Hi,
The following code works fine on a Windows Server:
private string Authenticate()
{
//Create a web request for the Google ClientLogin service
HttpWebRequest authRequest =
(HttpWebRequest)HttpWebRequest.Create("https://www.google.com/accounts/ClientLogin
");
authRequest.KeepAlive = false;
authRequest.ContentType = "application/x-www-form-urlencoded";
authRequest.Method = "POST";
authRequest.AllowWriteStreamBuffering = false;
//Build the POST data
StringBuilder postBuilder = new StringBuilder();
postBuilder.AppendFormat("accountType={0}", GOOGLE_ACCOUNT_TYPE);
postBuilder.AppendFormat("&Email={0}", GOOGLE_USERNAME);
postBuilder.AppendFormat("&Passwd={0}", GOOGLE_PASSWORD);
postBuilder.AppendFormat("&service={0}", GOOGLE_SERVICE);
postBuilder.AppendFormat("&source={0}", GOOGLE_SOURCE);
//Convert the POST data to a byte[]
byte[] data = ASCIIEncoding.ASCII.GetBytes(postBuilder.ToString());
authRequest.ContentLength = data.Length;
//Get the request stream and POST the data
Stream requestStream = authRequest.GetRequestStream();
requestStream.Write(data, 0, data.Length);
requestStream.Close();
//Get the response
HttpWebResponse authResponse =
(HttpWebResponse)authRequest.GetResponse();
Stream responseStream = authResponse.GetResponseStream();
StreamReader responseReader = new StreamReader(responseStream);
string response = responseReader.ReadToEnd();
responseStream.Close();
if (response.Contains("Auth"))
{
int index = response.LastIndexOf("=") + 1;
string auth = response.Substring(index, response.Length -
index);
return auth;
}
else
{
throw new Exception(response);
}
}
On Linux/Mono 1.9 however, it throws an exception:
System.Net.ProtocolViolationException: Content-Length not set at
System.Net.HttpWebRequest.CommonChecks (Boolean putpost) [0x0008d] in /
usr/src/mono1.9-final/mono-1.9/mcs/class/System/System.Net/

www-data-temp-aspnet-0/b9f31429/App_Web_4abb242d_4.cs:234
I've checked the ContentLength and data.Length values, they are both
equal.
Any ideas?
Timothy.
