## Utilidades de **FastAPI**

FastAPI proporciona varias herramientas para cada uno de estos esquemas de seguridad en el módulo `fastapi.security` que simplifican el uso de estos mecanismos de seguridad.

En los siguientes capítulos verás cómo agregar seguridad a tu API usando esas herramientas proporcionadas por **FastAPI**.

## Преимущества **FastAPI**

Fast API предоставляет несколько инструментов для каждой из этих схем безопасности в модуле `fastapi.security`, которые упрощают использование этих механизмов безопасности.

В следующих главах вы увидите, как обезопасить свой API, используя инструменты, предоставляемые **FastAPI**.

E todas elas usarão a mesma conexão WebSocket.

## Usando `Depends` e outros

Nos endpoints WebSocket você pode importar do `fastapi` e usar:

* `Depends`
* `Security`
* `Cookie`
* `Header`
* `Path`
* `Query`

Eles funcionam da mesma forma que para outros endpoints FastAPI/*operações de rota*:
