用于 Azure Stack Hub 资源管理器的 Java SDK 提供了相关工具来帮助构建和管理基础结构。The Java SDK for the Azure Stack Hub Resource Manager provides tools to help you build and manage your infrastructure. 该 SDK 中的资源提供程序包括了计算、网络、存储、应用服务和 Key Vault。Resource providers in the SDK include Compute, Networking, Storage, App Services, and Key Vault.

Java SDK 纳入了 API 配置文件，其方法是：在 Pom.xml 文件中包括依赖项，由后者加载 .java 文件中的正确模块 。The Java SDK incorporates API profiles by including dependencies in the Pom.xml file that loads the correct modules in the .java file. 不过，可以添加多个作为依赖项的配置文件，例如，添加 2019-03-01-hybrid 或 latest 作为 Azure 配置文件。However, you can add multiple profiles as dependencies, such as the 2019-03-01-hybrid, or latest, as the Azure profile. 使用这些依赖项来加载正确的模块，这样在创建资源类型时，就可以从这些配置文件中选择要使用的 API 版本。Using these dependencies loads the correct module so that when you create your resource type, you can select which API version from those profiles you want to use. 这样就可以使用 Azure 中的最新版本，同时使用 Azure Stack Hub 的最新 API 版本进行开发。This enables you to use the latest versions in Azure, while developing against the most current API versions for Azure Stack Hub.

使用 Java SDK 可以获得真正的混合云开发人员体验。Using the Java SDK enables a true hybrid cloud developer experience. Java SDK 中的 API 配置文件可以用来在公有云 Azure 资源和 Azure Stack Hub 中的资源之间进行切换，实现混合云开发。API profiles in the Java SDK enable hybrid cloud development by helping you switch between global Azure resources and resources in Azure Stack Hub.

Java 与 API 版本配置文件Java and API version profiles

API 配置文件是资源提供程序和 API 版本的组合。An API profile is a combination of resource providers and API versions. 可以使用 API 配置文件获取资源提供程序包中每个资源类型的最新且最稳定的版本。Use an API profile to get the latest, most stable version of each resource type in a resource provider package.

• 若要使用所有服务的最新版本，请使用 latest 配置文件作为依赖项。To use the latest versions of all the services, use the latest profile as the dependency.

  • 若使用 latest 配置文件，则依赖项为 com.microsoft.azure。To use the latest profile, the dependency is com.microsoft.azure.

  • 若要使用 Azure Stack Hub 中提供的最新支持的服务，请使用 com.microsoft.azure.profile_2019_03_01_hybrid 配置文件。To use the latest supported services available in Azure Stack Hub, use the com.microsoft.azure.profile_2019_03_01_hybrid profile.

    • 在 Pom.xml 文件中将配置文件指定为依赖项，如果从下拉列表中选择了正确的类，则会自动加载模块（就像使用 .NET 一样） 。The profile is specified in the Pom.xml file as a dependency, which loads modules automatically if you choose the right class from the dropdown list (as you would with .NET).

  • 依赖项如下所示：Dependencies appear as follows:

    <dependency>
    <groupId>com.microsoft.azure.profile_2019_03_01_hybrid</groupId>
    <artifactId>azure</artifactId>
    <version>1.0.0-beta-1</version>
    </dependency>
    

  • 若要使用特定资源提供程序中某个资源类型的特定 API 版本，请使用通过 Intellisense 定义的特定 API 版本。To use specific API versions for a resource type in a specific resource provider, use the specific API versions defined through Intellisense.

可以在同一应用中组合所有选项。You can combine all of the options in the same app.

Azure Stack Hub 资源管理器终结点The Azure Stack Hub Resource Manager endpoint

Azure 资源管理器是一种管理框架，可供管理员用来部署、管理和监视 Azure 资源。Azure Resource Manager is a management framework that allows admins to deploy, manage, and monitor Azure resources. Azure 资源管理器可以通过单个操作以组任务而不是单个任务的形式处理这些任务。Azure Resource Manager can handle these tasks as a group, rather than individually, in a single operation.

可以从资源管理器终结点获取元数据信息。You can get the metadata info from the Resource Manager endpoint. 该终结点返回 JSON 文件，其中包含运行代码所需的信息。The endpoint returns a JSON file with the info required to run your code.

请注意以下事项：Note the following considerations:

• ASDK 中的 ResourceManagerUrl 为：https://management.local.azurestack.external/。The ResourceManagerUrl in the ASDK is: https://management.local.azurestack.external/.

