### 建立一個回呼用的 `APIRouter` { #create-a-callback-apirouter }

先建立一個新的 `APIRouter`，用來放一個或多個回呼。

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### 建立回呼的「路徑操作」 { #create-the-callback-path-operation }

要建立回呼的「路徑操作」，就使用你上面建立的同一個 `APIRouter`。

它看起來就像一般的 FastAPI「路徑操作」：

* 可能需要宣告它應該接收的 body，例如 `body: InvoiceEvent`。

### 콜백 `APIRouter` 생성하기 { #create-a-callback-apirouter }

먼저 하나 이상의 콜백을 담을 새 `APIRouter`를 만듭니다.

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[1,23] *}

### 콜백 *경로 처리* 생성하기 { #create-the-callback-path-operation }

콜백 *경로 처리*를 만들려면 위에서 만든 동일한 `APIRouter`를 사용합니다.

일반적인 FastAPI *경로 처리*처럼 보일 것입니다:

* 아마도 받아야 할 body 선언이 있을 것입니다(예: `body: InvoiceEvent`).
