Instead, launch an uvicorn application directly with: Note: The command is assuming that your app is available at the root of your package, look at the deploy section if you feel lost. This is a subtle but critical difference in functionality between the two, so it's important for web developers/admins to account for both scenarios.

This is what allows you to return arbitrary objects, for example database models. For cases where you need to change the redirect request method to GET, use the 303 See Other response instead.

FastAPI provides the same starlette.responses as fastapi.responses just as a convenience for you, the developer. But most of the available responses come directly from Starlette. I know this obfuscates the usage of the router, but I think it makes larger projects easier to handle.

Your base domain should include an HSTS header with the following attributes: If youre serving an additional redirect, it must include the HSTS header, not the page it redirects to.
