### 당신만의 비동기 코드 작성하기

Starlette(그리고 FastAPI)는 <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>를 기반으로 하고있고, 따라서 파이썬 표준 라이브러리인 <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> 및 <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>와 호환됩니다.

它看起来像这样：

您还可以使用[SQLite Viewer](https://inloop.github.io/sqlite-viewer/)或[ExtendsClass](https://extendsclass.com/sqlite-browser.html)等在线 SQLite 浏览器。

## 中间件替代数据库会话

如果你不能使用带有`yield`的依赖项——例如，如果你没有使用**Python 3.7**并且不能安装上面提到的**Python 3.6**的“backports” ——你可以使用类似的方法在“中间件”中设置会话。

“中间件”基本上是一个对每个请求都执行的函数，其中一些代码在端点函数之前执行，另一些代码在端点函数之后执行。

    /** The key of the message: {item} must be between {min} and {max}. */
    public static final String CONSTRAINTS_Range_MESSAGE = "{constraints.Range.message}";

    /** The key of the message: {item} may have unsafe html content. */
    public static final String CONSTRAINTS_SafeHtml_MESSAGE = "{constraints.SafeHtml.message}";

    /** The key of the message: script expression "{script}" didn't evaluate to true. */

    }

    /**

**FastAPI**を使用している場合、その「最初の」関数が*path operation 関数*であり、FastAPIが正しく実行する方法を知っているので、心配する必要はありません。

しかし、FastAPI以外で `async` / `await` を使用したい場合は、<a href="https://docs.python.org/3/library/asyncio-task.html#coroutine" class="external-link" target="_blank">公式Pythonドキュメントを参照して下さい</a>。

### 非同期コードの他の形式

`async` と `await` を使用するスタイルは、この言語では比較的新しいものです。

非同期コードの操作がはるかに簡単になります。
