/// tip | Astuce

Vous vous souvenez peut-être que les corps de requête sont également déclarés avec des modèles Pydantic.

Ici, **FastAPI** ne s'y trompera pas car vous utilisez `Depends`.

///

/// check | Vérifications

La manière dont ce système de dépendances est conçu nous permet d'avoir différentes dépendances (différents « dependables ») qui retournent toutes un modèle `User`.

`callback=` içine router'ın kendisini (`invoices_callback_router`) değil, `invoices_callback_router.routes` şeklinde `.routes` attribute'unu verdiğinize dikkat edin.

/// info | 정보

`response_description`은 구체적으로 응답을 지칭하며, `description`은 일반적인 *경로 처리*를 지칭합니다.

///

/// check | 확인

OpenAPI는 각 *경로 처리*가 응답에 관한 설명을 요구할 것을 명시합니다.

따라서, 응답에 관한 설명을 제공하지 않으면, **FastAPI**가 "Successful response" 중 하나를 자동으로 생성합니다.

* `limit=10`：因為那是預設值

## 選用參數 { #optional-parameters }

同樣地，你可以將預設值設為 `None` 來宣告選用的查詢參數：

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

在這種情況下，函式參數 `q` 為選用，且預設為 `None`。

/// check | 注意

另外請注意，FastAPI 能辨識出路徑參數 `item_id` 是路徑參數，而 `q` 不是，因此 `q` 會被當作查詢參數。

///

## 查詢參數型別轉換 { #query-parameter-type-conversion }

你也可以宣告 `bool` 型別，值會被自動轉換：

{* ../../docs_src/query_params/tutorial002_py310.py hl[7] *}

Dans ce cas, le paramètre de fonction `q` sera optionnel et vaudra `None` par défaut.

/// check | Vérifications

Notez également que **FastAPI** est suffisamment intelligent pour remarquer que le paramètre de chemin `item_id` est un paramètre de chemin et que `q` ne l'est pas, c'est donc un paramètre de requête.

Quando você tentar abrir a URL pela primeira vez (ou clicar no botão "Executar" na documentação) o navegador vai pedir pelo seu usuário e senha:

## Verifique o usuário { #check-the-username }

Aqui está um exemplo mais completo.

Utilize uma dependência para verificar se o usuário e a senha estão corretos.
