Swagger array of objects

Question

I am having some issues with swagger: I have an array of objects (address) described in this way in the .yaml file:

Address:
  properties:
    street:
      type: string
    city:
      type: string
    state:
      type: string
    country:
      type: string

and this is the other yaml file with the definitions of the API (address is a params):

 - name: addresses
   in: formData
   description: List of adresses of the user. The first one is the default one.
   type: array
   items:
     $ref: '#/definitions/Address'

And this is the text I put in the swagger UI:

[
  {
    "street": "Bond street",
    "city": "Torino",
    "state": "Italy",
    "country": "Italy"
  }
]

but in node.js, if I print what I receive:

{"addresses":["["," {"," \"street\": \"Bond street\","," \"city\": \"Torino\","," \"state\": \"Italy\","," \"country\": \"Italy\""," }","]"]}

And I get a parsing error... There are some extra [ and ". It seems that swagger parse it as string (?)

Solution

To send JSON data, you need to use use an in: body parameter (not in: formData) and specify that the operation consumes application/json. formData parameters are used for operations that consume application/x-www-form-urlencoded or multipart/form-data.

paths:
  /something:
     post:
       consumes:
         - application/json
       parameters:
         - in: body
           name: addresses
           required: true
           schema:
             type: array
             items:
               $ref: "#/definitions/Address"  # if "Address" is in the same file
               # or
               # $ref: "anotherfile.yaml#/definitions/Address"  # if "Address" is in another file

Thank you for all the suggestions. But something is not working anyway. I changed the in:body but still

Define "is not working". Does Swagger UI render this incorrectly? Does you backend receive incorrect data? The more details the better.

yes, sorry for the short answer yesterday. Still receiving wrong data in my BE.

Hello, In the end I was able to fix it. I didn't notice the change in schema. Thank you.
