FastAPI变量查询参数 [英] FastAPI variable query parameters

问题描述

我正在编写一个快速API服务器，该服务器接受请求，检查用户是否被授权，如果成功，则将其重定向到另一个URL.

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

我需要保留URL参数，例如

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

http://localhost:80/data/?param1 = val1& param2 = val2 应该重定向到 http://some.other.api/?param1 = val1& param2 = val2 ，从而保留先前分配的参数.

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

参数不受我控制，随时可能更改.

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

我该如何实现?

代码:

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

推荐答案

在文档中，他们谈论此:

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
