Les réponses générées au format OpenAPI pour cette *opération de chemin* seront :

```JSON hl_lines="3-12"
{
    "responses": {
        "404": {
            "description": "Additional Response",
            "content": {

                    }
                }

# Additional Status Codes

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes

///

## OpenAPIとAPIドキュメント

ステータスコードとレスポンスを直接返す場合、それらはOpenAPIスキーマ (APIドキュメント) には含まれません。なぜなら、FastAPIは何が返されるのか事前に知ることができないからです。

///

O retorno gerado no OpenAI para esta *operação de caminho* será:

```JSON hl_lines="3-12"
{
    "responses": {
        "404": {
            "description": "Additional Response",
            "content": {

                    }

**在OpenAPI中为该路径操作生成的响应将是：**

```json hl_lines="3-12"
{
    "responses": {
        "404": {
            "description": "Additional Response",
            "content": {
                "application/json": {
                    "schema": {
                        "$ref": "#/components/schemas/Message"
                    }
                }

# Additional Responses in OpenAPI

/// warning

This is a rather advanced topic.

If you are starting with **FastAPI**, you might not need this.

///

You can declare additional responses, with additional status codes, media types, descriptions, etc.

Those additional responses will be included in the OpenAPI schema, so they will also appear in the API docs.

///

Die generierten Responses in der OpenAPI für diese *Pfadoperation* lauten:

```JSON hl_lines="3-12"
{
    "responses": {
        "404": {
            "description": "Additional Response",
            "content": {
                "application/json": {
                    "schema": {
                        "$ref": "#/components/schemas/Message"
                    }
                }

directamente, estas no estarán incluidas en el schema de OpenAPI (documentación de API), porque FastAPI no tiene una manera de conocer de antemano lo que vas a devolver.

Pero puedes documentar eso en tu código usando [Respuestas Adicionales](additional-responses.md){.internal-link target=_blank}....

inclus dans le schéma OpenAPI (la documentation de l'API), car FastAPI n'a aucun moyen de savoir à l'avance ce que vous allez renvoyer.

Mais vous pouvez documenter cela dans votre code, en utilisant : [Réponses supplémentaires dans OpenAPI](additional-responses.md){.internal-link target=_blank}....
