!!! warning
    Extra keys passed to `Field` will also be present in the resulting OpenAPI schema for your application.
    As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## Recap

In this section we'll see how to use other middlewares.

## Adding ASGI middlewares

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

A middleware doesn't have to be made for FastAPI or Starlette to work, as long as it follows the ASGI spec.

    * **Standards-basiert**: Basierend auf (und vollständig kompatibel mit) den offenen Standards für APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> und <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.

    * **Robusto**: Tenha código pronto para produção. Com documentação interativa automática.
    * **Baseado em Padrões**: Baseado em (e completamente compatível com) padrões abertos para APIs: <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> e <a href="http://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.

    * **Basé sur des normes** : Basé sur (et totalement compatible avec) les normes ouvertes pour les APIs : <a href="https://github.com/OAI/OpenAPI-Specification" class="external-link" target="_blank">OpenAPI</a> et <a href="https://json-schema.org/" class="external-link" target="_blank">JSON Schema</a>.
