I have following code which give "Error:MissingRegistration" response from GCM server.
public void SendPushNotification()
{
string stringregIds = null;
List<string> regIDs = _db.Directories.Where(i => i.GCM != null && i.GCM != "").Select(i => i.GCM).ToList();
//Here I add the registrationID that I used in Method #1 to regIDs
stringregIds = string.Join("\",\"", regIDs);
//To Join the values (if ever there are more than 1) with quotes and commas for the Json format below
try
{
string GoogleAppID = "AIzaSyA2Wkdnp__rBokCmyloMFfENchJQb59tX8";
var SENDER_ID = "925760665756";
var value = "Hello";
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
Request.ContentType = "application/json";
tRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
string postData = "{\"collapse_key\":\"score_update\",\"time_to_live\":108,\"delay_while_idle\":true,\"data\": { \"message\" : " + "\"" + value + "\",\"time\": " + "\"" + System.DateTime.Now.ToString() + "\"},\"registration_ids\":[\"" + stringregIds + "\"]}";
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();
TempData["msg1"] = "<script>alert('" + sResponseFromServer + "');</script>";
HttpWebResponse httpResponse = (HttpWebResponse)tResponse;
string statusCode = httpResponse.StatusCode.ToString();
tReader.Close();
dataStream.Close();
tResponse.Close();
}
catch (Exception ex)
{
}
}
But exact string returned by 'postData' posted by Postman or Fiddler gives positive response and notification arrived at device.
What I'm missing in my code please help me.
The postData returns this value which successfully posted by Postman And Fiddler
{"collapse_key":"score_update","time_to_live":108,"delay_while_idle":true,"data": { "message" : "Hello","time": "5/13/2016 5:50:59 PM"},"registration_ids":["cXMf6hkYIrw:APA91bGr-8y2Gy-qzNJ3zjrlf8t-4m9uDib9P0j8GW87bH5jq891-x_7P0qqItzlc_HXh11Arg76lCOcjXPrU9LAgtYLwllH2ySxA0ADSfiz3qPolajjvI3d3zE6Rh77dwRqXn3NnbAm"]}
The problem in your code is in ContentType
Instead of using this:-
Request.ContentType = "application/json";
Use
tRequest.ContentType = "application/json";
It will work
Try This:-
private string SendGCMNotification()
{
try
{
string message = "some test message";
//string tickerText = "example test GCM";
string contentTitle = "content title GCM";
string registration_id = "cXMf6hkYIrw:APA91bGr-8y2Gy-qzNJ3zjrlf8t-4m9uDib9P0j8GW87bH5jq891-x_7P0qqItzlc_HXh11Arg76lCOcjXPrU9LAgtYLwllH2ySxA0ADSfiz3qPolajjvI3d3zE6Rh77dwRqXn3NnbAm";
string postData =
"{ \"registration_ids\": [ \"" + registration_id + "\" ], " +
"\"data\": {\"contentTitle\":\"" + contentTitle + "\", " +
"\"message\": \"" + message + "\"}}";
string GoogleAppID = "AIzaSyA2Wkdnp__rBokCmyloMFfENchJQb59tX8";
WebRequest wRequest;
wRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
wRequest.Method = "POST";
wRequest.ContentType = " application/json;charset=UTF-8";
wRequest.Headers.Add(string.Format("Authorization: key={0}", GoogleAppID));
var bytes = Encoding.UTF8.GetBytes(postData);
wRequest.ContentLength = bytes.Length;
var stream = wRequest.GetRequestStream();
stream.Write(bytes, 0, bytes.Length);
stream.Close();
var wResponse = wRequest.GetResponse();
stream = wResponse.GetResponseStream();
var reader = new StreamReader(stream);
var response = reader.ReadToEnd();
var httpResponse = (HttpWebResponse)wResponse;
var status = httpResponse.StatusCode.ToString();
reader.Close();
stream.Close();
wResponse.Close();
//TODO check status
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
return "sent";
}

I am using GCM for notifications on Android with c#, but now I want to change GCM to FCM.
