我正在尝试从outlooo 365 API获取一些日历项目
我从样本中得到的代码是:
public async Task<ActionResult> Index() {
// fetch from stuff user claims
var signInUserId = ClaimsPrincipal.Current.FindFirst(ClaimTypes.NameIdentifier).Value;
var userObjectId = ClaimsPrincipal.Current.FindFirst(SettingsHelper.ClaimTypeObjectIdentifier).Value;
// discover contact endpoint
var clientCredential = new ClientCredential(SettingsHelper.ClientId, SettingsHelper.ClientSecret);
var userIdentifier = new UserIdentifier(userObjectId, UserIdentifierType.UniqueId);
// create auth context
AuthenticationContext authContext = new AuthenticationContext(SettingsHelper.AzureADAuthority, new EFADALTokenCache(signInUserId));
// create O365 discovery client
DiscoveryClient discovery = new DiscoveryClient(new Uri(SettingsHelper.O365DiscoveryServiceEndpoint),
async () => {
var authResult = await authContext.AcquireTokenSilentAsync(SettingsHelper.O365DiscoveryResourceId, clientCredential, userIdentifier);
return authResult.AccessToken;
});
// query discovery service for endpoint for 'calendar' endpoint
var dcr = await discovery.DiscoverCapabilityAsync("Calendar");
// create Outlook client using the calendar api endpoint
OutlookServicesClient client = new OutlookServicesClient(dcr.ServiceEndpointUri,
async () => {
var authResult = await authContext.AcquireTokenSilentAsync(dcr.ServiceResourceId, clientCredential,
userIdentifier);
return authResult.AccessToken;
});
// get contacts
var results = await client.Me.Events.Take(20).ExecuteAsync();
ViewBag.Events = results.CurrentPage.OrderBy(c => c.Start);
return View();
}
这是基于此处提供的样本&gt; https://github.com/OfficeDev/TrainingContent/tree/master/O3651/O3651-5%20Getting%20started%20with%20Office%20365%20APIs/Completed%20Projects
我收到了这个错误:
无法以静默方式获取令牌。调用方法AcquireToken 描述:执行当前Web请求期间发生未处理的异常。请查看堆栈跟踪以获取有关错误及其源自代码的位置的更多信息。
异常详细信息:Microsoft.IdentityModel.Clients.ActiveDirectory.AdalSilentTokenAcquisitionException:无法以静默方式获取令牌。调用方法AcquireToken
来源错误:

这是settingshelper
public class SettingsHelper {
public static string ClientId {
get { return ConfigurationManager.AppSettings["ida:ClientID"]; }
}
public static string ClientSecret {
get { return ConfigurationManager.AppSettings["ida:Password"]; }
}
public static string AzureAdTenantId {
get { return ConfigurationManager.AppSettings["ida:TenantId"]; }
}
public static string O365DiscoveryServiceEndpoint {
get { return "https://api.office.com/discovery/v1.0/me/"; }
}
public static string O365DiscoveryResourceId {
get { return "https://api.office.com/discovery/"; }
}
public static string AzureAdGraphResourceId {
get { return "https://graph.windows.net"; }
}
public static string AzureADAuthority {
get { return string.Format("https://login.windows.net/{0}/", AzureAdTenantId); }
}
public static string ClaimTypeObjectIdentifier {
get { return "http://schemas.microsoft.com/identity/claims/objectidentifier"; }
}
}
我很确定clientid和secret是可以的,因为我已经在azure AD上创建了应用程序。
答案 0 :(得分:3)
我将设置帮助器与我的项目中的设置帮助器进行了比较,该设置正确地进行了身份验证。唯一的区别是您在AzureADAuthority属性的末尾有额外的'/'。
public static string AzureADAuthority {
get {return string.Format("https://login.windows.net/{0}", AzureAdTenantId); }
}
答案 1 :(得分:1)
作为提示,当我尝试使用VS Community 2015实现Video REST API演示应用程序时,我遇到了同样的错误。我可以修复它更新所有软件包,我注意到有一个特定的与微软身份有关或类似的东西,也许那个包导致了错误。
当我使用VS Community 2013 Update 4使用相同的代码时,我没有任何问题。
此致
答案 2 :(得分:0)
不幸的是,这是vs 2015 RC的一个错误,在RTM版本上,相同的代码完全正常。
