查询ECS实例

代码示例

以下代码适用于查询中国杭州地域下公网带宽采用按流量计费、实例计费方式采用按量付费、网络类型采用专有网络VPC的ECS实例 ：

import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.profile.DefaultProfile;
import java.util.*;
import com.aliyuncs.ecs.model.v20140526.*;

public class DescribeInstances {

    public static void main(String[] args) {
        // 创建DefaultAcsClient实例并初始化。
        DefaultProfile profile = DefaultProfile.getProfile("cn-hangzhou", "<yourAccessKeyId>", "<yourAccessSecret>");
        IAcsClient client = new DefaultAcsClient(profile);

        // 创建API请求并设置参数。
        DescribeInstancesRequest request = new DescribeInstancesRequest();
        request.setRegionId("cn-hangzhou");
        request.setInstanceNetworkType("vpc");
        request.setInstanceChargeType("PostPaid");
        request.setInternetChargeType("PayByTraffic");
        request.setPageSize(10);

        try {
        // 发起请求并处理应答或异常。
            DescribeInstancesResponse response = client.getAcsResponse(request);
        for (DescribeInstancesResponse.Instance instance:response.getInstances()) 
            {
                 System.out.println(instance.getImageId());
                 System.out.println(instance.getInstanceId());
                 System.out.println(instance.getPublicIpAddress());
             }
        } catch (ServerException e) {
            e.printStackTrace();
        } catch (ClientException e) {
            System.out.println("ErrCode:" + e.getErrCode());
            System.out.println("ErrMsg:" + e.getErrMsg());
            System.out.println("RequestId:" + e.getRequestId());
        }

    }
}
