HTTPConnection 类

当您想要定义应同时兼容 HTTP 和 WebSocket 的依赖项时，可以定义一个接受 HTTPConnection 类型参数，而不是 Request 或 WebSocket。

您可以从 fastapi.requests 导入它：

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.

Source code in starlette\requests.py

def __init__(self, scope: Scope, receive: Receive | None = None) -> None:
    assert scope["type"] in ("http", "websocket")
    self.scope = scope

    if url_path_provider is None:
        raise RuntimeError("The `url_for` method can only be used inside a Starlette application or with a router.")
    url_path = url_path_provider.url_path_for(name, **path_params)
    return url_path.make_absolute_url(base_url=self.base_url)
