Feature

• APIRouter add a "name" attribute

APIRoute has a "name" attribute but APIRouter no a "name" attribute; i want APIRouter add a "name" attribute ,so i can do as that:

router = request.scope.get('router')
if router.name == '':
    print(router.routes)

What would be the router.name? The name of the class? 🤔

Also, why?

name

yes, The name of the class;
i want get the router info by request, like: router = request.scope.get('router')
but router.prefix is None;

import uvicorn
from fastapi import FastAPI, Request, APIRouter
from fastapi.routing import APIRoute

app = FastAPI()

router = APIRouter(prefix='/user')


@router.get('/{uid}')
async def user_get(uid: int, request: Request):
    print('request.url.path:', request.url.path)

    router = request.scope.get('router')

    print(type(router))

    # why router.prefix is None ???????!!!!!
    print('router.prefix:', router.prefix)

    return uid


app.include_router(router)

if __name__ == '__main__':
    uvicorn.run(app, host='0.0.0.0', port=5000, reload=False, debug=False, workers=1)

i just want get the router_info and route_info and the current function_name by request; like flask request.endpoint
but the fastapi request i just can get request.ur.path and .scope and .header and so on

Could you please explain your objective? What are you trying to solve? There's probably a way to do it already, but it's probably different from the way you are trying to achieve it.

Sorry for the long delay! 🙈 I wanted to personally address each issue/PR and they piled up through time, but now I'm checking each one in order.
