I am thinking about keeping all registration ids(push token) in DB and sending notifications to user from iPhone. I tried something like this but did not get any notification.
func sendPNMessage() {
FIRMessaging.messaging().sendMessage(
["body": "hey"],
to: TOKEN_ID,
withMessageID: "1",
timeToLive: 108)
}
What I am doing wrong or maybe it is impossible at all?
Currently it's not possible to send messages from the application itself.
You can send messages from the Firebase Web Console, or from a custom server using the server-side APIs.
What you might want to do is to contact a server (like via http call) and that server will send the message to the user.
This way ensure that the API-KEY of the server is protected.
PS: the sendMessage(..) api is called upstream feature, and can be used to send messages from your app to your server, if you server has an XMPP connection with the FCM server.
Yes you can send push notification through Firebase.Please make sure do NOT include the server-key into your client. There are ways "for not so great people" to find it and do stuff... The Proper way to achieve that is for your client to instruct your app-server to send the notification.
You have to send a HTTP-Post to the Google-API-Endpoint.
You need the following headers:
Content-Type: application/json
Authorization: key={your_server_key}
You can obtain your server key within in the Firebase-Project.
HTTP-Post-Content: Sample
{
"notification": {
"title": "Notification Title",
"text": "The Text of the notification."
},
"project_id": "<your firebase-project-id",
"to":"the specific client-device-id"
}
Google Cloud Functions make it now possible send push notifications from device-to-device without an app server.
From the Google Cloud Functions documentation:
Developers can use Cloud Functions to keep users engaged and up to
date with relevant information about an app. Consider, for example, an
app that allows users to follow one another's activities in the app.
In such an app, a function triggered by Realtime Database writes to
store new followers could create Firebase Cloud Messaging (FCM)
notifications to let the appropriate users know that they have gained
new followers.
Example:
The function triggers on writes to the Realtime Database path where followers are stored.
The function composes a message to send via FCM.
FCM sends the notification message to the user's device.
Here is a demo project for sending device-to-device push notifications with Firebase and Google Cloud Functions.
Diego's answer is very accurate but there's also cloud functions from firebase it's very convenient to send notifications in every change in the db. For example let's say you're building chat application and sending notification in every new follower change.
This function sample is very good example.
For more information about cloud functions you can check official docs.
I have an app that has a "send feedback to developer" section. I also have a User collection in my firestore database. When a user logs into the app, I have that Users data update their FCM token with the following code in my SceneDelegate.swift:
import Firebase
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
authListener = Auth.auth().addStateDidChangeListener({ (auth, user) in
Auth.auth().removeStateDidChangeListener(self.authListener!)
if user != nil {
DispatchQueue.main.async {
let docRef = Firestore.firestore().collection("User").document((user?.email)!)
docRef.getDocument { (snapshot, error) in
guard let snapshot = snapshot else {return}
Messaging.messaging().token { token, error in
if let error = error {
print("Error fetching FCM registration token: \(error)")
} else if let token = token {
docRef.updateData(["FCMtoken":token])
print("FCM registration token: \(token)")
}
}
}
}
}
})
guard let _ = (scene as? UIWindowScene) else { return }
}
then in my feedback view controller i have this code to send my specific device (but you can look up/fetch which specific device you want in your database where the FCMtoken is stored where i have INSERT-DEVICE-TOKEN-HERE). The url to send to is "https://fcm.googleapis.com/fcm/send" and you can find YOUR-APP-FCM-KEY by going to your project settings in firebase, going to cloud messaging tab and its the server key.
func sendMePushNotification() {
let token = "INSERT-DEVICE-TOKEN-HERE"
if let url = URL(string: "https://fcm.googleapis.com/fcm/send") {
var request = URLRequest(url: url)
request.allHTTPHeaderFields = ["Content-Type":"application/json", "Authorization":"key=YOUR-APP-FCM-KEY"]
request.httpMethod = "POST"
request.httpBody = "{\"to\":\"\(token)\",\"notification\":{\"title\":\"Feedback Sent!\",\"body\":\"\(self.feedbackBox.text!)\",\"sound\":\"default\",\"badge\":\"1\"},\"data\": {\"customDataKey\": \"customDataValue\"}}".data(using: .utf8)
URLSession.shared.dataTask(with: request) { (data, urlresponse, error) in
if error != nil {
print("error")
} else {
print("Successfully sent!.....")
}
}.resume()
}
}
Use onesignal,you can send device to notifications or device to segments ,it can work with firebase in this way
Use onesignal functions to create a specific id,save it in a firebase database ,then when the id can be put in another function that is used to send a notification
Notes: 1-i am using it in my apps with firebase works perfectly
2-i can submit that code,just someone comments so i can find this answer

I would be very thankful for help with Push Notifications. My app has a chat where users can send text messages directly to each other. But without Push Notifications it doesn't make much sense. It is all set up on Firebase. How could I send Push Notifications from a specific device to a specific device? I did try Firebase Notifications and OneSignal due to a recommendation on Stackoverflow. But I am only able to trigger the notifications from Firebase or OneSignal directly and not from a specific device to a specific device.
Does someone has experience with this?
If your data is being stored in Firebease I would use Cloud Messaging for Push notifications as well. There are multiple ways to achieve this messaging notification functions, I will resume the one I think is the easiest.
Assuming you are using FCM and you have configured your app for it.
First of all you need to store the token of the users device, this would be stored as a string with each of the users info:
let token = Messaging.messaging().fcmToken
So in your Firebase DB, in each of your users object data you would have a key storing a string with the token, if you want the user to receive notifications in multiple devices, you must store the multiple tokens of the user using an array of strings, or even an array of objects and store the device type, etc. Thats your choice and your needs.
The ideal push notification environment is usually composed by a middle server that receive the request and manage and send the notification to the corresponding users, in this case you can skip this and send the not directly from your app, using FCM POST request service:
Example of how to build a FCM POST request to send a notification:
let url = URL(string: "https://fcm.googleapis.com/fcm/send")!
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.setValue("key=--HERE-GOES-YOUR-API-KEY--", forHTTPHeaderField: "Authorization")
request.httpMethod = "POST"
Here you put all not data, read the docs to understand all the keys and variables that you can send, yo would need to make a previous firebase request in which you get the device tokens.
var notData: [String: Any] = [
"to" : "HERE YOU PUT THE DEVICE TOKEN(s)",
"notification": [
title : "not title",
body : "not body",
icon : "not icon"
],
"data": [
//More notification data.
]
]
And then you send the post request, It will return an object if the notification was succeed and more data.
request.httpBody = notData.data(using: .utf8)
let task = URLSession.shared.dataTask(with: request) { data, response, error in
guard let data = data, error == nil else { // check for fundamental networking error
print("error=\(error)")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(response)")
}
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(responseString)")
}
task.resume()
I've been using this same solution for a mobile native app and a react web app and it works like a charm.
In Swift 4, everything that Karlo posted above works fine, except for the data(using:) function is not longer available.
That will need to be something like this:
request.httpBody = try? JSONSerialization.data(withJSONObject: notData, options: [])
Once I made that change everything compiled and worked beautifully.
You can target push notifications to a specific device easily. There's a tutorial given for that specific purpose here (https://firebase.google.com/docs/cloud-messaging/ios/first-message).
Now you can follow the below steps:
When the 'user' sends a message to 'other user', you can send the information of 'other user' to the server.
From server, you can send the push notification to the 'other user'
