android - 未能在 android 和 .NET 中使用 google GCM

Question

我尝试在我的 asp.net 和 android 项目中使用 GCM。

大约需要 3 天，没有任何变化。

我的代码有什么问题？我真的很困惑...

安卓端：onCreate

 static final String GOOGLE_SENDER_ID = "tokyo-hghgf93712";  

        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_register);

            final String regIde = GCMRegistrar.getRegistrationId(this);
            if (regIde.equals("")) {
                GCMRegistrar.register(this, GOOGLE_SENDER_ID);
                Log.v(regIde, "Done!");
            } else {
                Log.v(regIde, "Already registered");
            }
    .....

asp.net 我的很多功能

功能一：

 public void SendCommandToPhone(String sCommand)
{
    String DeviceID = ";

     // DeviceID = "THE DEVICE ID YOU ARE SENDING TO";

WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send");
tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded";
tRequest.Headers.Add(string.Format("Authorization: key={0}", "tokyo-hghgf93712"));

String collaspeKey = Guid.NewGuid().ToString("n");
//String postData=string.Format("registration_id={0}&data.payload={1}&collapse_key={2}", DeviceID, "Pickup Message", collaspeKey);
String postData = string.Format("registration_id={0}&data.payload={1}&collapse_key={2}", DeviceID, sCommand, collaspeKey);

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();

tReader.Close();
dataStream.Close();
tResponse.Close();

}

功能二：

protected void Page_Load(object sender, EventArgs e)
          {
              if (IsPostBack)
              {
                  string BrowserAPIKey = "AIzaSygfdgdfgdfgfdgdfpjxgcw";

                  string message = "monaaaaaaa";
                  string tickerText = "test";
                  string contentTitle = "title";
                  string postData = "{ \"registration_ids\": [ \"" + tbRegistrationID.Text + "\" ], \"data\": {\"tickerText\":\"" + tickerText + "\", \"contentTitle\":\"" + contentTitle + "\", \"message\": \"" + message + "\"}}";

                  string response = SendGCMNotification(BrowserAPIKey, postData);

                  litResult.Text = response;
              }
          }


          /// <summary>
          /// Send a Google Cloud Message. Uses the GCM service and your provided api key.

          private string SendGCMNotification(string apiKey, string postData, string postDataContentType = "application/json")
          {

              Request.KeepAlive = false;
              Request.ContentType = postDataContentType;
              Request.Headers.Add(string.Format("Authorization: key={0}", apiKey));
              Request.ContentLength = byteArray.Length;
              // Request.Headers.Add(string.Format("Sender: id={0}", "5637737476457"));
              //  Request.Headers.Add(string.Format("Authorization: key={0}", "5637737476457"));

              Stream dataStream = Request.GetRequestStream();
              dataStream.Write(byteArray, 0, byteArray.Length);
              dataStream.Close();

              //
              //  SEND MESSAGE
              try
              {
                  WebResponse Response = Request.GetResponse();
                  HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode;
                  if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden))
                  {
                      var text = "Unauthorized - need new token";

                  }
                  else if (!ResponseCode.Equals(HttpStatusCode.OK))
                  {
                      var text = "Response from web service isn't OK";
                  }

                  StreamReader Reader = new StreamReader(Response.GetResponseStream());
                  string responseLine = Reader.ReadToEnd();
                  Reader.Close();

                  return responseLine;
              }
              catch (Exception e)
              {

              }
              return "error";
          }


          public static bool ValidateServerCertificate(
                                                    object sender,

              return true;


 }
