You could also use `from starlette.middleware.cors import CORSMiddleware`.

**FastAPI** provides several middlewares in `fastapi.middleware` just as a convenience for you, the developer. But most of the available middlewares come directly from Starlette.

from collections.abc import Mapping, Sequence
from typing import Annotated, Any, TypedDict

from annotated_doc import Doc
from pydantic import BaseModel, create_model
from starlette.exceptions import HTTPException as StarletteHTTPException
from starlette.exceptions import WebSocketException as StarletteWebSocketException


class EndpointContext(TypedDict, total=False):
    function: str
    path: str
    file: str
    line: int

`Request` 还包含 `request.receive`，它是一个用于“接收”请求体的函数。

`scope` 字典和 `receive` 函数都是 ASGI 规范的一部分。

创建一个新的 `Request` 实例需要这两样：`scope` 和 `receive`。

想了解更多关于 `Request` 的信息，请查看 [Starlette 的 Request 文档](https://www.starlette.dev/requests/)。

///

由 `GzipRequest.get_route_handler` 返回的函数唯一不同之处是把 `Request` 转换为 `GzipRequest`。

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。

Você também pode utilizar `from starlette.responses import HTMLResponse`.

O **FastAPI** provê a mesma `starlette.responses` como `fastapi.responses` apenas como uma facilidade para você, desenvolvedor. Mas a maioria das respostas disponíveis vêm diretamente do Starlette.
