FCM推送通知问题:-"错误":"未注册"

我正在使用FCM向Android发送推送通知这一奇怪的问题.

目标: - 发送推送通知时出错

下面是我有功能向Android发送推送通知的场景

 public static function SendMultipleNotificationAndroid($groups)
    {
        //your api key SERVER API KEY
        $apiKey = Yii::$app->params['android_api_key'];
        $url = 'https://fcm.googleapis.com/fcm/send';    
        $headers = array(
            'Authorization:key=' . $apiKey,
            'Content-Type: application/json'
        );

        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

        foreach($groups as $resG){
            $users  = $resG['users'];                        
            $msg    =   $resG['message'];
            $type    =   $resG['notification_type'];
            $notification_data    =   $resG['notification_data'];

            $deviceTokens = [];
            foreach($users as $resUser){
                $deviceTokens[] = $resUser['device_token'];
                //Add  Friend badge count +1
                Common::AddRemoveBadgeCount($resUser['user_id']);
            }
            if(!empty($deviceTokens)){
                $fields = array(
                    'registration_ids' => $deviceTokens,
                    'priority'     => 'high', 
                    'collapse_key' => $resG['notification_type'],   
                    'time_to_live' => 2419200,     
                    "click_action" =>"NotificationListingActivity",     
                    'data'         => [                  
                        "title"             => "ProjectName",
                        "body"              => $resG['message'],
                        "action_tag"        => $resG['notification_type'],
                        "message"           => $resG['message'],
                        'notification_type' => $type,
                        'notification_data' => $notification_data,
                        'sound'             => 'default',
                    ]
                );
                //Print result 
                p($ch,0);
                curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
                curl_exec($ch);
            }            
        }
        curl_close($ch);
    }

所以问题是当我发送单个通知它工作正常,但当我发送多个通知我每次都有错误

Resource id #5
{"multicast_id":4818908994630396118,"success":1,"failure":1,"canonical_ids":0,"results":[{"error":"NotRegistered"},{"message_id":"0:1487136045570022%c3bae3c6002e9358"}]}

Resource id #5
{"multicast_id":5218359780835228544,"success":1,"failure":1,"canonical_ids":0,"results":[{"error":"NotRegistered"},{"message_id":"0:1487136046618669%c3bae3c6002e9358"}]}

当我们调试代码时,我们在数据库中没有设备令牌,没有防火墙停止发送推送通知.

每次我打电话给我以上的功能

"错误": "NotRegistered"

任何帮助,将不胜感激.

提前致谢.

不太了解PHP,但最近我在另一个项目中遇到了同样的问题,我已经解决了这个问题:

首先参考: 在哪里可以找到Firebase Cloud Messaging的API KEY？

并获取更新的API密钥,如下面的快照所示

根据该文档,因为移动设备测试不再安装您的应用程序

如果是NotRegistered,则应从服务器数据库中删除注册ID,因为应用程序已从设备卸载,或者客户端应用程序未配置为接收消息.
