Question

我正在关注this tutorial以了解GCM系统。我对这部分有疑问：

可以向每个注册用户发送消息，但是如何更改该代码以便我可以向所有已注册的设备发送单个消息？

我已经找到了答案：

sending push notifications to multiple android devices using GCM

和

Sending Push Notification on multiple devices

（几乎相同的问题） - 但找不到解决我问题的任何答案。

<body>
        <?php
        include_once 'db_functions.php';
        $db = new DB_Functions();
        $users = $db->getAllUsers();
        if ($users != false)
            $no_of_users = mysql_num_rows($users);
        else
            $no_of_users = 0;
        ?>
        <div class="container">
            <h1>No of Devices Registered: <?php echo $no_of_users; ?></h1>
            <hr/>
            <ul class="devices">
                <?php
                if ($no_of_users > 0) {
                    ?>
                    <?php
                    while ($row = mysql_fetch_array($users)) {
                        ?>

                                <div class="clear"></div>

                        No Users Registered Yet!
                    </li>
                <?php } ?>
            </ul>
        </div>
    </body>

我试图更改代码，但是我的更改不起作用..

我想将所有regID作为数组放入sendPushNofiy ...

    <body>
            <?php
            include_once 'db_functions.php';
            $db = new DB_Functions();
            $users = $db->getAllUsers();
            if ($users != false)
                $no_of_users = mysql_num_rows($users);
            else
                $no_of_users = 0;
            ?>
            <div class="container">
                <h1>No of Devices Registered: <?php echo $no_of_users; ?></h1>

while(($row = mysql_fetch_array($users))) {

    }

有了这个，我可以将所有的regid放入数组行......但是如何将数组转移到表单中呢？

   while ($row = mysql_fetch_array($users)) {
          $rows[] = $row["gcm_regid"];

          }

我的问题是如何发送我的数组＆＃34; row＆＃34;发送send_message.php？

$ registatoin_ids = array（$ regId）; ＆LT;＆LT;它确实已经处理数组，但我的输入仅使用一个值，我想传输数组^^

编辑： send_message.php

if (isset($_GET["regId"]) && isset($_GET["message"])) {
    $regId = $_GET["regId"];
    $message = $_GET["message"];

    include_once './GCM.php';

    $gcm = new GCM();

    $registatoin_ids = array($regId);
    $message = array("price" => $message);

    $result = $gcm->send_notification($registatoin_ids, $message);

    echo $result;
}
?>

Answer 1

您有责任维护所有注册用户的注册ID列表。没有API调用来向所有注册用户发送消息。您可以向GCM服务器发送最多1000个注册ID的请求。如果您拥有超过1000个注册用户，则必须将其拆分为多个请求。

Answer 2

<?php
if (isset($_GET["message"])) {
  include_once 'db_functions.php';
  $db = new DB_Functions();
  $users = $db->getAllUsers();
  $regIds = array();
  if ($users != false){
    while ($row = mysqli_fetch_array($users)) {
        $regIds[] = $row["gcm_regid"];
    }
  }

  include_once './GCM.php';

  $gcm = new GCM();

  $registatoin_ids = $regIds;
  $message = "array("price" => $_GET["message"])";

  $result = $gcm->send_notification($registatoin_ids, $message);

  echo $result;
}
?>
