Senden von Push an Android über C # mit FCM (Firebase Cloud Messaging)

Ich verwende diesen Code, um Benachrichtigungsnachrichten mit GCM von C # zu senden, Winforms, Webforms oder was auch immer. Jetzt möchte ich an FCM (Firebase Cloud Messaging) senden. Soll ich meinen Code aktualisieren? :

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() + "&registration_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;
    }
}

das GCM wurde jedoch in FCM geändert. Ist derselbe Code zum Senden der Benachrichtigung? Wo finde ich den SERVER_API_KEY? Ist die gleiche Lösung?

firebase Cloud Messaging mit c #: funktioniert auf allen .net-Plattformen (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
            },
        };

        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;

Hier ist ein weiterer Ansatz zum Schreiben des Benachrichtigungsdienstes in der 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;

Ich habe diese Antwort gepostet, da diese Frage am häufigsten angesehen wurde und dieser serverseitige Code in VS # 2015 für das Senden von Push-Benachrichtigungen geschrieben wurde, entweder als einzelnes Gerät basierend auf der Geräte-ID oder als abonniertes Thema für die 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;
    }
}

und seine Verwendung

// start sending Push notification to apps

Basierend auf Testes Code .. kann ich die folgenden Arbeiten bestätigen. Ich kann nicht sagen, ob dies "guter" Code ist oder nicht, aber es funktioniert auf jeden Fall und könnte Sie schnell wieder zum Laufen bringen, wenn Sie GCM-zu-FCM-Server-Probleme haben!

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() + "&registration_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;
                    }

Hier ist der Code für die serverseitige Firebase-Cloud-Anforderung von C #/Asp.net.
Bitte beachten Sie, dass Ihre Kundenseite das gleiche Thema haben sollte.
z.B.

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;

Versuchen Sie, ein Json-Objekt zu senden. Ersetzen Sie das:

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() + "&registration_id=" + deviceId + "";
        Console.WriteLine(postData);
        Byte[] byteArray = Encoding.UTF8.GetBytes(postData);

Dafür:

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);

Ich schreibe diesen Code und es hat für mich funktioniert.

public static string ExcutePushNotification(string title, string msg, string fcmToken, object data) 
{

        var serverKey = "AAAA*******************";
        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()))
        {
            result = streamReader.ReadToEnd();
        }
        return result;
}

Ich benutze diesen Ansatz und es funktioniert gut:

 public class PushNotification
 {
     private static readonly ILog Logger = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
        // firebase
     private static Uri FireBasePushNotificationsURL = new Uri("https://fcm.googleapis.com/fcm/send");
     private static string ServerKey = ConfigurationManager.AppSettings["FIREBASESERVERKEY"];

     public static async Task<bool> SendPushNotification(List<SendNotificationModel> notificationData)
     {
         try
         {
             bool sent = false;         
             foreach (var data in notificationData)
             {
                 var messageInformation = new Message()
                 {
                     notification = new Notification()
                     {
                         title = data.Title,
                         text = data.Message,
                         ClickAction = "FCM_PLUGIN_ACTIVITY"
                      },
                      data = data.data,
                      priority="high",
                      to =data.DeviceId
                 };
                 string jsonMessage = JsonConvert.SerializeObject(messageInformation);

                 //Create request to Firebase API
                 var request = new HttpRequestMessage(HttpMethod.Post, FireBasePushNotificationsURL);

                 request.Headers.TryAddWithoutValidation("Authorization", "key=" + ServerKey);
                 request.Content = new StringContent(jsonMessage, Encoding.UTF8, "application/json");

                 HttpResponseMessage result;
                 using (var client = new HttpClient())
                 {
                     result = await client.SendAsync(request);
                     sent =  result.IsSuccessStatusCode;
                 }             
             }

                return sent;
         }
         catch(Exception ex)
         {
             Logger.Error(ex);
             return false;
          }
    }
 }
