Firebase 云消息传递的 C#服务器端代码

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Web;
using System.Web.Script.Serialization;

namespace Sch_WCFApplication
{
    public class PushNotification
    {
        public PushNotification(Plobj obj)
        {
            try
            {    
                var applicationID = "AIza---------4GcVJj4dI";

                var senderId = "57-------55";

                string deviceId = "euxqdp------ioIdL87abVL";

                WebRequest tRequest = WebRequest.Create("https://fcm.googleapis.com/fcm/send");

                tRequest.Method = "post";

                tRequest.ContentType = "application/json";

                var data = new

                {

                    to = deviceId,

                    notification = new

                    {

                        body = obj.Message,

                        title = obj.TagMsg,

                        icon = "myicon"

                    }    
                };       

                var serializer = new JavaScriptSerializer();

                var json = serializer.Serialize(data);

                Byte[] byteArray = Encoding.UTF8.GetBytes(json);

                tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));

                tRequest.Headers.Add(string.Format("Sender: id={0}", senderId));

                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;

                            }    
                        }    
                    }    
                }    
            }        

            catch (Exception ex)
            {

                string str = ex.Message;

            }          

        }   

    }
}

APIKey和senderId,你得到的是---------如下(图片下方)(转到你的firebase应用程序)

2019更新

有一个新的.NET Admin SDK，可让您从服务器发送通知。通过Nuget安装

Install-Package FirebaseAdmin

然后，您必须按照此处给出的说明进行下载，以获取服务帐户密钥，然后在您的项目中进行引用。我已经能够通过这样初始化客户端来发送消息

using FirebaseAdmin;
using FirebaseAdmin.Messaging;
using Google.Apis.Auth.OAuth2;
...

public class MobileMessagingClient : IMobileMessagingClient
{
    private readonly FirebaseMessaging messaging;

    public MobileMessagingClient()
    {
        var app = FirebaseApp.Create(new AppOptions() { Credential = GoogleCredential.FromFile("serviceAccountKey.json").CreateScoped("https://www.googleapis.com/auth/firebase.messaging")});           
        messaging = FirebaseMessaging.GetMessaging(app);
    }
    //...          
}

初始化应用程序后，您现在可以创建通知和数据消息，并将它们发送到所需的设备。

private Message CreateNotification(string title, string notificationBody, string token)
{    
    return new Message()
    {
        Token = token,
        Notification = new Notification()
        {
            Body = notificationBody,
            Title = title
        }
    };
}

public async Task SendNotification(string token, string title, string body)
{
    var result = await messaging.SendAsync(CreateNotification(title, body, token)); 
    //do something with result
}

.....然后可以在您的服务集中添加它...

services.AddSingleton<IMobileMessagingClient, MobileMessagingClient >();

 public class Notification
{
    private string serverKey = "kkkkk";
    private string senderId = "iiddddd";
    private string webAddr = "https://fcm.googleapis.com/fcm/send";

    public string SendNotification(string DeviceToken, string title ,string msg )
    {
        var result = "-1";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        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
        {
            to = DeviceToken,
            priority = "high",
            content_available = true,
            notification = new
            {
                body = msg,
                title = title
            },
        };
        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;
    }
}
