Si vous allez sur les `/docs`, vous verrez que le champ `data` attend des octets encodés en base64 :

<div class="screenshot">
<img src="/img/tutorial/json-base64-bytes/image01.png">
</div>

Vous pourriez envoyer une requête comme :

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

/// tip | Astuce

`aGVsbG8=` est l'encodage base64 de `hello`.

FastAPI 會從請求的標頭為每個欄位擷取資料，並交給你已定義的 Pydantic 模型實例。

## 檢視文件 { #check-the-docs }

你可以在 `/docs` 的文件介面看到所需的標頭：

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

## 禁止額外標頭 { #forbid-extra-headers }

在某些特殊情境（可能不常見）下，你可能想限制允許接收的標頭。

你可以使用 Pydantic 的模型設定來 `forbid` 任何 `extra` 欄位：
