Usando essa combinação levou a criação de vários geradores Flask _full-stack_. Há muitas _stacks_ que eu (e vários times externos) estou utilizando até agora:

* <a href="https://github.com/tiangolo/full-stack" class="external-link" target="_blank">https://github.com/tiangolo/full-stack</a>

- <a href="https://github.com/tiangolo/full-stack-flask-couchbase" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-flask-couchbase</a>
- <a href="https://github.com/tiangolo/full-stack-flask-couchdb" class="external-link" target="_blank">https://github.com/tiangolo/full-stack-flask-couchdb</a>

Ces mêmes générateurs full-stack ont servi de base aux [Générateurs de projets pour **FastAPI**](project-generation.md){.internal-link target=\_blank}.

그리고 이 작업은 `async`와 `await`를 사용하지 않으므로 일반 `def` 함수로 선언합니다.

```Python hl_lines="6-9"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

## 백그라운드 작업 추가

_경로 작동 함수_ 내에서 작업 함수를 `.add_task()` 함수 통해 _백그라운드 작업_ 개체에 전달합니다.

```Python hl_lines="14"
{!../../../docs_src/background_tasks/tutorial001.py!}
```

`.add_task()` 함수는 다음과 같은 인자를 받습니다 :

- 백그라운드에서 실행되는 작업 함수 (`write_notification`).

            body=body,
            background_tasks=background_tasks,
            response=response,
            dependency_overrides_provider=dependency_overrides_provider,
            dependency_cache=dependency_cache,
            async_exit_stack=async_exit_stack,
        )
        (
            sub_values,
            sub_errors,
            background_tasks,

Using it led to the creation of several Flask full-stack generators. These are the main stacks I (and several external teams) have been using up to now:

* <a href="https://github.com/tiangolo/full-stack" class="external-link" target="_blank">https://github.com/tiangolo/full-stack</a>

        log.write(message)


def get_query(background_tasks: BackgroundTasks, q: str | None = None):
    if q:
        message = f"found query: {q}\n"
        background_tasks.add_task(write_log, message)
    return q


@app.post("/send-notification/{email}")
async def send_notification(
    email: str, background_tasks: BackgroundTasks, q: str = Depends(get_query)
):
    message = f"message to {email}\n"

    end

    operation ->> client: Return response to client
    Note over client,operation: Response is already sent, can't change it anymore
    opt Tasks
        operation -->> tasks: Send background tasks
    end
    opt Raise other exception
        tasks -->> tasks: Handle exceptions in the background task code
    end
```

⚠️ **警告** ⚠️

如果您想从头开始创建新项目，建议使用以下备选方案。

例如，项目生成器<a href="https://github.com/tiangolo/full-stack-fastapi-postgresql" class="external-link" target="_blank">全栈 FastAPI + PostgreSQL </a>会更适用，这个项目的维护积极，用的人也多，还包括了所有新功能和改进内容。
