这里我使用 mysql 重写了 php，而不是从文件中检索密钥。在这种情况下，我检索所有regIds从表中将它们放入一个数组中，并将其传递给 sendPushNotification 函数以将消息推送给所有人。这里有 2 个文件，一个用于连接数据库，一个用于 GCM：
连接.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,
'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)) {
echo 'OK';
exit;
}
}
?>

您所要做的就是创建一个数据库，其中包含一个用户表，其中包含 id、regId 和 name 作为列。
希望这就是您正在寻找的
