## 📣 🗃

👆 💪 📣 🌐 🎏 🔢 `Query`.

🖼, 📣 `title` 🗃 💲 ➡ 🔢 `item_id` 👆 💪 🆎:

## 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"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

!!! note "참고"
    경로 매개변수는 경로의 일부여야 하므로 언제나 필수적입니다.

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

=== "Python 3.9+"

    ```Python hl_lines="1  3"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="3-4"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_an.py!}
    ```

## About HTTP status codes

!!! note
    If you already know what HTTP status codes are, skip to the next section.

In HTTP, you send a numeric status code of 3 digits as part of the response.

These status codes have a name associated to recognize them, but the important part is the number.

In short:

    ```Python hl_lines="10"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
    ```

=== "Python 3.9+"

    ```Python hl_lines="10"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_an_py39.py!}
    ```

=== "Python 3.8+"

    ```Python hl_lines="11"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_an.py!}
    ```

## 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"
{!../../../docs_src/path_params_numeric_validations/tutorial001.py!}
```

!!! note "備考"
    パスの一部でなければならないので、パスパラメータは常に必須です。

## Importe `Path`

Primeiro, importe `Path` de `fastapi`:

=== "Python 3.10+"

    ```Python hl_lines="1"
    {!> ../../../docs_src/path_params_numeric_validations/tutorial001_py310.py!}
    ```

=== "Python 3.8+"

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

## Declare metadados

Você pode declarar todos os parâmetros da mesma maneira que na `Query`.
