我已经创建了一个Android应用程序，即注册到谷歌C2DM服务。和它的成功正从C2DM服务registration_id令牌。

I have created an android app, that registering to google c2dm service. And It's getting a registration_id token from c2dm services successfully.

我已经签署了Android云端到设备消息的形式和我从C2DM服务收到确认电子邮件。

I already signed Android Cloud to Device Messaging form and I received confirmation email from c2dm service.

一切似乎都在客户端确定，它在仿真环境中得到registration_id。所以，它的确定。

Everything seems ok in client side, it's getting registration_id in simulator environment. So, it's ok.

不过，在服务器端，这是谷歌认证服务，它接收验证code，那么它的调用来C2DM与发送URL低于code。

But, On server side, It's authenticating google service, it's receiving Auth code then it's invoking to c2dm send url with below code.

  public void SendMessage(string registrationId, string data)
    {
        ServicePointManager.ServerCertificateValidationCallback += delegate(
                                            object sender,
                                            X509Certificate certificate,
                                            X509Chain chain,
                                            SslPolicyErrors sslPolicyErrors)
        {
            return true;
        };

        string collapseKey = Guid.NewGuid().ToString("n");          

        string url = "https://android.apis.google.com/c2dm/send";
        HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);
        request.Method = "POST";
        request.Headers.Add("Authorization", "GoogleLogin auth=DQAAAKYAAACE_0NqG8Sj5lBf4YSPXs_ltQbTzPsAL5u1Q1KGF...");

        string px = "registration_id=" + registrationId + "&collapse_key=" + collapseKey + "&data.payload=" + data;
        string encoded = HttpUtility.UrlEncode(px);

        ASCIIEncoding encoding = new ASCIIEncoding();
        byte[] buffer = encoding.GetBytes(encoded);

        Stream newStream = request.GetRequestStream();
        newStream.Write(buffer, 0, buffer.Length);
        newStream.Close();




         HttpWebResponse response = (HttpWebResponse)request.GetResponse();
         if(response.StatusCode == HttpStatusCode.OK)
         {
             Stream resStream = response.GetResponseStream();
             StreamReader sr = new StreamReader(resStream);
             Console.Write(sr.ReadToEnd());
             sr.Close();
             resStream.Close();
         }
         Console.WriteLine();
         Console.ReadLine();
    }

从C2DM服务

它仍然接收错误= InvalidRegistration 响应。

It's still receiving Error=InvalidRegistration response from c2dm service.

我在做什么错？

推荐答案

好吧，它解决了。我删除 HttpUtility.UrlEn code（PX）; 和一切工作如我所料

Ok, It solved. I removed HttpUtility.UrlEncode(px); and everything worked as I expected.
