La documentación interactiva de API se actualizará en consecuencia, para permitir múltiples valores:

<img src="/img/tutorial/query-params-str-validations/image02.png">

### Lista de parámetros de Query / múltiples valores con valores por defecto { #query-parameter-list-multiple-values-with-defaults }

If you open the automatic API docs, your extension will show up at the bottom of the specific *path operation*.

<img src="/img/tutorial/path-operation-advanced-configuration/image01.png">

And if you see the resulting OpenAPI (at `/openapi.json` in your API), you will see your extension as part of the specific *path operation* too:

```JSON hl_lines="22"
{
    "openapi": "3.1.0",
    "info": {

  - navigation.tracking
  - search.highlight
  - search.share
  - search.suggest
  - toc.follow

## Editor support everywhere { #editor-support-everywhere }

And you get editor support everywhere.

Even for items inside of lists:

<img src="/img/tutorial/body-nested-models/image01.png">

You couldn't get this kind of editor support if you were working directly with `dict` instead of Pydantic models.

## Поддержка редактора кода везде { #editor-support-everywhere }

И вы получаете поддержку редактора кода везде.

Даже для элементов внутри списков:

<img src="/img/tutorial/body-nested-models/image01.png">

Вы не могли бы получить такую поддержку редактора кода, если бы работали напрямую с `dict`, а не с моделями Pydantic.

```

..就像:

{* ../../docs_src/dependencies/tutorial003_py310.py hl[17] *}

但是声明类型是被鼓励的，因为那样你的编辑器就会知道将传递什么作为参数 `commons` ，然后它可以帮助你完成代码，类型检查，等等：

<img src="/img/tutorial/dependencies/image02.png">

## 快捷方式

但是您可以看到，我们在这里有一些代码重复了，编写了`CommonQueryParams`两次：

```Python
commons: CommonQueryParams = Depends(CommonQueryParams)
```

## 与 OpenAPI 集成

依赖项及子依赖项的所有请求声明、验证和需求都可以集成至同一个 OpenAPI 概图。

所以，交互文档里也会显示依赖项的所有信息：

<img src="/img/tutorial/dependencies/image01.png">

## 简单用法

观察一下就会发现，只要*路径* 和*操作*匹配，就可以使用声明的路径操作函数。然后，**FastAPI** 会用正确的参数调用函数，并提取请求中的数据。

实际上，所有（或大多数）网络框架的工作方式都是这样的。

开发人员永远都不需要直接调用这些函数，这些函数是由框架（在此为 **FastAPI** ）调用的。

have different security properties and provide different levels of confidence
when dealing with untrusted data. Based on the security history of these
libraries we consider that it is safe to work with untrusted inputs for PNG,
BMP, GIF, WAV, RAW, RAW\_PADDED, CSV and PROTO formats. All other input formats,
including tensorflow-io should be sandboxed if used to process untrusted data.

## Suporte de editor em todo canto { #editor-support-everywhere }

E você obtém suporte do editor em todos os lugares.

Mesmo para itens dentro de listas:

<img src="/img/tutorial/body-nested-models/image01.png">

Você não conseguiria este tipo de suporte de editor se estivesse trabalhando diretamente com `dict` em vez de modelos Pydantic.

现在，使用 Uvicorn 启动应用，打开 <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs。</a>

就能看到文档的*路径操作*已经包含了**回调**的内容以及*外部 API*：
