Par exemple, dans l'URL :

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

...les paramètres de requête sont :

* `skip` : avec une valeur de`0`
* `limit` : avec une valeur de `10`

Faisant partie de l'URL, ces valeurs sont des chaînes de caractères (`str`).

## 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

同理，把默认值设为 `None` 即可声明**可选的**查询参数：

The query is the set of key-value pairs that go after the `?` in a URL, separated by `&` characters.

For example, in the URL:

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

...the query parameters are:

* `skip`: with a value of `0`
* `limit`: with a value of `10`

As they are part of the URL, they are "naturally" strings.

위 예에서 `skip=0`과 `limit=10`은 기본값을 갖고 있습니다.

그러므로 URL로 이동하는 것은:

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

아래로 이동하는 것과 같습니다:

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

하지만 가령 아래로 이동한 경우:

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

함수의 매개변수 값은 아래가 됩니다:

* `skip=20`: URL에서 지정했기 때문입니다
* `limit=10`: 기본값이기 때문입니다

## 선택적 매개변수

			clause.Limit{Limit: &limit10, Offset: 20},
			clause.OrderBy{Columns: []clause.OrderByColumn{{Column: clause.PrimaryColumn, Desc: true}}},
		}

		for _, clause := range clauses {
			stmt.AddClause(clause)
		}

		stmt.Build("SELECT", "FROM", "WHERE", "GROUP BY", "LIMIT", "ORDER BY")
		_ = stmt.SQL.String()
	}
