通过 C# 访问 Azure 中的 keyvault 时引发异常

Question

我有以下代码来获取 Azure 中的密钥保管库机密：

   var kv = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetToken));
    var sec = await kv.GetSecretAsync(ConfigurationManager.AppSettings["SomeURI"]);
    secretValue = sec.Value ;

在 App Config 中我有：

<add key="SomeURI" value="https://baseURL/KeyName/b75cabsdf45667nhjhe516c674457" />

因为我在我的应用程序中多次使用它，所以我创建了一个 class 并将其命名为 class。 class 看起来像这样：

public static class KeyVaultFetch
    {
        public async static Task<string> GetCachedSecret(string secretname)
        {           
            try
            {
                string BaseUri =  ConfigurationManager.AppSettings["keyvaultBaseURI"].ToString();

                var kv = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetToken));
                var secretbundle = await kv.GetSecretAsync($"{BaseUri}{secretname}").ConfigureAwait(false);
                return secretbundle.Value;
            }
            catch (Exception ex)
            {
                log.Error("Exception raised in GetCachedSecret.");
                log.Error("Exception Details: " + ex.Message);
                log.Error("Inner Exception Details: " + ex.InnerException);
                throw;
            }
        }

        public static async Task<string> GetToken(string authority, string resource, string scope)
        {
            try
            {
                var authContext = new AuthenticationContext(authority);
                ClientCredential clientCred = new ClientCredential(clientId, clientSecret);
                AuthenticationResult result = await authContext.AcquireTokenAsync(resource, clientCred);
                if (result == null)
                    throw new InvalidOperationException("Failed to obtain the JWT token");
                return result.AccessToken;
            }
            catch (Exception ex)
            {
                log.Error("Exception raised while Getting token : " + ex.Message);
                log.Error("Inner Exception Details: " + ex.InnerException);
                throw;
            }
        }
        
    }

而且我每次都写在下面一行来获取秘密：

secretValue = await KeyVaultFetch.GetCachedSecret(keyName);

但是当我运行我的代码时，我遇到了以下异常：

Exception raised in GetCachedSecret.
Exception Details: Invalid ObjectIdentifier: https://baseURL/. Bad number of segments: 2

我做错了什么？

您应该使用带有 2 个参数的 GetSecretAsync：

await kv.GetSecretAsync(BaseUri, secretname);

至少我们的应用程序是这样的:)
