`async def`や通常の`def`を使用することができます。

また、通常の`def`*path operation関数*の中に`async def`を入れて依存関係を宣言したり、`async def`*path operation関数*の中に`def`を入れて依存関係を宣言したりすることなどができます。

それは重要ではありません。**FastAPI** は何をすべきかを知っています。

## Интеграция с OpenAPI

### Conversor de rota

Usando uma opção direta do Starlette você pode declarar um *parâmetro de rota* contendo uma *rota* usando uma URL como:

```
/files/{file_path:path}
```

Nesse caso, o nome do parâmetro é `file_path`, e a última parte, `:path`, diz que o parâmetro deveria coincidir com qualquer *rota*.

Então, você poderia usar ele com:

```Python hl_lines="6"
{!../../docs_src/path_params/tutorial004.py!}
