本示例介绍如何使用Alibaba Cloud SDK for Java调用DescribeInstanceStatus接口获取实例状态。

前提条件

在使用本教程之前,请确保已完成以下操作:
  • 使用Alibaba Cloud SDK for Java,您需要一个阿里云账号和访问密钥(AccessKey)。 请在阿里云控制台中的AccessKey管理页面
  • 确保您已经安装了Alibaba Cloud SDK for Java,准确的SDK版本号,请参见 阿里云开发工具包(SDK)

示例代码

本文操作示例主要以代码形式体现,具体代码如下:
import com.aliyuncs.profile.DefaultProfile;
import com.aliyuncs.DefaultAcsClient;
import com.aliyuncs.IAcsClient;
import com.aliyuncs.exceptions.ClientException;
import com.aliyuncs.exceptions.ServerException;
import com.aliyuncs.ecs.model.v20140526.*;
import com.google.gson.Gson;

public class DescribeInstanceStatus {

    public static void main(String[] args) {
        DefaultProfile profile = DefaultProfile.getProfile(
                "<your-region-id>",            // 地域ID
                "<your-access-key-id>",        // 您的AccessKey ID
                "<your-access-key-secret>");  // 您的AccessKey Secret
        IAcsClient client = new DefaultAcsClient(profile);
        // 创建请求接口
        DescribeInstanceStatusRequest request = new DescribeInstanceStatusRequest();

        try {
            // 发起请求并获取返回值
            DescribeInstanceStatusResponse response = client.getAcsResponse(request);
            // 处理业务逻辑
            System.out.println(new Gson().toJson(response));
        } 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());
        }
    }
}
