Overview

Package restapi Composing authorizations

This sample API demonstrates how to compose several authentication schemes
and configure complex security requirements for your operations.

This API simulates a very simple market place with customers and resellers
of items.

Personas:
  - as a first time user, I want to see all items on sales
  - as a registered customer, I want to post orders for items and
    consult my past orders
  - as a registered reseller, I want to see all pending orders on the items
    I am selling on the market place
  - as a reseller managing my own inventories, I want to post replenishment orders for the items I provide
  - as a register user, I want to consult my personal account infos

The situation we defined on the authentication side is as follows:
  - every known user is authenticated using a basic token
  - resellers are authenticated using API keys - we let the option to authenticate using a header or query param
  - any registered user (customer or reseller) will add a signed JWT to access more API endpoints

Obviously, there are several ways to achieve the same result. We just wanted to demonstrate here how
security requirements may compose several schemes.

Note that we used the "OAuth2" declaration here but don't implement a real
OAuth2 workflow: our intend here is just to be able to extract scopes from a passed JWT token (the
only way to manipulate scoped authorizers with Swagger 2.0 is to declare them with type "oauth2").
