Custom validation for Request data

[vishal1]

Hi,

My nodejs app is using swagger-tools middleware with express which works fine with most of my service's contracts defined in the swagger spec.

I have a requirement where a request's body object's (json payload) some part is dynamic. So, I can't validate it using the spec. I am thinking of using express validation middleware for any custom validation. Is that a sensible approach or can I use swagger middleware for custom validation as well?

Thankyou

Can you elaborate? Swagger should allow for some level of dynamic even if it's just having an open schema for the dynamic part(s).

Hello, thankyou for the response. Based on the below example I would like vehicleType inside vehicle definition to be of type either car or bike:

paths:
  /vehicle:
    post:
      parameters:
      - $ref: '#/parameters/vehicle'
      responses:
        200:
          description: Success!
parameters:
  vehicle:
    name: vehicle
    in: body
    required: true
    schema: 
      $ref: "#/definitions/vehicle"

definitions:
  vehicle:
    type: object
    properties:
      id:
        type: string
      name:
        type: string
      vehicleType:
        type: object
        anyOf:
        - $ref: "#/definitions/car"
        - $ref: "#/definitions/bike"
        
  car:
    type: object
    properties:
      model:
        type: string
      type:
        type: string
        enum:
          - Saloon
          - Estate

  bike:
    type: object
    properties:
      model:
        type: string
      type:
        type: string
        enum:
          - Scooter
          - Sport

Sorry for the indentation problem above. Not sure how to paste it indented.
