Hi Lane,
I looked at the code which through which the error is propagating and i think
QueryAuthToken(NetworkCredentails) throws this GDataRequestException. The
problem is that the there is no response stream available when this error
occurs.
Should i log the PostData which is being sent for getting the AuthToken ? See
the code below, the highligted bold text is where the error is and the
responseString property of GDataRequestException returns null.
How do i track the error ? I am completely lost
protected string QueryAuthToken(NetworkCredential nc)
{
Tracing.Assert(nc != null, "Do not call QueryAuthToken with no network
credentials");
if (nc == null)
{
throw new System.ArgumentNullException("nc", "No credentials supplied");
}
// Create a new request to the authentication URL.
Uri authHandler = null;
try
{
authHandler = new Uri(this.factory.Handler);
}
catch
{
throw new GDataRequestException("Invalid authentication handler URI given");
}
WebRequest authRequest = WebRequest.Create(authHandler);
string accountType = GoogleAuthentication.AccountType;
if (this.factory.AccountType != null)
{
accountType += this.factory.AccountType;
}
else
{
accountType += GoogleAuthentication.AccountTypeDefault;
}
if (this.factory.Proxy != null)
{
authRequest.Proxy = this.factory.Proxy;
}
HttpWebRequest web = authRequest as HttpWebRequest;
if (web != null)
{
web.KeepAlive = this.factory.KeepAlive;
}
WebResponse authResponse = null;
string authToken = null;
try
{
authRequest.ContentType = HttpFormPost.Encoding;
authRequest.Method = HttpMethods.Post;
ASCIIEncoding encoder = new ASCIIEncoding();
// now enter the data in the stream
string postData = GoogleAuthentication.Email + "=" +
Utilities.UriEncodeReserved(nc.UserName) + "&";
postData += GoogleAuthentication.Password + "=" +
Utilities.UriEncodeReserved(nc.Password) + "&";
postData += GoogleAuthentication.Source + "=" +
Utilities.UriEncodeReserved(this.factory.ApplicationName) + "&";
postData += GoogleAuthentication.Service + "=" +
Utilities.UriEncodeReserved(this.factory.Service) + "&";
if (this.factory.CaptchaAnswer != null)
{
postData += GoogleAuthentication.CaptchaAnswer + "=" +
Utilities.UriEncodeReserved(this.factory.CaptchaAnswer) + "&";
}
if (this.factory.CaptchaToken != null)
{
postData += GoogleAuthentication.CaptchaToken + "=" +
Utilities.UriEncodeReserved(this.factory.CaptchaToken) + "&";
}
postData += accountType;
byte[] encodedData = encoder.GetBytes(postData);
authRequest.ContentLength = encodedData.Length;
Stream requestStream = authRequest.GetRequestStream() ;
requestStream.Write(encodedData, 0, encodedData.Length);
requestStream.Close();
authResponse = authRequest.GetResponse();
}
catch (WebException e)
{
Tracing.TraceMsg("QueryAuthtoken failed " + e.Status + " " + e.Message);
authResponse = e.Response;
}
HttpWebResponse response = authResponse as HttpWebResponse;
if (response != null)
{
// check the content type, it must be text
if (!response.ContentType.StartsWith(HttpFormPost.ReturnContentType))
{
throw new GDataRequestException("Execution of authentication request returned
unexpected content type: " + response.ContentType, this.Response);
}
// verify the content length. This should not be big, hence a big result might
indicate a phoney
if (response.ContentLength > 1024)
{
throw new GDataRequestException("Execution of authentication request returned
unexpected large content length: " + response.ContentLength, this.Response);
}
TokenCollection tokens =
Utilities.ParseStreamInTokenCollection(response.GetResponseStream());
authToken = Utilities.FindToken(tokens, GoogleAuthentication.AuthToken);
if (authToken == null)
{
throw getAuthException(tokens);
}
// failsafe. if getAuthException did not catch an error...
int code= (int)response.StatusCode;
if (code != 200)
{
throw new GDataRequestException("Execution of authentication request returned
unexpected result: " +code, this.Response);
}
}
Tracing.Assert(authToken != null, "did not find an auth token in
QueryAuthToken");
if (authResponse != null)
{
authResponse.Close();
}
return authToken;
}

Hi Kulvinder,
In Fidder the Session Inspector will allow you to view the network
traffic. Look at the 'Raw' view and see if you can find the packet
that is causing the error. Then post the request and response that
caused the problem -- be sure not to post and private data!
BTW - Did you try the workaround I posted?
Cheers,
Lane
