## Details about the `Request` object { #details-about-the-request-object }

As **FastAPI** is actually **Starlette** underneath, with a layer of several tools on top, you can use Starlette's <a href="https://www.starlette.dev/requests/" class="external-link" target="_blank">`Request`</a> object directly when you need to.

If you want to secure your API, there are several better things you can do, for example:

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertEquals;

/**
 */
class DefaultBeanConfiguratorTest {

    private BeanConfigurator configurator;

    @BeforeEach
    void setUp() throws Exception {
        configurator = new DefaultBeanConfigurator();
    }

    @AfterEach

# 폼 모델

FastAPI에서 **Pydantic 모델**을 이용하여 **폼 필드**를 선언할 수 있습니다.

/// info | 정보

폼(Form)을 사용하려면, 먼저 <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>를 설치하세요.

[가상 환경](../virtual-environments.md){.internal-link target=_blank}을 생성하고 활성화한 다음, 아래와 같이 설치할 수 있습니다:

```console
$ pip install python-multipart
```

///

/// note | 참고

이 기능은 FastAPI 버전 `0.113.0` 이후부터 지원됩니다. 🤓
