Blackberry Push Service Initiator sur IIS/.NET

Question

Je dois envoyer des notifications push à un périphérique Blackberry à partir de mon application ASP.NET. Quelle est la meilleure façon de le faire? Y a-t-il des bibliothèques .NET? Ai-je besoin de compiler une demande PAP par moi-même ou quelque chose comme ça?

Answer 1

Il existe désormais un SDK C# BlackBerry Push open-source pouvant être utilisé et consommé par une application ASP.NET.

Le projet est hébergé sur CodePlex here.

Si vous ne voulez pas mettre en œuvre une bibliothèque 3ème partie, ce code a bien fonctionné pour moi:

private static string UrlForPush = "https://cp815.pushapi.na.blackberry.com"; 
private static string ApplicationId = "your_appid"; 
private static string Password = "your_password"; 

// NOTE: deviceToken below is the BB PIN unique to each device. 

public static string SendPushNotification(string deviceToken, string message) 
{ 
    try 
    { 
     var myPushId = DateTime.Now.ToFileTime().ToString(); 
     var deliverBefore = DateTime.UtcNow.AddMinutes(5).ToString("s", CultureInfo.InvariantCulture) + "Z"; 
     var boundary = "CiTySoUrCeDbLaCkBeRrY"; 
     var url = UrlForPush + "/mss/PD_pushRequest"; 

     var data = new StringBuilder(); 
     data.AppendLine("--" + boundary); 
     data.AppendLine("Content-Type: application/xml; charset=UTF-8"); 
     data.AppendLine(""); 
     data.AppendLine("<?xml version=\"1.0\"?>"); 
     data.AppendLine("<!DOCTYPE pap PUBLIC \"-//WAPFORUM//DTD PAP 2.1//EN\" \"http://www.openmobilealliance.org/tech/DTD/pap_2.1.dtd\">"); 
     data.AppendLine("<pap>"); 
     data.AppendLine("<push-message push-id=\"" + myPushId + "\" deliver-before-timestamp=\"" + deliverBefore + "\" source-reference=\"" + ApplicationId + "\">"); 
     data.AppendLine("<address address-value=\"" + deviceToken + "\"/>"); 
     data.AppendLine("<quality-of-service delivery-method=\"unconfirmed\"/>"); 
     data.AppendLine("</push-message>"); 
     data.AppendLine("</pap>"); 
     data.AppendLine("--" + boundary); 
     data.AppendLine("Content-Type: text/plain"); 
     data.AppendLine("Push-Message-ID: " + myPushId); 
     data.AppendLine(""); 
     data.AppendLine(message); 
     data.AppendLine("--" + boundary + "--"); 
     data.AppendLine(""); 

     // Create the Request... 
     var request = (HttpWebRequest)WebRequest.Create(url); 
     request.Method = ("POST"); 
     request.Accept = "text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2"; 
     request.Credentials = new NetworkCredential(ApplicationId, Password); 
     request.PreAuthenticate = true; 
     request.ContentType = "multipart/related; boundary=" + boundary + "; type=application/xml"; 
     SetBasicAuthHeader(request, ApplicationId, Password); 
     var bytes = new ASCIIEncoding().GetBytes(data.ToString()); 
     request.ContentLength = bytes.Length; 

     // Write Stream... 
     using (var stream = request.GetRequestStream()) 
     { 
      stream.Write(bytes, 0, bytes.Length); 
     } 

     // Get Response ... 
     var responseAsString = string.Format("Push ID: {0}", myPushId) + Environment.NewLine + Environment.NewLine; 
     using (var response = request.GetResponse() as HttpWebResponse) 
     { 
      var reader = new StreamReader(response.GetResponseStream()); 
      responseAsString += reader.ReadToEnd(); 
      reader.Close(); 
     } 

     // Return... 
     return responseAsString; 
    } 
    catch (Exception ex) 
    { 
     return ex.Message; 
    } 
} 
private static void SetBasicAuthHeader(WebRequest webRequest, String userName, String password) 
{ 
    var authInfo = userName + ":" + password; 
    authInfo = Convert.ToBase64String(Encoding.Default.GetBytes(authInfo)); 
    webRequest.Headers["Authorization"] = "Basic " + authInfo; 
}
