## Additional media types for the main response

You can use this same `responses` parameter to add different media types for the same main response.

For example, you can add an additional media type of `image/png`, declaring that your *path operation* can return a JSON object (with media type `application/json`) or a PNG image:

 * (also known as a MIME Type or Content Type). This class also supports the concept of media ranges
 * <a href="http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1">defined by HTTP/1.1</a>.
 * As such, the {@code *} character is treated as a wildcard and is used to represent any acceptable
 * type or subtype value. A media type may not have wildcard type with a declared subtype. The

        }
    }
}
```

## Media types adicionais para o retorno principal

Você pode utilizar o mesmo parâmetro `responses` para adicionar diferentes media types para o mesmo retorno principal.

Por exemplo, você pode adicionar um media type adicional de `image/png`, declarando que a sua *operação de caminho* pode retornar um objeto JSON (com o media type `application/json`) ou uma imagem PNG:

And if that `Response` has a JSON media type (`application/json`), like is the case with the `JSONResponse` and `UJSONResponse`, the data you return will be automatically converted (and filtered) with any Pydantic `response_model` that you declared in the *path operation decorator*.

/// note

E se a `Response` tiver um media type JSON (`application/json`), como é o caso com `JSONResponse` e `UJSONResponse`, os dados que você retornar serão automaticamente convertidos (e filtrados) com qualquer `response_model` do Pydantic que for declarado em sua *função de operador de rota*.

À moins que vous ne spécifiiez explicitement un type de média différent dans votre paramètre `responses`, FastAPI supposera que la réponse a le même type de média que la classe de réponse principale (par défaut `application/json`).

Mais si vous avez spécifié une classe de réponse personnalisée avec `None` comme type de média, FastAPI utilisera `application/json` pour toute réponse supplémentaire associée à un modèle.
