# `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
```

    options:
        members:
            - scope
            - app
            - url
            - base_url
            - headers
            - query_params
            - path_params
            - cookies
            - client
            - state
            - url_for
            - client_state
            - application_state
            - receive
            - send
            - accept

    /** The key of the configuration. e.g. true */
    String COOKIE_SEARCH_PARAMETER_http_only = "cookie.search.parameter.http_only";

    /** The key of the configuration. e.g.  */
    String COOKIE_SEARCH_PARAMETER_SECURE = "cookie.search.parameter.secure";

    /** The key of the configuration. e.g. 60 */
    String COOKIE_SEARCH_PARAMETER_max_age = "cookie.search.parameter.max_age";

    * Ela depende do `query_extractor`, e atribui o valor retornado pela função ao parâmetro `q`.
* Ela também declara um cookie opcional `last_query`, do tipo `str`.
    * Se o usuário não passou nenhuma consulta `q`, a última consulta é utilizada, que foi salva em um cookie anteriormente.

## Utilizando a dependência { #use-the-dependency }

Então podemos utilizar a dependência com:

  /**
   * Configure the ApplicationContext. Not needed unless the AndroidX Startup [Initializer] is disabled, or running
   * a robolectric test.
   *
   * The functionality that will fail without a valid Context is primarily Cookies and URL Domain handling, but
   * may expand in the future.
   */
  fun initialize(applicationContext: Context) {
    if (PlatformRegistry.applicationContext == null) {

    * Depende del `query_extractor`, y asigna el valor que devuelve al parámetro `q`.
* También declara una `last_query` cookie opcional, como un `str`.
    * Si el usuario no proporcionó ningún query `q`, usamos el último query utilizado, que guardamos previamente en una cookie.

## Usa la dependencia { #use-the-dependency }

Entonces podemos usar la dependencia con:

}

public final class okhttp3/Cookie$Builder {
	public fun <init> ()V
	public final fun build ()Lokhttp3/Cookie;
	public final fun domain (Ljava/lang/String;)Lokhttp3/Cookie$Builder;
	public final fun expiresAt (J)Lokhttp3/Cookie$Builder;
	public final fun hostOnlyDomain (Ljava/lang/String;)Lokhttp3/Cookie$Builder;
	public final fun httpOnly ()Lokhttp3/Cookie$Builder;

    * It depends on the `query_extractor`, and assigns the value returned by it to the parameter `q`.
* It also declares an optional `last_query` cookie, as a `str`.
    * If the user didn't provide any query `q`, we use the last query used, which we saved to a cookie before.

## Use the dependency { #use-the-dependency }

Then we can use the dependency with:

{* ../../docs_src/dependencies/tutorial005_an_py310.py hl[23] *}

* editor (meaning component of IDE): редактор кода
* adopt (meaning start to use): использовать (or `начать использовать`)
* headers (meaning HTTP-headers): HTTP-заголовки
* cookie sessions: сессии с использованием cookie
* tested (adjective): протестированный
* middleware: middleware (don't translate, but add `промежуточный слой` if clarification is needed)
* path operation: операция пути (optionally clarify as `обработчик пути`)

{* ../../docs_src/schema_extra_example/tutorial002_py310.py hl[2,8:11] *}

## `examples` in JSON Schema - OpenAPI { #examples-in-json-schema-openapi }

When using any of:

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

you can also declare a group of `examples` with additional information that will be added to their **JSON Schemas** inside of **OpenAPI**.
