我有一个带有ASP.NET后端的Android应用程序.我有手机的registration_id以及来自谷歌的执行推送的应用服务器的身份验证令牌.
当我向C2DM发出http post请求以便手机收到消息时,我一直收到401 Unauthorized.以下是我在.NET中发出请求的方式：
WebRequest myRequest = WebRequest.Create("https://android.apis.google.com/c2dm/send");
myRequest.ContentType = "application/x-www-form-urlencoded";
myRequest.Method = "POST";
myRequest.Headers.Add("Authorization","GoogleLogin auth=" + authId);
// buiold the post string
StringBuilder myPost = new StringBuilder();
myPost.AppendFormat("registration_id={0}",regId);
myPost.AppendFormat("&data.payload={0}",msg);
myPost.AppendFormat("&collapse_key={0}",colKey);
// write the post-string as a byte array
byte[] myData = ASCIIEncoding.ASCII.GetBytes(myPost.ToString());
myRequest.ContentLength = myData.Length;
Stream myStream = myRequest.GetRequestStream();
myStream.Write(myData,myData.Length);
myStream.Close();
// Do the actual request and read the response stream
WebResponse myResponse = myRequest.GetResponse();
Stream myResponseStream = myResponse.GetResponseStream();
StreamReader myResponseReader = new StreamReader(myResponseStream);
string strResponse = myResponseReader.ReadToEnd();
myResponseReader.Close();
myResponseStream.Close();
任何帮助将非常感激.
