## 🗄 & 🛠️ 🩺

Es enthält `tags`, `parameters`, `requestBody`, `responses`, usw.

Dieses *Pfadoperation*-spezifische OpenAPI-Schema wird normalerweise automatisch von **FastAPI** generiert, Sie können es aber auch erweitern.

!!! tip "Tipp"
    Dies ist ein Low-Level Erweiterungspunkt.

    Wenn Sie nur zusätzliche Responses deklarieren müssen, können Sie dies bequemer mit [Zusätzliche Responses in OpenAPI](additional-responses.md){.internal-link target=_blank} tun.

It includes the `tags`, `parameters`, `requestBody`, `responses`, etc.

This *path operation*-specific OpenAPI schema is normally generated automatically by **FastAPI**, but you can also extend it.

!!! tip
    This is a low level extension point.

    If you only need to declare additional responses, a more convenient way to do it is with [Additional Responses in OpenAPI](additional-responses.md){.internal-link target=_blank}.

```

!!! warning "注意"
    上記の例のように `Response` を明示的に返す場合、それは直接返されます。

    モデルなどはシリアライズされません。

    必要なデータが含まれていることや、値が有効なJSONであること (`JSONResponse` を使う場合) を確認してください。

!!! note "技術詳細"
    `from starlette.responses import JSONResponse` を利用することもできます。

    **FastAPI** は `fastapi.responses` と同じ `starlette.responses` を、開発者の利便性のために提供しています。しかし有効なレスポンスはほとんどStarletteから来ています。 `status` についても同じです。

```

!!! note "Technical Details"
    You could also use `from starlette.requests import Request` and `from starlette.responses import JSONResponse`.

    **FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette. The same with `Request`.
