[英]AcquireTokenByAuthorizationCode throw new exception in single tenant application using ASP.NET MVC using Azure Active Directory
我尝试了本教程,因为我想使用 Microsoft Graph API 在 Microsoft Teams 中创建庞大的团队。 与本教程的唯一区别是我在 Azure AD 管理中心的 Authentication 部分使用了下一个选项:
"Accounts in this organizational directory only (myuniversity only - Single tenant)"
因此,我更改了代码以将端点用于单租户
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = appId,
//Authority = "https://login.microsoftonline.com/common/v2.0",//
Authority = "https://login.microsoftonline.com/{tenantid}/v2.0",
Scope = $"openid email profile offline_access {graphScopes}",
RedirectUri = redirectUri,
PostLogoutRedirectUri = redirectUri,
TokenValidationParameters = new TokenValidationParameters
{
// For demo purposes only, see below
ValidateIssuer = false
// In a real multi-tenant app, you would add logic to determine whether the
// issuer was from an authorized tenant
//ValidateIssuer = true,
//IssuerValidator = (issuer, token, tvp) =>
//{
// if (MyCustomTenantValidation(issuer))
// {
// return issuer;
// }
// else
// {
// throw new SecurityTokenInvalidIssuerException("Invalid issuer");
// }
//}
},
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = OnAuthenticationFailedAsync,
AuthorizationCodeReceived = OnAuthorizationCodeReceivedAsync
}
}
);
}
在对用户进行身份验证后,我运行到OnAuthorizationCodeReceivedAsync
方法的代码,但在AcquireTokenByAuthorizationCode
方法中出现异常
这是方法
private async Task OnAuthorizationCodeReceivedAsync(AuthorizationCodeReceivedNotification notification)
{
var idClient = ConfidentialClientApplicationBuilder.Create(appId)
.WithRedirectUri(redirectUri)
.WithClientSecret(appSecret)
.Build();
var accounts = await idClient.GetAccountsAsync();
string message;
string debug;
try
{
string[] scopes = graphScopes.Split(' ');
var result = await idClient.AcquireTokenByAuthorizationCode(scopes, notification.Code).ExecuteAsync();
message = "Access token retrieved.";
debug = result.AccessToken;
}
catch (MsalException ex)
{
message = "AcquireTokenByAuthorizationCodeAsync threw an exception";
debug = ex.Message;
}
var queryString = $"message={message}&debug={debug}";
if (queryString.Length > 2048)
{
queryString = queryString.Substring(0, 2040) + "...";
}
notification.HandleResponse();
notification.Response.Redirect($"/Home/Error?{queryString}");
}
例外是:
AcquireTokenByAuthorizationCodeAsync 抛出异常
AADSTS50194:应用程序“应用程序 ID”(ASP.NET 图形教程)未配置为多租户应用程序。 在“2018 年 10 月 15 日”之后创建的此类应用程序不支持使用 /common 端点。 使用特定于租户的端点或将应用程序配置为多租户。 跟踪 ID:5f0fbf2e-5d63-40d4-a833-ca8627a02d00

我只想为我的组织使用单租户身份验证
如果您想通过 MSAL.NET 要求某个特定租户的 AD 令牌,您可以通过提及特定权限来告诉 SDK 从哪个租户获取令牌。 更多详情,请参阅此处。
例如
private static string appId = ConfigurationManager.AppSettings["ida:AppId"];
private static string appSecret = ConfigurationManager.AppSettings["ida:AppSecret"];
private static string redirectUri = ConfigurationManager.AppSettings["ida:RedirectUri"];
private static string graphScopes = ConfigurationManager.AppSettings["ida:AppScopes"];
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = appId,
Authority = "https://login.microsoftonline.com/<your tenant id>/v2.0",
Scope = $"openid email profile offline_access {graphScopes}",
RedirectUri = redirectUri,
PostLogoutRedirectUri = redirectUri,
TokenValidationParameters = new TokenValidationParameters
{
// For demo purposes only, see below
ValidateIssuer = false
// In a real multi-tenant app, you would add logic to determine whether the
// issuer was from an authorized tenant
//ValidateIssuer = true,
//IssuerValidator = (issuer, token, tvp) =>
//{
// if (MyCustomTenantValidation(issuer))
// {
// return issuer;
// }
// else
// {
// throw new SecurityTokenInvalidIssuerException("Invalid issuer");
// }
//}
},
Notifications = new OpenIdConnectAuthenticationNotifications
{
AuthenticationFailed = OnAuthenticationFailedAsync,
AuthorizationCodeReceived = OnAuthorizationCodeReceivedAsync
}
}
);
}
private async Task OnAuthorizationCodeReceivedAsync(AuthorizationCodeReceivedNotification notification)
{
var idClient = ConfidentialClientApplicationBuilder.Create(appId)
.WithRedirectUri(redirectUri)
.WithClientSecret(appSecret)
.WithAuthority("https://login.microsoftonline.com/<your tenant id>")
.Build();
string message;
string debug;
try
{
string[] scopes = graphScopes.Split(' ');
var result = await idClient.AcquireTokenByAuthorizationCode(
scopes, notification.Code).ExecuteAsync();
message = "Access token retrieved.";
debug = result.AccessToken;
}
catch (MsalException ex)
{
message = "AcquireTokenByAuthorizationCodeAsync threw an exception";
debug = ex.Message;
}
var queryString = $"message={message}&debug={debug}";
if (queryString.Length > 2048)
{
queryString = queryString.Substring(0, 2040) + "...";
}
notification.HandleResponse();
notification.Response.Redirect($"/Home/Error?{queryString}");
}
private Task OnAuthenticationFailedAsync(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
notification.HandleResponse();
string redirect = $"/Home/Error?message={notification.Exception.Message}";
if (notification.ProtocolMessage != null && !string.IsNullOrEmpty(notification.ProtocolMessage.ErrorDescription))
{
redirect += $"&debug={notification.ProtocolMessage.ErrorDescription}";
}
notification.Response.Redirect(redirect);
return Task.FromResult(0);
}
更改后我得到“'authority'应该是URI格式。Parameternamn:authority”
