#### Retourner des *membres d'énumération*

Vous pouvez retourner des *membres d'énumération* dans vos *fonctions de chemin*, même imbriquée dans un JSON (e.g. un `dict`).

Ils seront convertis vers leurs valeurs correspondantes (chaînes de caractères ici) avant d'être transmis au client :

```Python hl_lines="18  21  23"
{!../../docs_src/path_params/tutorial005.py!}
```

```JSON
{
  "detail": "Item not found"
}
```

/// tip

When raising an `HTTPException`, you can pass any value that can be converted to JSON as the parameter `detail`, not only `str`.

You could pass a `dict`, a `list`, etc.

They are handled automatically by **FastAPI** and converted to JSON.

///

## Add custom headers

///

### 步骤 5：返回内容

```Python hl_lines="8"
{!../../docs_src/first_steps/tutorial001.py!}
```

你可以返回一个 `dict`、`list`，像 `str`、`int` 一样的单个值，等等。

你还可以返回 Pydantic 模型（稍后你将了解更多）。

还有许多其他将会自动转换为 JSON 的对象和模型（包括 ORM 对象等）。尝试下使用你最喜欢的一种，它很有可能已经被支持。

## 总结

* 导入 `FastAPI`。
* 创建一个 `app` 实例。

### Step 5: return the content

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

You can return a `dict`, `list`, singular values as `str`, `int`, etc.

You can also return Pydantic models (you'll see more about that later).
