Retrieve fcmToken of current device FCM node.js
I want to check if the fcmToken of the current device is the same as the fcmToken of the user who is sending the message, and if so, not send the notification. Is it possible to retrieve the fcmToken in the node.js file, and if not, are there any other possible ways I can prevent the user from receiving notifications about his own message.
Below I posted the node.js code: Users are basically just receiving notifications based on topics (convoIds) that they are subscribed to.
exports.observeMessages = functions.database.ref('/conversation_messages/{topicId}/{messageId}')
.onCreate((snapshot, context) => {
var topic = context.params.topicId;
var messageId = context.params.messageId;
var message = snapshot.val();
return admin.database().ref('/conversations/' + topic).once('value', snapshot => {
var conversation = snapshot.val(); // This gives us the conversation name
return admin.database().ref('/users/' + message.senderId).once('value', snapshot => {
var user = snapshot.val();
var notification = {
notification: {
title: conversation.conversationName,
body: user.username + ': ' + message.text
},
apns: {
payload: {
aps: {
sound: 'default'
}
}
},
data: {
conversationId: topic
},
topic: topic
};
admin.messaging().send(notification)
.then((response) => {
// Response is a message ID string.
console.log('Successfully sent message:' + notification + 'to topic: ' + topic, response);
return response
})
.catch((error) => {
console.log('Error sending message:', error);
throw new Error("Error sending message");
});
})
})
})
