# Body - Multiple Parameters

Now that we have seen how to use `Path` and `Query`, let's see more advanced uses of request body declarations.

## Mix `Path`, `Query` and body parameters

First, of course, you can mix `Path`, `Query` and request body parameter declarations freely and **FastAPI** will know what to do.

And you can also declare body parameters as optional, by setting the default to `None`:

//// tab | Python 3.10+

///

/// tip | "Dica"

Se você quiser chamar funções `async` em seus testes além de enviar solicitações ao seu aplicativo FastAPI (por exemplo, funções de banco de dados assíncronas), dê uma olhada em [Testes assíncronos](../advanced/async-tests.md){.internal-link target=_blank} no tutorial avançado.

## Separando testes

Em uma aplicação real, você provavelmente teria seus testes em um arquivo diferente.

        <!-- Sega Genesis -->
        <match value="\x13" type="string" offset="3"/>
        <!-- Nintendo 64-->
        <match value="\x21" type="string" offset="3"/>
        <!-- GameBoy Advance -->
        <match value="\x22" type="string" offset="3"/>
        <!-- Super NES -->
        <match value="\x23" type="string" offset="3"/>
        <!-- Capcom QSound -->

   * uncommon to specify {@code concurrencyLevel(1)} in order to achieve more deterministic eviction
   * behavior.
   *
   * <p>Note that future implementations may abandon segment locking in favor of more advanced
   * concurrency controls.
   *
   * @return this {@code CacheBuilder} instance (for chaining)
   * @throws IllegalArgumentException if {@code concurrencyLevel} is nonpositive

例えば、リクエストの処理とレスポンスの生成にかかった秒数を含むカスタムヘッダー `X-Process-Time` を追加できます:

```Python hl_lines="10  12-13"
{!../../docs_src/middleware/tutorial001.py!}
```

## その他のミドルウェア

  - Attribute, add a new attribute `Key` is `policy`, `Value` is name of the `policy` on MinIO (ex: `readwrite`)
  - Add and Save

- Go to Clients
  - Click on `account`
  - Settings, set `Valid Redirect URIs` to `*`, expand `Advanced Settings` and set `Access Token Lifespan` to `1 Hours`
  - Save

- Go to Clients
  - Click on `account`
  - Mappers
  - Create
    - `Name` with any text
    - `Mapper Type` is `User Attribute`

# Réponses supplémentaires dans OpenAPI

/// warning | "Attention"

Ceci concerne un sujet plutôt avancé.

Si vous débutez avec **FastAPI**, vous n'en aurez peut-être pas besoin.

///

Vous pouvez déclarer des réponses supplémentaires, avec des codes HTTP, des types de médias, des descriptions, etc.

Ces réponses supplémentaires seront incluses dans le schéma OpenAPI, elles apparaîtront donc également dans la documentation de l'API.

# Additional Responses in OpenAPI

/// warning

This is a rather advanced topic.

If you are starting with **FastAPI**, you might not need this.

///

You can declare additional responses, with additional status codes, media types, descriptions, etc.

Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.

## Advanced options

### Change default FTP port

Default port '8021' can be changed via

```
--ftp="address=:3021"
```

### Change FTP passive port range
