如何使用rswag添加Swagger show action？

gem 'rswag'

require 'rswag/api'
require 'rswag/ui'

module YourAppName
  class Application < Rails::Application
    # ...
    config.middleware.use Rswag::Api::Middleware
    config.middleware.use Rswag::Ui::Middleware
    # ...
  end
end

require 'rails_helper'

RSpec.configure do |config|
  config.swagger_root = Rails.root.to_s + '/swagger'
  config.swagger_format = :json
  config.swagger_dry_run = false
end

RSpec.describe 'Example API', type: :request do
  path '/example/{id}' do
    get 'Retrieves an example' do
      tags 'Examples'
      produces 'application/json'
      parameter name: :id, in: :path, type: :string

      response '200', 'example found' do
        schema type: :object,
               properties: {
                 id: { type: :integer },
                 name: { type: :string }
               },
               required: ['id', 'name']

        let(:id) { create(:example).id }
        run_test!
      end

      response '404', 'example not found' do
        let(:id) { 'invalid' }
        run_test!
      end
    end
  end
end
