You can use IRefreshTokenHandler
to save token as following example:
public class RefreshTokenHandler : IRefreshTokenHandler
{
private string path = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + "\\oneDrive\\RefreshTokenHandler\\RefreshTokenInfo.RefreshToken-me";
public Task<RefreshTokenInfo> RetrieveRefreshTokenAsync()
{
return Task.Factory.StartNew<RefreshTokenInfo>(() =>
{
if (File.Exists(path))
{
return new RefreshTokenInfo(File.ReadAllText(path));
}
return null;
});
}
public Task SaveRefreshTokenAsync(RefreshTokenInfo tokenInfo)
{
// Note:
// 1) In order to receive refresh token, wl.offline_access scope is needed.
// 2) Alternatively, we can persist the refresh token.
return Task.Factory.StartNew(() =>
{
if (File.Exists(path)) File.Delete(path);
if (!Directory.Exists(Path.GetDirectoryName(path))) Directory.CreateDirectory(Path.GetDirectoryName(path));
File.AppendAllText(path, tokenInfo.RefreshToken);
});
}
}
after that you get session as following:
RefreshTokenHandler handler = new RefreshTokenHandler();
liveAuthClient = new LiveAuthClient(ClientID, handler);
var Session = liveAuthClient.InitializeAsync(scopes).Result.Session;
if (Session == null)
{
webBrowser1.Navigate(liveAuthClient.GetLoginUrl(scopes));
}
else
{
try
{
this.liveConnectClient = new LiveConnectClient(Session);
LiveOperationResult meRs = await this.liveConnectClient.GetAsync("me");
dynamic meData = meRs.Result;
if (string.Equals(meData.emails.account, MyAppUser.EmailAddress))
MessageBox.Show("Successful login: " + meData.name);
}
catch (LiveAuthException aex)
{
MessageBox.Show("Failed to retrieve access token. Error: " + aex.Message);
}
catch (LiveConnectException cex)
{
MessageBox.Show("Failed to retrieve the user's data. Error: " + cex.Message);
}
}
