I'm trying to get data from the Microsoft Live API. However, when I try to get the access_token, I instead get a 415 (Unsupported Media Type) error message. I have looked pretty much everywhere, but I can't find any answer (that worked for me).
Here is my (partial) code that tries to get the token (dataToWrite is cut-up for readability, it's one line in the actual code):
WebRequest request;request = WebRequest.Create("https://login.live.com/oauth20_token.srf");request.Method = "POST";request.ContentType = "application/x-www-form-urlencoded";var dataToWrite = "code=[code]& client_id=[client_id]& client_secret=[client_secret]& redirect_uri=[redirect_uri]& grant_type=authorization_code";var buffer = Encoding.ASCII.GetBytes(dataToWrite);request.ContentLength = buffer.Length;var dataStream = request.GetRequestStream();dataStream.Write(buffer, 0, buffer.Length);dataStream.Close();var response = request.GetResponse();var responseStream = response.GetResponseStream();Where the '[]' are:
- [code] is a string, given by Microsoft after user logs in (this part of the code works);
- [client_id] is a string, given by Microsoft, representing my client id;
- [client_secret] is a string, given by Microsoft, representing my client secret;
- [redirect_uri] is the URL of the site's return location (same as the URL used in the code for the user consent(see [code]))
According to the manual of Microsoft Live API(http://msdn.microsoft.com/en-us/library/live/hh243647.aspx) this should work. However, the documentation isn't very detailed.
Does anyone know why I keep getting the error?
