```Python

Zum Beispiel:

//// tab | Python 3.10+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="28"

Или в Python 3.10 и выше:

```Python
q: str | None = None
```

Например:

//// tab | Python 3.10+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="28"

```Python
q: str | None = None
```

Par exemple :

//// tab | Python 3.10+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="28"

    bufferB.writeUtf8("You shouldn't use my name.\n")
    operatorB.write(9, bufferB, 27)
    bufferA.writeUtf8("Dodgson, we've got Dodgson here!\n")
    operatorA.write(36, bufferA, 33)
    operatorB.read(0, bufferB, 9)
    assertThat(bufferB.readUtf8()).isEqualTo("Dodgson!\n")
    operatorA.read(9, bufferA, 27)
    assertThat(bufferA.readUtf8()).isEqualTo("You shouldn't use my name.\n")

由于默认情况下单一值被解释为查询参数，因此你不必显式地添加 `Query`，你可以仅执行以下操作：

```Python
q: str = None
```

比如：

//// tab | Python 3.10+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py310.py!}
```

////

//// tab | Python 3.9+

```Python hl_lines="27"
{!> ../../docs_src/body_multiple_params/tutorial004_an_py39.py!}
```

////

//// tab | Python 3.8+

```Python hl_lines="28"

例如，如果你需要压榨性能，你可以安装并使用 <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a> 并将响应设置为 `ORJSONResponse`。

导入你想要使用的 `Response` 类（子类）然后在 *路径操作装饰器* 中声明它。

```Python hl_lines="2 7"
{!../../docs_src/custom_response/tutorial001b.py!}
```

/// info | "提示"

参数 `response_class` 也会用来定义响应的「媒体类型」。

在这个例子中，HTTP 头的 `Content-Type` 会被设置成 `application/json`。

并且在 OpenAPI 文档中也会这样记录。
