## 1、功能介绍

弹性伸缩（Auto Scaling，以下简称AS）是根据用户的业务需求，通过设置伸缩规则来自动增加/缩减业务资源

华为云提供了AS服务端SDK，您可以直接集成服务端SDK来调用AS的相关API，从而实现对AS的快速操作。
该示例展示了如何通过java版SDK创建伸缩配置。

## 2、前置条件

1. 获取华为云开发工具包（SDK），您也可以查看安装JAVA SDK。具体请参见[SDK概述_弹性伸缩 AS_SDK参考_华为云 (huaweicloud.com)](https://support.huaweicloud.com/sdkreference-as/as_sdk_0101.html)
2. 要使用华为云 Java SDK，您需要拥有华为云账号以及该账号对应的 Access Key（AK）和 Secret Access Key（SK）。请在华为云控制台“我的凭证 > 访问密钥”页面上创建和查看您的AK/SK。具体请参见 [访问密钥](https://support.huaweicloud.com/usermanual-ca/zh-cn_topic_0046606340.html) 。
3. 华为云 Java SDK 支持 **Java JDK 1.8** 及其以上版本。

## 3、SDK获取和安装

您可以通过Maven配置所依赖的主机迁移服务SDK

```xml
<dependency>
    <groupId>com.huaweicloud.sdk</groupId>
    <artifactId>huaweicloud-sdk-as</artifactId>
    <version>3.1.46</version>
</dependency>
```

## 4、示例代码

创建伸缩配置示例代码如下：

```java
import com.huaweicloud.sdk.as.v1.AsClient;
import com.huaweicloud.sdk.as.v1.model.CreateScalingConfigOption;
import com.huaweicloud.sdk.as.v1.model.CreateScalingConfigRequest;
import com.huaweicloud.sdk.as.v1.model.CreateScalingConfigResponse;
import com.huaweicloud.sdk.as.v1.model.DiskInfo;
import com.huaweicloud.sdk.as.v1.model.InstanceConfig;
import com.huaweicloud.sdk.as.v1.model.SecurityGroups;
import com.huaweicloud.sdk.as.v1.region.AsRegion;
import com.huaweicloud.sdk.core.auth.BasicCredentials;
import com.huaweicloud.sdk.core.auth.ICredential;
import com.huaweicloud.sdk.core.exception.ConnectionException;
import com.huaweicloud.sdk.core.exception.RequestTimeoutException;
import com.huaweicloud.sdk.core.exception.ServiceResponseException;

import java.util.ArrayList;
import java.util.List;

public class CreateScalingConfigSolution {

    public static void main(String[] args) {
        ICredential auth = initCredential();

        AsClient client = initAsClient(auth);

        CreateScalingConfigRequest request = initCreateScalingConfigRequest();

        try {
            CreateScalingConfigResponse response = client.createScalingConfig(request);
            System.out.println(response.toString());
        } catch (ConnectionException e) {
            e.printStackTrace();
        } catch (RequestTimeoutException e) {
            e.printStackTrace();
        } catch (ServiceResponseException e) {
            e.printStackTrace();
            System.out.println(e.getHttpStatusCode());
            System.out.println(e.getRequestId());
            System.out.println(e.getErrorCode());
            System.out.println(e.getErrorMsg());
        }
    }

    private static AsClient initAsClient(ICredential auth) {
        return AsClient.newBuilder().withCredential(auth).withRegion(AsRegion.valueOf("${YOUR region}")).build();
    }

    private static ICredential initCredential() {
        String ak = "<YOUR AK>";
        String sk = "<YOUR SK>";

        return new BasicCredentials().withAk(ak).withSk(sk);
    }

    private static CreateScalingConfigRequest initCreateScalingConfigRequest() {
        CreateScalingConfigRequest request = new CreateScalingConfigRequest();
        CreateScalingConfigOption body = initCreateScalingConfigOption();
        request.withBody(body);
        return request;
    }

    private static CreateScalingConfigOption initCreateScalingConfigOption() {
        CreateScalingConfigOption body = new CreateScalingConfigOption();
        body.setScalingConfigurationName("${scaling config name}");
        InstanceConfig instanceConfig = initInstanceConfig();
        body.setInstanceConfig(instanceConfig);
        return body;
    }

    private static InstanceConfig initInstanceConfig() {
        //  详细各参数说明详见 https://console.huaweicloud.com/apiexplorer/#/openapi/AS/sdk?api=CreateScalingConfig

        InstanceConfig instanceConfig = new InstanceConfig();

        // 机器规格，多种规格逗号分割
        instanceConfig.setFlavorRef("${flavor list}");

        // 镜像ID
        instanceConfig.setImageRef("${image id}");

        // 磁盘组信息，系统盘必选，数据盘可选
        List<DiskInfo> disks = new ArrayList<>();
        instanceConfig.setDisk(disks);

        // 安全组
        List<SecurityGroups> securityGroups = new ArrayList<>();
        instanceConfig.setSecurityGroups(securityGroups);

        return instanceConfig;
    }
}
```

## 5、运行结果

```json
{"scaling_configuration_id":"3be6920f-46e2-4c2d-b057-24e0c73d378e"}
```
