c# - Azure C# KeyVaultErrorException : Operation returned an invalid status code 'Forbidden'

Question

我正在编写一个程序，尝试通过访问 KeyVault 来访问 Azure 表存储的 secret (OneAuthZAuthentication)。我正在按照本教程中列出的步骤操作:https://jeanpaul.cloud/2019/12/07/azure-key-vault-access-from-c/

我创建了一个名为 ITALocalBuildSecrets 的 Key Vault:

使用以下 DNS 名称:https://italocalbuildsecrets.vault.azure.net/

我还有另一个 secret ，其名称如下 (OneAuthZAuthentication):

我已在事件目录中创建了一个应用程序 (OneAuthZUserApplication)，您可以看到下面显示的应用程序(客户端)ID: 奥 git _a我为 OneAuthZUserApplication 创建了一个客户端 key : 奥 git _a我授权控制台应用程序 (OneAuthZUserApplication) 作为访问策略: 奥 git _a并且您可以清楚地看到正在注册的访问策略:

下面是我正在运行的代码:

    // Retrieves the access token necessary to gain authentication into the key vault
    [FunctionName("GetToken")]
    public static async System.Threading.Tasks.Task<string> GetToken(string authority, string resource, string scope)
    { 
        var clientId = "5cf497b0-3467-456a-a03a-4d4414b*****"; // Stars are for security reasons :D
        var clientSecret = "468.26i5Wc.nQ6TYL-eOvBmcto.t.*****"; // Stars are for security reasons
        ClientCredential credential = new ClientCredential(clientId, clientSecret);
        var context = new AuthenticationContext(authority, TokenCache.DefaultShared);
        var result = await context.AcquireTokenAsync(resource, credential);
        return result.AccessToken;
    }

    // Retrieves the access key vault accountKey (needed to authenticate access into the role assignments table)
    public static string GetVaultValue()
    {
        KeyVaultClient client = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetToken));
        var vaultAddress = "https://italocalbuildsecrets.vault.azure.net/";
        var secretName = "OneAuthZAuthentication";
        var secret = client.GetSecretAsync(vaultAddress, secretName).GetAwaiter().GetResult();
        return secret.Value;
    }

    [FunctionName("Function1")]
    // Function that reads a small portion of the role assignments table (OneAuthZRoleAssignments) every 
    // configurable number of times
    public static async System.Threading.Tasks.Task RunAsync([TimerTrigger("%TimerTriggerPeriod%")]TimerInfo myTimer, ILogger log)
    {
        Console.WriteLine($"Secret Value from Vault is: {GetVaultValue()}");
    }

我收到以下错误:

Function1. Microsoft.Azure.KeyVault: Operation returned an invalid status code 'Forbidden'.   

考虑到我已将 OneAuthZUserApplication 应用程序授权给 key 保管库，这似乎很奇怪。
