А пока давайте разберём важные **идеи**. Эти концепции применимы и к другим типам веб‑API. 💡

## Безопасность — HTTPS { #security-https }

В [предыдущей главе про HTTPS](https.md){.internal-link target=_blank} мы разобрались, как HTTPS обеспечивает шифрование для вашего API.

Также мы увидели, что HTTPS обычно обеспечивает компонент, **внешний** по отношению к серверу вашего приложения — **TLS Termination Proxy**.

Some other cloud providers ✨ [**sponsor FastAPI**](../help-fastapi.md#sponsor-the-author){.internal-link target=_blank} ✨ too. 🙇

You might also want to consider them to follow their guides and try their services:

## 技术细节

只是为好奇者提供的技术细节。🤓

在底层，这部分是<a href="https://asgi.readthedocs.io/en/latest/specs/lifespan.html" class="external-link" target="_blank">生命周期协议</a>的一部分，参见 ASGI 技术规范，定义了称为启动（`startup`）和关闭（`shutdown`）的事件。

包括如何处理生命周期状态，这可以用于程序的其他部分。

## 子应用

### 尝试带有依赖项的 WebSockets

如果您的文件名为 `main.py`，请使用以下命令运行应用程序：

```console
$ uvicorn main:app --reload

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

在浏览器中打开 <a href="http://127.0.0.1:8000" class="external-link" target="_blank">http://127.0.0.1:8000</a>。

更多细节查看 <a href="https://www.starlette.dev/background/" class="external-link" target="_blank">Starlette's official docs for Background Tasks</a>.

## 告诫

如果您需要执行繁重的后台计算，并且不一定需要由同一进程运行（例如，您不需要共享内存、变量等），那么使用其他更大的工具（如 <a href="https://docs.celeryq.dev" class="external-link" target="_blank">Celery</a>）可能更好。

它们往往需要更复杂的配置，即消息/作业队列管理器，如RabbitMQ或Redis，但它们允许您在多个进程中运行后台任务，甚至是在多个服务器中。

# WebSockets { #websockets }

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

## Instalar `websockets` { #install-websockets }

Asegúrate de crear un [entorno virtual](../virtual-environments.md){.internal-link target=_blank}, activarlo e instalar `websockets` (un paquete de Python que facilita usar el protocolo "WebSocket"):
