## Ausführen { #run-it }

/// info | Info

Das Paket <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> wird automatisch mit **FastAPI** installiert, wenn Sie den Befehl `pip install "fastapi[standard]"` ausführen.

/// tip | Совет

Если вы хотите изучить FastAPI структурированно (рекомендуется), вместо этого читайте [Учебник — Руководство пользователя](../tutorial/index.md){.internal-link target=_blank} по главам.

### 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。
