FastAPIが実際にチェックしているのは、それが「呼び出し可能」（関数、クラス、その他なんでも）であり、パラメータが定義されているかどうかということです。

**FastAPI** の依存関係として「呼び出し可能なもの」を渡すと、その「呼び出し可能なもの」のパラメータを解析し、サブ依存関係も含めて、*path operation関数*のパラメータと同じように処理します。

それは、パラメータが全くない呼び出し可能なものにも適用されます。パラメータのない*path operation関数*と同じように。

そこで、上で紹介した依存関係の`common_parameters`を`CommonQueryParams`クラスに変更します:

```Python hl_lines="11 12 13 14 15"
{!../../docs_src/dependencies/tutorial002.py!}
```

			b := disk.AlignedBlock(SmallBlock)
			return &b
		},
	}
)

// WriteOnCloser implements io.WriteCloser and always
// executes at least one write operation if it is closed.
//
// This can be useful within the context of HTTP. At least
// one write operation must happen to send the HTTP headers
// to the peer.
type WriteOnCloser struct {
	io.Writer
	hasWritten bool
}

And you can declare some of the files as `bytes` and some as `UploadFile`.

/// warning

You can declare multiple `File` and `Form` parameters in a *path operation*, but you can't also declare `Body` fields that you expect to receive as JSON, as the request will have the body encoded using `multipart/form-data` instead of `application/json`.

    * Send a notification back to the API user (the external developer), as a callback.
