Question

我第一次针对Azure Active Directory B2C进行开发。我正在开发WPF /桌面应用程序。

登录和注销一直运行良好，直到今天莫名其妙地停止了工作，现在在登录过程中引发了以下异常。

AADB2C90079: Clients must send a client_secret when redeeming a confidential grant.

有一个建议，我需要刷新此堆栈溢出问题中概述的令牌： Azure B2C Custom Policies: Invalid Request, client secret error

但是我丝毫不知道如何执行此操作。

这是我的登录代码（正在引发异常的Await PublicClientApp.AcquireTokenAsync（...））

Public Async Function SignIn() As Task(Of Boolean)

    Dim authResult As AuthenticationResult = Nothing
    Dim accounts As IEnumerable(Of IAccount) = Await PublicClientApp.GetAccountsAsync()

    Try
        authResult = Await PublicClientApp.AcquireTokenAsync(ApiScopes, GetUserByPolicy(accounts, PolicySignUpSignIn), UIBehavior.SelectAccount, String.Empty, Nothing, Authority)
        userProf = Await GetUserInformation()
        SignInState = SignInStateEnum.SignedIn
        Return True
    Catch ex As MsalServiceException

        Try
            If ex.Message.Contains("AADB2C90118") Then
                authResult = PublicClientApp.AcquireTokenAsync(ApiScopes, GetUserByPolicy(accounts, PolicySignUpSignIn), UIBehavior.SelectAccount, String.Empty, Nothing, AuthorityResetPassword).Result
                userProf = GetUserInformation().Result
                SignInState = SignInStateEnum.SignedIn
                Return True
            Else
                logger.Error($"Error Acquiring Token:{Environment.NewLine}{ex}")
                logger.Error("Exception Raised", ex)
                userProf = Nothing
                SignInState = SignInStateEnum.SignedOut
                Return False
            End If
        Catch __unusedException1__ As Exception
            logger.Error("Exception Raised", __unusedException1__)
            userProf = Nothing
            SignInState = SignInStateEnum.SignedOut
            Return False
        End Try

    Catch ex As Exception
        logger.Error($"Users:{String.Join(",", accounts.[Select](Function(u) u.Username))}{Environment.NewLine}Error Acquiring Token:{Environment.NewLine}{ex}")
        logger.Error("Exception Raised", ex)
        userProf = Nothing
        SignInState = SignInStateEnum.SignedOut
        Return False
    End Try

End Function
