# 路径操作配置

*路径操作装饰器*支持多种配置参数。

/// warning | "警告"

注意：以下参数应直接传递给**路径操作装饰器**，不能传递给*路径操作函数*。

///

## `status_code` 状态码

`status_code` 用于定义*路径操作*响应中的 HTTP 状态码。

可以直接传递 `int` 代码， 比如 `404`。

如果记不住数字码的涵义，也可以用 `status` 的快捷常量：

```Python hl_lines="3  17"
{!../../docs_src/path_operation_configuration/tutorial001.py!}
```

状态码在响应中使用，并会被添加到 OpenAPI 概图。

```Python hl_lines="4  10-13"
{!> ../../docs_src/schema_extra_example/tutorial002.py!}
```

/// warning

请记住，传递的那些额外参数不会添加任何验证，只会添加注释，用于文档的目的。

## `Body` 额外参数

你可以通过传递额外信息给 `Field` 同样的方式操作`Path`, `Query`, `Body`等。

比如，你可以将请求体的一个 `example` 传递给 `Body`:

만약 언더스코어를 하이픈으로 자동 변환을 비활성화해야 할 어떤 이유가 있다면, `Header`의 `convert_underscores` 매개변수를 `False`로 설정하십시오:

```Python hl_lines="10"
{!../../docs_src/header_params/tutorial002.py!}
```

/// warning | "경고"

`convert_underscore`를 `False`로 설정하기 전에, 어떤 HTTP 프록시들과 서버들은 언더스코어가 포함된 헤더 사용을 허락하지 않는다는 것을 명심하십시오.

## 중복 헤더

중복 헤더들을 수신할 수 있습니다. 즉, 다중값을 갖는 동일한 헤더를 뜻합니다.

 * will return {@code true} for many domains which (currently) are not hosts, such as {@code "com"},
 * but given that any public suffix may become a host without warning, it is better to err on the
 * side of permissiveness and thus avoid spurious rejection of valid sites. Of course, to actually
 * determine addressability of any host, clients of this class will need to perform their own DNS
