接口说明

• 请求参数的作用类似于一个过滤器，过滤器为逻辑与（AND）关系。如果某一参数为空，则过滤器不起作用。但是参数InstanceIds如果是一个空JSON数组，则视为该过滤器有效，且返回空。
• 如果您使用的是RAM用户账号或者RAM角色，当用户或者角色缺乏接口权限时，将会返回空列表。您可以在请求中加入DryRun参数，判断是否因权限问题导致的空列表现象。
• 通过阿里云CLI调用API时，不同数据类型的请求参数取值必须遵循格式要求。更多信息，请参见CLI参数格式说明。
• 支持以下两种方式查看返回数据：
  • 方式一：通过NextToken设置查询凭证（Token），其取值是上一次调用DescribeInstances返回的NextToken参数值，再通过MaxResults设置单页查询的最大条目数。

  • 方式二：通过PageSize设置单页返回的条目数，再通过PageNumber设置页码。

    以上两种方式只能任选其中之一。当返回的条目数较多时，推荐使用方式一。如果设置了NextToken，则请求参数PageSize和PageNumber将失效。
