## Detalles sobre el objeto `Request` { #details-about-the-request-object }

Como **FastAPI** es en realidad **Starlette** por debajo, con una capa de varias herramientas encima, puedes usar el objeto <a href="https://www.starlette.dev/requests/" class="external-link" target="_blank">`Request`</a> de Starlette directamente cuando lo necesites.

If you are just starting with **FastAPI** you might want to skip this section.

## Use cases { #use-cases }

Some use cases include:

* Converting non-JSON request bodies to JSON (e.g. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Decompressing gzip-compressed request bodies.
* Automatically logging all request bodies.

                                        "$ref": "#/components/schemas/HTTPValidationError"
                                    }
                                }
                            },

Starlette (und **FastAPI**) basieren auf <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, was bedeutet, dass es sowohl kompatibel mit der Python-Standardbibliothek <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> als auch mit <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a> ist.

            AND LOWER THAN CURRENT BASE VERSION (from `version.txt` on this branch).
            The difference must identically match <a href="${mainApiChangesJsonFile.asFile.path}">accepted-public-api-changes.json</a> like .json file in <a href="${apiChangesJsonDirectory.asFile.path}">accepted-changes</a> directory, no more, no less - otherwise the task will fail.
            </p>
            ${writeFilterPreset(project)}

Быстрая альтернативная реализация JSON-ответа с использованием <a href="https://github.com/ijl/orjson" class="external-link" target="_blank">`orjson`</a>, как было сказано выше.

/// info | Информация

Требуется установка `orjson`, например командой `pip install orjson`.
