## 사용자 정의 `Response` 반환하기
위 예제는 필요한 모든 부분을 보여주지만, 아직 유용하지는 않습니다. 사실 데이터를 직접 반환하면 **FastAPI**가 이를 `JSONResponse`에 넣고 `dict`로 변환하는 등 모든 작업을 자동으로 처리합니다.

이제, 사용자 정의 응답을 반환하는 방법을 알아보겠습니다.

예를 들어 <a href="https://en.wikipedia.org/wiki/XML" class="external-link" target="_blank">XML</a> 응답을 반환하고 싶다고 가정해보겠습니다.

XML 내용을 문자열에 넣고, 이를 `Response`에 넣어 반환할 수 있습니다:

/**
 * A list which forwards all its method calls to another list. Subclasses should override one or
 * more methods to modify the behavior of the backing list as desired per the <a

 *
 * <p>This class does not implement {@link java.util.RandomAccess}. If the delegate supports random

/**
 * A sorted multiset which forwards all its method calls to another sorted multiset. Subclasses
 * should override one or more methods to modify the behavior of the backing multiset as desired per
 * the <a href="http://en.wikipedia.org/wiki/Decorator_pattern">decorator pattern</a>.

Temel özellikleri şunlardır:

* **Hızlı**: Çok yüksek performanslı, **NodeJS** ve **Go** ile eşit düzeyde (Starlette ve Pydantic sayesinde). [En hızlı Python framework'lerinden bir tanesidir](#performans).
* **Kodlaması Hızlı**: Geliştirme hızını yaklaşık %200 ile %300 aralığında arttırır. *
* **Daha az hata**: İnsan (geliştirici) kaynaklı hataları yaklaşık %40 azaltır. *

 * string {@code "Foo<Bar>"}.

 * <p><b>Note:</b> This class is similar to {@link CharEscaper} but with one very important
 * difference. A CharEscaper can only process Java <a

 * when it encounters surrogate pairs. This class facilitates the correct escaping of all Unicode
 * characters.
