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：

    hashed_password = user_dict["hashed_password"],
)
```

### 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

{* ../../docs_src/first_steps/tutorial003_py39.py hl[7] *}

/// note | Примечание

Если вы не знаете, в чём разница, посмотрите [Асинхронность: *"Нет времени?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

///

### Шаг 5: верните содержимое { #step-5-return-the-content }

{* ../../docs_src/first_steps/tutorial001_py39.py hl[8] *}

在这个例子中，它是一个 `async` 函数。

---

你也可以将其定义为常规函数而不使用 `async def`:

{* ../../docs_src/first_steps/tutorial003.py hl[7] *}

/// note

如果你不知道两者的区别，请查阅 [并发: *赶时间吗？*](../async.md#_1){.internal-link target=_blank}。

///

### 步骤 5：返回内容

{* ../../docs_src/first_steps/tutorial001.py hl[8] *}

你可以返回一个 `dict`、`list`，像 `str`、`int` 一样的单个值，等等。

你还可以返回 Pydantic 模型（稍后你将了解更多）。
