c2dm を使用して userId や eventId などのサーバー側からエクストラを送信し、onMessage() 関数で Android アプリケーションから取得する方法は?
これは、サーバー側関数 C# の SendMessage です。
private static void SendMessage(string authTokenString, string registrationId, string message)
{
//Certeficate was not being accepted for the sercure call
//ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(GoogleMessageUrl);
request.Method = PostWebRequest;
request.KeepAlive = false;
NameValueCollection postFieldNameValue = new NameValueCollection();
postFieldNameValue.Add(RegistrationIdParam, registrationId);
postFieldNameValue.Add(CollapseKeyParam, "0");
postFieldNameValue.Add(DelayWhileIdleParam, "0");
postFieldNameValue.Add(DataPayloadParam, message);
string postData = GetPostStringFrom(postFieldNameValue);
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
request.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
request.ContentLength = byteArray.Length;
request.Headers.Add(HttpRequestHeader.Authorization, "GoogleLogin auth=" + authTokenString);
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse response = request.GetResponse();
HttpStatusCode responseCode = ((HttpWebResponse)response).StatusCode;
if (responseCode.Equals(HttpStatusCode.Unauthorized) || responseCode.Equals(HttpStatusCode.Forbidden))
{
Console.WriteLine("Unauthorized - need new token");
}
else if (!responseCode.Equals(HttpStatusCode.OK))
{
Console.WriteLine("Response from web service not OK :");
Console.WriteLine(((HttpWebResponse)response).StatusDescription);
}
StreamReader reader = new StreamReader(response.GetResponseStream());
string responseLine = reader.ReadLine();
reader.Close();
}
