Now you can start your app and go to [http://127.0.0.1:8000/docs](http://127.0.0.1:8000/docs).

You will see your docs have the normal *path operations* and now also some **webhooks**:

Verás que tu documentación tiene las *path operations* normales y ahora también algunos **webhooks**:

Une fois que vous allez sur [http://127.0.0.1:8000/redoc](http://127.0.0.1:8000/redoc), vous verrez que vous utilisez votre logo personnalisé (dans cet exemple, le logo de **FastAPI**) :

**FastAPI**는 요청에서 받은 **헤더**에서 **각 필드**에 대한 데이터를 **추출**하고 정의한 Pydantic 모델을 줍니다.

## 문서 확인하기 { #check-the-docs }

문서 UI `/docs`에서 필요한 헤더를 볼 수 있습니다:

<div class="screenshot">
<img src="/img/tutorial/header-param-models/image01.png">
</div>

## 추가 헤더 금지하기 { #forbid-extra-headers }

일부 특별한 사용 사례(흔하지는 않겠지만)에서는 수신하려는 헤더를 **제한**할 수 있습니다.

Pydantic의 모델 구성을 사용하여 추가(`extra`) 필드를 금지(`forbid`)할 수 있습니다:

Vous verrez que votre documentation contient les chemins d'accès habituels et désormais aussi des webhooks :

{* ../../docs_src/json_base64_bytes/tutorial001_py310.py ln[1:9,29:35] hl[9] *}

查看 `/docs` 时，你会看到字段 `data` 期望接收 base64 编码的字节：

</div>

你可以发送如下请求：

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | 提示

`aGVsbG8=` 是 `hello` 的 base64 编码。
