How to define an example request body containing an array of complex objects in Swagger?

Question

I am trying to write the Swagger spec for a service that posts an array of objects as request body. I would like the user to be able to test the service with a specific set of multiple different complex objects in the array as the default sample inputs.

So far I have the following code defining the service and complex object:

paths:
    /myService
        post:
            summary: test 123
            description: test 123
            parameters:
                - name: bodyParamsObject
                  description: 'Object containing any / all params in the body'
                  in: body
                  required: true
                  schema:
                    properties:
                        data:
                            $ref: '#/definitions/myInputArray'
            responses:
                200:
                    description: OK
                    schema: myOutputArray

definitions:
    myInputArray:
        type: array
        items:
            $ref: '#/definitions/myComplexObject'

    myOutputArray:
        type: array
        items:
            $ref: '#/definitions/myComplexObject'

    myComplexObject:
        type: object
        properties:
            description:
            type: string
            example: 'Example Item'     
        size:
            example: 552
            type: integer
            format: int32
        hasAdditionalProperties:
            type: boolean
            example: true

The output array is coming back correctly, but there is only one item in the model schema.

How can I make the sample request body contain multiple different items in the array?

Answer 1

I was able to solve this by using the example property on the object definition and filling it with the array in json.

definitions:
    myInputArray:
        type: array
        items:
            $ref: '#/definitions/myComplexObject'
        example: [
                    {
                        "description": "Example Item 1",
                        "hasAdditionalProperties": true,
                        "size": 750,
                    },
                    {
                        "description": "Another example",
                        "hasAdditionalProperties": false,
                        "size": -22,
                    },                                
                    {
                        "description": "Last one",
                        "hasAdditionalProperties": true,
                        "size": 0,
                    }
                ]

    myComplexObject:
        type: object
        properties:
            description:
            type: string
            example: 'Example Item'     
        size:
            example: 552
            type: integer
            format: int32
        hasAdditionalProperties:
            type: boolean
            example: true
