教育令牌不刷新

Question

我有一个 ASP.NET webforms 应用程序，我在其中使用与 Azure Active Directory 关联的 Azure Key Vault。我使用了此处找到的指南 https://azure.microsoft.com/en-us/documentation/articles/storage-encrypt-decrypt-blobs-key-vault/ 从 Azure Active Directory 为我的应用程序获取令牌并使用它来访问我的密钥保管库，我最终将其用于存储加密。应用程序第一次请求令牌时一切正常，但在令牌过期后（一小时后）。应用程序不会像它应该的那样检索新令牌。我正在使用最新的稳定版本 Microsoft.IdentityModel.Clients.ActiveDirectory 2.19.208020213，并尝试了最新的预发布版 (3.5.208051316-alpha)。

GetToken 方法如下所示

 Public Async Function GetToken(authority As String, resource As String, scope As String) As Task(Of String)
    Dim authContext = New AuthenticationContext(authority)
    Dim clientCred As New ClientCredential(CloudConfigurationManager.GetSetting("ClientID"), CloudConfigurationManager.GetSetting("ClientSecret"))
    System.Diagnostics.Trace.TraceInformation("Attempting to acquire auth token")
    Dim result As AuthenticationResult = await authContext.AcquireTokenAsync(resource, clientCred)
   System.Diagnostics.Trace.TraceInformation("Auth returned")
    If result Is Nothing Then
        System.Diagnostics.Trace.TraceInformation("Auth was null")
        Throw New InvalidOperationException("Failed to obtain the JWT token")
    End If
     System.Diagnostics.Trace.TraceInformation("Returning auth access token")
    Return result.AccessToken
End Function

此处用于连接到密钥保管库

Dim cloudResolver As New KeyVaultKeyResolver(AddressOf GetToken)

GetToken 方法只是在 AcquireTokenAsync 处挂起。我在 ADAL 中打开了详细日志记录，这就是日志显示的内容，它停止了并且 GetToken 从不 returns.

此外，我尝试通过将令牌缓存设置为 Nothing 来关闭令牌缓存，然后 ADAL 甚至不会在第一次检索访问令牌。

我在这个类似的问题中找到了答案

关键是删除其中任何一个并用 await 替换它们

.GetAwaiter().GetResult()

例如这是原件

Dim theKey = cloudResolver.ResolveKeyAsync($"{CloudConfigurationManager.GetSetting("KeyVaultUrl")}Secret/", CancellationToken.None).GetAwaiter().GetResult()

已替换为

Dim theKey = await cloudResolver.ResolveKeyAsync($"{CloudConfigurationManager.GetSetting("KeyVaultUrl")}Secret/", CancellationToken.None)
