## `Cookie` importieren

Importieren Sie zuerst `Cookie`:

//// tab | Python 3.10+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3"

 定义 `Cookie` 参数与定义 `Query` 和 `Path` 参数一样。

## 导入 `Cookie`

首先，导入 `Cookie`：

//// tab | Python 3.10+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="3"
{!> ../../docs_src/cookie_params/tutorial001_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="3"

Portanto, em nosso exemplo, podemos fazer com que `tags` sejam especificamente uma "lista de strings":


```Python hl_lines="14"
{!../../docs_src/body_nested_models/tutorial002.py!}
```

## Tipo "set"


Mas então, quando nós pensamos mais, percebemos que as tags não devem se repetir, elas provavelmente devem ser strings únicas.
