# `Request` 직접 사용하기

지금까지 요청에서 필요한 부분을 각 타입으로 선언하여 사용해 왔습니다.

다음과 같은 곳에서 데이터를 가져왔습니다:

* 경로의 파라미터로부터.
* 헤더.
* 쿠키.
* 기타 등등.

이렇게 함으로써, **FastAPI**는 데이터를 검증하고 변환하며, API에 대한 문서를 자동화로 생성합니다.

하지만 `Request` 객체에 직접 접근해야 하는 상황이 있을 수 있습니다.

## `Request` 객체에 대한 세부 사항

- **Resource management** - Proper handling of resources with utilities like `CloseableUtil` and `DisposableUtil`

### Key Architectural Patterns
- **Factory Pattern** - `BeanDescFactory` for creating bean descriptors, `ParameterizedClassDescFactory` for generic type handling
- **Builder Pattern** - `CopyOptions` for configuring bean copying operations with fluent API

   * is transmitted. If you cannot ensure that your client and server both support HTTP/2, do not
   * use this feature.

   * ### Duplex APIs
   *
   * With regular request bodies it is not legal to write bytes to the sink passed to
   * [RequestBody.writeTo] after that method returns. For duplex requests bodies that condition is

 * [OkLog](https://github.com/simonpercic/OkLog): Response logging interceptor for OkHttp. Logs a URL link with URL-encoded response for every OkHttp call.
 * [Okurl](https://github.com/yschimke/okurl/wiki) A curl-like client for social networks and other APIs.

Es handelte sich also um ein komplett zusätzliches System.

Heutzutage ist es nicht sehr populär und wird kaum verwendet.

## OpenAPI

OpenAPI (früher bekannt als Swagger) ist die offene Spezifikation zum Erstellen von APIs (jetzt Teil der Linux Foundation).

**FastAPI** basiert auf **OpenAPI**.

Das ist es, was erlaubt, mehrere automatische interaktive Dokumentations-Oberflächen, Codegenerierung, usw. zu haben.

So, it was a complete additional system.

It is not very popular or used nowadays.
