使用Asp.net推送通知（GCM）（未收到通知）（浏览器密钥）

问题描述

我已经建立在谷歌云消息的应用（GCM）
他们给我：

I've Create An Application in Google Cloud Messaging (GCM)And they Give Me :

1. 发件人ID


2. API-KEY

1. SENDER-ID
2. API-KEY

我已经创建一个Android应用程序，客户可以用来注册他们的设备结果
云..（和它的确定）。

I've Create An Android Application that Clients Can Used To Register their Devices
to the cloud .. (And It's OK).

现在我要推休息设备的通知，如果任何用户使用数据我的Andr​​oid应用程序改变的东西（SQL Server数据库）。

Now I want to Push A notification to Rest Of Devices if Any User Using My Android Application Change Something in the data (SQL SERVER DATABASE) .

我发现这code ...

I found This Code ...

 private string SendGCMNotification(string apiKey, string postData, string postDataContentType = "application/json")
         {
             ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate);

             //
             //  MESSAGE CONTENT
             byte[] byteArray = Encoding.UTF8.GetBytes(postData);

             //
             //  CREATE REQUEST
             HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send");
             Request.Method = "POST";
             Request.KeepAlive = false;
             Request.ContentType = postDataContentType;
             Request.Headers.Add(string.Format("Authorization: key={0}", apiKey));
             Request.ContentLength = byteArray.Length;

             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,
                                                     X509Certificate certificate,
                                                     X509Chain chain,
                                                     SslPolicyErrors sslPolicyErrors)
         {
             return true;
         }

不过，当我需要执行的方法（它要求我给它浏览器APIKey 的参数）

    string deviceId = "APA91bHsQUsnYLHSFkmmJE8AgXEU--_nqPOJ5q2sfZIpCI1ZiJnmi2-IrZCqwummfJB94uVmqgT-ZWkyeIrICU8GpPvAOdmUfiVtYRmmA7bVAaKPuerJUcRUisveOe5Jp36-3fUK7VlDvwcme0SaJiwJU9B1y1EkF6YTQ00g";
    string message = "some test message";
    string tickerText = "example test GCM";
    string contentTitle = "content title GCM";
    string postData =
    "{ \"registration_ids\": [ \"" + deviceId + "\" ], " +
      "\"data\": {\"tickerText\":\"" + tickerText + "\", " +
                 "\"contentTitle\":\"" + contentTitle + "\", " +
                 "\"message\": \"" + message + "\"}}";

首先， - >请问这种方法将有助于我正确地发送推送通知？或者它可以提高到更好？

First Of All --> Does This Method Will Helps me to send a push notification correctly ?? or it can be improved to be better ?

如果是好...

这是我在哪里可以得到浏览器键 ??

from where can i get the Browser KEY ??

在此先感谢：）

推荐答案

您必须获得来自谷歌的API控制台您的浏览器的密钥。

You have to obtain your Browser-Key from Google APIs Console. https://code.google.com/apis/console

您Browserkey将是40个字节的大小。

Your Browserkey will be 40 bytes in size.
