# 自定义请求与 APIRoute 类

有时，我们要覆盖 `Request` 与 `APIRoute` 类使用的逻辑。

尤其是中间件里的逻辑。

例如，在应用处理请求体前，预先读取或操控请求体。

!!! danger "危险"

    本章内容**较难**。

    **FastAPI** 新手可跳过本章。

## 用例

常见用例如下：

* 把 <a href="https://msgpack.org/index.html" class="external-link" target="_blank">`msgpack`</a> 等非 JSON 请求体转换为 JSON
* 解压 gzip 压缩的请求体
* 自动记录所有请求体的日志

## 处理自定义请求体编码

下面学习如何使用自定义 `Request` 子类压缩 gizp 请求。
