Sie erhalten also einen sauberen Error mit einem Statuscode `418` und dem JSON-Inhalt:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

/// note | "Technische Details"

Sie können auch `from starlette.requests import Request` und `from starlette.responses import JSONResponse` verwenden.

你从 *路径操作函数* 中返回的内容将被放在该 `Response` 中。

并且如果该 `Response` 有一个 JSON 媒体类型（`application/json`），比如使用 `JSONResponse` 或者 `UJSONResponse` 的时候，返回的数据将使用你在路径操作装饰器中声明的任何 Pydantic 的 `response_model` 自动转换（和过滤）。

/// note | "说明"

如果你使用不带有任何媒体类型的响应类，FastAPI 认为你的响应没有任何内容，所以不会在生成的OpenAPI文档中记录响应格式。

そしてもし、`Response` が、`JSONResponse` や `UJSONResponse` の場合のようにJSONメディアタイプ (`application/json`) ならば、データは *path operationデコレータ* に宣言したPydantic `response_model` により自動的に変換 (もしくはフィルタ) されます。

/// note | "備考"

メディアタイプを指定せずにレスポンスクラスを利用すると、FastAPIは何もコンテンツがないことを期待します。そのため、生成されるOpenAPIドキュメントにレスポンスフォーマットが記載されません。

## `ORJSONResponse` を使う

            data["client_id"] = form_data.client_id

    Note that for OAuth2 the scope `items:read` is a single scope in an opaque string.
    You could have custom internal logic to separate it by colon characters (`:`) or

  //   list of labels in the path split by the '/' separator. A request is a
  //   match for path p if every p is an element-wise prefix of p of the
  //   request path. Note that if the last element of the path is a substring
  //   of the last element in request path, it is not a match (e.g. /foo/bar
  //   matches /foo/bar/baz, but does not match /foo/barbaz).
