Для этого необходимо объявить список `bytes` или `UploadFile`:

Вы получите, как и было объявлено, список `list` из `bytes` или `UploadFile`.

### 加入回呼 router { #add-the-callback-router }

此時你已經在先前建立的回呼 router 中，擁有所需的回呼「路徑操作（們）」（也就是「外部開發者」應該在「外部 API」中實作的那些）。

現在在「你的 API 的路徑操作裝飾器」中使用參數 `callbacks`，將該回呼 router 的屬性 `.routes`（實際上就是一個由路由／「路徑操作」所組成的 `list`）傳入：

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[33] *}

/// tip

注意你傳給 `callback=` 的不是整個 router 本身（`invoices_callback_router`），而是它的屬性 `.routes`，也就是 `invoices_callback_router.routes`。

///

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

/// tip | 提示

触发 `HTTPException` 时，可以用参数 `detail` 传递任何能转换为 JSON 的值，不仅限于 `str`。

还支持传递 `dict`、`list` 等数据结构。

**FastAPI** 能自动处理这些数据，并将之转换为 JSON。

## 添加自定义响应头 { #add-custom-headers }

有些场景下要为 HTTP 错误添加自定义响应头。例如，出于某些类型的安全需要。

一般情况下你可能不会在代码中直接使用它。

但在某些高级场景中需要时，你可以添加自定义响应头：
