**FastAPI** verwendet diese *vorübergehende* Response, um die Cookies (auch Header und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den `Response`-Parameter auch in Abhängigkeiten deklarieren und darin Cookies (und Header) setzen.

## Eine `Response` direkt zurückgeben { #return-a-response-directly }

    ]
}
```

## Summary { #summary }

You can use **Pydantic models** to declare **query parameters** in **FastAPI**. 😎

/// tip

Spoiler alert: you can also use Pydantic models to declare cookies and headers, but you will read about that later in the tutorial. 🤫

# Usar el Request Directamente { #using-the-request-directly }

Hasta ahora, has estado declarando las partes del request que necesitas con sus tipos.

Tomando datos de:

* El path como parámetros.
* Headers.
* Cookies.
* etc.

Y al hacerlo, **FastAPI** está validando esos datos, convirtiéndolos y generando documentación para tu API automáticamente.

Pero hay situaciones donde podrías necesitar acceder al objeto `Request` directamente.

func TestExcludeForCompression(t *testing.T) {
	testCases := []struct {
		object string
		header http.Header
		result bool
	}{
		{
			object: "object.txt",
			header: http.Header{
				"Content-Type": []string{"application/zip"},
			},
			result: true,
		},
		{
			object: "object.zip",
			header: http.Header{
				"Content-Type": []string{"application/XYZ"},
			},
			result: true,
		},

It might also help avoid confusion for new developers that see an unused parameter in your code and could think it's unnecessary.

/// info

In this example we use invented custom headers `X-Key` and `X-Token`.

But in real cases, when implementing security, you would get more benefits from using the integrated [Security utilities (the next chapter)](../security/index.md).
