I am trying to send a Push Message to my BlackBerry App. The BlackBerry successfully receives the message via the php server side code. However I am struggling with the c# server side code for quite sometime now. Following is the code that I am running:
string userName = "<appID>";
string userPW = "<password>";
public static void SetBasicAuthHeader(WebRequest req, String userName, String userPassword)
{
string authInfo = userName + ":" + userPassword;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
req.Headers["Authorization"] = "Basic " + authInfo;
}
public static void SetProxy(WebRequest req)
{
Uri newUri = new Uri("http://cp(AppID).pushapi.eval.blackberry.com");
WebProxy proxy = new WebProxy();
proxy.Address = newUri;
proxy.Credentials = new NetworkCredential("<appID>", "<password>");
req.Proxy = proxy;
}
public bool pushTest(string msg)
{
HttpWebResponse HttpWRes = null;
HttpWebRequest HttpWReq = null;
string pin = "xxxxxxxx"; // or actual pin of device
string applicationID = "xxxxxxxxxxxxxxxxxxxxxx";
string BOUNDARY = "mPsbVQo0a68eIL3OAxnm";
//string msg1 = "testing c#"; // the message to send
string userName = "<appID>";
string userPW = "<password>";
string url = "https://pushapi.eval.blackberry.com/mss/PD_pushRequest";
HttpWReq = (HttpWebRequest)WebRequest.Create(url);
SetProxy(HttpWReq);
HttpWReq.Method = ("POST");
HttpWReq.Accept = "text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2";
//HttpWReq.Credentials = new NetworkCredential(userName, userPW);
HttpWReq.PreAuthenticate = true;
HttpWReq.ContentType = "multipart/related; boundary=" + BOUNDARY + "; type=application/xml";
SetBasicAuthHeader(HttpWReq, userName, userPW);
StringBuilder dataToSend = new StringBuilder();
dataToSend.AppendLine("--" + BOUNDARY);
dataToSend.AppendLine("Content-Type: application/xml; charset=UTF-8");
dataToSend.AppendLine("");
dataToSend.AppendLine("<?xml version=\"1.0\"?>");
dataToSend.AppendLine("<!DOCTYPE pap PUBLIC \"-//WAPFORUM//DTD PAP 2.1//EN\" \"http://www.openmobilealliance.org/tech/DTD/pap_2.1.dtd\">");
dataToSend.AppendLine("<pap>");
string myPushId = DateTime.Now.ToFileTime().ToString();
dataToSend.AppendLine("<push-message push-id=\"" + myPushId + "\" source-reference=\"" + applicationID + "\">");
dataToSend.AppendLine("<address address-value=\"" + pin + "\"/>");
dataToSend.AppendLine("<quality-of-service delivery-method=\"unconfirmed\"/>");
dataToSend.AppendLine("</push-message>");
dataToSend.AppendLine("</pap>");
dataToSend.AppendLine("--" + BOUNDARY);
dataToSend.AppendLine("Content-Type: text/plain");
dataToSend.AppendLine("Push-Message-ID: " + myPushId);
dataToSend.AppendLine("");
dataToSend.AppendLine(msg);
dataToSend.AppendLine("--" + BOUNDARY + "--");
dataToSend.AppendLine("");
Stream requestStream = null;
string pushResult = "";
try
{
requestStream = HttpWReq.GetRequestStream();
}
catch (Exception ex)
{
pushResult = "Push failed! " + ex.ToString();
}
byte[] outStr = new ASCIIEncoding().GetBytes(dataToSend.ToString());
requestStream.Write(outStr, 0, outStr.Length);
requestStream.Close();
try
{
HttpWRes = (HttpWebResponse)HttpWReq.GetResponse();
// MessageBox.show(""+HttpWRes);
}
catch (Exception ex)
{
//push failed
}
if (HttpWRes != null)
{
HttpWRes.Close();
}
return true;
}
I get the following error:
Push failed! System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 68.171.224.60:80

--- End of inner exception stack trace ---
at System.Net.HttpWebRequest.GetRequestStream(TransportContext& context)
at System.Net.HttpWebRequest.GetRequestStream()
Is there any issue with the credentials applied?or the URL? Please help!!
