Wysyłanie wiadomości za pomocą pakietu Firebase Admin SDK

Jeśli nie masz jeszcze skonfigurowanego Firebase Admin SDK, postępuj zgodnie z przewodnikiem, aby skonfigurować Firebase Admin SDK na serwerze.

Włączanie interfejsu FCM HTTP v1 API

  1. W konsoli Firebase kliknij Ustawienia > Ogólne. Następnie kliknij kartę Cloud Messaging.

  2. włączyć interfejs Cloud Messaging API;

Autoryzowanie konta usługi z innego projektu

Możesz wysyłać wiadomości z jednego projektu („projekt docelowy”) przy użyciu konta usługi w innym projekcie („projekt nadawcy”). Pozwala to scentralizować zarządzanie kontami usługi w jednym projekcie, a jednocześnie wysyłać wiadomości w imieniu innych osób. Aby dowiedzieć się, jak to zrobić, wykonaj te czynności:

  1. W projekcie nadawcy sprawdź, czy interfejs Firebase Cloud Messaging API jest włączony. Sprawdź, czy jest włączona w konsoli Firebase, klikając Ustawienia > Ogólne. Następnie kliknij kartę Cloud Messaging.

  2. W projekcie nadawcy utwórz konto usługi.

  3. W projekcie docelowym przypisz rolę administratora interfejsu Firebase Cloud Messaging API do adresu e-mail konta usługi. Możesz to zrobić na stronie Administracja > Uprawnienia w konsoli Google Cloud. Ta rola umożliwia kontu usługi z projektu nadawcy wysyłanie wiadomości do projektu docelowego.

  4. Zainicjuj pakiet SDK za pomocą pliku klucza konta usługi projektu nadawcy i identyfikatora projektu docelowego.

Wysyłanie wiadomości na określone urządzenia

Aby wysłać powiadomienie na jedno konkretne urządzenie, możesz kierować je na identyfikator instalacji Firebase (FID) lub token rejestracji.

Node.js

// This installation ID comes from the client FCM SDKs.
const fid = 'YOUR_REGISTERED_FID';

const message = {
  data: {
    score: '850',
    time: '2:45'
  },
  fid: fid
};

// Send a message to the device corresponding to the provided FID.
getMessaging().send(message)
  .then((response) => {
    // Response is a message ID string.
    console.log('Successfully sent message:', response);
  })
  .catch((error) => {
    console.log('Error sending message:', error);
  });

W przypadku powodzenia każda metoda wysyłania zwraca identyfikator wiadomości. Funkcja Firebase Admin SDK zwraca ciąg identyfikatora w formacie projects/{project_id}/messages/{message_id}.

Wysyłanie jednej wiadomości na wiele urządzeń

Pakiety SDK administratora FCM umożliwiają wysyłanie wiadomości do wielu odbiorców na listę identyfikatorów instalacji Firebase (FID) lub tokenów rejestracji urządzenia. Możesz używać tej funkcji, gdy musisz wysłać tę samą wiadomość na dużą liczbę urządzeń. Możesz określić do 500 identyfikatorów FID lub tokenów na wywołanie.

Wartość zwracana zawiera listę odpowiedzi, która odpowiada kolejności docelowych danych wejściowych, identyfikatorów FID lub tokenów. Jest to przydatne, gdy chcesz sprawdzić, które miejsca docelowe spowodowały błędy. Jeśli podane są zarówno tokeny, jak i identyfikatory FID, najpierw przetwarzane są tokeny, a potem identyfikatory FID.
