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"

  // Double#doubleToRawLongBits(double)} spec.
  static final long SIGN_MASK = 0x8000000000000000L;

  static final int EXPONENT_BIAS = 1023;

  /** The implicit 1 bit that is omitted in significands of normal doubles. */
  static final long IMPLICIT_BIT = SIGNIFICAND_MASK + 1;
