如何在添加整个app的接口密钥后，将FastAPI中的接口路径加入白名单？

from fastapi import FastAPI, Request, HTTPException
from fastapi.responses import JSONResponse

class WhitelistMiddleware:
    def __init__(self, app: FastAPI):
        self.app = app
        self.whitelist = [
            "/api/public",
            "/api/login",
        ]
    
    async def __call__(self, request: Request, call_next):
        if request.url.path in self.whitelist:
            return await call_next(request)
        else:
            return JSONResponse(
                status_code=403,
                content={"message": "Access denied"}
            )

app = FastAPI()

@app.get("/api/public")
async def public_api():
    return {"message": "Public API"}

@app.get("/api/private")
async def private_api():
    return {"message": "Private API"}

app.middleware("http")(WhitelistMiddleware)
