# 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：

{* ../../docs_src/path_operation_configuration/tutorial001.py hl[3,17] *}

状态码在响应中使用，并会被添加到 OpenAPI 概图。

/// note | 技术细节

也可以使用 `from starlette import status` 导入状态码。

   * number of users will need this method to cover map or collection types that {@link
   * MultimapBuilder} does not support.
   *
   * <p><b>Warning: do not use</b> this method when the collections returned by {@code factory}
   * implement either {@link List} or {@code Set}! Use the more specific method {@link
