## Agregando middlewares ASGI { #adding-asgi-middlewares }

Como **FastAPI** está basado en Starlette e implementa la especificación <abbr title="Asynchronous Server Gateway Interface – Interfaz de puerta de enlace de servidor asíncrona">ASGI</abbr>, puedes usar cualquier middleware ASGI.

Un middleware no tiene que estar hecho para FastAPI o Starlette para funcionar, siempre que siga la especificación ASGI.

But here's the key point.

The security and dependency injection stuff is written once.

And you can make it as complex as you want. And still, have it written only once, in a single place. With all the flexibility.

But you can have thousands of endpoints (*path operations*) using the same security system.

#### Adding 'admin' Role

- Go to Roles
  - Add new Role `admin` with Description `${role_admin}`.
  - Add this Role into compositive role named `default-roles-{realm}` - `{realm}` should be replaced with whatever realm you created from `prerequisites` section. This role is automatically trusted in the 'Service Accounts' tab.

- Check that `account` client_id has the role 'admin' assigned in the "Service Account Roles" tab.

## Declaring types { #declaring-types }

You just saw the main place to declare type hints. As function parameters.

This is also the main place you would use them with **FastAPI**.

### Simple types { #simple-types }

You can declare all the standard Python types, not only `str`.

You can use, for example:

## Développement

Au moment où j'ai commencé à créer **FastAPI** lui-même, la plupart des pièces étaient déjà en place, la conception était définie, les exigences et les outils étaient prêts, et la connaissance des normes et des spécifications était claire et fraîche.

# This avoids shell parsing issues with pipes, quotes, @, and other special characters

    * Si on n'utilisait pas FastAPI mais directement Starlette (ou un outil équivalent comme Sanic, Flask, Responder, etc) il faudrait implémenter la validation des données et la sérialisation par nous-même. Le résultat serait donc le même dans...
