这样，在传给我们的路径操作之前，`GzipRequest` 会（在需要时）负责解压数据。

之后，其余处理逻辑完全相同。

但由于我们修改了 `GzipRequest.body`，在 **FastAPI** 需要读取时，请求体会被自动解压。

## 在异常处理器中访问请求体 { #accessing-the-request-body-in-an-exception-handler }

/// tip | 提示

要解决类似问题，使用 `RequestValidationError` 的自定义处理器中的 `body` 往往更简单（[处理错误](../tutorial/handling-errors.md#use-the-requestvalidationerror-body)）。

但本示例同样有效，并展示了如何与内部组件交互。
