uvicorn [fastapi] python run both HTTP and HTTPS

Question

I'm trying to run a fastapi app with SSL.

I am running the app with uvicorn.

I can run the server on port 80 with HTTP,

if __name__ == '__main__':
    uvicorn.run("main:app", port=80, host='0.0.0.0', reload = True, reload_dirs = ["html_files"])

To run the port with HTTPS, I do the following,

if __name__ == '__main__':
    uvicorn.run("main:app", port=443, host='0.0.0.0', reload = True, reload_dirs = ["html_files"], ssl_keyfile="/etc/letsencrypt/live/my_domain/privkey.pem", ssl_certfile="/etc/letsencrypt/live/my_domain/fullchain.pem")

How can I run both or simply integrate https redirect?

N.B: This is a setup on a server where I don't want to use nginx, I know how to use nginx to implement https redirect.

You could use HTTPSRedirectMiddleware. This would enforce "that all incoming requests must either be https or wss. Any incoming requests to http or ws will be redirected to the secure scheme instead`.

from fastapi import FastAPI
from fastapi.middleware.httpsredirect import HTTPSRedirectMiddleware

app = FastAPI()
app.add_middleware(HTTPSRedirectMiddleware)


@app.get("/")
async def main():
    return {"message": "Hello World"}
