# URL-адреса метаданных и документации

Вы можете настроить несколько конфигураций метаданных в вашем **FastAPI** приложении.

## Метаданные для API

Вы можете задать следующие поля, которые используются в спецификации OpenAPI и в UI автоматической документации API:

| Параметр | Тип | Описание |
|------------|--|-------------|
| `title` | `str` | Заголовок API. |
| `description` | `str` | Краткое описание API. Может быть использован Markdown. |

This will help us inside of the function with all the completion and type checks.

/// tip

You might remember that request bodies are also declared with Pydantic models.

Here **FastAPI** won't get confused because you are using `Depends`.

///

/// check

The way this dependency system is designed allows us to have different dependencies (different "dependables") that all return a `User` model.

그리고 평소처럼 원하는 객체(`dict`, 데이터베이스 모델 등)를 반환할 수 있습니다.

`response_model`을 선언했다면 반환된 객체는 여전히 필터링되고 변환됩니다.

**FastAPI**는 이 *임시* 응답 객체에서 상태 코드(쿠키와 헤더 포함)를 추출하여, `response_model`로 필터링된 반환 값을 최종 응답에 넣습니다.

prática comum ter um programa/servidor HTTP em execução no servidor (máquina, host, etc.) e gerenciar todas as partes HTTPS: enviando as solicitações HTTP descriptografadas para o aplicativo HTTP real em execução no mesmo servidor (a aplicação **FastAPI**, neste caso), pegue a resposta HTTP do aplicativo, criptografe-a usando o certificado apropriado e envie-a de volta ao cliente usando HTTPS. Este servidor é frequentemente chamado de <a href="https://en.wikipedia.org/wiki/TLS_termination_proxy"...
