我有一个基于GCM通知的应用程序,每当新用户安装应用程序时,其GCM注册ID存储在php服务器的mysql数据库中,现在我已经编写了一个脚本来向所有注册用户发送通知,如下所示
<?php
//------------------------------
// Payload data you want to send
// to Android device (will be
// accessible via intent extras)
//------------------------------
//------------------------------
// The recipient registration IDs
// that will receive the push
// (Should be stored in your DB)
//
// Read about it here:
// http://developer.android.com/google/gcm/
//------------------------------
if(isset($_GET['message']))
{
$msg = $_GET['message'];
$data = array("price" => $msg);
$ids = array();
require_once dirname(__FILE__). '/db_connect.php';;
$db = new DB_CONNECT();
$qry = mysql_query("SELECT gcm_regid FROM gcm_users");
while($row = mysql_fetch_array($qry))
{
$ids[] = $row['gcm_regid'];
}
//$ids = array( 'abc', 'def' );
//------------------------------
// Call our custom GCM function
//------------------------------
//------------------------------
// Define custom GCM function
//------------------------------
function sendGoogleCloudMessage( $data, $ids )
{
//------------------------------
// Replace with real GCM API
// key from Google APIs Console
//
// https://code.google.com/apis/console/
//------------------------------
$apiKey = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';
//------------------------------
// Define URL to GCM endpoint
//------------------------------
$url = 'https://android.googleapis.com/gcm/send';
//------------------------------
// Set GCM post variables
// (Device IDs and push payload)
//------------------------------
$post = array(
'registration_ids' => $ids,
'data' => $data,
);
//------------------------------
// Set CURL request headers
// (Authentication and type)
//------------------------------
$headers = array(
'Authorization: key='. $apiKey,
'Content-Type: application/json'
);
//------------------------------
// Initialize curl handle
//------------------------------
$ch = curl_init();
//------------------------------
// Set URL to GCM endpoint
//------------------------------
curl_setopt( $ch, CURLOPT_URL, $url );
//------------------------------
// Set request method to POST
//------------------------------
curl_setopt( $ch, CURLOPT_POST, true );
//------------------------------
// Set our custom headers
//------------------------------
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
//------------------------------
// Get the response back as
// string instead of printing it
//------------------------------
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
//------------------------------
// Set post data as JSON
//------------------------------
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $post ) );
//------------------------------
// Actually send the push!
//------------------------------
$result = curl_exec( $ch );
//------------------------------
// Error? Display it!
//------------------------------
if ( curl_errno( $ch ) )
{
echo 'GCM error: ' . curl_error( $ch );
}
//------------------------------
// Close curl handle
//------------------------------
curl_close( $ch );
//------------------------------
// Debug GCM response
//------------------------------
echo $result;
}
sendGoogleCloudMessage( $data, $ids );
}
?>
我担心的是,当用户群庞大时,脚本可能会失败。
答案 0 :(得分:0)
如果您向GCM发送同一请求中的1000多个注册ID,您的脚本将失败。您必须确保每个请求最多包含1000个注册ID。
registration_ids 包含设备列表的字符串数组 (注册ID)接收消息。它必须至少包含1个 和最多1000个注册ID 。要发送多播消息,您 必须使用JSON。对于将单个消息发送到单个设备,您 可以使用只有1个注册ID或纯文本的JSON对象 (见下文)。请求必须包含收件人 - 这可以是a 注册ID,注册ID数组或notification_key。 必需的。
