## 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：

			"INSERT INTO `users` (`created_at`,`updated_at`,`deleted_at`,`name`,`age`,`birthday`,`company_id`,`manager_id`,`active`) VALUES (?,?,?,?,?,?,?,?,?)",
			"SELECT * FROM `users` WHERE name = ? AND `users`.`deleted_at` IS NULL ORDER BY `users`.`id` LIMIT ?",
			"SELECT * FROM `users` WHERE name = ? AND `users`.`deleted_at` IS NULL ORDER BY `users`.`id` LIMIT ?",

    session.refresh(hero)
    return hero


@app.get("/heroes/")
def read_heroes(
    session: Session = Depends(get_session),
    offset: int = 0,
    limit: int = Query(default=100, le=100),
) -> list[Hero]:
    heroes = session.exec(select(Hero).offset(offset).limit(limit)).all()
    return heroes


@app.get("/heroes/{hero_id}")
def read_hero(hero_id: int, session: Session = Depends(get_session)) -> Hero:

                            "required": False,
                            "schema": {
                                "title": "Limit",
                                "type": "integer",
                                "default": 10,
                            },
                            "name": "limit",
                            "in": "query",
                        },
                    ],
                    "responses": {

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

MinIO server allows to throttle incoming requests:

- limit the number of active requests allowed across the cluster
- limit the wait duration for each request in the queue

These values are enabled using server's configuration or environment variables.

## Examples

### Configuring connection limit

    session.refresh(hero)
    return hero


@app.get("/heroes/")
def read_heroes(
    session: SessionDep,
    offset: int = 0,
    limit: Annotated[int, Query(le=100)] = 100,
) -> list[Hero]:
    heroes = session.exec(select(Hero).offset(offset).limit(limit)).all()
    return heroes


@app.get("/heroes/{hero_id}")
def read_hero(hero_id: int, session: SessionDep) -> Hero:
    hero = session.get(Hero, hero_id)
