Wysyłanie wiadomości na określone urządzenia
Aby wysłać powiadomienie na jedno konkretne urządzenie, przekaż token rejestracji urządzenia w sposób pokazany poniżej.
Node.js
// 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);
});
Java
// 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
// registration token.
String response = FirebaseMessaging.getInstance().send(message);
// Response is a message ID string.
System.out.println("Successfully sent message: " + response);
Python
# This registration token comes from the client FCM SDKs.

},
token=registration_token,
)
# Send a message to the device corresponding to the provided
# registration token.
response = messaging.send(message)
# Response is a message ID string.
print('Successfully sent message:', response)
Go
// Obtain a messaging.Client from the App.
ctx := context.Background()

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

if err != nil {

}
// Response is a message ID string.
fmt.Println("Successfully sent message:", response)
C#

// registration token.
string response = await FirebaseMessaging.DefaultInstance.SendAsync(message);
// Response is a message ID string.
Console.WriteLine("Successfully sent message: " + response);
W przypadku powodzenia każda metoda wysyłania zwraca identyfikator wiadomości. Firebase Admin SDK zwraca ciąg identyfikatora w formacie projects/{project_id}/messages/{message_id}.
Wysyłanie jednej wiadomości na kilka urządzeń
Pakiety SDK administratora FCM umożliwiają wysyłanie wiadomości do wielu odbiorców na listę tokenów rejestracji urządzeń. Możesz używać tej funkcji, gdy musisz wysłać tę samą wiadomość na dużą liczbę urządzeń. Możesz określić maksymalnie 500 tokenów rejestracji urządzenia na wywołanie.
Zwracana wartość zawiera listę tokenów, która odpowiada kolejności tokenów wejściowych. Jest to przydatne, gdy chcesz sprawdzić, które tokeny spowodowały błędy, a następnie odpowiednio je obsłużyć.

Wysyłanie listy wiadomości
Pakiety Admin SDK obsługują wysyłanie listy zawierającej maksymalnie 500 wiadomości. Za pomocą tej funkcji możesz tworzyć niestandardowe zestawy wiadomości i wysyłać je do różnych odbiorców, w tym do tematów lub konkretnych tokenów rejestracji urządzenia. Możesz na przykład użyć tej funkcji, gdy chcesz wysyłać do różnych odbiorców nieco odmienne komunikaty.
