How to return a file from an endpoint?

[guillaume-alvarez]

Hi!
One of the endpoints of my API should return a binary file.
Do you have any example showing how to represent this with flask-openapi3?

The responses field only accept dict or pydantic models.

Thanks!

I tried something like this and it seems to present well to users:

@api.get(
    "/screenshot",
    responses={
        HTTPStatus.OK: {"content": {"image/png": {"schema": {"type": "string", "format": "binary"}}}}
    },
    summary="Get screenshot.",
)
