예를 들면, 여러분이 4개의 API 엔드포인트(*경로 처리*)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/"]

**GraphQL** resolve alguns casos de uso muito específicos.

Ele tem **vantagens** e **desvantagens** quando comparado a **web APIs** comuns.

Certifique-se de avaliar se os **benefícios** para o seu caso de uso compensam as **desvantagens**. 🤓

## Bibliotecas GraphQL { #graphql-libraries }

Aqui estão algumas das bibliotecas **GraphQL** que têm suporte **ASGI**. Você pode usá-las com **FastAPI**:

        if ((coreExtensions.getExtensions() != null)
                && (coreExtensions.getExtensions().size() > 0)) {
            for (Iterator iter = coreExtensions.getExtensions().iterator(); iter.hasNext(); ) {
                CoreExtension o = (CoreExtension) iter.next();
                writeCoreExtension(o, "extension", serializer);
            }
        }
        serializer.endTag(NAMESPACE, tagName);

from fastapi import FastAPI

app = FastAPI()


@app.post("/items/", status_code=201)
async def create_item(name: str):

    body_model_name = get_body_model_name(openapi, path)

    assert app.openapi()["components"]["schemas"][body_model_name] == {
        "properties": {
            "p": {
                "anyOf": [
                    {"items": {"type": "string"}, "type": "array"},
                    {"type": "null"},
                ],
                "title": "P",
            },
        },
        "title": body_model_name,
        "type": "object",

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

{* ../../docs_src/behind_a_proxy/tutorial001_01_py310.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/`.
