# カスタムレスポンス - HTML、ストリーム、ファイル、その他のレスポンス

デフォルトでは、**FastAPI** は `JSONResponse` を使ってレスポンスを返します。

[レスポンスを直接返す](response-directly.md){.internal-link target=_blank}で見たように、 `Response` を直接返すことでこの挙動をオーバーライドできます。

しかし、`Response` を直接返すと、データは自動的に変換されず、ドキュメントも自動生成されません (例えば、生成されるOpenAPIの一部としてHTTPヘッダー `Content-Type` に特定の「メディアタイプ」を含めるなど) 。

しかし、*path operationデコレータ* に、使いたい `Response` を宣言することもできます。

*path operation関数* から返されるコンテンツは、その `Response` に含まれます。

# 사용자 정의 응답 - HTML, Stream, 파일, 기타

기본적으로, **FastAPI** 응답을 `JSONResponse`를 사용하여 반환합니다.

이를 재정의 하려면 [응답을 직접 반환하기](response-directly.md){.internal-link target=_blank}에서 본 것처럼 `Response`를 직접 반환하면 됩니다.

그러나 `Response` (또는 `JSONResponse`와 같은 하위 클래스)를 직접 반환하면, 데이터가 자동으로 변환되지 않으며 (심지어 `response_model`을 선언했더라도), 문서화가 자동으로 생성되지 않습니다(예를 들어, 생성된 OpenAPI의 일부로 HTTP 헤더 `Content-Type`에 특정 "미디어 타입"을 포함하는 경우).

            if (mojoDescriptor.isV4Api()) {
                // For Maven 4 plugins, register a service so that they can be directly injected into plugins
                Map<Class<? extends Service>, Supplier<? extends Service>> services = sessionV4.getAllServices();

            // First read - should initialize cache
            assertEquals("initial.value", wrapperProps.getProperty("initial.key"));

            // Simulate external change by directly calling setProperties (another WrapperProperties instance)
            Properties externalProps = new Properties();
            externalProps.setProperty("initial.key", "externally.modified");

So, you import `Query`, which is a function. And when you call it, it returns an instance of a class also named `Query`.

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

That way you can use your normal editor and coding tools without having to add custom configurations to disregard those errors.

            if (includeModules) {
                for (String module : project.getModules()) {
                    File modulePom = new File(pom.getParentFile(), module);
                    if (modulePom.isDirectory()) {
                        modulePom = new File(modulePom, "pom.xml");
                    }
                    projects.add(projectBuilder.build(modulePom, configuration).getProject());
                }

## Use the model { #use-the-model }

Inside of the function, you can access all the attributes of the model object directly:

{* ../../docs_src/body/tutorial002_py310.py *}

## Request body + path parameters { #request-body-path-parameters }

You can declare path parameters and request body at the same time.

Try to be as specific and objective as possible, avoid generalizations.

For conversations that are more difficult, for example to reject a PR, you can ask me (@tiangolo) to handle it directly.

## Edit PR Titles

* Edit the PR title to start with an emoji from <a href="https://gitmoji.dev/" class="external-link" target="_blank">gitmoji</a>.

### Retorne uma Response diretamente { #return-a-response-directly }

O caso mais comum seria [retornar uma Response diretamente, conforme explicado posteriormente na documentação avançada](../advanced/response-directly.md){.internal-link target=_blank}.

{* ../../docs_src/response_model/tutorial003_02_py39.py hl[8,10:11] *}

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[9] *}

In this case, **FastAPI** won't ever touch or care about `__init__`, we will use it directly in our code.

## Create an instance { #create-an-instance }

We could create an instance of this class with:

{* ../../docs_src/dependencies/tutorial011_an_py39.py hl[18] *}
