### Die resultierende Response

Wenn der Client `http://example.com/items/foo` anfragt (ein `item_id` `"foo"`), erhält dieser Client einen HTTP-Statuscode 200 und folgende JSON-Response:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Aber wenn der Client `http://example.com/items/bar` anfragt (ein nicht-existierendes `item_id` `"bar"`), erhält er einen HTTP-Statuscode 404 (der „Not Found“-Fehler), und eine JSON-Response wie folgt:

В таких случаях обычно возвращается **HTTP-код статуса ответа** в диапазоне **400** (от 400 до 499).

Они похожи на двухсотые HTTP статус-коды (от 200 до 299), которые означают, что запрос обработан успешно.

Четырёхсотые статус-коды означают, что ошибка произошла по вине клиента.

Помните ли ошибки **"404 Not Found "** (и шутки) ?

## Использование `HTTPException`

Для возврата клиенту HTTP-ответов с ошибками используется `HTTPException`.
