# `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
```

## 警告

大量のバックグラウンド計算が必要であり、必ずしも同じプロセスで実行する必要がない場合 (たとえば、メモリや変数などを共有する必要がない場合)、<a href="https://www.celeryproject.org/" class="external-link" target="_blank">Celery</a> のようなより大きな他のツールを使用するとメリットがあるかもしれません。
