通过浏览器访问 <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>，接收如下 HTTP 错误信息：

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

这是因为路径参数 `item_id` 的值 （`"foo"`）的类型不是 `int`。

# Path Operation Configuration { #path-operation-configuration }

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.

Daher, wenn Sie keine vergeben, wird **FastAPI** automatisch eine für „Erfolgreiche Response“ erstellen.

## 弃用*路径操作*

`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：

{* ../../docs_src/path_operation_configuration/tutorial006.py hl[16] *}

API 文档会把该路径操作标记为弃用：

下图显示了正常*路径操作*与弃用*路径操作* 的区别：

### Usar el nombre de la *path operation function* como el operationId { #using-the-path-operation-function-name-as-the-operationid }

Si quieres usar los nombres de las funciones de tus APIs como `operationId`s, puedes iterar sobre todas ellas y sobrescribir el `operation_id` de cada *path operation* usando su `APIRoute.name`.

Deberías hacerlo después de agregar todas tus *path operations*.