What do I have to change for that? Or how can I implement FCM in C#? Any help is appreciated. I am currently using this code for FCM, I just changed URL but it's not working.
try {
msg = message;
var applicationID = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
var SENDER_ID = "xxxxxxxxxxx";

It looks like you are sending the wrong authorization key here:
tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID));
You will need to change applicationID here to your API key, which you assigned to GOOGLE_API_KEY.
Lastly, you may want to consider hiding your actual API key from this StackOverflow post.
I'm trying to figure out how to post a new task to a user in asana, but I keep getting the 400 error code. Can anyone tell me what I am doing wrong.
This is what I have so far:
string apiKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string ID = "xxxxxxxxxxxxx";
string url = #"https://app.asana.com/api/1.0/tasks";
Data dat = new Data();
dat.workspace = ID;
dat.name = "Buy eggs";
dat.notes = "Testing";
string json = JsonConvert.SerializeObject(dat);
string data ="\"data\": " + json;
byte[] bytes = Encoding.UTF8.GetBytes(data);
var req = (HttpWebRequest)WebRequest.Create(url);
Console.WriteLine(bytes.ToString());
req.Method = WebRequestMethods.Http.Post;
req.ContentLength = bytes.Length;
req.ContentType = "application/json";
var authInfo = apiKey + ":";
var encodedAuthInfo = Convert.ToBase64String(
Encoding.Default.GetBytes(authInfo));
req.Headers.Add("Authorization", "Basic " + encodedAuthInfo);
req.ContentLength = bytes.Length;
Stream reqStream = req.GetRequestStream();
reqStream.Write(bytes, 0, bytes.Length);
reqStream.Close();
try
{
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
Console.WriteLine(res);
Console.ReadLine();
}
catch (WebException ex)
{
HttpWebResponse response = ((HttpWebResponse)ex.Response);
string e = url + " caused a " + (int)response.StatusCode + " error.\n" + response.StatusDescription;
Console.WriteLine(e);
Console.ReadLine();
}
I put the serial converter, did i do it wrong?
As the first comment points out, you need to serialize the data properly. The final body posted should look something like:
{ "data": { "name": "My Example Task", ... }}
(Except of course with the ... replaced with more fields.)
I have researched a long and found below code useful and working. I can successfully post Task to Asana through my application. I have used Json serializer for dot net. Thanks to Newtonsoft.Json.
string json = null;
byte[] bytes = null;
string url = "https://app.asana.com/api/1.0/tasks";
HttpWebRequest req = default(HttpWebRequest);
Stream reqStream = default(Stream);
string authInfo = null;
Task TaskData = new Task();
try
{
authInfo = apiKey + Convert.ToString(":");
TaskData.workspace = WorkspaceId;
TaskData.name = TaskName;
TaskData.notes = TaskNotes;
json = JsonConvert.SerializeObject(TaskData);
json = json.Insert((json.Length - 1), ",\"projects\":[" + ProjectId + "]");
json = Convert.ToString("{ \"data\":") + json + "}";
bytes = Encoding.UTF8.GetBytes(json);
req = (HttpWebRequest)WebRequest.Create(url);
req.Method = WebRequestMethods.Http.Post;
req.ContentType = "application/json";
req.Headers.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)));
req.ContentLength = bytes.Length;
reqStream = req.GetRequestStream();
reqStream.Write(bytes, 0, bytes.Length);
reqStream.Close();
HttpWebResponse response = (HttpWebResponse)req.GetResponse();
string res = new StreamReader(response.GetResponseStream()).ReadToEnd();
Console.WriteLine(res);
Console.ReadLine();
string finalString = res.Remove(0, 8);
finalString = finalString.Remove((finalString.Length - 1));
AsanaObjectId newtask = JsonConvert.DeserializeObject<AsanaObjectId>(finalString);
return newtask;
}
catch (WebException ex)
{
HttpWebResponse response = (HttpWebResponse)ex.Response;
string resp = new StreamReader(ex.Response.GetResponseStream()).ReadToEnd();
MessageBox.Show(resp);
System.Environment.Exit(0);
}
My SOAP request works - hits the server and displays my request in the server logs and sends the response but I am unable to read the response with my codes (C# & ASP.NET) below.Am I missing something?
