app.add_middleware(UnicornMiddleware, some_config="rainbow")
```

`app.add_middleware()` receives a middleware class as the first argument and any additional arguments to be passed to the middleware.

## Integrated middlewares { #integrated-middlewares }

**FastAPI** includes several middlewares for common use cases, we'll see next how to use them.

Например, в Visual Studio Code вы можете выполнить следующие шаги:

* Перейдите на панель "Debug".
* Выберите "Add configuration...".
* Выберите "Python"
* Запустите отладчик "`Python: Current File (Integrated Terminal)`".

Это запустит сервер с вашим **FastAPI** кодом, остановится на точках останова, и т.д.

Вот как это может выглядеть:

For example, in this application we don't use FastAPI's integrated functionality to extract the JSON Schema from Pydantic models nor the automatic validation for JSON. In fact, we are declaring the request content type as YAML, not JSON:

{* ../../docs_src/path_operation_advanced_configuration/tutorial007_py39.py hl[15:20, 22] *}

---

Por ejemplo, en Visual Studio Code, puedes:

* Ir al panel de "Debug".
* "Add configuration...".
* Seleccionar "Python".
* Ejecutar el depurador con la opción "`Python: Current File (Integrated Terminal)`".

Luego, iniciará el servidor con tu código **FastAPI**, deteniéndose en tus puntos de interrupción, etc.

Así es como podría verse:

# Use Old 403 Authentication Error Status Codes { #use-old-403-authentication-error-status-codes }

Before FastAPI version `0.122.0`, when the integrated security utilities returned an error to the client after a failed authentication, they used the HTTP status code `403 Forbidden`.

Por exemplo, no Visual Studio Code, você pode:

* Ir para o painel "Debug".
* "Add configuration...".
* Selecionar "Python"
* Executar o depurador com a opção "`Python: Current File (Integrated Terminal)`".

Em seguida, ele iniciará o servidor com seu código **FastAPI**, parará em seus pontos de interrupção, etc.

Veja como pode parecer:

For example, in Visual Studio Code, you can:

* Go to the "Debug" panel.
* "Add configuration...".
* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:

`app.add_middleware()` recibe una clase de middleware como primer argumento y cualquier argumento adicional que se le quiera pasar al middleware.

## Middlewares integrados { #integrated-middlewares }

**FastAPI** incluye varios middlewares para casos de uso común, veremos a continuación cómo usarlos.
