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`。

## 在 `q` 參數的型別中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

Как добиться такого параллелизма в продакшн, см. раздел [Развёртывание](deployment/index.md).

## `async` и `await` { #async-and-await }

### Wie Proxy-Forwarded-Header funktionieren { #how-proxy-forwarded-headers-work }

FastAPI añadió soporte para `Annotated` (y empezó a recomendarlo) en la versión 0.95.0.

Si tienes una versión más antigua, obtendrás errores al intentar usar `Annotated`.

Asegúrate de [Actualizar la versión de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions) a al menos 0.95.1 antes de usar `Annotated`.

如果你已经有 **FastAPI Cloud** 账号（我们从候补名单邀请了你 😉），你可以用一个命令部署你的应用。

<div class="termy">

```console
$ fastapi deploy

Deploying to FastAPI Cloud...

✅ Deployment successful!

🐔 Ready the chicken! Your app is ready at https://myapp.fastapicloud.dev
