I would like to define an endpoint using swagger 2.0 that consumes application/x-www-form-urlencoded .

The passed parameters can have different names and be of different types. How should I define this in the yaml? I am playing with this the whole day and cannot figure it out. Everything I've found in the documentation is that I have to use 'parameters' but I don't know how to resolve the random number of parameters and their names.

As an example, I would like both queries to work:

First curl:

curl --location --request POST 'https://localhost:8080/contact/123456789' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'name=random value' \
--data-urlencode 'Email=randomValue' \
--data-urlencode 'address=random' \
--data-urlencode 'surname2=123' \
--data-urlencode 'surname=random'

Second curl:

curl --location --request POST 'https://localhost:8080/contact/123456789' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--data-urlencode 'car=bmw' \
--data-urlencode 'house=small'

And invalid YAML - but I cannot figure out how to solve my issue.

paths:
  /contact/{phone}:
    post:
      consumes:
        - application/x-www-form-urlencoded
      produces:
        - application/json
      parameters:
        - in: formData
          name: form_data
          description: Body for submitting the contact
          required: false
          type: string
        - in: path
          name: phone
          description: phone number
          required: true
          type: string

Could you assist me?
