Example Code

from fastapi import FastAPI
from fastapi.routing import APIRoute
from fastapi import Body, FastAPI, Request, Response
from typing import Callable, List

class GzipRoute(APIRoute):
    def get_route_handler(self) -> Callable:
        original_route_handler = super().get_route_handler()

        async def custom_route_handler(request: Request) -> Response:
            print("custom_route_handler called")
            return await original_route_handler(request)

        return custom_route_handler

app = FastAPI()
app.router.router_class = GzipRoute

@app.get("/")
async def root():
    return {"message": "Hello World"}

Description

as this link describe, user can get request body and do additional tasks before request go to the bussiness router functions.but it did not work in my case.I suppose it should call the function custom_route_handler,

Hi @zffocussss,

you have a typo in your code.
app.router.router_class = ... should be app.router.route_class = ...

[zffocussss]
