使用FCM与Asp.net web api 2

Question

我已经构建了一个web api,它将成为AngularJs,IOS和Android前端应用程序的后端.

现在我需要在例如产品更新时将通知从我的web api推送到前端应用程序.

我正在考虑使用SignalR以实时方式推送通知,但如果其他用户处于脱机状态则无用.

现在我打算使用FCM推送通知,所以你可以请你回答我的问题

如何将我的web api与FCM集成,以及在推送通知时使用FCM可以获得哪些好处？

PS

我将不胜感激任何将asp.net web api与FCM集成的参考资料

让我们创建控制台应用程序如下:

    class Program
{
    static void Main(string[] args)
    {
        string resend ;
        do
        {
            WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");
            tRequest.Method = "post";
            tRequest.ContentType = "application/json";
            var objNotification = new
            {
                to = "Token the device you want to push notification to",
                data = new
                {
                    title = "title",
                    body = "body",
                    icon = "/firebase-logo.png"
                }
            };
            string jsonNotificationFormat = Newtonsoft.Json.JsonConvert.SerializeObject(objNotification);

            Byte[] byteArray = Encoding.UTF8.GetBytes(jsonNotificationFormat);
            tRequest.Headers.Add(string.Format("Authorization: key={0}", "your authorization key"));
            tRequest.Headers.Add(string.Format("Sender: id={0}", "your senderId"));
            tRequest.ContentLength = byteArray.Length;
            tRequest.ContentType = "application/json";
            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 responseFromFirebaseServer = tReader.ReadToEnd();

                            FCMResponse response = Newtonsoft.Json.JsonConvert.DeserializeObject<FCMResponse>(responseFromFirebaseServer);
                            if (response.success == 1)
                            {

                                Console.WriteLine("succeeded");
                            }
                            else if (response.failure == 1)
                            {
                               Console.WriteLine("failed");

                            }

                        }
                    }

                }
            }

            resend = Console.ReadLine();
        } while (resend == "c");
    }

}

public class FCMResponse
{
    public long multicast_id { get; set; }
    public int success { get; set; }
    public int failure { get; set; }
    public int canonical_ids { get; set; }
    public List<FCMResult> results { get; set; }
}
public class FCMResult
{
    public string message_id { get; set; }
}
