这两个 Pydantic 模型都可以辅助验证、序列化（转换）并注释（存档）输入的数据。

因此，API 文档会显示这些数据。

## 连接与断开

* 创建 `FastAPI` 应用
* 创建事件处理器，执行数据库连接与断开操作

```Python hl_lines="42  45-47  50-52"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

## 读取笔记

创建读取笔记的*路径操作函数*：

```Python hl_lines="55-58"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

!!! Note "笔记"

## Await for messages and send messages

In your WebSocket route you can `await` for messages and send messages.

```Python hl_lines="48-52"
{!../../../docs_src/websockets/tutorial001.py!}
```

You can receive and send binary, text, and JSON data.

## Try it

If your file is named `main.py`, run your application with:

<div class="termy">

## Connect and disconnect

* Create your `FastAPI` application.
* Create event handlers to connect and disconnect from the database.

```Python hl_lines="42  45-47  50-52"
{!../../../docs_src/async_sql_databases/tutorial001.py!}
```

## Read notes

Create the *path operation function* to read notes:

```Python hl_lines="55-58"

## Nachrichten erwarten und Nachrichten senden

In Ihrer WebSocket-Route können Sie Nachrichten `await`en und Nachrichten senden.

```Python hl_lines="48-52"
{!../../../docs_src/websockets/tutorial001.py!}
```

Sie können Binär-, Text- und JSON-Daten empfangen und senden.

## Es ausprobieren

Wenn Ihre Datei `main.py` heißt, führen Sie Ihre Anwendung so aus:
