Если у вас более старая версия, при попытке использовать `Annotated` вы получите ошибки.

Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions) как минимум до 0.95.1 перед использованием `Annotated`.

## Использовать `Annotated` в типе для параметра `q` { #use-annotated-in-the-type-for-the-q-parameter }

In order to make changes to Gradle, you'll need:

* [Adoptium JDK](https://adoptium.net/temurin/archive/?version=17) (Java Development Kit) **version 17**. Fixed version is required to use [remote cache](#remote-build-cache).

Daha eski bir sürüm kullanıyorsanız `Annotated` kullanmaya çalışırken hata alırsınız.

`Annotated` kullanmadan önce FastAPI sürümünü en az 0.95.1’e yükseltmek için [FastAPI sürümünü yükseltin](../deployment/versions.md#upgrading-the-fastapi-versions).

/// info | 說明

FastAPI 自 0.95.0 版起加入並開始推薦使用 `Annotated`。

如果你的版本較舊，嘗試使用 `Annotated` 會出錯。

請先至少 [升級 FastAPI 版本](../deployment/versions.md#upgrading-the-fastapi-versions) 到 0.95.1 再使用 `Annotated`。

A **context manager** in Python is something that you can use in a `with` statement, for example, `open()` can be used as a context manager:

```Python
with open("file.txt") as file:
    file.read()
```

In recent versions of Python, there's also an **async context manager**. You would use it with `async with`:

```Python
async with lifespan(app):
    await do_stuff()
```

    async def bg(state: dict):
        state["bg"] = f"bg set - b: {state['context_b']} - a: {state['context_a']}"

    tasks.add_task(bg, state)
    return state


# Sync versions


@app.get("/sync_async")
def get_sync_async(state: str = Depends(asyncgen_state)):
    return state


@app.get("/sync_sync")
def get_sync_sync(state: str = Depends(generator_state)):
