Is it possible to use Firebase's FCM to send apns push notifications to an ios device?
Desired Workflow:
iOS app sends request to my .NET server to provide it the push token. My .NET server will handle all push notifications. So I assume this would be http requests to firebase and firebase would send out the notification?
Is this workflow possible?
I have worked with Android Applications using Firebase's FCM.. so i think there must be way to work with ios.
here is the snippet of code for sending push notification using fcm in c#.
NotifBooking objnotif = new NotifBooking();
string ApplicationID = "AIzaSyCBM20ZXXXXXXXXXXjog3Abv88";
string SENDER_ID = "962XXXXXXX";
var value = "Alert :" + Message + ""; //message text box
WebRequest tRequest;
tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send"); tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", ApplicationID)); tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
tRequest.ContentType = "application/json";
var data1 = new
{
to = "" + dt.Rows[i]["RegId"].ToString().Trim() + "",//Device RegID
priority = "high",
notification = new
{
body = Message,
title = Heading,
is_background = true,
image = "abc.com/images/1_icon.png",
appicon = "abc.com/images/1_icon.png",
sound = "default"
},
data = new
{
//body = Message,
//is_background=false,
//title = "Test FCM",
//appicon = "myicon",
image = "abc.com/images/1_icon.png"
},
};
Console.WriteLine(data1);
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data1);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
string str = sResponseFromServer;
}
}
}
}
objnotif.data = json;
}
You should get device token from Firebase and register the current user in backend side with the same token.
After that, you can send push notifications from your backend.
Put this code in AppDelegate class.
Call InitAPNS() from FinishedLaunching.
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
//TODO: save token and register one in backend side
Settings.DeviceTokenFCM = InstanceId.SharedInstance.Token;
}
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
ShowPushMessage(userInfo);
}
private void ShowPushMessage(NSDictionary userInfo)
{
if (userInfo != null)
{
try
{
var apsDictionary = userInfo["aps"] as NSDictionary;
var alertDictionary = apsDictionary?["alert"] as NSDictionary;
var body = alertDictionary?["body"].ToString();
var title = alertDictionary?["title"].ToString();
var window = UIApplication.SharedApplication.KeyWindow;
var vc = window.RootViewController;
var alert = UIAlertController.Create(title, body, UIAlertControllerStyle.Alert);
alert.AddAction(UIAlertAction.Create("OK", UIAlertActionStyle.Cancel, null));
vc.PresentViewController(alert, animated: true, completionHandler: null);
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
}
private void InitAPNS()
{
// Monitor token generation
InstanceId.Notifications.ObserveTokenRefresh(TokenRefreshNotification);
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
UNUserNotificationCenter.Current.RequestAuthorization(UNAuthorizationOptions.Alert | UNAuthorizationOptions.Sound | UNAuthorizationOptions.Sound, (granted, error) =>
{
if (granted)
{
InvokeOnMainThread(UIApplication.SharedApplication.RegisterForRemoteNotifications);
}
});
}
else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
new NSSet());
UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
UIApplication.SharedApplication.RegisterForRemoteNotifications();
}
else
{
UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}
Firebase.Core.App.Configure();
}
private void TokenRefreshNotification(object sender, NSNotificationEventArgs e)
{
ConnectToFCM();
}
private void ConnectToFCM()
{
var tokenFirebase = InstanceId.SharedInstance.Token;
////registation token in background thread
System.Threading.Tasks.Task.Run(() =>
{
if (!string.IsNullOrEmpty(tokenFirebase))
{
Firebase.CloudMessaging.Messaging.SharedInstance.SetApnsToken(tokenFirebase, ApnsTokenType.Production);
}
});
Messaging.SharedInstance.ShouldEstablishDirectChannel = true;

