## [Responses](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-response/)

The response answers the request with a code (like 200 for success or 404 for not found), headers, and its own optional body.

## Rewriting Requests

* **`400`** und darüber stehen für „Client error“-Responses („Client-Fehler“). Auch diese verwenden Sie am häufigsten.
    * Ein Beispiel ist `404`, für eine „Not Found“-Response („Nicht gefunden“).
    * Für allgemeine Fehler beim Client können Sie einfach `400` verwenden.

* **`4XX`** – статус-коды, сообщающие о клиентской ошибке. Это ещё одна наиболее часто используемая категория.
    * Пример – код `404` для статуса "Not Found".
    * Для общих ошибок со стороны клиента можно просто использовать код `400`.

## Código de Status da Resposta

Você pode definir o `status_code` (HTTP) para ser usado na resposta da sua *operação de rota*.

Você pode passar diretamente o código `int`, como `404`.

Mas se você não se lembrar o que cada código numérico significa, pode usar as constantes de atalho em `status`:
