Aber wenn Sie wollen, dass ein Query-Parameter erforderlich ist, vergeben Sie einfach keinen Defaultwert:

{* ../../docs_src/query_params/tutorial005_py39.py hl[6:7] *}

Hier ist `needy` ein erforderlicher Query-Parameter vom Typ `str`.

Wenn Sie in Ihrem Browser eine URL wie:

```
http://127.0.0.1:8000/items/foo-item
```

## 必选查询参数

为不是路径参数的参数声明默认值（至此，仅有查询参数），该参数就**不是必选**的了。

如果只想把参数设为**可选**，但又不想指定参数的值，则要把默认值设为 `None`。

如果要把查询参数设置为**必选**，就不要声明默认值：

{* ../../docs_src/query_params/tutorial005.py hl[6:7] *}

这里的查询参数 `needy` 是类型为 `str` 的必选查询参数。

在浏览器中打开如下 URL：

```
http://127.0.0.1:8000/items/foo-item
```

……因为路径中没有必选参数 `needy`，返回的响应中会显示如下错误信息：

```JSON
{
    "detail": [

Fakat, bir sorgu parametresini zorunlu yapmak istiyorsanız varsayılan bir değer atamamanız yeterli olacaktır:

Burada `needy` parametresi `str` tipinden oluşan zorunlu bir sorgu parametresidir.

Porém, quando você quiser fazer com que o parâmetro de consulta seja obrigatório, você pode simplesmente não declarar nenhum valor como padrão.

{* ../../docs_src/query_params/tutorial005_py39.py hl[6:7] *}

Aqui o parâmetro de consulta `needy` é um valor obrigatório, do tipo `str`.