I managed to solve the issue. The main issue in the above code was structuring the Http request.
WebRequest tRequest;
tRequest = WebRequest.Create(httpURL);
tRequest.Method = "POST";
tRequest.Credentials = new NetworkCredential(appid, password);
Another important thing to handle is the Http Response 401 that occurs when making the request through the NetworkCredentials as mentioned above. To handle this, the following method should be called while making the request:
public static void SetBasicAuthHeader(WebRequest req, String appID, String userPassword)
{
string authInfo = appID + ":" + userPassword;
authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo));
req.Headers["Authorization"] = "Basic " + authInfo;
}
The complete server side code for Push Message is as follows:
private void pushMessageSample(string pushedMessage)
{
String appid="xxxx-xxxxxxxxxxxxxxxxxxxxxxxxxx";
String password = "xxxxxx";
String deliverbefore = DateTime.UtcNow.AddMinutes(5).ToString("s",System.Globalization.CultureInfo.InvariantCulture) + "Z";
String pushPin = "xxxxxxxx";
String Boundary = "mPsbVQo0a68eIL3OAxnm";
StringBuilder dataToSend = new StringBuilder();
dataToSend.AppendLine("--" + Boundary);
dataToSend.AppendLine("Content-Type: application/xml; charset=UTF-8");
dataToSend.AppendLine("");
dataToSend.AppendLine("<?xml version=\"1.0\"?>");
dataToSend.AppendLine("<!DOCTYPE pap PUBLIC \"-//WAPFORUM//DTD PAP 2.1//EN\" \"http://www.openmobilealliance.org/tech/DTD/pap_2.1.dtd\">");
dataToSend.AppendLine("<pap>");
string myPushId = DateTime.Now.ToFileTime().ToString();
dataToSend.AppendLine("<push-message push-id=" + (char)34 + myPushId + (char)34 + " deliver-before-timestamp=" +
(char)34 + deliverbefore + (char)34 + " source-reference=" + (char)34 + appid + (char)34 + ">");
//dataToSend.AppendLine("<push-message push-id=\"" + myPushId + "\" source-reference=\"" + appid + "\">");
dataToSend.AppendLine("<address address-value=\"" + pushPin + "\"/>");
dataToSend.AppendLine("<quality-of-service delivery-method=\"unconfirmed\"/>");
dataToSend.AppendLine("</push-message>");
dataToSend.AppendLine("</pap>");
dataToSend.AppendLine("--" + Boundary);
dataToSend.AppendLine("Content-Type: text/plain");
dataToSend.AppendLine("Push-Message-ID: " + myPushId);
dataToSend.AppendLine("");
dataToSend.AppendLine(pushedMessage);
dataToSend.AppendLine("--" + Boundary + "--");
dataToSend.AppendLine("");
byte[] bytes = Encoding.ASCII.GetBytes(dataToSend.ToString());
String httpURL = "https://cpxxxx.pushapi.eval.blackberry.com/mss/PD_pushRequest";
WebRequest tRequest;
tRequest = WebRequest.Create(httpURL);
tRequest.Method = "POST";
tRequest.Credentials = new NetworkCredential(appid, password);
tRequest.PreAuthenticate = true;
tRequest.ContentType = "multipart/related; boundary=" + Boundary + "; type=application/xml";
tRequest.ContentLength = bytes.Length;
string rawCredentials = string.Format("{0}:{1}", appid, password);
tRequest.Headers.Add("Authorization",string.Format("Basic {0}",
Convert.ToBase64String(Encoding.UTF8.GetBytes(rawCredentials))));
SetBasicAuthHeader(tRequest, appid, password);
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(bytes, 0, bytes.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
String sResponseFromServer = tReader.ReadToEnd();
tReader.Close();
dataStream.Close();
tResponse.Close();
