コードから直接Uvicornサーバーを実行しているため、デバッガーから直接Pythonプログラム (FastAPIアプリケーション) を呼び出せます。

---

例えば、Visual Studio Codeでは、次のことが可能です:

* 「デバッグ」パネルに移動。
* 「構成の追加...」
* 「Python」を選択。
* オプション「`Python: Current File (Integrated Terminal)`」を指定してデバッガーを実行。

すると、**FastAPI** コードでサーバーが起動され、ブレークポイントで停止したりするでしょう。

以下の様な画面になります:

Pycharmを使用する場合、次のことが可能です:

    * UUID.
    * ...and others.

All the validation is handled by the well-established and robust **Pydantic**.

### Security and authentication { #security-and-authentication }

Security and authentication integrated. Without any compromise with databases or data models.

All the security schemes defined in OpenAPI, including:

* HTTP Basic.

# OAuth2 scopes { #oauth2-scopes }

You can use OAuth2 scopes directly with **FastAPI**, they are integrated to work seamlessly.

This would allow you to have a more fine-grained permission system, following the OAuth2 standard, integrated into your OpenAPI application (and the API docs).

          required: true
        - label: I used the GitHub search to find a similar question and didn't find it.
          required: true
        - label: I searched the FastAPI documentation, with the integrated search.
          required: true
        - label: I already searched in Google "How to X in FastAPI" and didn't find any information.
          required: true

    * If you are comparing FastAPI, compare it against a web application framework (or set of tools) that provides data validation, serialization and documentation, like Flask-apispec, NestJS, Molten, etc. Frameworks with integrated automatic data validation, serialization and documentation....

Wenn Ihnen das nichts sagt, lesen Sie den [Async: *„In Eile?“*](../../async.md#in-a-hurry){.internal-link target=_blank}-Abschnitt über `async` und `await` in der Dokumentation.

///

## Integriert in OpenAPI { #integrated-with-openapi }

Alle Requestdeklarationen, -validierungen und -anforderungen Ihrer Abhängigkeiten (und Unterabhängigkeiten) werden in dasselbe OpenAPI-Schema integriert.

Caso você não conheça, veja em [Async: *"Com Pressa?"*](../../async.md#in-a-hurry){.internal-link target=_blank} a sessão acerca de `async` e `await` na documentação.

///

## Integrando com OpenAPI { #integrated-with-openapi }

Todas as declarações de requisições, validações e requisitos para suas dependências (e sub-dependências) serão integradas em um mesmo esquema OpenAPI.

```

`app.add_middleware()` принимает класс middleware в качестве первого аргумента и любые дополнительные аргументы, которые будут переданы этому middleware.

## Встроенные middleware { #integrated-middlewares }

**FastAPI** включает несколько middleware для распространённых сценариев. Ниже рассмотрим, как их использовать.

/// note | Технические детали

```

`app.add_middleware()` recebe uma classe de middleware como o primeiro argumento e quaisquer argumentos adicionais a serem passados para o middleware.

## Middlewares Integrados { #integrated-middlewares }

**FastAPI** inclui vários middlewares para casos de uso comuns, veremos a seguir como usá-los.

/// note | Detalhes Técnicos

In the next chapters you will see how to add security to your API using those tools provided by **FastAPI**.
