Requests has a very simple and intuitive design, it's very easy to use, with sensible defaults. But at the same time, it's very powerful and customizable.

That's why, as said in the official website:

> Requests is one of the most downloaded Python packages of all time

The way you use it is very simple. For example, to do a `GET` request, you would write:

```Python

    "tax": 3.2,
    "tags": [
        "rock",
        "metal",
        "bar"
    ],
    "images": [
        {
            "url": "http://example.com/baz.jpg",
            "name": "The Foo live"
        },
        {
            "url": "http://example.com/dave.jpg",
            "name": "The Baz"
        }
    ]
}
```

* Logging Implementation

 Maven 3.1.0 ships bundled with {{{https://www.slf4j.org/api/org/slf4j/simple/SimpleLogger.html}SLF4J simple logger}} and since 3.5.0 {{{../maven-slf4j-provider/}Maven-customized <<<maven-slf4j-provider>>>}},
 but is ready to use other logging implementations: SLF4J is responsible for loading the implementation, referred to as

          "language-groovy",
          "maven",
          "platform-native",
          "plugin-development",
          "plugins-groovy",
          "plugins-java",
          "samples",
          "testing-native",
          "version-control",
          "workers"
        ],
        "parallelizationMethod": {
          "name": "TestDistribution"
        }
      }
    ]
  },

## Include the same router multiple times with different `prefix` { #include-the-same-router-multiple-times-with-different-prefix }

You can also use `.include_router()` multiple times with the *same* router using different prefixes.

This could be useful, for example, to expose the same API under different prefixes, e.g. `/api/v1` and `/api/latest`.

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

Pero aun así, es muy potente y te permite declarar "grafos" de dependencia anidados arbitrariamente profundos (árboles).

/// tip | Consejo

Todo esto podría no parecer tan útil con estos ejemplos simples.

Pero verás lo útil que es en los capítulos sobre **seguridad**.

### Response HTTP { #http-response }

La aplicación procesaría el request y enviaría un **response HTTP simple (sin encriptar)** al TLS Termination Proxy.

### Use the `app.dependency_overrides` attribute { #use-the-app-dependency-overrides-attribute }

For these cases, your **FastAPI** application has an attribute `app.dependency_overrides`, it is a simple `dict`.

To override a dependency for testing, you put as a key the original dependency (a function), and as the value, your dependency override (another function).

I'll show you how to **build your own image from scratch** to run a single Uvicorn process. It is a simple process and is probably what you would want to do when using a distributed container management system like **Kubernetes**.

## Recap { #recap }

Você acabou de ver o local principal para declarar type hints. Como parâmetros de função.

Este também é o principal local em que você os usaria com o **FastAPI**.

### Tipos simples { #simple-types }

Você pode declarar todos os tipos padrão de Python, não apenas `str`.

Você pode usar, por exemplo:

* `int`
* `float`
* `bool`
* `bytes`
