You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

### Use-o { #use-it }

Agora você pode passar esse `oauth2_scheme` em uma dependência com `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

Essa dependência fornecerá uma `str` que é atribuída ao parâmetro `token` da função de operação de rota.

O **FastAPI** saberá que pode usar essa dependência para definir um "esquema de segurança" no esquema OpenAPI (e na documentação automática da API).

### Úsalo { #use-it }

Ahora puedes pasar ese `oauth2_scheme` en una dependencia con `Depends`.

{* ../../docs_src/security/tutorial001_an_py39.py hl[12] *}

Esta dependencia proporcionará un `str` que se asigna al parámetro `token` de la *path operation function*.

**FastAPI** sabrá que puede usar esta dependencia para definir un "security scheme" en el esquema OpenAPI (y en los docs automáticos del API).
