## ASGI‑серверы { #asgi-servers }

Давайте немного углубимся в детали.

FastAPI использует стандарт для построения Python‑веб‑фреймворков и серверов под названием <abbr title="Asynchronous Server Gateway Interface – Асинхронный шлюзовый интерфейс сервера">ASGI</abbr>. FastAPI — ASGI-веб‑фреймворк.

这在大多数情况下都能正常运行。😎

例如，您可以使用该命令在容器、服务器等环境中启动您的 **FastAPI** 应用。

## ASGI 服务器

让我们深入了解一些细节。

FastAPI 使用了一种用于构建 Python Web 框架和服务器的标准，称为 <abbr title="Asynchronous Server Gateway Interface，异步服务器网关接口">ASGI</abbr>。FastAPI 本质上是一个 ASGI Web 框架。

要在远程服务器上运行 **FastAPI** 应用（或任何其他 ASGI 应用），您需要一个 ASGI 服务器程序，例如 **Uvicorn**。它是 `fastapi` 命令默认使用的 ASGI 服务器。

除此之外，还有其他一些可选的 ASGI 服务器，例如：
