そして、**FastAPI** では、Pythonのクラスを依存関係として使用することができます。

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!}
```

- All aggregation, conditional, type-conversion and string functions are supported.
- JSON path expressions such as `FROM S3Object[*].path` are not yet evaluated.
- Large numbers (outside of the signed 64-bit range) are not yet supported.

```JSON
{
    "detail": [
        {
            "loc": [
                "path",
                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

вы получите текстовую версию:

```
1 validation error
path -> item_id
  value is not a valid integer (type=type_error.integer)
```

### TLS (FTP)

Unlike SFTP server, FTP server is insecure by default. To operate under TLS mode, you need to provide certificates via

```
--ftp="tls-private-key=path/to/private.key" --ftp="tls-public-cert=path/to/public.crt"
```

> NOTE: if MinIO distributed setup is already configured to run under TLS, FTP will automatically use the relevant
