Не удалось получить Push-уведомление от бэкэнда через FCM

Question

быстро, я разработал приложение для iOS и Android, у них есть одна и та же БД, и я применил Firebase для обоих проектов, согласно учебникам Google Firebase, но когда мой бэкэнд отправляет push-уведомление, я получаю уведомление на Android, но ничего не появляется на моем устройстве или консоли iOS.

Вот мой бэкенд код (PHP):

$message = array('message' => 'Blood Donation alert ', 
       'mobile' => $rdmob, 
       'name' => $rdname, 
       'bt' => $rdbt, 
       'rh' => $rdrh, 
       'loclat' =>$rdloclat, 
       'loclon' =>$rdloclon, 
       'locdetails' =>$BD_R_loc_details); 

sendMessageThroughGCM($tokens_arr, $message); 






function sendMessageThroughGCM($registatoin_ids, $message) 
{ 
    $url = 'https://android.googleapis.com/gcm/send'; 
    $fields = array(
     'registration_ids' => $registatoin_ids, 
     'data' => $message, 

    ); 
    define("GOOGLE_API_KEY", "AAAA3n_S2aE:APA91bFpFVn5XbhP_FeXXoZGkG9la94WTMsORZwKrzd-0sNKM8nbjM_E2jMcaAjaubMP11pgby4RFUllVAaUBcmkoOaOw7NG-Xa-JOhfY-UCq829Wa49yxw0IttAnSUge_P4Wmtg"); 
    $headers = array(
     'Authorization: key=' . GOOGLE_API_KEY, 
     '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_RETURNTRANSFER, true); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields)); 
    $result = curl_exec($ch); 
    if ($result === FALSE) { 
     die('Curl failed: ' . curl_error($ch)); 
    } 
    curl_close($ch); 
    echo json_encode($fields['data']); 
}

Примечания: - У меня есть APNS ce rtificate, и мое приложение успешно получает токен APNS и токен FCM.

- iOS получает уведомление успешно, только если я сделал это вручную, Firebase Console -> Уведомление -> Отправить новое уведомление (приложение для таргетинга iOS).

UPDATE:

PHP код обновление

$fields = array(
     'registration_ids' => $registatoin_ids, 
     'data' => $message, 
    'priority' => 'high', 

    ); 

Я назначен приоритет высокого к сообщению в настоящее время, и до сих пор не в состоянии получить его прошивку.

Answer 1

Я столкнулся с такой же проблемой и причиной, что формат загрузки для iPhone и Android отличается. Если формат полезной информации не содержит ключа «уведомления», вы не получите уведомления на своем iPhone.

Просьба сообщить разработчику PHP для создания отдельного формата полезной информации для приложений iOS и Android.

Другие мудрые создают такую ​​же полезную нагрузку, которая содержит как ключи «уведомлений», так и «данные» следующим образом.

{ "сообщение": { "маркер": "bk3RNwTe3H0: CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1 ...", "уведомление": { "Название": "Нажмите название", "тело": "Тело сообщения" }, "данные": { "Ник": "Ник", "номер": "номер" }} }
