每當我將 Azure Key Vault 應用配置添加到我的 program.cs 文件時，我的 Web 應用都會遇到啟動錯誤 500.30。在本地，我可以訪問保險庫并對其進行了測試，但一旦發布，我就會收到錯誤消息。我已經嘗試將系統和用戶身份添加到我的 Web 應用程序，并通過 Azure 訪問控制和訪問策略授予它權限。我也已授予該應用程序訪問整個資源的權限。我已經注釋掉了這部分并且應用程序運行了，這就是為什么我將錯誤歸因于密鑰庫。public static IWebHost CreateWebHostBuilder(string[] args) =>           WebHost.CreateDefaultBuilder(args)// this gets commented out to run properly               .ConfigureAppConfiguration((ctx, builder) =>               {                   var keyVaultEndpoint = GetKeyVaultEndpoint();                   if (!string.IsNullOrEmpty(keyVaultEndpoint))                   {                       var azureServiceTokenProvider = new AzureServiceTokenProvider();                       var keyVaultClient = new KeyVaultClient(                           new KeyVaultClient.AuthenticationCallback(                               azureServiceTokenProvider.KeyVaultTokenCallback));                       builder.AddAzureKeyVault(                           keyVaultEndpoint, keyVaultClient, new DefaultKeyVaultSecretManager());                   }               }               ) // until here                .UseStartup<Startup>()               .Build();private static string GetKeyVaultEndpoint() => "https://<vault name>.vault.azure.net/";我希望能夠訪問密鑰庫。該應用程序在發布時拋出 HTTP 錯誤 500.30 - ANCM 進程內啟動失敗。更新：更改為 OutOfProcess 后，我現在收到錯誤 502.5。帶有以下消息：Unhandled Exception: Microsoft.Azure.Services.AppAuthentication.AzureServiceTokenProviderException: Parameters: Connection String: [No connection string specified], Resource: https://vault.azure.net, Authority: https://login.windows.net/<MyId>.
