com um corpo JSON contendo algo como:

```JSON
{
    "description": "Payment celebration",
    "paid": true
}
```

e esperaria uma resposta daquela *API externa* com um corpo JSON como:

```JSON
{
    "ok": true
}
```

## 弃用参数 { #deprecating-parameters }

现在假设你不再喜欢这个参数了。

由于还有客户端在使用它，你不得不保留一段时间，但你希望文档清楚地将其展示为<dfn title="已过时，不推荐使用">已弃用</dfn>。

那么将参数 `deprecated=True` 传给 `Query`：

{* ../../docs_src/query_params_str_validations/tutorial010_an_py310.py hl[19] *}

文档将会像下面这样展示它：

もしくは、

もしくは、他の大文字小文字のバリエーション (アッパーケース、最初の文字だけアッパーケース、など)で、関数は `short` パラメータを `True` な `bool` 値として扱います。それ以外は `False` になります。