I am using this code to send notification message by C# with GCM, using Winforms, Webforms, whatever. Now I want to send to FCM (Firebase Cloud Messaging). Should I update my code? :
public class AndroidGCMPushNotification
{
public AndroidGCMPushNotification()
{
//
// TODO: Add constructor logic here
//
}
public string SendNotification(string deviceId, string message)
{
string SERVER_API_KEY = "server api key";
var SENDER_ID = "application number";
var value = message;
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", SERVER_API_KEY));
tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + deviceId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close();
dataStream.Close();
tResponse.Close();
return sResponseFromServer;
}
}
but the GCM was changed to FCM. Is this same code to send the notification?
Where can I find the SERVER_API_KEY? Is the same solution?
firebase cloud messaging with c#:
working all .net platform (asp.net, .netmvc, .netcore)
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
//serverKey - Key from Firebase cloud messaging server
tRequest.Headers.Add(string.Format("Authorization: key={0}", "AIXXXXXX...."));
//Sender Id - From firebase project setting
tRequest.Headers.Add(string.Format("Sender: id={0}", "XXXXX.."));
tRequest.ContentType = "application/json";
var payload = new
{
to = "e8EHtMwqsZY:APA91bFUktufXdsDLdXXXXXX..........XXXXXXXXXXXXXX",
priority = "high",
content_available = true,
notification = new
{
body = "Test",
title = "Test",
badge = 1
},
data = new
{
key1 = "value1",
key2 = "value2"
}
};
string postbody = JsonConvert.SerializeObject(payload).ToString();
Byte[] byteArray = Encoding.UTF8.GetBytes(postbody);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
if (dataStreamResponse != null) using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
//result.Response = sResponseFromServer;
}
}
}
}
Here is another approach of writing Notification Service inside ASP.Net REST API.
public async Task<bool> NotifyAsync(string to, string title, string body)
{
try
{
// Get the server key from FCM console
var serverKey = string.Format("key={0}", "Your server key - use app config");
// Get the sender id from FCM console
var senderId = string.Format("id={0}", "Your sender id - use app config");
var data = new
{
to, // Recipient device token
notification = new { title, body }
};
// Using Newtonsoft.Json
var jsonBody = JsonConvert.SerializeObject(data);
using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
{
httpRequest.Headers.TryAddWithoutValidation("Authorization", serverKey);
httpRequest.Headers.TryAddWithoutValidation("Sender", senderId);
httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
var result = await httpClient.SendAsync(httpRequest);
if (result.IsSuccessStatusCode)
{
return true;
}
else
{
// Use result.StatusCode to handle failure
// Your custom error handler here
_logger.LogError($"Error sending notification. Status Code: {result.StatusCode}");
}
}
}
}
catch (Exception ex)
{
_logger.LogError($"Exception thrown in Notify Service: {ex}");
}
return false;
}

I have posted this answer as this question was viewed most and this server side code was written in VS 2015 in C# for sending push notification either single device based on device id or subscribed topic to Xamarin Android app
public class FCMPushNotification
{
public FCMPushNotification()
{
// TODO: Add constructor logic here
}
public bool Successful
{
get;
set;
}
public string Response
{
get;
set;
}
public Exception Error
{
get;
set;
}
public FCMPushNotification SendNotification(string _title, string _message, string _topic)
{
FCMPushNotification result = new FCMPushNotification();
try
{
result.Successful = true;
result.Error = null;
// var value = message;
var requestUri = "https://fcm.googleapis.com/fcm/send";
WebRequest webRequest = WebRequest.Create(requestUri);
webRequest.Method = "POST";
webRequest.Headers.Add(string.Format("Authorization: key={0}", YOUR_FCM_SERVER_API_KEY));
webRequest.Headers.Add(string.Format("Sender: id={0}", YOUR_FCM_SENDER_ID));
webRequest.ContentType = "application/json";
var data = new
{
// to = YOUR_FCM_DEVICE_ID, // Uncoment this if you want to test for single device
to="/topics/"+_topic, // this is for topic
notification=new
{
title=_title,
body=_message,
//icon="myicon"
}
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
webRequest.ContentLength = byteArray.Length;
using (Stream dataStream = webRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse webResponse = webRequest.GetResponse())
{
using (Stream dataStreamResponse = webResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
}
}
}
}
catch(Exception ex)
{
result.Successful = false;
result.Response = null;
result.Error = ex;
}
return result;
}
}
and its uses
// start sending push notification to apps
FCMPushNotification fcmPush = new FCMPushNotification();
fcmPush.SendNotification("your notificatin title", "Your body message","news");
// end push notification
Yes, you should update your code to use Firebase Messaging interface.
There's a GitHub Project for that here.

