我有一个项目，我已经开始构建，并希望让我们使用Azure AD B2C - 我已经关注了一些教程，并通过从头开始创建一个新的MVC应用程序进行测试，但是，当我尝试实现时，我得到了它的工作它进入我现有的项目，然后它不会重定向到SignIn / SignUp页面（这是login.microsoftonline.com ...）url。我知道我的代码可以重定向到这个url，因为它在我创建的新项目上进行测试，所以不知道为什么它不会在我现有的项目上。
这是在我的Web.Config中：
<add key="ida:Tenant" value="Name.onmicrosoft.com" />
<add key="ida:ClientId" value="GUID" />
<add key="ida:ClientSecret" value="Secret" />
<add key="ida:AadInstance" value="https://login.microsoftonline.com/tfp/{0}/{1}/v2.0/.well-known/openid-configuration" />
<add key="ida:RedirectUri" value="https://localhost:44382/" />
<add key="ida:SignUpSignInPolicyId" value="B2C_1_SiUpIn" />
<add key="ida:EditProfilePolicyId" value="B2C_1_SiPe" />
<add key="ida:ResetPasswordPolicyId" value="B2C_1_SSPR" />
ActionLink的：
@Html.ActionLink("Sign up / Sign in", "SignUpSignIn", "Account", routeValues: null, htmlAttributes: new { id = "signUpSignInLink" })
这是我正在调用的SignUpSignIn函数：
[AllowAnonymous]
public void SignUpSignIn()
{
// Use the default policy to process the sign up / sign in flow
if (!Request.IsAuthenticated)
{
HttpContext.GetOwinContext().Authentication.Challenge();
return;
}
Response.Redirect("/");
}
以下是我的启动代码：
public partial class Startup
{
// App config settings
public static string ClientId = ConfigurationManager.AppSettings["ida:ClientId"];
public static string ClientSecret = ConfigurationManager.AppSettings["ida:ClientSecret"];
public static string AadInstance = ConfigurationManager.AppSettings["ida:AadInstance"];
public static string Tenant = ConfigurationManager.AppSettings["ida:Tenant"];
public static string RedirectUri = ConfigurationManager.AppSettings["ida:RedirectUri"];
public static string ServiceUrl = ConfigurationManager.AppSettings["api:TaskServiceUrl"];
// B2C policy identifiers
public static string SignUpSignInPolicyId = ConfigurationManager.AppSettings["ida:SignUpSignInPolicyId"];
public static string EditProfilePolicyId = ConfigurationManager.AppSettings["ida:EditProfilePolicyId"];
public static string ResetPasswordPolicyId = ConfigurationManager.AppSettings["ida:ResetPasswordPolicyId"];
public static string DefaultPolicy = SignUpSignInPolicyId;
// API Scopes
public static string ApiIdentifier = ConfigurationManager.AppSettings["api:ApiIdentifier"];
public static string ReadTasksScope = ApiIdentifier + ConfigurationManager.AppSettings["api:ReadScope"];
public static string WriteTasksScope = ApiIdentifier + ConfigurationManager.AppSettings["api:WriteScope"];
public static string[] Scopes = new string[] { ReadTasksScope, WriteTasksScope };
// OWIN auth middleware constants
public const string ObjectIdElement = "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/nameidentifier";
// Authorities
public static string Authority = String.Format(AadInstance, Tenant, DefaultPolicy);
/*
* Configure the OWIN middleware
*/
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
// Generate the metadata address using the tenant and policy information
MetadataAddress = String.Format(AadInstance, Tenant, DefaultPolicy),
// These are standard OpenID Connect parameters, with values pulled from web.config
ClientId = ClientId,
RedirectUri = RedirectUri,
PostLogoutRedirectUri = RedirectUri,
// Specify the callbacks for each type of notifications
Notifications = new OpenIdConnectAuthenticationNotifications
{
RedirectToIdentityProvider = OnRedirectToIdentityProvider,
AuthorizationCodeReceived = OnAuthorizationCodeReceived,
AuthenticationFailed = OnAuthenticationFailed,
},
// Specify the claims to validate
TokenValidationParameters = new TokenValidationParameters
{
NameClaimType = "name"
},
// Specify the scope by appending all of the scopes requested into one string (separated by a blank space)
Scope = $"openid profile offline_access {ReadTasksScope} {WriteTasksScope}"
}
);
}
/*
* On each call to Azure AD B2C, check if a policy (e.g. the profile edit or password reset policy) has been specified in the OWIN context.
