I am trying to authenticate user through windows live account with following code.
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
WebRequest request = WebRequest.Create("https://oauth.live.com/token");
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = byteArray.Length;
request.Method = "POST";
Stream resp = request.GetRequestStream();
Stream dataStream = request.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
var response = request.GetResponse();
But I am getting following error at last line.
The remote server returned an error: (400) Bad Request.
what should I do for this?
Your issue is probably because we do not send bytes on "application/x-www-form-urlencoded" post but a string. Also the GetRespose is not looks like the correct one. Your code must be something like:
// I do not know how you create the byteArray
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// but you need to send a string
string strRequest = Encoding.ASCII.GetString(byteArray);
WebRequest request = WebRequest.Create("https://oauth.live.com/token");
request.ContentType = "application/x-www-form-urlencoded";
// not the byte length, but the string
//request.ContentLength = byteArray.Length;
request.ContentLength = strRequest.Length;
request.Method = "POST";
using (StreamWriter streamOut = new StreamWriter(request.GetRequestStream(), System.Text.Encoding.ASCII))
{
streamOut.Write(strRequest);
streamOut.Close();
}
string strResponse;
// get the response
using (StreamReader stIn = new StreamReader(request.GetResponse().GetResponseStream()))
{
strResponse = stIn.ReadToEnd();
stIn.Close();
}
// and here is the results
FullReturnLine = HttpContext.Current.Server.UrlDecode(strResponse);
