Azure从Azure Java SDK检索VirtualMachines的PublicIPAddress

Question

我尝试使用以下代码来检索公共IP的大小

Configuration config = ManagementConfiguration.configure(
          new URI(uri), 
          subscriptionId,
          keyStoreLocation, // the file path to the JKS
          keyStorePassword, // the password for the JKS
          KeyStoreType.jks // flags that I'm using a JKS keystore
        );

NetworkResourceProviderClient  networkResourceProviderClient = NetworkResourceProviderService.create(config);
           PublicIpAddressListResponse PublicIpAddressListResponse =networkResourceProviderClient.getPublicIpAddressesOperations().listAll();
           ArrayList<PublicIpAddress> PublicIpAddressList =PublicIpAddressListResponse.getPublicIpAddresses();
           System.out.println(PublicIpAddressList.size());

使用Azure AD ServicePrincipal身份验证，它返回-0

使用带有 “ https://management.azure.com/ ”
API的证书身份验证，它将返回-AuthenticationFailed：

Exception in thread "main" com.microsoft.windowsazure.exception.ServiceException: AuthenticationFailed: Authentication failed. The 'Authorization' header is not present or provided in an invalid format.
    at com.microsoft.windowsazure.exception.ServiceException.createFromJson(ServiceException.java:290)
    at com.microsoft.azure.management.network.PublicIpAddressOperationsImpl.listAll(PublicIpAddressOperationsImpl.java:1443)
    at com.microsoft.azure.auth.Program.main(Program.java:50)

任何想法如何检索所有虚拟机的公共IP地址？或如何进行身份验证以获得IP值？

Answer 1

该问题是由使用不正确的身份验证引起的。

下面的身份验证代码仅适用于Azure服务管理。

Configuration config = ManagementConfiguration.configure(
          new URI("https://management.core.windows.net), 
          subscriptionId,
          keyStoreLocation, // the file path to the JKS
          keyStorePassword, // the password for the JKS
          KeyStoreType.jks // flags that I'm using a JKS keystore
        );

为验证Azure资源管理，文档“验证Azure资源管理请求”（https://msdn.microsoft.com/en-
us/library/azure/dn790557.aspx
）表示“您使用以下命令对资源执行的所有任务必须使用Azure Active
Directory对Azure资源管理器进行身份验证。

因此，您需要使用您的subscription-id，tenant-id，client-id和client-secret修改身份验证配置代码，如下所示：

private static AuthenticationResult getAccessTokenFromServicePrincipalCredentials() throws
            ServiceUnavailableException, MalformedURLException, ExecutionException, InterruptedException {
        AuthenticationContext context;
        AuthenticationResult result = null;
        ExecutorService service = null;
        try {
            service = Executors.newFixedThreadPool(1);
            // TODO: add your tenant id
            context = new AuthenticationContext("https://login.windows.net/" + "<your tenant id>",
                    false, service);
            // TODO: add your client id and client secret
            ClientCredential cred = new ClientCredential("<your client id>",
                    "<your client secret>");
            Future<AuthenticationResult> future = context.acquireToken(
                    "https://management.azure.com/", cred, null);
            result = future.get();
        } finally {
            service.shutdown();
        }

        if (result == null) {
            throw new ServiceUnavailableException(
                    "authentication result was null");
        }
        return result;
    }


Configuration config = ManagementConfiguration.configure(
          null,
          new URI("https://management.core.windows.net), 
          "<your-subscription-id>",
          getAccessTokenFromServicePrincipalCredentials()
.getAccessToken()
        );