* If so, use that policy when making the call. Also, don't request a code (since it won't be needed).
*/
private Task OnRedirectToIdentityProvider(RedirectToIdentityProviderNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
var policy = notification.OwinContext.Get<string>("Policy");
if (!string.IsNullOrEmpty(policy) && !policy.Equals(DefaultPolicy))
{
notification.ProtocolMessage.Scope = OpenIdConnectScopes.OpenId;
notification.ProtocolMessage.ResponseType = OpenIdConnectResponseTypes.IdToken;
notification.ProtocolMessage.IssuerAddress = notification.ProtocolMessage.IssuerAddress.ToLower().Replace(DefaultPolicy.ToLower(), policy.ToLower());
}
return Task.FromResult(0);
}
/*
* Catch any failures received by the authentication middleware and handle appropriately
*/
private Task OnAuthenticationFailed(AuthenticationFailedNotification<OpenIdConnectMessage, OpenIdConnectAuthenticationOptions> notification)
{
notification.HandleResponse();
// Handle the error code that Azure AD B2C throws when trying to reset a password from the login page
// because password reset is not supported by a "sign-up or sign-in policy"
if (notification.ProtocolMessage.ErrorDescription != null && notification.ProtocolMessage.ErrorDescription.Contains("AADB2C90118"))
{
// If the user clicked the reset password link, redirect to the reset password route
notification.Response.Redirect("/Account/ResetPassword");
}
else if (notification.Exception.Message == "access_denied")
{
notification.Response.Redirect("/");
}
else
{
notification.Response.Redirect("/Home/Error?message=" + notification.Exception.Message);
}
return Task.FromResult(0);
}
/*
* Callback function when an authorization code is received
*/
private async Task OnAuthorizationCodeReceived(AuthorizationCodeReceivedNotification notification)
{
// Extract the code from the response notification
var code = notification.Code;
string signedInUserID = notification.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
TokenCache userTokenCache = new MSALSessionCache(signedInUserID, notification.OwinContext.Environment["System.Web.HttpContextBase"] as HttpContextBase).GetMsalCacheInstance();
ConfidentialClientApplication cca = new ConfidentialClientApplication(ClientId, Authority, RedirectUri, new ClientCredential(ClientSecret), userTokenCache, null);
try
{
AuthenticationResult result = await cca.AcquireTokenByAuthorizationCodeAsync(code, Scopes);
}
catch (Exception ex)
{
//TODO: Handle
throw;
}
}
}
当我点击此ActionLink时，它会点击控制器，但之后不会重定向，它只会返回此URL：
https://localhost:44382/account/login?ReturnUrl=%2faccount%2fsignupsignin
我必须提到的一件事是，我购买了一个我正在使用的模板 - 不知道这是否会产生任何影响 - 我完全难过，不知道我还能看到什么....
如果您需要我尚未发布的任何内容，请告知我们。
如果有人能够帮助我朝着正确的方向前进，我将不胜感激。
谢谢！

所以不幸的是我没有找到解决这个问题的具体解决方案，因为我无法确定究竟是什么问题。但是，我确实通过创建一个全新的项目来解决问题，并将项目从我购买的模板（这是一个mvc项目）移动到新创建的项目中。因为我需要修复因此而发生的任何错误，但是它最终起作用了。购买的模板中显然存在导致问题的原因。
所以只是给出一些上下文 - 我买的模板有不同的框架你可以使用（MVC，PHP，Angular等），我使用了包含模板的MVC项目，我刚刚在MVC项目上构建，所以我假设该项目中有一些东西导致了这个问题。
