通过 .NET 库将 Azure 密钥保管库证书添加到 Azure Batch 帐户

Question

我需要自动创建 Azure Batch 帐户。其中一部分是从现有 Azure 密钥保管库向帐户添加证书。我想我拥有我需要的所有部件，但我无法将它们全部组合在一起；我有一个KeyVault.Models.CertificateBundle 对象和一个Management.Batch.Models.BatchAccount 对象，但我不知道如何让一个对象进入另一个对象。

我的代码如下所示：

// Create Batch account
var storageAccount = new Models.AutoStorageBaseProperties(storageAccountId);
mgmtClient.BatchAccount.Create(resourceGroupName, accountName,
    new Models.BatchAccountCreateParameters()
    {
        Location = clusterZone,
        AutoStorage = storageAccount
    });

string certName;
Models.CertificateCreateOrUpdateParameters certParams;

// Add certificate
using (KeyVaultClient kvClient = new KeyVaultClient(new KeyVaultClient.AuthenticationCallback(GetKeyVaultToken)))
{
    var cert = kvClient.GetCertificateAsync(certId).GetAwaiter().GetResult();
    string thumbprint = Convert.ToBase64String(cert.X509Thumbprint);
    string cer = Convert.ToBase64String(cert.Cer);
    certParams = new Models.CertificateCreateOrUpdateParameters(Convert.ToBase64String(cert.Cer), cert.Id, thumbprint: thumbprint, format: Models.CertificateFormat.Cer, type: cert.ContentType);
    certName = $"SHA1-{thumbprint}"; // not sure about this one
}

// failing with a complaint about the cert name
mgmtClient.Certificate.Create(resourceGroupName, accountName, certName, certParams);

我在这段代码中遇到的确切错误是：

'certificateName' does not match expected pattern '^[\\w]+-[\\w]+$'.

certName 看起来像 SHA1-XXXXXXXXXXXXXXXXXXXXXX+XXXX=。指纹中有一些非字母数字字符。我只是猜测这是 SHA1，但除此之外，这个名字对我来说很合适。我不确定我错过了什么。

我也很乐意接受某人对这个特定问题的更简单的解决方案。

'certificateName' 与预期的模式 '^[\w]+-[\w]+$' 不匹配。

您可以调试代码并从 Azure 密钥库检查指纹。在您的代码中，您从代码中获得的指纹与认证指纹不同。我通过以下代码获得了认证指纹。

X509Certificate2 x509 = new X509Certificate2();
x509.Import(cert.Cer);
var thumbprint = x509.Thumbprint;

以下是我用来将证书添加到 Azure 批处理帐户的演示代码。

var credentials = SdkContext.AzureCredentialsFactory.FromFile(@"cred file path");
var resourceGroup = "resourceGroup";
var accountName = "batchAccountName";
var subscriptionId = "subscriptionName";
var certificateIdentifier = "https://keyvaultName.vault.azure.net/certificates/certName/xxxxx";
var batchManagementClient = new BatchManagementClient(credentials)
        {
            SubscriptionId = subscriptionId
        };
var azureServiceTokenProvider = new AzureServiceTokenProvider();

var keyVaultClient =
            new KeyVaultClient(
                new KeyVaultClient.AuthenticationCallback(azureServiceTokenProvider.KeyVaultTokenCallback));
var cert = keyVaultClient.GetCertificateAsync(certificateIdentifier).Result;
X509Certificate2 x509 = new X509Certificate2();
x509.Import(cert.Cer);
var thumbprint = x509.Thumbprint;
var certConent = Convert.ToBase64String(cert.Cer);
var certName = $"SHA1-{thumbprint}";
var result= batchManagementClient.Certificate.CreateAsync(resourceGroup, accountName, certName, new CertificateCreateOrUpdateParametersInner
        {
            Thumbprint = thumbprint,
            Data = certConent,
            ThumbprintAlgorithm = "SHA1",
            Format = CertificateFormat.Cer,

        }).Result;
