SDK的使用方法

上次更新时间: 2024/06/27

以下为SDK使用的实际示例 (以 runInstances 与 describeInstances 为例)
案例说明：申请云服务器，并持续追踪订单状态直到云服务器完成供装

package chttl.cloud.hws;

import java.util.List;

import chttl.cloud.hws.auth.HwsBasicCredential;
import chttl.cloud.hws.auth.HwsCredential;
import chttl.cloud.hws.exception.HiCloudClientException;
import chttl.cloud.hws.exception.HiCloudServerException;
import chttl.cloud.hws.services.caas.VirtualMachineService;
import chttl.cloud.hws.services.caas.model.DescribeInstancesRequest;
import chttl.cloud.hws.services.caas.model.DescribeInstancesResponse;
import chttl.cloud.hws.services.caas.model.RunInstancesRequest;
import chttl.cloud.hws.services.caas.model.RunInstancesResponse;
import chttl.cloud.hws.services.caas.model.VirtualMachineEntry;

public class ExampleApp
{
	public static void main(String[] args)
			throws HiCloudClientException, HiCloudServerException
	{
		// 添加凭证
		String accessKey = "U0U0MU5UQXhNREF3TVRFek5qSTVPRFkxTURneU1UWT0";
		String secretKey = "WWpJNU16a3pOV1JsWWpNeU5HVXdOMkkxTURNd1lUbG1OMlEwTXpSaFptST0";
		HwsCredential credential = new HwsBasicCredential(accessKey, secretKey);

		// 添加凭证(使用Property文件)
		// HwsCredential credential = new HwsPropertyCredential();

		// 创建Client End
		HiCloudWebServiceClient client = new HiCloudWebServiceClient("hws.hicloud.hinet.net", credential);

		// 若使用Proxy Server，可通过以下方式设置
		client.getConfiguration().setProxyServerIp("proxy.cht.com.tw");
		client.getConfiguration().setProxyServerPort(8080);

		// 创建VM Service Proxy，负责代理处理参数传递与数据验证
		VirtualMachineService serviceProxy = client.newServiceProxy(VirtualMachineService.class);

		// 步骤1:添加VM
		// 添加Run Instance Request
		RunInstancesRequest request = new RunInstancesRequest();
		request.setImageId("hi-cuium8up");
		request.setCount(1);
		request.setInstanceName("Test HA");
		request.setMonitoringEnabled(false);
		request.setInstanceType("HC1.S.WIN");
		request.setRegionId("region-tw-1");

		// 呼叫CaaS / CVPC API创建VM並返回RunInstancesResponse
		RunInstancesResponse runInstancesResult = serviceProxy.runInstances(request);
		// 顯示RunInstancesResponse結果
		System.out.println(runInstancesResult);

		// 步驟2:查詢云服务器資訊
		// 添加Describe Instance Request
		DescribeInstancesRequest describeRequest = new DescribeInstancesRequest();
		// 根据添加RunInstance返回的uuid查询，云服务器订单状态
		describeRequest.setOrderUuid(runInstancesResult.getOrderUuidList());

		boolean isProvisionFinished = false;
		// 持续查询云服务器信息，直到云服务器供装完毕
		while (!isProvisionFinished)
		{
			// 呼叫CaaS / CVPC API查詢VM並返回DescribeInstancesResponse
			DescribeInstancesResponse describeInstancesResult = serviceProxy.describeInstances(describeRequest);
			// 显示VM订单状态
			System.out.println(describeInstancesResult);

			List<VirtualMachineEntry> instances = describeInstancesResult.getInstanceList();
			for (VirtualMachineEntry instance : instances)
			{
				if (!instance.getProvisionStatus().equals("provisioning"))
				{
					isProvisionFinished = true;
				}
			}

			try
			{
				Thread.sleep(5000);
			}
			catch (InterruptedException e)
			{
				e.printStackTrace();
			}
		}
	}
}
