## Обязательные query-параметры

FastAPI 通过参数名进行检测：

//// tab | Python 3.10+

```Python hl_lines="6 8"

```

////

//// tab | Python 3.8+

```Python hl_lines="8 10"

```

## 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`。

    // overlap above
    assertEquals(Range.closed(6, 8), range.intersection(Range.closed(6, 10)));

    // adjacent above
    assertEquals(Range.openClosed(8, 8), range.intersection(Range.openClosed(8, 10)));

    // separate above
    expected =
        assertThrows(
            IllegalArgumentException.class, () -> range.intersection(Range.closed(10, 12)));

Puedes declarar múltiples parámetros de path y parámetros de query al mismo tiempo. **FastAPI** sabe cuál es cuál.

No los tienes que declarar en un orden específico.

Serán detectados por nombre:

```Python hl_lines="8  10"
{!../../docs_src/query_params/tutorial004.py!}
