[C#] send firebase notification

firebase 를 이용해 token 기준으로 notification 을 보내는 방법입니다.

 

 

private void SendNotification()         {             try             {                 string url = @"https://fcm.googleapis.com/fcm/send";                 WebRequest tRequest = WebRequest.Create(url);                 tRequest.Method = "post";                 tRequest.ContentType = "application/json";                   // 디바이스 하나                 //string deviceId = "device1-token";                 //var data = new                 //{                 //    to = deviceId,                 //    notification = new                 //    {                 //        body = "This is the message",                 //        title = "This is the title"                   //    }                 //};                   // 디바이스 여러개                 List<string> diviceList = new List<string>() {                     "device1-token", "device2-token"                 };                   var data = new                 {                     registration_ids = diviceList,                     notification = new                     {                         body = "This is the message",                         title = "This is the title"                       }                 };                   string jsonss = Newtonsoft.Json.JsonConvert.SerializeObject(data);                   Byte[] byteArray = Encoding.UTF8.GetBytes(jsonss);                 tRequest.Headers.Add(string.Format("Authorization: key={0}", ServerKey]));                 tRequest.Headers.Add(string.Format("Sender: id={0}", 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 sResponseFromServer = tReader.ReadToEnd();                                 Console.Write(sResponseFromServer);                             }                         }                     }                 }             }

 

firebase 의 프로젝트 설정의 클라우드 메시징에 ServerKey, SenderID 정보가 있고 이값을 넣어주면 됩니다.
