I've asked this question on the UWP forum but have been directed here to see if anyone can help.
I use the OnlineIdAuthenticator from a C++ UWP app to access a users OneDrive files. This works well. However after an hour the token expires so I need to refresh it. I tried two approaches:
1) I took a look at the OneNote sample here: https://github.com/OneNoteDev/OneNoteAPISampleWinUniversal
Looking at AttemptAccessTokenRequest() within OneNoteServiceSamplesWinUniversal.Shared/OneNoteApi/LiveIdAuth.cs:
var createMessage = new HttpRequestMessage(HttpMethod.Post, MsaTokenRefreshUrl)
{
Content = new StringContent(
String.Format(CultureInfo.InvariantCulture, TokenRefreshRequestBody,
ClientId,
TokenRefreshRedirectUri,
_refreshToken),
Encoding.UTF8,
TokenRefreshContentType)
};
var httpClient = new HttpClient();
HttpResponseMessage response = await httpClient.SendAsync(createMessage);
await ParseRefreshTokenResponse(response);
}
However I get a 400 response: error=invalid_request error_description=The provided request must include a 'refresh_token' input parameter.
I can't see any way to obtain the refresh token via the OnlineIdAuthenticator.
2) I call OnlineIdAuthenticator::AuthenticateUserAsync() again but this time only with a "wl.signin" scope, as mentioned in LiveAuthClient.cs from the LiveSDK:
https://github.com/liveservices/LiveSDK
This works and I get a new token! Unfortunately when I try to refresh it again (at the 2hr mark) it returns the same token and I then get a 401 unauthorized when I try to use it.
So has anyone successfully refreshed the access token via OnlineIdAuthenticator ? If so I'd appreciate knowing how you've done it.
Many thanks.
