You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

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`.

fastapi/exceptions.py

    This is for client errors, invalid authentication, invalid data, etc. Not for server
    errors in your code.

    Read more about it in the
    [FastAPI docs for WebSockets](https://fastapi.tiangolo.com/advanced/websockets/).

    ## Example

    ```python
    from typing import Annotated

    from fastapi import (
        Cookie,
        FastAPI,
        WebSocket,
        WebSocketException,