Based on Teste's code .. I can confirm the following works. I can't say whether or not this is "good" code, but it certainly works and could get you back up and running quickly if you ended up with GCM to FCM server problems!
public AndroidFCMPushNotificationStatus SendNotification(string serverApiKey, string senderId, string deviceId, string message)
{
AndroidFCMPushNotificationStatus result = new AndroidFCMPushNotificationStatus();
try
{
result.Successful = false;
result.Error = null;
var value = message;
WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", serverApiKey));
tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + deviceId + "";
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
using (Stream dataStream = tRequest.GetRequestStream())
{
dataStream.Write(byteArray, 0, byteArray.Length);
using (WebResponse tResponse = tRequest.GetResponse())
{
using (Stream dataStreamResponse = tResponse.GetResponseStream())
{
using (StreamReader tReader = new StreamReader(dataStreamResponse))
{
String sResponseFromServer = tReader.ReadToEnd();
result.Response = sResponseFromServer;
}
}
}
}
}
catch (Exception ex)
{
result.Successful = false;
result.Response = null;
result.Error = ex;
}
return result;
}

You need change url from https://android.googleapis.com/gcm/send to https://fcm.googleapis.com/fcm/send and change your app library too. this tutorial can help you https://firebase.google.com/docs/cloud-messaging/server#implementing-http-connection-server-protocol
Try to send a json object.
Replace this:
tRequest.ContentType = " application/x-www-form-urlencoded;charset=UTF-8";
string postData = "collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message=" + value + "&data.time=" + System.DateTime.Now.ToString() + "®istration_id=" + deviceId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
For this:
tRequest.ContentType = "application/json";
var data = new
{
to = deviceId,
notification = new
{
body = "This is the message",
title = "This is the title",
icon = "myicon"
}
};
var serializer = new JavaScriptSerializer();
var json = serializer.Serialize(data);
Byte[] byteArray = Encoding.UTF8.GetBytes(json);
Here's the code for server side firebase cloud request from C# / Asp.net.
Please note that your client side should have same topic.
e.g.
FirebaseMessaging.getInstance().subscribeToTopic("news");
public String SendNotificationFromFirebaseCloud()
{
var result = "-1";
var webAddr = "https://fcm.googleapis.com/fcm/send";
var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add("Authorization:key=" + YOUR_FIREBASE_SERVER_KEY);
httpWebRequest.Method = "POST";
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = "{\"to\": \"/topics/news\",\"data\": {\"message\": \"This is a Firebase Cloud Messaging Topic Message!\",}}";
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
result = streamReader.ReadToEnd();
}
return result;
}

I write this code and It's worked for me .

var senderId = "3333333333333";
var result = "-1";
var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://fcm.googleapis.com/fcm/send");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Headers.Add(string.Format("Authorization: key={0}", serverKey));
httpWebRequest.Headers.Add(string.Format("Sender: id={0}", senderId));
httpWebRequest.Method = "POST";
var payload = new
{
notification = new
{
title = title,
body = msg,
sound = "default"
},
data = new
{
info = data
},
to = fcmToken,
priority = "high",
content_available = true,
};
var serializer = new JavaScriptSerializer();
using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
string json = serializer.Serialize(payload);
streamWriter.Write(json);
streamWriter.Flush();
}
var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))

