Здесь мы рассмотрим пример с использованием <a href="https://sqlmodel.tiangolo.com/" class="external-link" target="_blank">SQLModel</a>.

**SQLModel** построен поверх <a href="https://www.sqlalchemy.org/" class="external-link" target="_blank">SQLAlchemy</a> и Pydantic. Его создал тот же автор, что и **FastAPI**, чтобы он идеально подходил для приложений FastAPI, которым нужны **SQL базы данных**.

Sie können <a href="https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API" class="external-link" target="_blank">WebSockets</a> mit **FastAPI** verwenden.

## `websockets` installieren { #install-websockets }

## 本地测试 Traefik

您可以轻易地在本地使用 <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a> 运行移除路径前缀的试验。

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">下载 Traefik</a>，这是一个二进制文件，需要解压文件，并在 Terminal 中直接运行。

然后创建包含如下内容的 `traefik.toml` 文件：

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager" class="external-link" target="_blank">`@contextlib.contextmanager`</a> или
* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

будет корректной для использования в качестве зависимости **FastAPI**.
