### 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`).
* 그리고 반환해야 할 응답 선언도 있을 수 있습니다(예: `response_model=InvoiceEventReceived`).

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[14:16,19:20,26:30] *}

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### Declarando a dependência, no "dependente" { #declare-the-dependency-in-the-dependant }

Da mesma forma que você utiliza `Body`, `Query`, etc. Como parâmetros de sua *função de operação de rota*, utilize `Depends` com um novo parâmetro:

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

///

### 匯入 `Depends` { #import-depends }

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[3] *}

### 在「被依賴者」（dependant）中宣告依賴 { #declare-the-dependency-in-the-dependant }

和你在「路徑操作函式」參數上使用 `Body`、`Query` 等方式一樣，針對新參數使用 `Depends`：

{* ../../docs_src/dependencies/tutorial001_an_py310.py hl[13,18] *}

雖然你在函式參數上使用 `Depends` 的方式和 `Body`、`Query` 等相同，但 `Depends` 的運作方式有點不同。

你只需要傳給 `Depends` 一個參數。

Sie können denselben `TestClient` zum Testen von WebSockets verwenden.

Dazu verwenden Sie den `TestClient` in einer `with`-Anweisung, eine Verbindung zum WebSocket herstellend:

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

/// note | Hinweis

Weitere Informationen finden Sie in Starlettes Dokumentation zum [Testen von WebSockets](https://www.starlette.dev/testclient/#testing-websocket-sessions).

## Mettre à jour le *chemin d'accès* `/token` { #update-the-token-path-operation }

Créez un `timedelta` avec la durée d'expiration du jeton.

Créez un véritable jeton d'accès JWT et renvoyez-le.

{* ../../docs_src/security/tutorial004_an_py310.py hl[121:136] *}

Vous pouvez utiliser le même `TestClient` pour tester les WebSockets.

Pour cela, vous utilisez `TestClient` dans une instruction `with`, en vous connectant au WebSocket :

{* ../../docs_src/app_testing/tutorial002_py310.py hl[27:31] *}

Вы можете использовать тот же `TestClient` для тестирования WebSocket.

Для этого используйте `TestClient` с менеджером контекста `with`, подключаясь к WebSocket:
