# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

You can import it directly from `fastapi`:

```python
from fastapi import Response
```

        // All other methods with default implementations
        @Override
        public String getAuthType() {
            return null;
        }

        @Override
        public Cookie[] getCookies() {
            return new Cookie[0];
        }

        @Override
        public long getDateHeader(String name) {
            return -1;
        }

        @Override

## `examples` en JSON Schema - OpenAPI

Cuando usas cualquiera de:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

también puedes declarar un grupo de `examples` con información adicional que se añadirá a sus **JSON Schemas** dentro de **OpenAPI**.

### `Body` con `examples`

Find ways to get great performance.

Along with Hug (as Hug is based on Falcon) inspired **FastAPI** to declare a `response` parameter in functions.

Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

## `examples` im JSON-Schema – OpenAPI

Bei Verwendung von:

* `Path()`
* `Query()`
* `Header()`
* `Cookie()`
* `Body()`
* `Form()`
* `File()`

können Sie auch eine Gruppe von `examples` mit zusätzlichen Informationen deklarieren, die zu ihren **JSON-Schemas** innerhalb von **OpenAPI** hinzugefügt werden.
