/// note | 技术细节

`from starlette.requests import Request` 和 `from starlette.responses import JSONResponse` 也可以用于导入 `Request` 和 `JSONResponse`。

**FastAPI** 提供了与 `starlette.responses` 相同的 `fastapi.responses` 作为快捷方式，但大部分响应操作都可以直接从 Starlette 导入。同理，`Request` 也是如此。

///

## 覆盖默认异常处理器

**FastAPI** 自带了一些默认异常处理器。

If an incoming request does not validate correctly then a `400` response will be sent.

## `GZipMiddleware` { #gzipmiddleware }

Handles GZip responses for any request that includes `"gzip"` in the `Accept-Encoding` header.

The middleware will handle both standard and streaming responses.
