これは次と同等です:

```Python

```

新しい `AsyncClient` では async/await を使っている点に注意してください。リクエストは非同期です。

> Requests est l'un des packages Python les plus téléchargés de tous les temps

La façon dont vous l'utilisez est très simple. Par exemple, pour faire une requête `GET`, vous devez écrire :

```Python
response = requests.get("http://example.com/some/url")
```

L’opération de chemin d'accès correspondante dans **FastAPI** pourrait ressembler à ceci :

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

labels.start=Start
labels.loginRequired=Login Required
labels.loginLink=Show Login Link
labels.threadName=Thread Name
labels.url=URL
labels.userFavorite=Favorite Log
labels.userInfo=User Info
labels.webApiJson=JSON Response
labels.webConfigName=Web Crawl Config Name
labels.allLanguages=All Languages
labels.dictId=Dictionary ID
labels.docId=Document ID
labels.endTime=End Time
labels.hq=hq
labels.inputs=Inputs

     *
     * This does not provide any actual downgrade protection if SMB1 is allowed.
     *
     * It will also break connections with SMB2 servers that do not properly sign error responses.
     *
     * @return whether to enforce the use of secure negotiation.
     */
    boolean isRequireSecureNegotiate();

    /**
     * Enable port 139 failover
     *

Для этого используйте стандартный `list` в Python:

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## Ответ с произвольным `dict` { #response-with-arbitrary-dict }

Вы также можете объявить HTTP-ответ, используя обычный произвольный `dict`, объявив только тип ключей и значений, без использования Pydantic-модели.

{* ../../docs_src/separate_openapi_schemas/tutorial001_py310.py hl[19] *}

...`description`에 기본값이 있기 때문에, 그 필드에 대해 **아무것도 반환하지 않더라도** 여전히 그 **기본값**이 들어가게 됩니다.

### 출력 응답 데이터용 모델 { #model-for-output-response-data }

문서에서 직접 동작시켜 응답을 확인해 보면, 코드가 `description` 필드 중 하나에 아무것도 추가하지 않았더라도 JSON 응답에는 기본값(`null`)이 포함되어 있습니다:

<div class="screenshot">
<img src="/img/tutorial/separate-openapi-schemas/image02.png">
</div>

Da mesma forma, você pode declarar respostas de listas de objetos.

Para isso, use o padrão Python `list`:

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## Resposta com `dict` arbitrário { #response-with-arbitrary-dict }

Você também pode declarar uma resposta usando um simples `dict` arbitrário, declarando apenas o tipo das chaves e valores, sem usar um modelo Pydantic.

        // Test throwing and catching the exception with cause
        String expectedMessage = "SAML assertion validation failed";
        Exception expectedCause = new IllegalStateException("Invalid SAML response");

        try {
            throw new SsoProcessException(expectedMessage, expectedCause);
        } catch (SsoProcessException e) {
            assertEquals(expectedMessage, e.getMessage());
