 * topological sort) that only need a way of accessing the predecessors of a node in a graph.

 * <h3>Usage</h3>
 *
 * Given an algorithm, for example:
 *
 * {@snippet :
 * public <N> someGraphAlgorithm(N startNode, PredecessorsFunction<N> predecessorsFunction);

 * <p>This interface is meant to be used as the type of a parameter to graph algorithms (such as

After that, all of the processing logic is the same.

But because of our changes in `GzipRequest.body`, the request body will be automatically decompressed when it is loaded by **FastAPI** when needed.

이렇게 하면, 우리의 `GzipRequest`가 *경로 처리*로 전달하기 전에(필요하다면) 데이터의 압축 해제를 담당하게 됩니다.

그 이후의 모든 처리 로직은 동일합니다.

하지만 `GzipRequest.body`에서 변경을 했기 때문에, 필요할 때 **FastAPI**가 로드하는 시점에 요청 바디는 자동으로 압축 해제됩니다.

## 예외 핸들러에서 요청 바디 접근하기 { #accessing-the-request-body-in-an-exception-handler }

/// tip | 팁

같은 문제를 해결하려면 `RequestValidationError`에 대한 커스텀 핸들러에서 `body`를 사용하는 편이 아마 훨씬 더 쉽습니다([오류 처리하기](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)).

        // Verify cache is cleared (we can't directly test this without accessing the cache)
        // But we can test that it doesn't throw exceptions

這麼做之後，`GzipRequest` 會在把資料交給 *路徑操作* 之前（若有需要）先負責解壓縮。

之後的處理邏輯完全相同。

但由於我們修改了 `GzipRequest.body`，在 **FastAPI** 需要讀取本文時，請求本文會自動解壓縮。

## 在例外處理器中存取請求本文 { #accessing-the-request-body-in-an-exception-handler }

/// tip

要解決相同問題，使用針對 `RequestValidationError` 的自訂處理器來讀取 `body` 通常更簡單（[處理錯誤](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)）。

但本範例仍然有效，並示範了如何與內部元件互動。