• 集成系统中的 ResourceManagerUrl 为 https://management.region.<fqdn>/，其中 <fqdn> 是完全限定的域名。The ResourceManagerUrl in integrated systems is: https://management.region.<fqdn>/, where <fqdn> is your fully qualified domain name.

检索所需的元数据：<ResourceManagerUrl>/metadata/endpoints?api-version=1.0。To retrieve the metadata required: <ResourceManagerUrl>/metadata/endpoints?api-version=1.0.

示例 JSON 文件：Sample JSON file:

{
   "galleryEndpoint": "https://portal.local.azurestack.external:30015/",
   "graphEndpoint": "https://graph.chinacloudapi.cn/",

Azure Java SDK API 配置文件的使用Azure Java SDK API profile usage

以下代码用于在 Azure Stack Hub 上对服务主体进行身份验证。The following code authenticates the service principal on Azure Stack Hub. 它使用租户 ID 和特定于 Azure Stack Hub 的身份验证基准创建令牌：It creates a token using the tenant ID and the authentication base, which is specific to Azure Stack Hub:

AzureTokenCredentials credentials = new ApplicationTokenCredentials(client, tenant, key, AZURE_STACK)
                    .withDefaultSubscriptionID(subscriptionID);
Azure azureStack = Azure.configure()
                    .withLogLevel(com.microsoft.rest.LogLevel.BASIC)
                    .authenticate(credentials, credentials.defaultSubscriptionID());

此代码可让你使用 API 配置文件依赖项将应用成功部署到 Azure Stack Hub。This code enables you to use the API profile dependencies to deploy your app successfully to Azure Stack Hub.

定义 Azure Stack Hub 环境设置函数Define Azure Stack Hub environment setting functions

若要将 Azure Stack Hub 云注册到正确的终结点，请使用以下代码：To register the Azure Stack Hub cloud with the correct endpoints, use the following code:

// Get Azure Stack Hub cloud endpoints
final HashMap<String, String> settings = getActiveDirectorySettings(armEndpoint);

AzureEnvironment AZURE_STACK = new AzureEnvironment(new HashMap<String, String>() {
                {
                    put("managementEndpointUrl", settings.get("audience"));
                    put("resourceManagerEndpointUrl", armEndpoint);
                    put("galleryEndpointUrl", settings.get("galleryEndpoint"));
                    put("activeDirectoryEndpointUrl", settings.get("login_endpoint"));
                    put("activeDirectoryResourceID", settings.get("audience"));
                    put("activeDirectoryGraphResourceID", settings.get("graphEndpoint"));
                    put("storageEndpointSuffix", armEndpoint.substring(armEndpoint.indexOf('.')));
                    put("keyVaultDnsSuffix", ".vault" + armEndpoint.substring(armEndpoint.indexOf('.')));
                }
            });

前面代码中的 getActiveDirectorySettings 调用从元数据终结点检索终结点。The getActiveDirectorySettings call in the previous code retrieves the endpoints from the metadata endpoints. 它从所做的调用声明环境变量：It states the environment variables from the call that's made:

public static HashMap<String, String> getActiveDirectorySettings(String armEndpoint) {

    HashMap<String, String> adSettings = new HashMap<String, String>();
    try {

        // create HTTP Client
        HttpClient httpClient = HttpClientBuilder.create().build();

        // Create new getRequest with below mentioned URL
        HttpGet getRequest = new HttpGet(String.format("%s/metadata/endpoints?api-version=1.0",
                             armEndpoint));

        // Add additional header to getRequest which accepts application/xml data
        getRequest.addHeader("accept", "application/xml");

        // Execute request and catch response
        HttpResponse response = httpClient.execute(getRequest);

        // Check for HTTP response code: 200 = success
        if (response.getStatusLine().getStatusCode() != 200) {
            throw new RuntimeException("Failed : HTTP error code : " + response.getStatusLine().getStatusCode());
        }

        String responseStr = EntityUtils.toString(response.getEntity());
        JSONObject responseJson = new JSONObject(responseStr);
        adSettings.put("galleryEndpoint", responseJson.getString("galleryEndpoint"));
        JSONObject authentication = (JSONObject) responseJson.get("authentication");
        String audience = authentication.get("audiences").toString().split("\"")[1];
        adSettings.put("login_endpoint", authentication.getString("loginEndpoint"));
        adSettings.put("audience", audience);
        adSettings.put("graphEndpoint", responseJson.getString("graphEndpoint"));

    } catch (ClientProtocolException cpe) {
        cpe.printStackTrace();
        throw new RuntimeException(cpe);
    } catch (IOException ioe) {
        ioe.printStackTrace();
        throw new RuntimeException(ioe);
    }
    return adSettings;
}
