第一步是停用自動文件，因為預設會使用預設的 CDN。

要停用它們，建立 `FastAPI` 應用時把相關 URL 設為 `None`：

{* ../../docs_src/custom_docs_ui/tutorial001_py310.py hl[8] *}

### 加入自訂文件 { #include-the-custom-docs }

現在你可以為自訂文件建立「路徑操作（path operation）」。

你可以重用 FastAPI 的內部函式來建立文件的 HTML 頁面，並傳入所需參數：

* `openapi_url`：文件 HTML 頁面用來取得你 API 的 OpenAPI schema 的 URL。可使用屬性 `app.openapi_url`。
* `title`：你的 API 標題。

/// info | 정보

"경로"는 일반적으로 "엔드포인트" 또는 "라우트"라고도 불립니다.

///

API를 설계할 때 "경로"는 "관심사"와 "리소스"를 분리하기 위한 주요한 방법입니다.

#### 작동 { #operation }

"작동(Operation)"은 HTTP "메소드" 중 하나를 나타냅니다.

다음 중 하나이며:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...흔히 사용되지 않는 것들도 있습니다:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

HTTP 프로토콜에서는 이러한 "메소드"를 하나(또는 이상) 사용하여 각 경로와 통신할 수 있습니다.

# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```
