Cookies will never be used when generating a fiber server

[nikitaRykhlov]

The version of oapi-codegen you're using - v2.1.0

The YAML configuration file you're using:

package: openapi
generate:
  fiber-server: true
  models: true
output: server_interface_gen.go

The OpenAPI spec you're using:

openapi: "3.0.0"
info:
  version: 1.0.0
  title: Minimal ping API server
paths:
  /ping:
    get:
      parameters:
        - in: cookie
          name: some_name
          required: true
          schema:
            type: string
      responses:
        '200':
          description: pet response
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/Pong'
components:
  schemas:
    # base types
    Pong:
      type: object
      required:
        - ping
      properties:
        ping:
          type: string
          example: pong

What problem you're seeing:

Here you can see that the parameter received from the cookie will simply not be used.

// GetPing operation middleware
func (siw *ServerInterfaceWrapper) GetPing(c *fiber.Ctx) error {

	var err error

	// Parameter object where we will unmarshal all parameters from the context
	var params GetPingParams

	var cookie string

	if cookie = c.Cookies("some_name"); cookie == "" {
		var value string
		err = runtime.BindStyledParameterWithOptions("simple", "some_name", cookie, &value, runtime.BindStyledParameterOptions{Explode: true, Required: true})
		if err != nil {
			return fiber.NewError(fiber.StatusBadRequest, fmt.Errorf("Invalid format for parameter some_name: %w", err).Error())
		}
		params.SomeName = value

	} else {
		err = fmt.Errorf("Query argument some_name is required, but not found")
		return fiber.NewError(fiber.StatusBadRequest, err.Error())
	}

	return siw.Handler.GetPing(c, params)
}

What the expected behaviour is:

I expect the value obtained from the cookie to be passed to the request handler.

What version of Go you're using:
