如何使用url_for()将数据传递到另一个路由？fastapi和jinja2

from fastapi import FastAPI, Request
from fastapi.templating import Jinja2Templates
from fastapi.staticfiles import StaticFiles
from fastapi.responses import HTMLResponse
from fastapi.routing import APIRouter
from fastapi import FastAPI, Request, Depends
from fastapi.templating import Jinja2Templates
from fastapi.staticfiles import StaticFiles
from fastapi.responses import HTMLResponse
from fastapi.routing import APIRouter
from fastapi import FastAPI, Request, Depends
from fastapi.templating import Jinja2Templates
from fastapi.staticfiles import StaticFiles
from fastapi.responses import HTMLResponse
from fastapi.routing import APIRouter

app = FastAPI()
templates = Jinja2Templates(directory="templates")
app.mount("/static", StaticFiles(directory="static"), name="static")

@app.get("/")
async def index(request: Request):
    data = {"name": "John", "age": 30}
    url = app.url_path_for("target_route", **data)
    return templates.TemplateResponse("index.html", {"request": request, "url": url})

@app.get("/target_route")
async def target_route(request: Request, name: str, age: int):
    return templates.TemplateResponse("target.html", {"request": request, "name": name, "age": age})
