# `Request` class

You can declare a parameter in a *path operation function* or dependency to be of type `Request` and then you can access the raw request object directly, without any validation, etc.

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

    val callback: ServerSentEventReader.Callback =
      object : ServerSentEventReader.Callback {
        override fun onEvent(
          id: String?,
          type: String?,
          data: String,
        ) {
          callbacks.add(Event(id, type, data))
        }

        override fun onRetryChange(timeMs: Long) {
          callbacks.add(timeMs)
        }
      }
