Ceci est mon code pour gérer AdalToken Cache Je suis l'exception suivante Echec d'acquisition jeton en silence. méthode d'appel AcquireTokenImpossible d'acquérir le jeton en mode silencieux. méthode d'appel AcquireToken ne fonctionne pas
a cette exception dans le code ci-dessous près de var authResultDisc
// connexion SharePoint pour obtenir la liste des articles
DiscoveryClient discClient = new DiscoveryClient(SettingsHelper.DiscoveryServiceEndpointUri,
async() =>
{
var authResultDisc = await authContext.AcquireTokenSilentAsync(SettingsHelper.DiscoveryServiceResourceId, new ClientCredential(SettingsHelper.ClientId, SettingsHelper.AppKey), new UserIdentifier(userObjectId, UserIdentifierType.UniqueId));
return authResultDisc.AccessToken;
});
var dcr = await discClient.DiscoverCapabilityAsync("RootSite");
ma pensée à ce sujet est que, il dose pas de compensation les entrées de la base de données.
Quelqu'un peut m'aider à résoudre cette erreur.
L'exception semble suggérer d'essayer 'AcquireToken' - que se passe-t-il lorsque vous l'utilisez? – mjwills
