Im obigen Beispiel haben sie die Defaultwerte `skip=0` und `limit=10`.

Wenn Sie also zur URL:

```
http://127.0.0.1:8000/items/
```

gehen, so ist das das gleiche wie die URL:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Aber wenn Sie zum Beispiel zu:

```
http://127.0.0.1:8000/items/?skip=20
```

gehen, werden die Parameter-Werte Ihrer Funktion sein:

* 数据校验
* API 文档

## 默认值

查询参数不是路径的固定内容，它是可选的，还支持默认值。

上例用 `skip=0` 和 `limit=10` 设定默认值。

访问 URL：

```
http://127.0.0.1:8000/items/
```

与访问以下地址相同：

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

但如果访问：

```
http://127.0.0.1:8000/items/?skip=20
```

查询参数的值就是：

* `skip=20`：在 URL 中设定的值
* `limit=10`：使用默认值

## 可选参数

El ejemplo arriba tiene `skip=0` y `limit=10` como los valores por defecto.

Entonces, si vas a la URL:

```
http://127.0.0.1:8000/items/
```

Sería lo mismo que ir a:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Pero, si por ejemplo vas a:

```
http://127.0.0.1:8000/items/?skip=20
```

Los valores de los parámetros en tu función serán:

No exemplo acima eles tem valores padrão de `skip=0` e `limit=10`.

Então, se você for até a URL:

```
http://127.0.0.1:8000/items/
```

Seria o mesmo que ir para:

```
http://127.0.0.1:8000/items/?skip=0&limit=10
```

Mas, se por exemplo você for para:

```
http://127.0.0.1:8000/items/?skip=20
```

Os valores dos parâmetros na sua função serão:

* `skip=20`: Por que você definiu isso na URL
