# Guía de Usuario Avanzada

## Características Adicionales

El [Tutorial - Guía de Usuario](../tutorial/index.md){.internal-link target=_blank} principal debe ser suficiente para darte un paseo por todas las características principales de **FastAPI**

En las secciones siguientes verás otras opciones, configuraciones, y características adicionales.

Las próximas secciones **no son necesariamente "avanzadas"**.

以下是参与帮助翻译的步骤。

#### 建议和指南

* 在当前 <a href="https://github.com/fastapi/fastapi/pulls" class="external-link" target="_blank">已有的 pull requests</a> 中查找你使用的语言，添加要求修改或同意合并的评审意见。

/// tip

你可以为已有的 pull requests <a href="https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/commenting-on-a-pull-request" class="external-link" target="_blank">添加包含修改建议的评论</a>。

Sie können das Experiment mit einem abgetrennten Pfadpräfix ganz einfach lokal ausführen, indem Sie <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a> verwenden.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Laden Sie Traefik herunter</a>, es ist eine einzelne Binärdatei, Sie können die komprimierte Datei extrahieren und sie direkt vom Terminal aus ausführen.

## 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：

Como você viu no capítulo anterior sobre [Conceitos de implantação](concepts.md){.internal-link target=_blank}, há várias estratégias que você pode usar.

Aqui mostrarei como usar o **Uvicorn** com **processos de trabalho** usando o comando `fastapi` ou o comando `uvicorn` diretamente.

/// info | "Informação"

To do that, use the standard Python type hint <a href="https://docs.python.org/3/library/typing.html#typing.Union" class="external-link" target="_blank">`typing.Union`</a>:
