Swagger 多级鉴别器OpenAPI

问候并感谢您抽出时间。 我正在使用OpenAPI编写一些ReDoc文档，但找不到一种方法来正确地进行两级继承。这就是我所拥有的：

components:
  schemas:
    Pet:
      type: object
      required:
      - pet_type
      properties:
        pet_type:
          type: string
      discriminator:
        propertyName: pet_type
        mapping:
          dogs: Dog
          cats: Cat

    Cat:
      allOf:
      - $ref: '#/components/schemas/Pet'
      - type: object
        # all other properties specific to a `Cat`
        properties:
          name:
            type: string
    Dog:
      allOf:
      - $ref: '#/components/schemas/Pet'
      - type: object
        # all other properties specific to a `Dog`
        properties:
          bark:
            type: string
          size:
            type: string
        discriminator:
          propertyName: size
          mapping:
             large: '#/components/schemas/LargeDog'
             medium: '#/components/schemas/MediumDog'
    SmallDogs:
      allOf:
      - $ref: '#/components/schemas/Dog'
      - type: object
    LargeDogs:
      allOf:
      - $ref: '#/components/schemas/Dog'
      - type: object

提前感谢。

您正在做一些奇怪的事情，或者您的示例没有充分揭示问题的本质。对于狗的大小，您不需要使用鉴别器。下面的例子

components:
  schemas:
    Pet:
      type: object
      required:
      - pet_type
      properties:
        pet_type:
          type: string
      discriminator:
        propertyName: pet_type
        mapping:
          dogs: Dog
          cats: Cat
    Cat:
      allOf:
      - $ref: '#/components/schemas/Pet'
      - type: object
        # all other properties specific to a `Cat`
        properties:
          name:
            type: string
    Dog:
      allOf:
      - $ref: '#/components/schemas/Pet'
      - type: object
        # all other properties specific to a `Dog`
        properties:
          bark:
            type: string
          size:
            type: string
            enum:
            - large
            - medium
