## Alternatives { #alternatives }

This is a simple guide to get you started and teach you how everything works **underneath**.

There are many **alternatives** to managing virtual environments, package dependencies (requirements), projects.

### Aggiornamento della documentazione alternativa

Ora vai su <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>.

* Anche la documentazione alternativa dell'API mostrerà il nuovo parametro della query e il _body_:

![ReDoc](https://fastapi.tiangolo.com/img/index/index-06-redoc-02.png)

```sh
openssl ecparam -genkey -name prime256v1 | openssl ec -out private.key
```

A response similar to this one should be displayed:

```
read EC key
writing EC key
```

Alternatively, use the following command to generate a private ECDSA key protected by a password:

```sh
openssl ecparam -genkey -name prime256v1 | openssl ec -aes256 -out private.key -passout pass:PASSWORD
```

Dem `status_code`-Parameter wird eine Zahl mit dem HTTP-Statuscode übergeben.

Alternativ kann `status_code` auch ein `IntEnum` erhalten, so wie Pythons <a href="https://docs.python.org/3/library/http.html#http.HTTPStatus" class="external-link" target="_blank">`http.HTTPStatus`</a>.

## 대안

저는 여러 해 동안 머신러닝, 분산 시스템, 비동기 작업, NoSQL 데이터베이스 같은 복잡한 요구사항을 가진 API를 개발하며 여러 팀을 이끌어 왔습니다.

이 과정에서 많은 대안을 조사하고, 테스트하며, 사용해야 했습니다. **FastAPI**의 역사는 그 이전에 나왔던 여러 도구의 역사와 밀접하게 연관되어 있습니다.

[대안](alternatives.md){.internal-link target=_blank} 섹션에서 언급된 것처럼:

> **FastAPI**는 이전에 나왔던 많은 도구들의 노력 없이는 존재하지 않았을 것입니다.
>
> 이전에 개발된 여러 도구들이 이 프로젝트에 영감을 주었습니다.

* `summary`: Pequena descrição do exemplo.
* `description`: Uma descrição longa que pode conter texto em Markdown.
* `value`: O próprio exemplo mostrado, ex: um `dict`.
* `externalValue`: alternativa ao `value`, uma URL apontando para o exemplo. Embora isso possa não ser suportado por tantas ferramentas quanto `value`.

      closed = true
      detachTimeout(timeout)
      state = STATE_READ_RESPONSE_HEADERS

..4}` this requirement added an additional burden to have sequential hostnames for us to make sure that we can provide horizontal distribution, however we have come across situations where sometimes this is not feasible and there are no easier alternatives without modifying /etc/hosts on the host system as root user.  Many times in airgapped deployments this is not allowed or requires audits and approvals.

# Clase personalizada de Request y APIRoute

En algunos casos, puede que quieras sobrescribir la lógica utilizada por las clases `Request` y `APIRoute`.

En particular, esta puede ser una buena alternativa a la lógica en un middleware.

Por ejemplo, si quieres leer o manipular el request body antes de que sea procesado por tu aplicación.

Esta es una funcionalidad "avanzada".
