Below code works fine personal Id, but does not return token when we are using service account which have pro licencese and O365 license as F1
HttpWebRequest request = System.Net.HttpWebRequest.CreateHttp("https://login.windows.net/common/oauth2/token");
//POST web request to create a datasource.
request.KeepAlive = true;
request.Method = "POST";
request.ContentLength = 0;
request.ContentType = "application/x-www-form-urlencoded";
//Add token to the request header
request.Headers.Add("Authorization", String.Format("Bearer {0}", token));
NameValueCollection parsedQueryString = HttpUtility.ParseQueryString(String.Empty);
parsedQueryString.Add("client_id", clientID);
parsedQueryString.Add("grant_type", "password");
parsedQueryString.Add("resource", resourceUri);
parsedQueryString.Add("username", username);
parsedQueryString.Add("password", password);
string postdata = parsedQueryString.ToString();
//POST web request
byte[] dataByteArray = System.Text.Encoding.ASCII.GetBytes(postdata); ;
request.ContentLength = dataByteArray.Length;
//Write JSON byte[] into a Stream
using (Stream writer = request.GetRequestStream())
{
writer.Write(dataByteArray, 0, dataByteArray.Length);
var response = (HttpWebResponse)request.GetResponse();
var responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
dynamic responseJson = JsonConvert.DeserializeObject<dynamic>(responseString);
return responseJson["access_token"];
}
when we use SA we get below error; The remote server returned an error: (400) Bad Request; But same SA works fine using below approach...
// Create a user password cradentials.
var credential = new UserPasswordCredential(Username, Password);
// Authenticate using created credentials
var authenticationContext = new AuthenticationContext(AuthorityUrl);
var authenticationResult = await authenticationContext.AcquireTokenAsync(ResourceUrl, ApplicationId, credential);
if (authenticationResult == null)
{
result.ErrorMessage = "Authentication Failed.";
return View(result);
}
var tokenCredentials = new TokenCredentials(authenticationResult.AccessToken, "Bearer");
