若你所在的國家限制部分網址，這會很有用。

### 停用自動產生的文件 { #disable-the-automatic-docs }

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。
