## Handling custom request body encodings { #handling-custom-request-body-encodings }

Let's see how to make use of a custom `Request` subclass to decompress gzip requests.

And an `APIRoute` subclass to use that custom request class.

But when the form includes files, it is encoded as `multipart/form-data`. You'll read about handling files in the next chapter.

If you want to read more about these encodings and form fields, head to the [<abbr title="Mozilla Developer Network">MDN</abbr> web docs for `POST`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/POST).

사용 사례에는 다음이 포함됩니다:

* JSON이 아닌 요청 바디를 JSON으로 변환하기(예: [`msgpack`](https://msgpack.org/index.html)).
* gzip으로 압축된 요청 바디 압축 해제하기.
* 모든 요청 바디를 자동으로 로깅하기.

## 커스텀 요청 바디 인코딩 처리하기 { #handling-custom-request-body-encodings }

커스텀 `Request` 서브클래스를 사용해 gzip 요청의 압축을 해제하는 방법을 살펴보겠습니다.

그리고 그 커스텀 요청 클래스를 사용하기 위한 `APIRoute` 서브클래스도 함께 보겠습니다.

But when the form includes files, it is encoded as `multipart/form-data`. If you use `File`, **FastAPI** will know it has to get the files from the correct part of the body.

## 使用情境 { #use-cases }

可能的使用情境包括：

* 將非 JSON 的請求本文轉換為 JSON（例如 [`msgpack`](https://msgpack.org/index.html)）。
* 解壓縮以 gzip 壓縮的請求本文。
* 自動記錄所有請求本文。

## 處理自訂請求本文編碼 { #handling-custom-request-body-encodings }

讓我們看看如何使用自訂的 `Request` 子類別來解壓縮 gzip 請求。

並透過 `APIRoute` 子類別來使用該自訂的請求類別。

### 建立自訂的 `GzipRequest` 類別 { #create-a-custom-gziprequest-class }

/// tip

ユースケースの例:

* JSON ではないリクエストボディを JSON に変換する（例: [`msgpack`](https://msgpack.org/index.html)）。
* gzip 圧縮されたリクエストボディの解凍。
* すべてのリクエストボディの自動ロギング。

## カスタムリクエストボディのエンコーディングの処理 { #handling-custom-request-body-encodings }

gzip のリクエストを解凍するために、カスタムの `Request` サブクラスを使う方法を見ていきます。

そして、そのカスタムリクエストクラスを使うための `APIRoute` サブクラスを用意します。
