잠금 아이콘을 클릭하고 로그아웃한 다음 동일한 작업을 다시 시도하면 다음과 같은 HTTP 401 오류가 발생합니다.

```JSON
{
  "detail": "Not authenticated"
}
```

### 비활성된 유저

이제 비활성된 사용자로 시도하고, 인증해봅시다:

유저명: `alice`

패스워드: `secret2`

그리고 `/users/me` 경로와 함께 `GET` 작업을 사용해 봅시다.

다음과 같은 "Inactive user" 오류가 발생합니다:

```JSON
{
  "detail": "Inactive user"
}
```

## 요약

Wenn Sie aber im Browser <a href="http://127.0.0.1:8000/items/foo" class="external-link" target="_blank">http://127.0.0.1:8000/items/foo</a> besuchen, erhalten Sie eine hübsche HTTP-Fehlermeldung:

```JSON
{
  "detail": [
    {
      "type": "int_parsing",
      "loc": [
        "path",
        "item_id"
      ],
      "msg": "Input should be a valid integer, unable to parse string as an integer",
      "input": "foo",

requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.

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",

            ],
            "msg": "field required",
            "type": "value_error.missing"
        }
    ]
