# FastAPI CLI

**FastAPI CLI**는 FastAPI 애플리케이션을 실행하고, 프로젝트를 관리하는 등 다양한 작업을 수행할 수 있는 커맨드 라인 프로그램입니다.

FastAPI를 설치할 때 (예: `pip install "fastapi[standard]"` 명령어를 사용할 경우), `fastapi-cli`라는 패키지가 포함됩니다. 이 패키지는 터미널에서 사용할 수 있는 `fastapi` 명령어를 제공합니다.

개발용으로 FastAPI 애플리케이션을 실행하려면 다음과 같이 `fastapi dev` 명령어를 사용할 수 있습니다:

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>

 * <p><b>Custom implementation</b>: Avoid implementing {@code ListenableFuture} from scratch. If you
 * can't get by with the standard implementations, prefer to derive a new {@code Future} instance
 * with the methods in {@link Futures} or, if necessary, to extend {@link AbstractFuture}.
 *

    case $link in             #(
      /*)   app_path=$link ;; #(
      *)    app_path=$APP_HOME$link ;;
    esac
done

# This is normally unused
# shellcheck disable=SC2034
APP_BASE_NAME=${0##*/}
# Discard cd standard output in case $CDPATH is set (https://github.com/gradle/gradle/issues/25036)
APP_HOME=$( cd "${APP_HOME:-./}" > /dev/null && pwd -P ) || exit

# Use the maximum available, or set MAX_FD != -1 to use that value.
MAX_FD=maximum

## Erstellen Sie Ihr Datenmodell

Dann deklarieren Sie Ihr Datenmodell als eine Klasse, die von `BaseModel` erbt.

Verwenden Sie Standard-Python-Typen für die Klassenattribute:

## Run it

/// info

The <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a> package is automatically installed with **FastAPI** when you run the `pip install "fastapi[standard]"` command.

However, if you use the `pip install fastapi` command, the `python-multipart` package is not included by default.

# OAuth2-Scopes

Sie können OAuth2-<abbr title="Geltungsbereiche">Scopes</abbr> direkt in **FastAPI** verwenden, sie sind nahtlos integriert.

Das ermöglicht es Ihnen, ein feingranuliertes Berechtigungssystem nach dem OAuth2-Standard in Ihre OpenAPI-Anwendung (und deren API-Dokumentation) zu integrieren.
