## Anwendungsfälle

Einige Anwendungsfälle sind:

* Konvertieren von Nicht-JSON-Requestbodys nach JSON (z. B. <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a>).
* Dekomprimierung gzip-komprimierter Requestbodys.
* Automatisches Loggen aller Requestbodys.

## Handhaben von benutzerdefinierten Requestbody-Kodierungen

사용자 정의 헤더는 <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">'X-' 접두사를 사용</a>하여 추가할 수 있습니다.

그러나 만약 클라이언트의 브라우저에서 볼 수 있는 사용자 정의 헤더를 가지고 있다면, 그것들을 CORS 설정([CORS (Cross-Origin Resource Sharing)](cors.md){.internal-link target=_blank})에 <a href="https://www.starlette.io/middleware/#corsmiddleware" class="external-link" target="_blank">Starlette CORS 문서</a>에 명시된 `expose_headers` 매개변수를 이용하여 헤더들을 추가하여야합니다.

     * @return the target class

    public Class<?> getTargetClass() {
        return targetClass;
