Example Code

import typing
from starlette.types import ASGIApp
from fastapi import Request, Response
from starlette.middleware.base import BaseHTTPMiddleware, RequestResponseEndpoint, DispatchFunction


class AllowIps(BaseHTTPMiddleware):
    def __init__(self, app: ASGIApp, ips: typing.Optional[list] = None, dispatch: typing.Optional[DispatchFunction] = None) -> None:
        super().__init__(app, dispatch)
        self.ips = ips

    async def dispatch(self, request: Request, call_next: RequestResponseEndpoint) -> Response:
        response = await call_next(request)
        if request.client.host not in self.ips:
            print("xxxxxxxxxxx")
            return {"msg": "ip not allowed"}
        return response

Description

• I have a requirement that the unsatisfied ip does not allow access to my application.
• The custom middleware seems to have to return a call_next object, how can I do this.

just return Response object, and it would be solved. like this:
async def dispatch(self, request: Request, call_next: RequestResponseEndpoint) -> Response:
if request.client.host not in self.ips:
return Response("your ip not allowed")
else:
return await call_next(request)
