# 경로 매개변수와 숫자 검증

`Query`를 사용하여 쿼리 매개변수에 더 많은 검증과 메타데이터를 선언하는 방법과 동일하게 `Path`를 사용하여 경로 매개변수에 검증과 메타데이터를 같은 타입으로 선언할 수 있습니다.

## 경로 임포트

먼저 `fastapi`에서 `Path`를 임포트합니다:

```Python hl_lines="3"
{!../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

## 메타데이터 선언

`Query`에 동일한 매개변수를 선언할 수 있습니다.

예를 들어, `title` 메타데이터 값을 경로 매개변수 `item_id`에 선언하려면 다음과 같이 입력할 수 있습니다:

```Python hl_lines="10"

        }
    ]
}


@needs_py39
def test_post_files(tmp_path, app: FastAPI):
    path = tmp_path / "test.txt"
    path.write_bytes(b"<file content>")
    path2 = tmp_path / "test2.txt"
    path2.write_bytes(b"<file content2>")

    client = TestClient(app)
    with path.open("rb") as file, path2.open("rb") as file2:
        response = client.post(
            "/files/",
            files=(

# パスパラメータと数値の検証

クエリパラメータに対して`Query`でより多くのバリデーションとメタデータを宣言できるのと同じように、パスパラメータに対しても`Path`で同じ種類のバリデーションとメタデータを宣言することができます。

## Pathのインポート

まず初めに、`fastapi`から`Path`をインポートします:

```Python hl_lines="1"
{!../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

## メタデータの宣言

パラメータは`Query`と同じものを宣言することができます。

例えば、パスパラメータ`item_id`に対して`title`のメタデータを宣言するには以下のようにします:

```Python hl_lines="8"

                }
            ]
        }
    )


def test_post_files(tmp_path):
    path = tmp_path / "test.txt"
    path.write_bytes(b"<file content>")
    path2 = tmp_path / "test2.txt"
    path2.write_bytes(b"<file content2>")

    client = TestClient(app)
    with path.open("rb") as file, path2.open("rb") as file2:
        response = client.post(
            "/files/",
            files=(

# Path Parameters and Numeric Validations

In the same way that you can declare more validations and metadata for query parameters with `Query`, you can declare the same type of validations and metadata for path parameters with `Path`.

## Import Path

First, import `Path` from `fastapi`, and import `Annotated`:

//// tab | Python 3.10+

```Python hl_lines="1  3"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
```

# Path Operationの高度な設定

## OpenAPI operationId

/// warning | "注意"

あなたがOpenAPIの「エキスパート」でなければ、これは必要ないかもしれません。

///

*path operation* で `operation_id` パラメータを利用することで、OpenAPIの `operationId` を設定できます。

`operation_id` は各オペレーションで一意にする必要があります。

```Python hl_lines="6"
{!../../docs_src/path_operation_advanced_configuration/tutorial001.py!}
```

### *path operation関数* の名前をoperationIdとして使用する
