Ionic 4中的自动更新徽章编号

Question

我正在使用离子4 Cordova插件FCM。 除非我刷新该应用程序，否则我的应用程序通知工作完美，但徽章编号不会增加。 因此，我的问题是如何在没有iOS中刷新应用程序的情况下增加徽章计数？

我的通知有效载荷格式

<?php
        function send_notification ($token, $message, $title)
        {
                 $path_to_firebase_cm = 'https://fcm.googleapis.com/fcm/send';
                
            
                $fields = array(
                   'registration_ids' => $token,
                    'notification' => array('title' => $title, 'body' => $message ),
                    'data' => array('message' => $message, 'title' => $title  ),
                    'sound' => 'default',
                    'badge' => 1
                
                );

                $headers = array(
            'Authorization:key=AAAAF.....,
            'Content-Type:application/json'
        );      
        $ch = curl_init();
 
        curl_setopt($ch, CURLOPT_URL, $path_to_firebase_cm); 
        curl_setopt($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_IPRESOLVE, CURL_IPRESOLVE_V4 ); 
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
        $result = curl_exec($ch);
       
        curl_close($ch);

        return $result;
      
        }

        
        $message=$_POST["message"];
        $title=$_POST["title"];
        include_once 'config.php';
        $sql = "SELECT mem_tokenid FROM user";
        $result = mysqli_query($conn,$sql);
        
      //var_dump(result);
        if(mysqli_num_rows($result) > 0 ){
                while ($row = mysqli_fetch_assoc($result)) {
                        $tokens[] = $row["mem_tokenid"];
                }
        }
    var_dump($tokens);

  
        mysqli_close($conn);
        $message = $message;
        $title = $title;
        $message_status = send_notification($tokens, $message, $title);
        echo $message_status;
 ?> 

我在这里做错了吗？
