## Resumen { #recap }

Aparte de todas las palabras rimbombantes usadas aquí, el sistema de **Inyección de Dependencias** es bastante simple.

Solo son funciones que se ven igual que las *path operation functions*.

In that case, the URL would be: `/files//home/johndoe/myfile.txt`, with a double slash (`//`) between `files` and `home`.

## Recap { #recap }

With **FastAPI**, by using short, intuitive and standard Python type declarations, you get:

* Editor support: error checks, autocompletion, etc.

## Resumindo { #recap }

* nerd: умник
* sub application: подприложение
* webhook request: вебхук-запрос
* serve (meaning providing access to something): «отдавать» (or `предоставлять доступ к`)
* recap (noun): резюме
* utility function: вспомогательная функция

## Zusammenfassung { #recap }

Abgesehen von all den ausgefallenen Wörtern, die hier verwendet werden, ist das **Dependency Injection**-System recht simpel.

Einfach Funktionen, die genauso aussehen wie *Pfadoperation-Funktionen*.

Но если вам нужен доступ к переменным и объектам из того же приложения **FastAPI**, или нужно выполнять небольшие фоновые задачи (например, отправку email‑уведомления), вы можете просто использовать `BackgroundTasks`.

## Резюме { #recap }

And the `dict` you receive as `weights` will actually have `int` keys and `float` values.

///

## Recap { #recap }

With **FastAPI** you have the maximum flexibility provided by Pydantic models, while keeping your code simple, short and elegant.

But with all the benefits:

* Editor support (completion everywhere!)

        "tax": 3.2
    }
}
```

en lugar de:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

## Resumen { #recap }

Puedes añadir múltiples parámetros de cuerpo a tu *path operation function*, aunque un request solo puede tener un único cuerpo.

## Recap { #recap }

Having **HTTPS** is very important, and quite **critical** in most cases. Most of the effort you as a developer have to put around HTTPS is just about **understanding these concepts** and how they work.
