如何在OpenAPI（Swagger）中定义一个接受任意对象数组的参数？

Question

在我的OpenAPI规范中，是否有可能将参数定义为对象，而不必定义其属性（匿名对象）？更具体地说，我希望我的应用编程接口能够接受这些匿名对象的数组。

这是我所拥有的，但是我在斯瓦格编辑器中得到了一个“无效参数定义”错误。

swagger: '2.0'

  title: Test API
  description: Test
  version: "1.0.0"
host: api.example.com
schemes:
  - https
basePath: /v1
produces:
  - application/json
paths:
  /api/example:
    post:
      description: Endpoint description
      parameters:
        - name: param1
          in: query
          description: param1
          required: true
          type: array
          items:
            type: object
        - name: param2
          in: query
          description: param2
          required: true
          type: string
      responses:
        200:
          description: error response
          schema:
            type: object
        default:
          description: Unexpected error
          schema:
            $ref: '#/definitions/Error'
definitions:
  Error:
    type: object
    properties:
      code:
        type: integer
        format: int32
      message:
        type: string
      fields:
        type: string

以下是错误：

Helen指出的问题是，我将参数指定为查询参数，而不是请求主体。以下是我想要的：
