外定义数组：

public abstract class ContextBase
    {
        public abstract bool SaveChanges();

        protected bool SaveChanges(ObjectContext context)
        {
            try
            {
                int i = context.SaveChanges();

                if (i == 0)
                    return false;

                return true;
            }
            catch (Exception ex)
            {
                throw new EntityContextException("SaveChanges failed.", ex);
            }
        }

        public abstract void DeleteObject(object entity);

        protected void DeleteObject(ObjectContext context, object entity)
        {
            try
            {
                context.DeleteObject(entity);
            }
            catch (Exception ex)
            {
                throw new EntityContextException("DeleteObject failed.", ex);
            }
        }




    }

另外，最好带上在if的正分支内发送通知的代码，只有在得到结果时才需要发送。

在数据库MySql中的所有令牌上发送推送通知
