Como parte da criação do objeto de aplicação, uma *operação de rota* para `/openapi.json` (ou para o que você definir como `openapi_url`) é registrada.

Ela apenas retorna uma resposta JSON com o resultado do método `.openapi()` da aplicação.

Por padrão, o que o método `.openapi()` faz é verificar se a propriedade `.openapi_schema` tem conteúdo e retorná-lo.

                    In that case, you can publish a new snapshot from the release branch. This will update `released-versions.json` on `master`.
                    See <a href="https://bt-internal-docs.grdev.net/gbt/how-to/release/release-troubleshooting/#binary-compatibility-check-failed-">the documentation</a> for more details.

#### *列挙型メンバ*の返却 { #return-enumeration-members }

*path operation* から*列挙型メンバ*を返すことができます。JSONボディ（例: `dict`）でネストすることもできます。

それらはクライアントに返される前に適切な値 (この場合は文字列) に変換されます。

{* ../../docs_src/path_params/tutorial005_py310.py hl[18,21,23] *}

クライアントは以下の様なJSONレスポンスを得ます:

```JSON
{
  "model_name": "alexnet",
  "message": "Deep Learning FTW!"
}
```

        return false;
    }

    /**
     * Sends a 429 JSON response for API requests.
     * @param response the HTTP response
     * @throws IOException if an I/O error occurs
     */
    protected void sendApiResponse(final HttpServletResponse response) throws IOException {
        response.setStatus(429);
        response.setContentType("application/json;charset=UTF-8");

A `FastAPI` application (instance) has an `.openapi()` method that is expected to return the OpenAPI schema.

As part of the application object creation, a *path operation* for `/openapi.json` (or for whatever you set your `openapi_url`) is registered.

It just returns a JSON response with the result of the application's `.openapi()` method.
