Eğer API yerine, terminalde kullanılmak üzere bir <abbr title="Komut Satırı: Command Line Interface">komut satırı uygulaması</abbr> geliştiriyorsanız <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a>'a göz atabilirsiniz.

## 创建免费 Deta 账号

创建<a href="https://www.deta.sh/?ref=fastapi" class="external-link" target="_blank">免费的 Deta 账号</a>，只需要电子邮件和密码。

甚至不需要信用卡。

## 安装 CLI

创建账号后，安装 Deta <abbr title="Command Line Interface application">CLI</abbr>：

=== "Linux, macOS"

    <div class="termy">

    ```console
    $ curl -fsSL https://get.deta.dev/cli.sh | sh
    ```

    </div>

=== "Windows PowerShell"

Ama yine de, FastAPI, Requests'ten oldukça ilham aldı.

**Requests**, <abbr title="API (Application Programming Interface): Uygulama Programlama Arayüzü">API'lar</abbr> ile bir istemci olarak *etkileşime geçmeyi* sağlayan bir kütüphaneyken **FastAPI** bir sunucu olarak <abbr title="API (Application Programming Interface): Uygulama Programlama Arayüzü">API'lar</abbr> oluşturmaya yarar.

In diesem Abschnitt werden wir sehen, wie man andere Middlewares verwendet.

## ASGI-Middleware hinzufügen

Da **FastAPI** auf Starlette basiert und die <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr>-Spezifikation implementiert, können Sie jede ASGI-Middleware verwenden.

Eine Middleware muss nicht speziell für FastAPI oder Starlette gemacht sein, um zu funktionieren, solange sie der ASGI-Spezifikation genügt.

Wenn Sie eine <abbr title="Command Line Interface – Kommandozeilen-Schnittstelle">CLI</abbr>-Anwendung für das Terminal erstellen, anstelle einer Web-API, schauen Sie sich <a href="https://typer.tiangolo.com/" class="external-link" target="_blank">**Typer**</a> an.

!!! tip
    Notice that in this case we are using a standard Python `open()` function that interacts with a file.

    So, it involves I/O (input/output), that requires "waiting" for things to be written to disk.

    But `open()` doesn't use `async` and `await`.
