HTTPConnection class

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an HTTPConnection instead of a Request or a WebSocket.

You can import it from fastapi.requests:

from fastapi.requests import HTTPConnection

fastapi.requests.HTTPConnection

HTTPConnection(scope, receive=None)

Bases: Mapping[str, Any]

A base class for incoming HTTP connections, that is used to provide any functionality that is common to both Request and WebSocket.
