Nachricht mit dem Firebase Admin SDK senden

Falls Sie Firebase Admin SDK noch nicht eingerichtet haben, folgen Sie der Anleitung, um Firebase Admin SDK auf Ihrem Server einzurichten.

FCM HTTP v1 API aktivieren

Rufen Sie in der Firebase Console Einstellungen > Allgemein auf. Klicken Sie dann auf den Tab „Cloud Messaging“.
Aktivieren Sie die Cloud Messaging API.

Dienstkonto aus einem anderen Projekt autorisieren

Sie können Nachrichten für ein Projekt, das „Zielprojekt“, senden und dabei ein Dienstkonto in einem anderen Projekt, dem „Absenderprojekt“, verwenden. So können Sie die Verwaltung von Dienstkonten in einem Projekt zentralisieren und gleichzeitig Nachrichten im Namen anderer senden. Gehen Sie dazu so vor:

Achten Sie darauf, dass die Firebase Cloud Messaging API im Absenderprojekt aktiviert ist. Prüfen Sie in der Firebase-Konsole unter Einstellungen > Allgemein, ob die Funktion aktiviert ist. Klicken Sie dann auf den Tab „Cloud Messaging“.
Erstellen Sie im Absenderprojekt ein Dienstkonto.
Weisen Sie im Zielprojekt der E-Mail-Adresse für das Dienstkonto die Rolle „Firebase Cloud Messaging API Admin“ zu. Dies erfolgt in der Google Cloud Console auf der Seite IAM & Verwaltung > IAM. Mit dieser Rolle kann das Dienstkonto des Absenderprojekts Nachrichten an das Zielprojekt senden.

Initialisieren Sie das SDK mit der Schlüsseldatei für das Dienstkonto des Senderprojekts und der Projekt-ID des Zielprojekts.

Node.js

import { initializeApp, applicationDefault } from 'firebase-admin/app';

initializeApp({
  // The credential is configured to be the sender project's service
  // account key via the environment variable GOOGLE_APPLICATION_CREDENTIALS
  credential: applicationDefault(),
  projectId: '<TARGET_PROJECT_ID>',
});

Java

FirebaseOptions options = FirebaseOptions.builder()
    // The credential is configured to be the sender project's service
    // account key via the environment variable GOOGLE_APPLICATION_CREDENTIALS
    .setCredentials(GoogleCredentials.getApplicationDefault())
    .setProjectId("<TARGET_PROJECT_ID>")
    .build();

FirebaseApp.initializeApp(options);

Python

import firebase_admin

app_options = {'projectId': '<TARGET_PROJECT_ID>'}
# Initialize with the default credential, i.e. the sender project's service
# account key, stored in GOOGLE_APPLICATION_CREDENTIALS
default_app = firebase_admin.initialize_app(options=app_options)

Go

config := &firebase.Config{ProjectID: "<TARGET_PROJECT_ID>"}
// Initialize with the default credential, i.e. the sender project's service
// account key, stored in GOOGLE_APPLICATION_CREDENTIALS
app, err := firebase.NewApp(context.Background(), config)
if err != nil {
        log.Fatalf("error initializing app: %v\n", err)
}

C#

FirebaseApp.Create(new AppOptions()
{
    // The credential is configured to be the sender project's service
    // account key via the environment variable GOOGLE_APPLICATION_CREDENTIALS
    Credential = GoogleCredential.GetApplicationDefault(),
    ProjectId = "<TARGET_PROJECT_ID>",
});

Nachrichten an bestimmte Geräte senden

Wenn Sie eine Nachricht an ein einzelnes, bestimmtes Gerät senden möchten, können Sie entweder die Firebase-Installations-ID (FID) oder das Registrierungstoken des Geräts als Ziel verwenden.

Node.js

FID verwenden (empfohlen):

// 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);
  });

Registrierungstoken verwenden (eingestellt):

// This registration token comes from the client FCM SDKs.
const registrationToken = 'YOUR_REGISTRATION_TOKEN';

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

// Send a message to the device corresponding to the provided
// registration token.
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);
  });

    .setFid(fid)
    .build();

// Send a message to the device corresponding to the provided FID.
String response = FirebaseMessaging.getInstance().send(message);
// Response is a message ID string.
System.out.println("Successfully sent message: " + response);

Registrierungstoken verwenden (eingestellt):

// This registration token comes from the client FCM SDKs.
String registrationToken = "YOUR_REGISTRATION_TOKEN";

// See documentation on defining a message payload.
Message message = Message.builder()
    .putData("score", "850")
    .putData("time", "2:45")
    .setToken(registrationToken)
    .build();

// Send a message to the device corresponding to the provided

Bei Erfolg gibt jede Sendemethode eine Nachrichten-ID zurück. Der Firebase Admin SDK gibt den ID-String im Format projects/{project_id}/messages/{message_id} zurück.

Eine Nachricht an mehrere Geräte senden

Mit den Admin FCM SDKs können Sie eine Nachricht an eine Liste von Firebase-Installations-IDs (FIDs) oder Geräteregistrierungstokens senden. Sie können diese Funktion verwenden, wenn Sie dieselbe Nachricht an eine große Anzahl von Geräten senden müssen. Sie können bis zu 500 FIDs und/oder Tokens pro Aufruf angeben.

Der Rückgabewert enthält eine Liste von Antworten, die der Reihenfolge der Eingabeziele, FIDs und/oder Tokens entspricht. Dies ist nützlich, wenn Sie prüfen möchten, bei welchen Zielen Fehler aufgetreten sind. Wenn sowohl Tokens als auch FIDs angegeben werden, werden zuerst die Tokens und dann die FIDs verarbeitet.

Liste mit Nachrichten senden

Mit den Admin-SDKs können Sie eine Liste mit bis zu 500 Nachrichten senden. Mit dieser Funktion können Sie einen benutzerdefinierten Satz von Nachrichten erstellen und an verschiedene Empfänger senden, darunter Themen, Firebase-Installations-IDs (FIDs) oder Geräteregistrierungstokens. Sie können diese Funktion beispielsweise verwenden, wenn Sie unterschiedliche Nachrichten an verschiedene Zielgruppen senden müssen.
