That also applies to callables with no parameters at all. The same as it would be for *path operation functions* with no parameters.

Then, we can change the dependency "dependable" `common_parameters` from above to the class `CommonQueryParams`:

                                    }
                                }
                            },
                        },
                    },

# `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
```

/// tip

    * ユーザーがクエリ`q`を提供しなかった場合、クッキーに保存していた最後に使用したクエリを使用します。

### 依存関係の使用

以下のように依存関係を使用することができます:

```Python hl_lines="21"
{!../../docs_src/dependencies/tutorial005.py!}
```

/// info | "情報"

*path operation関数*の中で宣言している依存関係は`query_or_cookie_extractor`の１つだけであることに注意してください。

しかし、**FastAPI** は`query_extractor`を最初に解決し、その結果を`query_or_cookie_extractor`を呼び出す時に渡す必要があることを知っています。
