more in the **Advanced User Guide** about how to use OAuth2 "scopes", for a more fine-grained permission system, following these same standards. OAuth2 with scopes is the mechanism used by many big authentication providers, like Facebook, Google, GitHub, Microsoft, X (Twitter), etc. to authorize third party applications to interact with their APIs on behalf of their users....

        # Don't remove en dist_path as it might already contain other languages.
        # When running build_all(), that function already removes site_path.
        # All this is only relevant locally, on GitHub Actions all this is done through
        # artifacts and multiple workflows, so it doesn't matter if directories are
        # removed or not.
    else:
        dist_path = site_path / lang

Você pode facilmente executar o experimento localmente com um prefixo de path removido usando <a href="https://docs.traefik.io/" class="external-link" target="_blank">Traefik</a>.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">Faça o download do Traefik</a>, ele é um único binário, você pode extrair o arquivo compactado e executá-lo diretamente do terminal.

Here we are declaring a `UserIn` model, it will contain a plaintext password:

{* ../../docs_src/response_model/tutorial002_py310.py hl[7,9] *}

/// info

To use `EmailStr`, first install <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

{* ../../docs_src/response_model/tutorial002_py310.py hl[7,9] *}

/// info | Informação

Para usar `EmailStr`, primeiro instale <a href="https://github.com/JoshData/python-email-validator" class="external-link" target="_blank">`email-validator`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ative-o e instale-o, por exemplo:

これは**賢明なデフォルト**を備えていますが、**環境変数**や設定ファイルを使ってすべての設定を変更したり更新したりすることができます。

また、スクリプトで<a href="https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker#pre_start_path" class="external-link" target="_blank">**開始前の事前ステップ**</a>を実行することもサポートしている。

/// tip

すべての設定とオプションを見るには、Dockerイメージのページをご覧ください: <a href="https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker" class="external-link" target="_blank">tiangolo/uvicorn-gunicorn-fastapi</a>

## 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]

## OpenAPI 客户端生成

有许多工具可以从**OpenAPI**生成客户端。

一个常见的工具是 <a href="https://openapi-generator.tech/" class="external-link" target="_blank">OpenAPI Generator</a>。

如果您正在开发**前端**，一个非常有趣的替代方案是 <a href="https://github.com/hey-api/openapi-ts" class="external-link" target="_blank">openapi-ts</a>。

## 生成一个 TypeScript 前端客户端

让我们从一个简单的 FastAPI 应用开始：
