例如，如果你想在应用处理之前读取或操作请求体。

/// danger | 危险

这是一个“高级”特性。

如果你刚开始使用 **FastAPI**，可以先跳过本节。

///

## 使用场景 { #use-cases }

一些使用场景包括：

* 将非 JSON 的请求体转换为 JSON（例如 [`msgpack`](https://msgpack.org/index.html)）。
* 解压缩使用 gzip 压缩的请求体。
* 自动记录所有请求体日志。

## 处理自定义请求体编码 { #handling-custom-request-body-encodings }

来看如何用自定义的 `Request` 子类来解压 gzip 请求。

以及一个 `APIRoute` 子类来使用该自定义请求类。

     * Validates document fields and adds default values where necessary.

## Casos de Uso { #use-cases }

Alguns casos de uso incluem:

* Converter requisições não-JSON para JSON (por exemplo, [`msgpack`](https://msgpack.org/index.html)).
* Descomprimir corpos de requisição comprimidos com gzip.
* Registrar automaticamente todos os corpos de requisição.
