Example 1 with DescribeInstancesRequest

use of com.tencentcloudapi.cvm.v20170312.models.DescribeInstancesRequest 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

        // 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。
