在普通的 `def` *路径操作函数*中，可以声明异步的 `async def` 依赖项；也可以在异步的 `async def` *路径操作函数*中声明普通的 `def` 依赖项。

上述这些操作都是可行的，**FastAPI** 知道该怎么处理。

/// note | "笔记"

如里不了解异步，请参阅[异步：*“着急了？”*](../../async.md){.internal-link target=_blank} 一章中 `async` 和 `await` 的内容。

## 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：

### Running a TensorFlow server

TensorFlow is a platform for distributed computing, and as such there is a
TensorFlow server (`tf.train.Server`). The TensorFlow server is intended for
internal communication only. It is not built for use in untrusted environments
or networks.

For performance reasons, the default TensorFlow server does not include any

Без Pydantic

Если вы не хотите использовать модели Pydantic, вы все еще можете использовать параметры **тела запроса**. Читайте в документации раздел [Тело - Несколько параметров: Единичные значения в теле](body-multiple-params.md#_2){.internal-link target=_blank}....

   * <p>This instance will assume ownership of {@code countMap}, and other code should not maintain

O **FastAPI** é todo baseado em Pydantic.

## Visão global

Primeiro, vamos olhar rapidamente as partes que mudam dos exemplos do **Tutorial - Guia de Usuário** para [OAuth2 com Senha (e hash), Bearer com tokens JWT](../../tutorial/security/oauth2-jwt.md){.internal-link target=_blank}. Agora utilizando escopos OAuth2:

//// tab | Python 3.10+

```Python hl_lines="5  9  13  47  65  106  108-116  122-125  129-135  140  156"
{!> ../../docs_src/security/tutorial005_an_py310.py!}
```

`app_name` 将为 `"ChimichangApp"`。

而 `items_per_user` 将保持其默认值为 `50`。

## 在另一个模块中设置

您可以将这些设置放在另一个模块文件中，就像您在[Bigger Applications - Multiple Files](../tutorial/bigger-applications.md){.internal-link target=_blank}中所见的那样。

例如，您可以创建一个名为 `config.py` 的文件，其中包含以下内容：

```Python
{!../../docs_src/settings/app01/config.py!}
```

然后在一个名为 `main.py` 的文件中使用它：

```Python hl_lines="3  11-13"
