**FastAPI <abbr title="command line interface - 命令行接口">CLI</abbr>** 是一个命令行程序，你可以用它来部署和运行你的 FastAPI 应用、管理 FastAPI 项目，等等。

当你安装 FastAPI（例如使用 `pip install "fastapi[standard]"`）时，会附带一个可以在终端中运行的命令行程序。

要在开发环境中运行你的 FastAPI 应用，可以使用 `fastapi dev` 命令：

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev

    "W",  # pycodestyle warnings
    "F",  # pyflakes
    "I",  # isort
    "B",  # flake8-bugbear
    "C4",  # flake8-comprehensions
    "UP",  # pyupgrade
]
ignore = [
    "E501",  # line too long, handled by black
    "B008",  # do not perform function calls in argument defaults
    "C901",  # too complex
    "W191",  # indentation contains tabs
]

[tool.ruff.lint.per-file-ignores]

			dst.WriteString(`\ufffd`)
			i += size

		}
		// U+2028 is LINE SEPARATOR.
		// U+2029 is PARAGRAPH SEPARATOR.
		// They are both technically valid characters in JSON strings,
		// but don't work in JSONP, which has to be evaluated as JavaScript,

            }
        }

        return resultBuf.toString();

    }

**FastAPI <abbr title="command line interface - 명령줄 인터페이스">CLI</abbr>**는 FastAPI 애플리케이션을 서빙하고, FastAPI 프로젝트를 관리하는 등 다양한 작업에 사용할 수 있는 커맨드 라인 프로그램입니다.

FastAPI를 설치하면(예: `pip install "fastapi[standard]"`) 터미널에서 실행할 수 있는 커맨드 라인 프로그램이 함께 제공됩니다.

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