## 데이터 검증

하지만 브라우저에서 <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>로 이동하면, HTTP 오류가 잘 뜨는 것을 확인할 수 있습니다:

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

Si vous ouvrez une URL comme :

```
http://127.0.0.1:8000/items/foo-item
```

...sans ajouter le paramètre requis `needy`, vous aurez une erreur :

```JSON
{
    "detail": [
        {
            "loc": [
                "query",
                "needy"
            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
}

Если откроете браузер по адресу <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a>, то увидите интересную HTTP-ошибку:

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

## Get started

In this document we will explain in detail on how to configure multiple users.

### 1. Prerequisites

- Install mc - [MinIO Client Quickstart Guide](https://docs.min.io/community/minio-object-store/reference/minio-mc.html#quickstart)

        String url = "http://example.com/test";
        StringBuilder longMessageBuilder = new StringBuilder("Error: ");
        for (int i = 0; i < 1000; i++) {
            longMessageBuilder.append("detail ").append(i).append(" ");
        }
        String longMessage = longMessageBuilder.toString();
        Exception cause = new RuntimeException("Error cause");

## Get started

In this document we will explain in detail on how to configure all the prerequisites.

### Prerequisites

## Ejecútalo

Puedes ejecutar tus tests como de costumbre vía:

<div class="termy">

```console
$ pytest

---> 100%
```

</div>

## En Detalle

El marcador `@pytest.mark.anyio` le dice a pytest que esta función de test debe ser llamada asíncronamente:
