FastAPI variable query parameters

问题

I am writing a Fast API server that accepts requests, checks if users are authorized and then redirects them to another url if successful.

I need to carry over URL parameters, e.g.

http://localhost:80/data/?param1=val1&param2=val2 should redirect to http://some.other.api/?param1=val1&param2=val2, thus keeping previously allotted parameters.

There parameters are not controlled by me and could change at any moment.

How can I achieve this?

Code:

from fastapi import FastAPI
from starlette.responses import RedirectResponse

app = FastAPI()

@app.get("/data/")
async def api_data():
    params = '' # I need this value
    url = f'http://some.other.api/{params}'
    response = RedirectResponse(url=url)
    return response

回答1:

In the docs they talk about using the Request directly, which then lead me to this:

from fastapi import FastAPI, Request
from starlette.responses import RedirectResponse

app = FastAPI()

@app.get("/data/")
async def api_data(request: Request):
    params = str(request.query_params)
    url = f'http://some.other.api/{params}'
    response = RedirectResponse(url=url)
    return response
