예를 들면, 여러분이 4개의 API 엔드포인트(*경로 작동*)를 가지고 있다고 해봅시다:

* `/items/public/`
* `/items/private/`
* `/users/{user_id}/activate`
* `/items/pro/`

그 다음 각각에 대해 그저 의존성과 하위 의존성을 사용하여 다른 권한 요구 사항을 추가할 수 있을 겁니다:

```mermaid
graph TB

current_user(["current_user"])
active_user(["active_user"])
admin_user(["admin_user"])
paying_user(["paying_user"])

public["/items/public/"]
private["/items/private/"]

En este ejemplo, cuando el cliente solicita un ítem por un ID que no existe, lanza una excepción con un código de estado de `404`:

{* ../../docs_src/handling_errors/tutorial001.py hl[11] *}

### El response resultante

Si el cliente solicita `http://example.com/items/foo` (un `item_id` `"foo"`), ese cliente recibirá un código de estado HTTP de 200, y un response JSON de:

```JSON
{
  "item": "The Foo Wrestlers"
}
```

Neste exemplo, quando o cliente pede, na requisição, por um item cujo ID não existe, a exceção com o status code `404` é lançada:

{* ../../docs_src/handling_errors/tutorial001.py hl[11] *}

### A response resultante


Se o cliente faz uma requisição para `http://example.com/items/foo` (um `item_id` `"foo"`), esse cliente receberá um HTTP status code 200, e uma resposta JSON:


```
{
  "item": "The Foo Wrestlers"
}
```

                    "message": {
                        "title": "Message",
                        "type": "string"
                    }
                }
            },
            "Item": {
                "title": "Item",
                "required": [
                    "id",
                    "value"
                ],
                "type": "object",
                "properties": {

					/></label>
				<div class="col-lg-5 col-md-8 col-sm-7 col-6">
					<la:select property="lang" styleId="langSearchOption" multiple="true" styleClass="form-control">
						<c:forEach var="item" items="${langItems}">
							<la:option value="${f:u(item.value)}">${f:h(item.label)}</la:option>
						</c:forEach>
					</la:select>
				</div>
			</div>
			<c:if test="${displayLabelTypeItems}">
				<div class="mb-3 row">

For example, let's say you define a *path operation* `/items/`:

{* ../../docs_src/behind_a_proxy/tutorial001_01.py hl[6] *}

If the client tries to go to `/items`, by default, it would be redirected to `/items/`.

But before setting the *CLI Option* `--forwarded-allow-ips` it could redirect to `http://localhost:8000/items/`.

    //                                               Details
    //                                               -------
    /**
     * Displays the details of a role item.
     *
     * @param crudMode the CRUD mode for the operation
     * @param id the ID of the role item to display
     * @return HTML response for the details page
     */
    @Execute
    @Secured({ ROLE, ROLE + VIEW })

                                                   styleClass="form-control">
                                            <c:forEach var="item" items="${protocolSchemeItems}">
                                                <la:option value="${f:u(item.value)}">${f:h(item.label)}</la:option>
                                            </c:forEach>
                                        </la:select>

}

Imaginez que vous vouliez que votre paramètre se nomme `item-query`.

Comme dans la requête :

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

Mais `item-query` n'est pas un nom de variable valide en Python.

Le nom le plus proche serait `item_query`.

Mais vous avez vraiment envie que ce soit exactement `item-query`...
