use of com.tencentcloudapi.cvm.v20170312.CvmClient in project tencentcloud-sdk-java by TencentCloud.

the class DescribeInstances method main.

        DescribeInstancesRequest req = new DescribeInstancesRequest();
        // 填充请求参数,这里request对象的成员变量即对应接口的入参
        // 你可以通过官网接口文档或跳转到request对象的定义处查看请求参数的定义
        // 创建Filter对象, 以zone的维度来查询cvm实例
        Filter respFilter = new Filter();
        respFilter.setName("zone");
        respFilter.setValues(new String[] { "ap-shanghai-1", "ap-shanghai-2" });

        req.setFilters(new Filter[] { respFilter });
        // 这里还支持以标准json格式的string来赋值请求参数的方式。下面的代码跟上面的参数赋值是等效的

        // 返回的resp是一个DescribeInstancesResponse类的实例，与请求对象对应
        DescribeInstancesResponse resp = client.DescribeInstances(req);
        // 输出json格式的字符串回包
        System.out.println(DescribeInstancesResponse.toJsonString(resp));
        // 也可以取出单个值。
        // 你可以通过官网接口文档或跳转到response对象的定义处查看返回字段的定义
        System.out.println(resp.getTotalCount());
