FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid
* **Document** the parameter in the OpenAPI schema *path operation* (so it will show up in the **automatic docs UI**)

## Alternative (old): `Query` as the default value { #alternative-old-query-as-the-default-value }

For example, to declare a header of `X-Token` that can appear more than once, you can write:

{* ../../docs_src/header_params/tutorial003_an_py310.py hl[9] *}

If you communicate with that *path operation* sending two HTTP headers like:

```
X-Token: foo
X-Token: bar
```

The response would be like:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## まとめ { #recap }

リクエストが単一のボディしか持てない場合でも、*path operation function*に複数のボディパラメータを追加することができます。

しかし、**FastAPI** はそれを処理し、関数内の正しいデータを与え、*path operation*内の正しいスキーマを検証し、文書化します。

また、ボディの一部として受け取る単数値を宣言することもできます。
