廢話不多說付上程式碼

public static void SendPushNotification()
        {

            try
            {
                //伺服器
                string applicationID = "FCM伺服器金鑰";

                string senderId = "FCM寄件者 ID";

                //string deviceId = "手機的TOKEN";
                string deviceId = "/topics/Test";

                
                 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 = "Osama",
                        title = "AlBaami",
                        sound = "Enabled"

                    }
                };
                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;
            }
        }

在這邊要說明一下 deviceID 就是字面上的意思，裝置的ID也就是裝置的TOKEN，你必須先去上一篇製作一個APP，放入你要推播的手機內，

便會alert該手機的TOKEN  這樣可以達到單人的推播

如果要多人以上

就要使用string deviceid = "/Topics/Test" 這個

但前提你要先將你的APP中加上

即可
