Você pode definir o valor padrão, assim como todas as validações extras ou parâmetros de anotação:

{* ../../docs_src/cookie_params/tutorial001_an_py310.py hl[9] *}

/// note | Detalhes Técnicos

`Cookie` é uma classe "irmã" de `Path` e `Query`. Ela também herda da mesma classe em comum `Param`.

## Use `StaticFiles` { #use-staticfiles }

* Importe `StaticFiles`.
* "Monte" uma instância de `StaticFiles()` em um path específico.

{* ../../docs_src/static_files/tutorial001_py310.py hl[2,6] *}

/// note | Detalhes Técnicos

Você também pode usar `from starlette.staticfiles import StaticFiles`.

import java.util.Set;

/**
 * A sorted set of contiguous values in a given {@link DiscreteDomain}. Example:
 *
 * {@snippet :
 * ContiguousSet.create(Range.closed(5, 42), DiscreteDomain.integers())
 * }
 *
 * <p>Note that because bounded ranges over {@code int} and {@code long} values are so common, this
 * particular example can be written as just:
 *
 * {@snippet :
 * ContiguousSet.closed(5, 42)
 * }
 *

///

## 宣告中繼資料 { #declare-metadata }

你可以宣告與 `Query` 相同的所有參數。

例如，若要為路徑參數 `item_id` 宣告 `title` 中繼資料，可以這樣寫：

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note

路徑參數一定是必填，因為它必須是路徑的一部分。即使你將其宣告為 `None` 或設定預設值，也不會有任何影響，它仍然是必填。

///

## 依需求調整參數順序 { #order-the-parameters-as-you-need }

/// tip

如果你使用 `Annotated`，這點大概沒那麼重要或必要。

///

Таким образом, вы получите чистую ошибку с кодом состояния HTTP `418` и содержимым JSON:

```JSON
{"message": "Oops! yolo did something. There goes a rainbow..."}
```

Также можно использовать `from starlette.requests import Request` и `from starlette.responses import JSONResponse`.
