# 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`:

=== "Python 3.10+"

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

Um diese zu konfigurieren, übergeben Sie das Argument `swagger_ui_parameters` beim Erstellen des `FastAPI()`-App-Objekts oder an die Funktion `get_swagger_ui_html()`.

`swagger_ui_parameters` empfängt ein Dict mit den Konfigurationen, die direkt an die Swagger-Oberfläche übergeben werden.

To configure them, pass the `swagger_ui_parameters` argument when creating the `FastAPI()` app object or to the `get_swagger_ui_html()` function.

`swagger_ui_parameters` receives a dictionary with the configurations passed to Swagger UI directly.

If you pass a "callable" as a dependency in **FastAPI**, it will analyze the parameters for that "callable", and process them in the same way as the parameters for a *path operation function*. Including sub-dependencies.

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

# `APIRouter` class

Here's the reference information for the `APIRouter` class, with all its parameters, attributes and methods.

You can import the `APIRouter` class directly from `fastapi`:

```python
from fastapi import APIRouter
```

::: fastapi.APIRouter
    options:
        members:
            - websocket
            - include_router
            - get
            - put
            - post
            - delete

* 올바른 매개변수를 가진 의존성("디펜더블") 함수를 호출합니다.
* 함수에서 결과를 받아옵니다.
* *경로 작동 함수*에 있는 매개변수에 그 결과를 할당합니다

```mermaid
graph TB

common_parameters(["common_parameters"])
read_items["/items/"]
read_users["/users/"]

common_parameters --> read_items
common_parameters --> read_users
```

이렇게 하면 공용 코드를 한번만 적어도 되며, **FastAPI**는 *경로 작동*을 위해 이에 대한 호출을 처리합니다.