Following Approach, I have used for writing Firebase Notification Service inside ASP.Net REST API.
public async Task<bool> NotifyAsync(string to, string title, string body)
{
try
{
//Server key from FCM console
var serverKey = string.Format("key={0}", "Provide your Server key here from Fibase console");
//Sender id from FCM console
var senderId = string.Format("id={0}", "Provide your Sender Id here from Firebase Console");
var data = new
{
to, // Recipient device token
notification = new { title, body }
};
// Using Newtonsoft.Json
var jsonBody = JsonConvert.SerializeObject(data);
using (var httpRequest = new HttpRequestMessage(HttpMethod.Post, "https://fcm.googleapis.com/fcm/send"))
{
httpRequest.Headers.TryAddWithoutValidation("Authorization", serverKey);
httpRequest.Headers.TryAddWithoutValidation("Sender", senderId);
httpRequest.Content = new StringContent(jsonBody, Encoding.UTF8, "application/json");
using (var httpClient = new HttpClient())
{
var result = await httpClient.SendAsync(httpRequest);
if (result.IsSuccessStatusCode)
{
return true;
}
else
{
// Use result.StatusCode to handle failure
// Your custom error handler here
return false;
}
}
}
}
catch (Exception ex)
{
throw ex;
}
return false;
}

I am developing a Windows phone 8 app that needs to upload photos to amazon s3 storage. However, I find that this is impossible since the HttpClient time out after about 60 seconds regardless of what timeout setting I use.
Is there really no way to upload large files from Windows Phone?
BackgroundTransferRequest is useless since it cannot send the neccessary metadata with file uploads.
I use this code (which times out):
using (var httpClient = new HttpClient())
{
httpClient.Timeout = TimeSpan.FromMinutes(30);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, m_uploadUrl);
httpContent.Headers.Add("Keep-Alive", "true");
request.Content = httpContent; // 3-5 Mb file
response = await httpClient.SendAsync(request);
statusCode = response.StatusCode;
}
I also tried PostAsync(), but same result. After about 60 sec the call completes with a status code 400 or 404. This is not a server timeout. IPhone and Android apps use the same service. No problems there.
Any ideas on how to upload files that takes more than 60 seconds to send?
I too faced similar things. The timeout glitch.
Check if you could use another class instead of HttpClient.
WebClient may be.
Check if this helps you:
http://blog.anthonybaker.me/2013/06/how-to-upload-file-from-windows-phone.html
and even this:
http://chriskoenig.net/2011/08/19/upload-files-from-windows-phone/
I got things working for me with those.
I've used several days now to implement a new uploader and get all the details working. I used HttpWebRequest with the async methods and split the file into chuncks. Finally I got it working and it uploads without the timeout. Here is the complete code:

I want to upload files to FTPS and SFTP. My code is currently using FtpWebRequest object to upload to FTP. What changes or class should I use to upload to FTP, FTPS and SFTP servers?
SFTP is not a built-in protocol for .NET, you'll have to use a third-party library, like SharpSSH; however, FTP and FTPS are. There are a number of third-party libraries both commercial and OpenSource (SSH Factory for .NET , Rebex SFTP for .NET/.NET CF, SharpSSH - A Secure Shell (SSH) library for .NET, Compare SFTP (SSH File Transfer Protocol) components for .NET (C#, VB.NET) - SecureBlackbox®) and you'll need to do some research to determine which one will best suit your needs.
Here's a sample console app I wrote that does FTP and FTPS using the .NET Framework's FtpWebRequest:

In ASP.NET 4.5 is the HttpTaskAsyncHandler. You can use it like this:
public class MyHandler : HttpTaskAsyncHandler {
public override async Task ProcessRequestAsync(HttpContext context) {
await WhateverAsync(context);
}
}
You need to implmement IHttpAsyncHandler rather than IHttpHandler and register it as such in the web.config file. Browsers will also observe connection limits, so make sure IIS is configured properly to handle multiple connections, keep-alive, etc.
