问题 I tried to run FastAPI using uvicorn webserver but it throws an error. I run this command, uvicorn api:app --reload --host 0.0.0.0 but there is an error in the terminal.

FastAPI variable query parameters

由 浪尽此生 提交于 2020-06-17 09:09:24
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
